A Star Is Born...
Legend has it that ENERGY STAR® began when the director of what was then
known as the U.S. Environmental Protection Agency's (EPA's) Atmospheric
Pollution Prevention Division conducted an informal walk-through of division
offices. He wanted to see if employees remembered to turn their computers
off when they left their workstations. He was not pleased with what he saw. He
figured that if many of his staff—staff members who were dedicated to fighting
climate change and well aware of the link between energy use and greenhouse
gas emissions—forgot or found it too inconvenient to shut off their computers,
the situation in the population at large was far worse. What was needed was
a technical solution, a way to automatically turn off or power down computers
when they were not in use...and thus, a star (or at least the twinkle of the star)
was born.
As with all good legends, there is a glimmer of truth to the story. In reality, a
core of dedicated staff members had been working for a number of years to
find cost-effective ways to reduce greenhouse gas emissions by analyzing data,
then talking with business and industry about what prevented investment in
energy efficiency and working with them to develop strategies to address those
barriers. The growing energy demand of computers stood out, prompting the
informal walk-through "audit" to help confirm the magnitude of potential energy
savings and setting the stage for the very first ENERGY STAR qualified product.
During this time, computers were becoming more and more important to
American business—they were the fastest-growing electricity load in the
commercial sector. These early computers were not geared for energy
efficiency, resulting in a negative impact on the bottom line where 30-40
percent of computers were left on after work hours. Interest in solving the
problem of excessive power consumption would result in the creation of the
ENERGY STAR program and mark the beginning of a journey to show the world
that energy-efficient technologies can contribute to a cleaner environment and
a growing economy.
Twenty years later, ENERGY STAR is a global symbol for energy efficiency. EPA
recognizes ENERGY STAR products in more than 60 categories. More than
80 percent of U.S. consumers recognize and understand the label, collectively
buying an estimated 300 million ENERGY STAR qualified products every year.

hours (kWh) of electricity is saved per year, which represents 15 percent of U.S. residential electricity use. These savings have offset the need for more than 185 additional
power plants.

The ENERGY STAR Story
Climate Change Action
The ENERGY STAR program was an early part of the U.S. strategy to address global warming by reducing
greenhouse gas emissions. It was first cited in President George H.W. Bush's 1992 Climate Action Plan,
and subsequently in the Clinton Administration's 1994 and 1997 Climate Action Plans. Both administrations
advocated creating incentives for
private industry to voluntarily undertake
emission reduction initiatives; incentives
were designed to foster market choices
that would increase energy efficiency.
Launched in 1992 as a cutting edge
public-private partnership, ENERGY
STAR was, and remains, a voluntary
program; the American people-
businesses and consumers—are the
ones who have driven its success.
"[Emissions will be reduced] by
harnessing private-market forces,
by leveraging modest government
expenditures to create a much larger
set of private-sector investments..."
-President William Jefferson Clinton, 1993
Engaging the Market to Drive Change
The ENERGY STAR program was founded on the idea that greenhouse gas emissions could be reduced
by overcoming market barriers that prevent consumers and businesses from doing what is in their
financial interest—choosing energy-efficient products. In the beginning, EPA worked with technical
experts within computer companies such as Apple, IBM Corporation, Hewlett-Packard and others1 to
develop the functional criteria necessary for a computer or monitor to earn the ENERGY STAR label.
I
1996
Exit signs were added to the program in a year when more than 100 million were in use in buildings
throughout the U.S., with an operating cost of $1 billion per year. ENERGY STAR qualified exit signs used
percent less energy.
-------
This first specification was technically attainable and most manufacturers agreed
to upgrade the majority of their product lines to ENERGY STAR, which became an
industry norm within a few years.
This pattern of engaging industry leaders early and openly was repeated as the
EN ERGY STAR program added more products in the ensuing years and involved other
stakeholders, including trade associations, environment and efficiency advocates,
utility and state efficiency program administrators, and international entities. Within
a few years, key principles emerged that have guided this collaboration ever since:
energy efficiency has to pay off for the consumer, and it cannot come at the expense
of key product features or functionality.
But defining efficient products through an ENERGY STAR specification was only part
of the solution. For the market to be changed, consumers needed to understand the
multiple benefits of efficiency; manufacturers needed to produce and label these
products, and retailers and contractors needed to showcase them to customers.
Starting in the mid-1990s, the U.S. Department of Energy (DOE) and EPA expanded
the program to include residential products such as dishwashers, refrigerators,
heating and cooling equipment and lighting. The government employed a "push-
pull" strategy, designing outreach and educational materials to build consumer
demand while simultaneously encouraging suppliers with a value proposition
to ensure that products were available and featured the ENERGY STAR label.
Eventually it became clear that to effectively reach consumers, the program needed
to leverage the "touch points" at which buyers become most engaged—identified
as predominantly retail point of sale. Many national retailers saw the value of being
a source for environmentally friendly, energy-efficient products for their customers,
but the key to success was showing them how to differentiate themselves by co-
branding with ENERGY STAR in a way that was compatible with their individual
corporate images.

ENERGY STAR
-------
The Making of an Energy Efficiency Brand
At first, the ENERGY STAR message was simple and rational: ENERGY STAR
saves energy and money. Advertising was limited to business and trade
publications and was dominated by images of computers and monitors. The
environmental message was conveyed by the logo itself—a half globe that
included the phrase "EPA Pollution Preventer."
In 1997, EPA launched the first broad outreach campaign to encourage consumers
to look for the ENERGY STAR label. Communication messages prominently
featured environmental benefits, but the focus was still money savings achieved
through superior energy efficiency. The tagline, "Saving the Earth. Saving Your
Money." was added to outreach materials, which were designed to provide
consumers with objective information about the government-backed label. The
first consumer campaign had three key messages:
ENERGY STAR saves you money and protects the environment. Use of qualified
products in your home can mean up to 30 percent savings.
The second price tag. Products have two price tags: the purchase price plus the
cost of electricity needed to use the product over its lifetime.
An easy choice. Either the product is energy efficient because it displays the
ENERGY STAR label, or it isn't.2
Making the environmental message more prominent was a natural outgrowth
of the desire to connect with a large group of consumers who had not been
linking their home energy use to its environmental impact. A public service
announcement (PSA) that aired during this period connected the dots, "If it
runs on electricity, it runs on fuel." It pointed consumers to ENERGY STAR as
a simple way to do their part, with the tagline, "Money isn't all you're saving."
An important sub-message in program outreach was that efficiency, unlike
conservation, did not imply sacrifice—just smart choices, like choosing ENERGY
STAR qualified products.
By 2000, 40 percent of U.S. households were aware of the ENERGY STAR label,
and the program was producing tremendous, measurable results—cumulatively

saving $5 million in utility bills and preventing greenhouse gas emissions
equivalent to the emissions from 10 million vehicles. But to take ENERGY STAR
to the next level, an internal review of the brand revealed the need to appeal not
only to consumer intellect but also to create an emotional connection.3
Launched in 2001, the Change campaign was just the solution. This campaign,
an integrated multimedia outreach effort (radio, TV, print), was the most
aspirational campaign to date. Through a combination of inspiring photography,
music and messaging, EPA reached out to Americans, encouraging everyone to
help protect the environment at home and at work.4
That same year, EPA conducted a full-scale review of the brand and developed
the first comprehensive branding strategy for ENERGY STAR. The logo was
redesigned to make it clearer, more visible and easier for partners to use. EPA also
made the decision to develop a distinctive brand personality, designed to make an
emotional connection with consumers.6The new logo and strategy continue to
this day, positioning ENERGY STAR as not only the smartest financial choice, but
also the right choice to make to protect the environment for future generations.
-------
Maintaining Loyalty and Relevance
Twenty years ago, the connection between energy efficiency and environmental
benefits was poorly understood by the general population; saving energy at
home often meant donning sweaters or purchasing sub-optimal technology
such as slow-to-illuminate compact fluorescent light bulbs (CFLs)—actions that
only a small segment of the population undertook.
Today, nearly all Americans agree or strongly agree that "it is important to save
energy in my home" and that "saving energy helps the environment."6 Many
believe improved appliance efficiency is important for reducing air pollution (92
percent important, 77 percent very important) and greenhouse gas emissions
(84 percent important, 66 percent very important).7 Nearly 70 percent of
households with CFL bulbs are "very likely" to purchase more and 81 percent of
households with CFLs have five or more.8
ENERGY STAR is an important part of this new landscape. More than 80 percent
of Americans now recognize the ENERGY STAR label—30 to 45 percent of
households report purchasing an ENERGY STAR qualified product in a given
year. Importantly, almost 85 percent of purchasers would recommend ENERGY
STAR to a friend.
EPA and DOE place a premium on earning and preserving that consumer loyalty,
monitoring use of the label and the in-store experience to ensure that the label
is used in a consistent and appropriate way, independently testing products
purchased off the shelf and, more recently, requiring third-party verification and
certification for all products prior to ENERGY STAR labeling.
To ensure that the ENERGY STAR label remains a reliable differentiator of energy-
efficient products, the program has a ramped-up cycle for reviewing and revising
efficiency criteria, particularly for those product categories where history has
shown that the market responds rapidly to changes. And the program continues
to evaluate and add new product categories every year.
ENERGY STAR Scores Well on
Key Brand Attributes
0 Relevance. A successful brand must offer a relevant choice to
its target audience. ENERGY STAR is relevant, allowing everyone the
opportunity and ability to make a personal contribution to protecting
our environment and reducing greenhouse gas emissions.
0 Differentation. A successful brand must offer a sufficiently
differentiated choice within the marketplace so that consumers see a
different value. ENERGY STAR is differentiated as a government-backed
program offering a compelling way to do good through the simple act
of choice, while providing financial benefits to the consumer.
0 Consistent Communications. A successful brand needs to
speak to its audience in a compelling and consistent way. Managing
all brand communications so that they deliver a similar message with a
compelling image or personality is key to developing an understanding
of the brand and its relevance. ENERGY STAR is a seemingly complex
subject, but presented with a highly approachable, straightforward
and consistent look and feel.
0 Credibility. Credibility is the backbone of a successful brand.
ENERGY STAR is fortified by the capabilities and reputation of EPA and
DOE. Today, millions of consumers and businesses choose ENERGY
STAR—demonstrating that ENERGY STAR has earned credibility in
the marketplace.

The Power of Partnership
Whether opening your utility bill or browsing the aisles of your neighborhood big-
box store, you will often spot the trademark cyan logo. A broad range of partners
is at the heart of the ENERGY STAR program's success—not only manufacturers
and their trade associations, but also the retailers that deliver ENERGY STAR
products to market, and utility and other efficiency program administrators who
engage in promoting energy-saving opportunities to their customers.
In 1995, EPA labeled the first suite of ENERGY STAR products geared toward the
residential central heating and cooling (HVAC) market. Systems then were sold
through a large, disaggregated network of heating and cooling contractors. The
Agency teamed up with the Air Conditioning Contractors of America (ACCA) to
promote ENERGY STAR messaging and sales strategies to its membership and
worked to build consumer awareness through the media. The program's first
video news release was developed and aired by local news outlets around the
country. In 1998, Sears agreed to use the ENERGY STAR logo and HVAC savings
facts in its national advertising circular on a regular basis. Sears estimated that
each print supplement reached approximately 40 million people.
It was when the program began labeling and actively promoting appliances and
lighting that the stars really began to align, solidifying partnerships with retailers
and efficiency programs. White goods—including refrigerators, dishwashers
and clothes washers—are an integral part of daily life, and lighting is a frequently
purchased, ubiquitous product; retailers devoted significant floor space to
showcasing them. Together, these product categories consumed a large
portion of the household energy budget, so operational savings associated with
ENERGY STAR were compelling; the cost premium associated with high-end

models meant retailers could make money "up-selling" consumers to ENERGY
STAR products. Sears, among the first to recognize the potential for leveraging
ENERGY STAR as a differentiator, seized the opportunity to increase sales not
only with house-brand Kenmore products, but also across all of its ENERGY
STAR qualified appliances.
In addition, in areas of the country where the electricity supply was becoming
constrained—predominantly California, the Pacific Northwest, the Northeast and
Wisconsin—regulators mandated that utilities fund energy efficiency programs
in order to avoid or delay the need to build costly power plants or buy expensive
energy from the electricity market. Appliances and lighting were prime targets
for efficiency programming, and the higher cost of the more efficient models
presented a market barrier that could be targeted by utilities through rebates
and discounts.
While utility programs presented an opportunity for retailers, they also posed
challenges. Utilities as well as state agencies were involved in delivering energy
efficiency programs, but the efficiency levels they targeted often varied by
market, as did the types of incentives offered. DOE and EPA began working
with national and regional organizations involved in efficiency programs.
Fortunately, these early partners, including the Consortium for Energy
Efficiency, the Northeast Energy Efficiency Partnership, the Northwest Energy
Efficiency Alliance and later the Midwest Energy Efficiency Alliance, were eager
to engage with the ENERGY STAR program. They understood their members'
needs and conveyed the importance of ENERGY STAR as a common platform
for educating consumers.
As more appliance retailers came on board, including those new to the market
such as The Home Depot and Lowe's Companies, investment in education and
promotion at point of sale increased. EPA began working to provide retailers
with the building blocks they needed to position ENERGY STAR in a way that
was compatible with their own brands. The Agency fostered dialogue between
retailers and the efficiency community, in light of their differing business
practices, so that common messages and educational themes could begin
to emerge.
The first ENERGY STAR partner meeting was held in 2000 to facilitate best-
practice exchange, networking, and promotion among manufacturers, retailers
and energy efficiency program sponsors. The first nationally coordinated
ENERGY STAR products promotion followed in 2001. More than 100 utilities
and other program sponsors, hundreds of retailers, and 25 manufacturers
participated. The national partner meetings and products promotions have
continued; 2011 marked the largest annual partner meeting to date, attracting
more than 620 attendees. The result: consumers nationwide know they can
count on their utility companies and local retailers to make energy efficiency
choices easy with ENERGY STAR.
Today, ENERGY STAR is a global symbol for energy efficiency. Computers,
printers, copiers and scanners that have earned the label can be found
throughout Europe and in Japan, Australia, New Zealand andTaiwan. In Canada,
almost 90 percent of the population recognizes the ENERGY STAR symbol,
where it appears on almost every product category in the program. Emerging
economies such as China and India take advantage of ENERGY STAR test
procedures and performance standards. For manufacturers of globally traded
products, consistency in standards and labels translates into one large market
for their energy-efficient models and a reduced cost of doing business.
Because of this vast network of partners, consumers and businesses throughout
the U.S. and around the world are helping to protect the environment, with the
help of ENERGY STAR.

A Platform for Energy Efficiency Programs
Marc Hoffman, Executive Director, Consortium for Energy Efficiency
Twenty years ago, energy efficiency programs were just starting to work with
each other. Program administrators quickly realized the power of voluntarily
aligning their efforts and formed the Consortium for Energy Efficiency (CEE).
Within the organization, they could work together on appliance efficiency
(and HVAC, then lighting, then motors, and so on). But to make inroads into
the mass markets, the dispersed energy efficiency programs also needed
a single, trusted brand to mark these new, more efficient products—one
that customers could easily recognize and was simple to understand. A
consumer needs to be able to easily ascertain whether a product is efficient
or not, and efficiency should just be one more factor—no cutting corners on
other product features!
When the federal government came up with the concept for ENERGY
STAR and then extended it to appliances, CEE carefully deliberated before
incorporating the brand into its own plans for advancing efficiency. Over time,
the decision of CEE members to adopt ENERGY STAR as their marketing
platform for energy efficiency has proven to be a great one. Surveys show
that ENERGY STAR is an important endorsement label for consumers and
that it plays an equally important role as the marketing platform for myriad
energy efficiency programs. CEE members—who often promote energy-
efficient products with financial incentives—depend on the continued
integrity of ENERGY STAR to achieve their energy-saving goals. In turn, CEE
members create brand traction in local service territories.
It is a win-win relationship, one that has been particularly instrumental in
leading to transformations in the market for most major household appliances.
For example, in 1993 there were practically no efficient front-loading clothes
washers in the United States. By 1999, through a combination of events—
the power of the ENERGY STAR platform, the introduction of CEE "advanced
tiers" of product energy efficiency performance, and program promotional
dollars—70 efficient models were available, and one million ENERGY STAR
clothes washers had been sold. Importantly, today all clothes washers,
dishwashers, and refrigerators use significantly less energy than they did a
decade ago, since voluntary efficiency efforts have made it easier and more
cost-effective to increase national energy efficiency standards that lock in
savings. What's even more impressive is that working together, the EPA,
DOE, CEE members, and industry continue to deliver meaningful additional
energy savings, steering consumers to more and more efficient options.
Once the energy hog of the household, today's ENERGY STAR qualified
refrigerators use less energy to operate than an incandescent bulb.
EPA maintains a brand that simply and credibly identifies cost-effective
energy-saving opportunities that do not compromise amenity or reliability. In
turn, CEE members actively promote ENERGY STAR in their energy-saving
programs, thereby simplifying energy efficiency decision-making for their
customers and helping to grow the brand. ENERGY STAR also presents
an excellent rallying point for energy efficiency organizations and industry
to work cooperatively. We consider ENERGY STAR to be America's most
trusted and recognized brand for energy efficiency.
CEE members congratulate the ENERGY STAR program and the hard work
of EPA and DOE on their efforts to grow the ENERGY STAR brand over 20
years. Thank you and here's to your ongoing success!

ENERGY STAR in Canada
Kathy Deeg, Chief, ENERGY STAR Canada, Natural Resources Canada
As ENERGY STAR'S pre-eminent international partner and administrator of
the ENERGY STAR program in Canada since 2001, we at Natural Resources
Canada (NRCan) would like to extend our congratulations on the ENERGY
STAR 20th anniversary! In 1992, you created a program that continues to
help transform our world to a more energy-efficient one. As we all know, to
remain relevant for 20 years is a major accomplishment.
Since its beginning 10 years ago, the ENERGY STAR program in Canada
now has more than 1,500 ENERGY STAR participants and supports more
than 50 eligible product categories, and we are still growing.
EPA, DOE, and NRCan have worked hard to make the program seamless
for participants on both sides of the border. Program development, product
specifications, branding and conformity assessment have been fully
supported by all.
And Canadians have responded to our outreach on ENERGY STAR. In 2010,
7 out of 10 Canadians understood the ENERGY STAR symbol, even without
a visual reference, and 89 percent recognized it in an online survey and
knew what it stood for. A Canadian discrete choice survey done in 2009
(for refrigerators and TVs) concluded that when all other product options are
the same, about 7 in 10 consumers will select the ENERGY STAR qualified
model over other models.
And these efforts have been successful where it counts most—on the
salesroom floor. In 2010, Whirlpool marketed over 450 ENERGY STAR qualified
product models in Canada, a 16 percent increase over the previous year.
Dufresne Furniture & Appliances operates stores in Ontario and Manitoba,
and all of their dishwashers and most of their refrigerators are ENERGY STAR
qualified. About 70 percent of the refrigerators that Leon's sells are ENERGY
STAR qualified, a 45 percent increase from five years ago. Samsung reports
that all its appliances sold in Canada are ENERGY STAR qualified.
We expect our collaboration with EPA and DOE to deepen in the upcoming
years. We remain amazed by the impact of the ENERGY STAR program and
the ability of industry partners to respond with products that help us meet
our energy efficiency and environmental goals.

ENERGY STAR Product Retrospective
The ENERGY STAR story has played out in different ways for different products—in some cases over
long periods of time, and in others rather quickly. For most, the story continues. For all, the interplay of
government, business, non-profit and market forces have literally changed history.
Computers and Monitors
It was 1992: a typical office information processing set-up included a CRT (cathode ray tube) monitor,
usually beige and occupying about 15x15 inches of desk space, attached by wires to a keyboard and
sitting atop or next to an equally large computer. About two percent of the U.S. population had access
to the Internet,9 and leading-edge companies were debating whether to build websites or continue to
invest in bulletin board systems to share information. Employees were becoming increasingly computer
literate, able to produce smartly desktop-published documents for spiral binding, using functions such
as "ctrl-v 4,34," a standard keystroke on an IBM desktop computer platform.
Unfortunately, those same employees for whom computers were becoming an integral part of work life
had little tolerance for shutting down and later rebooting their computers or monitors if they stepped
away from their cubicles or offices. Nor were they cognizant of the environmental impact of leaving
computers turned on. Few people understood or internalized the link between their energy use and
C02 (carbon dioxide) emissions, a leading contributor to global warming.
The Information Age was changing the way we worked, learned and interacted, and technology
was evolving rapidly to create and keep up with growing demand. Not inconsequentially, the energy
use associated with technological innovation was also on the rise. Estimates in 1990 indicated that
computers and related peripheral equipment consumed 40 billion kilowatt-hours of electricity in the
U.S.—five percent of commercial sector electricity—and were one of the fastest-growing but most
overlooked electricity loads.10
2009
When computer servers were added to the ENERGY STAR program, energy bills for data centers were
growing twice as fast as revenues, rising by 16 percent per year.11 A server that has earned the ENERGY
STAR can save as much as $480 in electricity costs, with an extra $480-$1,440 savings in associated
cooling costs.12
-------
By then, the scientific link between manmade greenhouse gas emissions and
global climate change was also well established. President George H.W. Bush
outlined in his 1992 National Action Plan for Global Climate Change several
strategies to reduce emissions by reducing energy consumption. EPA's voluntary
programs, including the ENERGY STAR computer program, were among those
strategies. Their shared mission: to demonstrate market-based approaches
for reducing greenhouse gases and other air pollutants by understanding the
barriers that limit greater investment in energy efficiency, and developing and
deploying strategies to overcome those barriers.
Lack of supply and lack of demand were identified as interrelated barriers to
greater computer efficiency:
• Among computer users there were widespread but unfounded beliefs that
turning computers off, even occasionally, shortened typical lifespan and
that using screensavers reduced electricity consumption. In addition, there
was an obvious lack of efficient product supply and no way to differentiate
energy-efficient models even if they existed.13
• Initial concerns with efficient technologies were related to adverse
effects on component lifetimes as well as cost premiums. But by 1992,
technological hurdles were less of an issue. Instead, manufacturers cited
lack of market demand for efficient products as the biggest barrier. A product
development specialist for a major computer manufacturer remarked
that they had once considered incorporating low power states into their
main-stream product line but were told by their marketing department not
to bother.14
Seeking to offer a credible way to designate energy-efficient products, EPA
initiated meetings with members of the computer industry to discuss forming
the ENERGY STAR program.The first step was to figure out a way to define and
implement energy-saving features.
EPA and stakeholders ultimately coalesced around a functional criterion: the
ability of a computer or monitor to go into a low power or "sleep" state after
a period of inactivity. Power management was not yet a product attribute for

Even with a drop in sales due to the recent economic slowdown, the race for
faster, more powerful, more highly featured computers and monitors continues.
In 2012, energy use in the U.S. associated with these products is 32 billion kWh
per year less than it might have been without EN ERGY STAR.
desktop computers and monitors.16 The first ENERGY STAR specification
required computers and monitors to consume 30 watts or less in this mode—a
70 percent savings from normal usage (integrated computers and monitors
were given a budget of 60 watts in sleep mode).
That same year, EPA rolled out the "EPA Energy Star—Pollution Preventer" logo
as a way for consumers to easily recognize efficient products from a trusted
source: the U.S. government.
18
-------
*
The government did something else to drive demand and supply for energy-
efficient computers and monitors—it became the largest procurer. On
April 21, 1993, President William Clinton issued an Executive Order directing
federal agencies to purchase ENERGY STAR computers and monitors.16 This
significantly increased the supply of ENERGY STAR qualifying products; by the
end of 1994, more than 2,000 ENERGY STAR qualified models were available,
and all major manufacturers were participating in the program.17
Since then, the ENERGY STAR computer and monitor specifications have
been revised multiple times, ratcheting down the power that computers and
monitors consume in sleep mode from 30 to 2 watts or less. They now include
requirements that power-saving features be preset and enabled to conserve
energy, and they have tackled energy-saving opportunities in other modes
such as "idle," where desktop computers spend 30-60 percent of the time
running basic default applications after the operating system and software have
completed loading. Efficiency criteria were eventually added for internal and
external power supplies, the components that convert alternating current (AC)
from the wall socket into direct current (DC) and regulate the voltage needed
to operate computers. Efficient power supplies enhance the efficiency of
computers in all operating modes.
Today, work continues on improving the efficiency of networked systems.
To address these new savings opportunities, the European Commission and
other international partners, the Natural Resources Defense Council (NRDC),
InformationTechnology Industry Council members, other program stakeholders
and EPA work collaboratively to research and coordinate development of
internationally acceptable definitions and test procedures.
As the information technology marketplace has evolved, so has the ENERGY
STAR program—expanding to cover other office products, tackling new
operational modes and usage patterns and learning along with industry how
best to manage power while responding to innovation. So far, EPA estimates
that ENERGY STAR office equipment has saved more than 500TWh (terawatt-
hours) of energy in the U.S., resulting in energy-bill savings of more than
$50 billion.

Co-Evolution of Efficient Computer Technology
and ENERGY STAR
Stephen Harper, Global Director of Environmental and Energy Policy, Intel Corporation
The ENERGY STAR program's focus on personal computer technology has
evolved in parallel to the technology itself since the introduction of the
first ENERGY STAR specification for computers in 1992. EPAs approach
to maximizing energy savings without compromising on performance or
features has been critical to the success of this longstanding partnership,
particularly given the astounding rate of change in the computer industry.
By ensuring a level playing field for manufacturers and building market demand
for energy-efficient products, ENERGY STAR has helped incentivize a rapid
and meaningful progression toward efficient computing, taking advantage
of rather than hampering industry efficiency innovations. These innovations
include massive improvement in the efficiency of the microprocessors, the
brains of modern IT equipment, which have improved by nearly 3 million
percent since 1978, in terms of the number of computations performed
per second per watt. (By contrast, automobile efficiency measured in miles
per gallon has improved only 40 percent over the same period.)* Similarly,
system level improvements such as the move away from cathode ray tubes
to LCD, and later mobile technologies that maximize battery capacity and
minimize heat, have led to increasingly efficient equipment.
Early iterations of the computer specification focused on activating power
management and driving down energy use in low power modes. Since the
start of this partnership, low power modes have dropped from more than
30 watts to less than one. Today, computer manufacturers ship their
products globally with power management capability enabled.
The program and its partners next moved to improve the efficiency of
idle mode, the state in which the device is turned on but not doing any
computational work. This focus made sense because studies showed that
the vast majority of computer-related energy is used in this state. Industry
interest in earning the ENERGY STAR with higher performing and more richly
featured products led EPA and stakeholders to categorize systems in terms
of functionality such that higher-performing systems were compared to like,
versus less capable, systems when competing for the ENERGY STAR, an
approach that ensures that consumers get both the savings and the features
they value. In addition, EPA has incorporated component-level requirements
into the ENERGY STAR specifications, such as those for internal and external
power supplies, wringing out additional energy waste and helping to drive
economies of scale in the production of more efficient components.
The synergy of underlying technology/market trends and the evolution of
the ENERGY STAR computer program have led to huge energy savings at
the same time that society's computational capacity has vastly increased.
Additional efficiency gains are possible if today's more efficient computers
(and other IT equipment), networked together, can be used to power the
Smart Grid, intelligent transportation, smart logistics systems, and building
energy management systems. Industry and EPAs ENERGY STAR program
have garnered success by collaborating for two
decades and will continue to work together to
realize future benefits. ••

ENERGY STAR Product Retrospective
Clothes Washers
The promise was there, but the market was not. In the late 1990s, efficient
horizontal-axis clothes washers, now known as "front loaders," were estimated
to use 40 percent of the energy and 60 percent of the water of a conventional
washing machine. They were gaining in popularity in Europe but represented
just two percent of the U.S. market, despite their introduction by several major
manufacturers.18 It took the small community of Bern, Kansas,
population 210, to make resource-efficient clothes washers part
of the national landscape.
Bern was chosen to participate in a cooperative venture between
the U.S. Department of Energy (DOE) and Maytag Appliances to
validate the performance and consumer acceptability of front-
loading washing machines in a real-world setting. The town was
selected because of its small size, community water supply
issues, and participant willingness and enthusiasm. In exchange
for participating, residents would receive Neptune horizontal-axis
washing machines, courtesy of Maytag, that they could keep.19
A primary goal of the study was to collect data that would be helpful
in moving the clothes-washer market toward higher efficiency
options, with the ENERGY STAR program as a likely vehicle for
market transformation. The study lasted five months and included
rigorous pre- and post-wash measurements on load size, water
use, energy use and cleaning satisfaction. It found that participating
households used, on average, 38 percent less water and 58
percent less energy with the front loader. Across load weight,
temperature settings and detergent and other additive choices,
participants found the cleaning performance of the front- loading
washers to be generally superior to that of their original machines,
irrespective of age.20 DOE had the data it needed to launch development of an
ENERGY STAR specification.
DOE, ENERGY STAR partners and other stakeholders agreed to an initial
technology-neutral specification with an Energy Factor (EF) of 2.50, more than
100 percent better than the federal minimum energy conservation standard.21
21
-------
Major manufacturers, including Maytag, Frigidaire and Miele, were quick
to introduce qualifying products. Other manufacturers followed suit with
a range of conventional and front-loading products that met the ENERGY
STAR specification. Then it was time to tackle other market barriers: lack of
awareness of efficient clothes washers and their performance benefits among
consumers, and higher initial cost.
ENERGY STAR state and utility partners began educating their customers
about the opportunity to save energy. They often coupled education with
rebates for ENERGY STAR qualified clothes washers, to help reduce the initial
cost difference between qualified and standard washers. The Consortium
for Energy Efficiency, California investor-owned utilities, Northeast Energy
Efficiency Partnerships and Northwest Energy Efficiency Alliance (NEEA)
were particularly active in rallying utilities to align education and incentives to
spread the word. For example, NEEA's ENERGY STAR Grimiest SoccerTeam
Contest invited 15,000 youth soccer coaches to submit photos of their teams
at their grimiest. NEEA hosted high-profile clinics throughout the Northwest
with U.S. Women's National SoccerTeam celebrityTiffeny Milbrett, challenging
participants to "Get Dirty, Score Big, and Clean Up with ENERGY STAR."22
The Bern study pointed out the important link between energy and water
savings—greater energy savings could be achieved in both drying and washing
if the washing machine used less water and did a good job of wringing out excess
water. In subsequent years, DOE introduced a water factor requirement and
test procedure for clothes washers. ENERGY STAR criteria for clothes washers
have been revised several times to respond to changing market conditions and
to help ensure meaningful additional energy savings to consumers each time
federal minimum efficiency standards change.
According to a national study by the U.S. Energy Information Agency, in 2009,
41 million households—36 percent of all U.S. households—had ENERGY STAR
qualified clothes washers in their homes.23 Altogether, about 30 billion kWh
and 110 trillion Btu of energy have been saved, avoiding more than 25 million
metric tons of greenhouse gas emissions.

A Catalyst for Change: ENERGY STAR Appliances
Nick Gillespie, Government Relations Senior Specialist, Whirlpool Corporation
Throughout the last 20 years, ENERGY STAR has been the market transformation
program catalyzing manufacturers to introduce eco-efficient appliances into
the market place that significantly benefit the consumer and the environment.
Although ENERGY STAR is a voluntary program, it did not take long for
Whirlpool Corporation to see the potential in and help formulate what has
become one of the most recognizable brands of its kind.
To put this in perspective, the 2011 KitchenAid and Maytag brand, ENERGY
STAR qualified, side-by-side refrigerators use less energy than a 60-watt
light bulb. This is more than a 60 percent improvement in energy efficiency
since the ENERGY STAR program was introduced 20 years ago. The total
production of ENERGY STAR clothes washers, refrigerators and dishwashers
made by Whirlpool Corporation in 2011 will save consumers more than $750
million in operating costs each year, when compared to the old products they
replaced. That is an astounding $11 billion over the life of these products.
The ENERGY STAR program played a pivotal role in creating this opportunity.
Our ongoing commitment to the growth, success and integrity of the ENERGY
STAR partnership has been a strong source of pride for Whirlpool Corporation
for the last 20 years. Whirlpool is celebrating its 100th anniversary and salutes
ENERGY STAR on its 20th. As our company embarks on its next century of
"every home...everywhere," there is no end to what our partnership with
ENERGY STAR can accomplish for the consumer and the planet.

ENERGY STAR Product Retrospective
Residential Lighting
Though credited with the invention of the electric light bulb, Thomas Alva Edison did not actually file
U.S. Patent 223,898 until January 27, 1880—75 years after the fundamental technology and
principles of electric light were developed. Most early light bulbs were not commercially
viable because they did not last very long and were too expensive to produce. Edison's
patent was for an improvement in electric lamps—"giving light by incandescence"—and
their method of manufacture.24 After many decades, bulb technology improved significantly
and cost decreased. Use in the U.S. began to skyrocket.
The downside to this great American success story is that lighting now uses a great deal
of energy—about 12 percent of residential energy consumption goes to lighting—and
much of that energy is converted to wasted heat, not light. In traditional incandescent
bulbs, which work by heating a filament until it becomes hot enough to emit light,
only 10 percent of the energy output produces useful light. The good news is that a
growing number of consumers are seeking more efficient ENERGY STAR qualified
fixtures and light bulbs to illuminate their homes, lower their energy bills and reduce
their carbon footprints.
As with Edison's electric light, much of the growth in more efficient lighting
has come through concerted efforts to improve light quality and increase the
longevity of efficient lighting options. As demand has grown, prices have
decreased significantly, offering an attractive payback for consumers.
But as they say, Rome wasn't built in a day...

Like the incandescent bulb, fluorescent lighting was invented long before
it became commercially viable. General Electric (GE) bought the patent for
fluorescent bulb technology in 1938 and showcased the technology and its
superior efficiency at the 1939 World's Fair in New York.26 While there was
some uptake of fluorescent lighting in the commercial sector, due to size,
shape, color (the light appeared green) and other factors, early fluorescent
lighting was not a great match for most residential applications. The
1970s saw advancements in light bulb design by several manufacturers
addressing some of the size and color concerns, and by the late
1980s, utility companies and other energy efficiency program
sponsors began promoting CFLs to their residential customers as a
way to save energy.
Despite these efforts, light bulb usage had not changed much
by the 1990s. CFLs accounted for less than one percent of
light bulb sales nationally in 1993.26 Unfortunately, the early-
model CFLs were not quite ready for prime time, with a host
of technical challenges including bulkiness, low light output,
and inconsistent performance,27 and they were expensive,
averaging $19 each in 1996,28 according to some studies.
Other market barriers identified at the time included:
• Lack of product performance standards
to support efficiency claims
• A segmented U.S. lighting industry that
saw itself as responding to consumer
demand, not creating it
• Lack of consumer awareness and
education
• Lack of coordination among
manufacturers, utilities and retailers

In the years after CFLs were added to the ENERGY STAR program, an increase
in sales led to economies of scale that lowered product costs and brought the
purchase price down dramatically. Lower prices and improved performance
led to the first peak in sales in 2007, when media attention around the danger
of global warming was high. That same year, Walmart sold 100 million CFLs.
Today, ENERGY STAR qualified CFLs represent about a quarter of all U.S. light
bulb shipments.

CHANGE THE WDRIU
ENERGY STAR
2001
An ENERGY STAR specification for residential light fixtures was introduced in
1997, "bringing a benchmark of lighting performance and quality as well as a
clearly recognizable brand to the marketplace."29 The goal was to offer consumers
an efficient lighting option with no sacrifice in performance. The initial focus on
fixtures was also intended to help address issues such as fit and aesthetics, so
the fixture and bulb could be designed in an integrated way.
Working with utilities and other regional energy efficiency programs that hosted
educational and bulb exchange events around the country, the ENERGY STAR
program and its partners achieved early success with torchieres, the tall floor
lamps that direct light upward. Conventional halogen torchieres consumed
300 to 500 watts30 and were a fire hazard31—some events showcased
firemen frying eggs on the heat emitted. Efficient ENERGY STAR qualified
torchieres did not generate significant wasted heat and were much safer.
By September 1999, one million ENERGY STAR qualified torchieres had
been sold.32
That same year, DOE launched a stand-alone ENERGY STAR specification for
CFL bulbs, garnering even greater support from utilities and regional energy
efficiency programs given that bulbs were replaced more frequently than
fixtures. Similar to the fixture criteria, this specification set the first benchmark
for energy efficiency, quality and performance in CFLs and required that all
products be tested by an accredited laboratory.
Over the years and through numerous revisions, the ENERGY STAR lighting
specifications tackled the full range of performance issues. Limits, now
as short as one second, were placed on how long a CFL could take to light
up. Sound rating requirements addressed the hum associated with lighting
ballasts. Light quality was approached from every angle, including how long
it takes the bulb to warm up to full brightness and how many hours of life
before the light starts to dim. Another set of requirements helped to ensure
that an object illuminated by an ENERGY STAR qualified light would appear
the same as it would if it were lit by a standard bulb. Mercury content was
limited. And on top of all that, a minimum two-year warranty was imposed.
Throughout the process, DOE and EPA focused on using strict performance
27
-------
standards, but also on working with industry and stakeholders
to develop entirely new tests when needed. With each revision
to the ENERGY STAR program requirements, the quality of the
products increased and consumer satisfaction went up.
To help ensure that lighting products associated with the ENERGY
STAR label lived up to these many expectations, a group of
utilities, energy efficiency advocates and market transformation
organizations formed the Program for the Evaluation and Analysis
of Residential Lighting (PEARL). They purchased products from
retail stores and tested the performance of ENERGY STAR
qualified lighting products being promoted in their various
service territories. Performance failures were brought to the
attention of EPA and DOE. As a result of this testing, numerous
products were removed from the program and enhancements
were made to the ENERGY STAR lighting requirements.The U.S.
government subsequently initiated its own quality assurance
testing for ENERGY STAR qualified lighting.
Nationally, starting in 2003, the number of CFLs shipped to
retail stores increased to about 50 million per year, and with
that increase manufacturers were able to lower prices. National
retailers also played a role in the success of CFLs when Walmart
pledged to sell 100 million CFLs in 2007. Today, shipments for
CFLs are about 300 million per year; much of the increase in
sales is due to the impact that ENERGY STAR and its partners
have had on product quality and consumer acceptance.
THE 2007
ENERGY STAR
2007
Another important strategy in market transformation was rallying the market
to educate consumers on the substantial benefits of ENERGY STAR qualified
lighting. In the fall of 2001, retailers, utilities and manufacturers united around
the first-ever nationally coordinated lighting promotion: Change a Light,
Change the World. More than 100 utilities and other program sponsors,
hundreds of retailers, and 25 fixture and bulb manufacturers participated in the
promotion, which generated media interest that reached millions of prospective
purchasers throughout the country. This nationally coordinated promotion has
been the cornerstone of ENERGY STAR product outreach ever since, eventually
transitioning to the Change the World, Start with ENERGY STAR campaign in
2008 to include additional ENERGY STAR product categories and promotion of
energy-saving behaviors.

Today, satisfaction with CFLs is no longer a big concern, with national surveys
finding more than 80 percent of consumers "satisfied" or "very satisfied"
with CFL performance.33 Household penetration is also on the rise. In 2009,
68 million households (60 percent) had at least some energy-efficient compact
fluorescent or LED lights.34 Savings from ENERGY STAR qualified CFLs and
fixtures are expected to reach 66 billion kWh per year in 2012, reducing annual
electric bills by $6.4 billion and greenhouse gas emissions by 46 million
metric tons.36
DOE introduced an ENERGY STAR specification for LED bulbs in 2010,
following the earlier pattern of setting high performance criteria. As efficient
lighting choices expand, the ENERGY STAR program remains committed to
quality and to ensuring that products meet consumer expectations. A recent
Consumer Reports article on CFL and LED bulbs found that problems with
earlier versions have been overcome and that today's light bulbs "last longer
and use far less electricity than traditional incandescent bulbs. Shoppers now
have a variety of bulbs to match their needs."36 Consumer Reports also stated
that "ENERGY STAR qualified bulbs meet high standards for brightness, color,
and energy use."37 Their buying advice: choose ENERGY STAR.

GE and ENERGY STAR: A Rich and Beneficial History
Lisa McLeer, Manager of Sales Development and ENERGY STAR Promotions
General Electric
GE Lighting partnered with ENERGY STAR during the development of the
first specification for compact fluorescent light bulbs (CFLs) in 1999, and has
been promoting the benefits of ENERGY STAR qualified lighting products
ever since. Partnering with the ENERGY STAR program was a natural fit
for GE. For many decades, GE has invented and sold high quality energy
efficient lighting. ENERGY STAR'S approach exactly fit this high-quality, high-
performance model, offering stringent specifications for products to meet.
In the late 1990s, CFLs were still relatively large, heavy, costly and blinked
their way on, eventually warming up to full brightness. In addition, there
were many importers—all trying to sell products for lower costs by lowering
product quality.This resulted in many products from unknown manufacturers
that did not perform or last nearly as long as advertised, tarnishing the image
of all CFLs and leading to very slow adoption. Retailers were unsure which
products to sell and utilities were unsure which products to rebate. In the
beginning, utilities funded third-party testing to prove that products did indeed
meet these new specifications—making the program more credible. To try to
eliminate poor-quality products, retailers, as well as utilities providing rebates,
began requiring the ENERGY STAR label on CFLs, greatly improving overall
product quality in the market.
With this new market dynamic, investing in the development of ENERGY STAR
products became a key consideration by GE product teams. GE continues
this strong commitment today with the development of new energy-efficient
LED lighting products that are ENERGY STAR qualified.
The ENERGY STAR program also aligns well with GE's corporate
ecomaginationSM initiative started in 2005. Both brands help customers save
money on energy, taking into consideration the second price tag of energy
costs and other environmental factors. Taking into account both changing
ENERGY STAR specifications and ecomagination, GE engineers have developed
CFLs that now:
• Are smaller, moving to smaller diameter lamp glass using less material,
allowing lamps to fit into more fixtures
• Are longer-lived, increasing lamp life up to 12,000 hours today from 6,000
hours 10 years ago
• Are more efficient with lightweight electronic ballasts
• Start instantly, with no more blinking
• Look like incandescent lamps, with innovative Ship-in-a-Bottle designs
using very small ballasts
• Are available in many shades which are tightly controlled so lamp to lamp
appearance is uniform
• Are available in specialty and decorative sizes
• Are available in dimming and 3-way options
Over the years, ENERGY STAR marketing campaigns have provided impactful
creative platforms for the promotion of energy-efficient products including the
Change the World, Start with ENERGY STAR pledge. This
program has created millions of impressions for GE and
ENERGY STAR. ^^^
GE has a rich and beneficial history with the ENERGY STAR
program. GE plans to continue this partnership, where
everyone wins, especially the environment.

ENERGY STAR Product Retrospective
Televisions
An early ENERGY STAR public service announcement (PSA) shows a family
sitting at home with an overflowing bowl of popcorn, discussing who will turn
on the TV. The husband reluctantly rises from the couch and begins yanking
a starter.
"Don't flood it," instructs his wife, as smoke spews from the TV.
This humorous depiction, dubbed "the lawnmower PSA," drew the important
link between home appliances and the air pollution they cause. The majority
of U.S. electricity is produced by burning fossil fuels, and as a result of energy
use, the average home pollutes more than the average car—a statement that
surprises many people to this day.
Another surprise for consumers is that many home electronics use power
when they appear to be turned off. Research in the late 1990s indicated that
consumers paid an estimated $3 billion annually for this "leaking" electricity,
with $1 billion of the bill created by TVs and VCRs.38 Testing by Lawrence
Berkeley National Laboratory (LBNL) found that energy use in standby mode
varied significantly by model, with TVs using between zero and 12 watts, VCRs
using 2-13 watts and TV/VCR combination units using 3-20 watts. It was clear
that some products delivered services more efficiently, so the capability was
there. It turned out that in many cases the cost of achieving higher efficiencies
could be negligible, but it was not a priority for manufacturers. Consumers
were not willing to pay more for energy efficiency and it was generally viewed
as more profitable to invest design time in improving picture or sound quality.39
Priorities were about to change.
EPA, TV and VCR manufacturers, industry trade associations including the
Electronics Industry Association and the Consumer Electronics Manufacturers
Association40 and other interested stakeholders began working together
to develop and launch an ENERGY STAR specification for TVs and VCRs.
Announced in January 1998 at the Consumer Electronics Show in Las Vegas,
the ENERGY STAR requirements set the bar at three watts in standby mode
for TVs, four watts for VCRs, and six watts for combination units. In mid-2005,
ENERGY STAR specifications were tightened to require a power draw of less
than one watt. By 2008, nearly 80 percent of TVs met these requirements,
reducing overall standby consumption by more than seven billion kWh per
year,41 double the annual energy consumption of Washington, D.C.
Despite this success, major trends were emerging that led advocates such as
the Natural Resources Defense Council (NRDC) to conclude that, left unabated,
TV energy use in the U.S. could increase by 50 percent in five years. These
trends included:
• The number of TVs in operation was growing—shipments were expected
to increase from 29 million in 2005 to nearly 38 million in 2009.42
• Sales of large TVs were on the rise and larger usually meant higher
energy use.
• Sales of TVs that required more energy to operate were on the rise. For
example, display technology was changing as CRTs (cathode ray tubes)
were being replaced by plasma TVs and digital TVs including HDTVs (high-
definition TVs). Digital was replacing analog technology.
• Americans were watching more TV per day due to increased programming
and video game and DVD use.43
2010
During an Earth Day episode of The Ellen Show, 400 audience members received ENERGY STAR qualified televisions from ENERGY STAR partner Best Buy.
31
-------
It was clear that the power needed to operate TVs in active use was a significant
and growing concern. Analysis conducted by NRDC in 2004, based on off-the-shelf
measurements of TV energy consumption, revealed that three key features had a
noticeable impact on energy use: screen area, display technology and resolution
level.44 Power consumption was found to vary as much as 40 percent based on
the type of image a TV is displaying at a given time,46 but the test procedure in the
U.S. for measuring active power consumption had been developed 30 years prior,
for use with black and white, analog TVs.46 Developing a test procedure that would
accommodate new technologies was an essential next step.
EPA began working with the International Electrotechnical Commission (IEC) on a
test procedure that addressed active power consumption and could be used as
the basis for an updated ENERGY STAR specification. IEC developed the draft
international standard in record time and made it available to ENERGY STAR
stakeholders ahead of official publication to aid the specification revision process.47
The standard included a visual test clip for determining average wattage consumed
in a simulated real-world setting, when variable dark and bright images are displayed.
Since that time, the ENERGY STAR criteria for televisions have addressed both
standby and active mode energy consumption, while accommodating consumer
preference for larger screen sizes. Old-fashioned tube televisions have quickly
become a thing of the past, replaced by high definition screens powered with
LCD (liquid crystal display), plasma, OLED (organic light emitting diode) and other
new technologies. The ENERGY STAR specification for TVs has kept pace with
technological advances while raising the bar for efficiency three times in the last
four years alone, ensuring that TVs offer consumers all the viewing pleasure they
seek without exceeding their utility budgets.
Televisions that meet today's ENERGY STAR requirements are, on average, 40
percent more energy efficient than conventional models, saving American viewers
and gamers a total of $3.5 billion per year on their energy bills and preventing

TV sales and sizes have increased dramatically in the U.S. over the past
20 years—40 million are projected to ship in 2012, with an average
screen size of 50 inches. With ENERGY STAR, electricity use forTVs in
the U.S. is 36 billion kWh per year less than it might have been.

Large gains in efficiency have occurred in the television market over the
last few years alone. In 2008, ENERGY STAR qualified large-screen TV
models consumed as much as 500 watts while in active mode. Three years
later, even the largest ENERGY STAR models consume just over 100 watts.

Standby Power
Many appliances and electronic devices that appear to be off are actually in standby mode—not
providing their primary function, but enabling features such as "instant on," digital clock displays,
remote control and preserved user program settings. While each device may consume only a small
amount of energy for these features, the environmental impact and costs really add up when one
considers that the average U.S. household now owns nearly 24 electronic products.48 It is estimated
that standby power accounts for more than 100 billion kWh of annual U.S. electricity consumption and
$11 billion in annual energy costs.49While standby power can deliver a range of worthwhile functions,
it also can be unnecessarily wasteful because of poor product design, including the use of inefficient
components and power supplies.
EPA issued its first energy efficiency specification for standby power in 1998 for televisions, VCRs
and combination units. By 2000, France, the Netherlands, Japan and Australia had identified standby
power as an energy concern; it was clear that standby power was a global issue that would require
multilateral coordination on a test standard, mode definitions and data analysis. The International
Energy Agency (IEA) began promoting international efforts to reduce standby power, relying heavily
on ENERGY STAR measurements and policies.60
EPA worked with representatives from industry and from other countries to develop and later revise
the International Electrotechnical Commission's (IEC) standby test standard, IEC 62301. This test
procedure provides a common technical basis for the formal and accurate determination of standby
power in appliances and equipment around the world. Today, it has been adopted and is in use in
many countries. For example, the Chinese government informally adopted the ENERGY STAR TV
specification, which includes this standard, in 2002, leading to a five watt per unit reduction in standby
power across 40 million TVs.
Standby power is currently addressed for 10 ENERGY STAR product categories, either directly (often
with a not-to-exceed requirement of one watt or less) or as part of a total energy consumption metric
that simultaneously evaluates standby and active power to ensure overall energy efficiency. The
program encourages seamless integration of efficient standby power in ENERGY STAR qualified
products.Technological innovation in this area prevents billions of pounds of greenhouse gas emissions
every year. With the help of ENERGY STAR, electronics manufacturers across the globe have
increased consumer choice while reducing standby power losses in a wide array of residential and
commercial products.

You Really Can Have It All
Noah Horowitz, Senior Scientist, Natural Resources Defense Council
Several years ago, I began to notice these new "thinner'TVs with really crisp
pictures that were popping up everywhere. Places like hotel lobbies, airport
seating areas, health clubs and even my local Japanese restaurant had them,
and many were on all the time. Everyone loved these new "digital" or big
screen TVs. All indications in the press were that sales would continue to
explode, and next year's models would be even bigger.
Given these trends, NRDC conducted the first ever in-depth study on new TV
energy use. What we found was thatTVs were on more hours per day and,
in some cases, were consuming as much electricity as a new refrigerator.
The total amounted to around four percent of all residential electricity use.
These findings led us to discussions with EPA which, in turn, convinced EPA
it was time for ENERGY STAR to address active TV power use in addition to
standby (power consumed by the TV when it is off). A global industry effort
to develop an on-modeTest Method followed and laid the groundwork for
driving down on-mode power use. Now let's fast forward to the massive
improvements that have been achieved since then in terms of TV efficiency.
In 2008, consumers saw ENERGY STAR TVs maximized for efficiency
in on mode for the first time. These new requirements also discouraged
manufacturers from shipping their TVs in "torch mode." Traditionally, TVs
were shipped with overly bright settings to ensure they looked good on the
brightly lit retail floor. Most consumers however failed to go into the menu to
select a more appropriate brightness level for their home, and as a result,TVs
in the U.S. consumed 10 to 20 percent more energy than they needed to.
ENERGY STAR jump-started industry's shift towards improved setup menus
for consumers and away from the brightest possible mode to a mode that is
ideal for home viewing.
Next up was the negotiation to significantly accelerate the deployment
of more efficient TV designs—things like more efficient backlights, more
efficient tuners and power supplies, etc. EPA published a new two-tiered
specification creating immediate savings and a national design target for
manufacturers to achieve in the future—helping reduce the power use of
new TVs by an additional 40-50 percent.
Despite skepticism expressed by industry during the specification setting
process, within one year, well over 50 percent of models met the first tier
requirements. This transformation was due to a combination of factors,
including the availability of financial incentives to retailers by leading utilities
such as Pacific Gas and Electric for selling models that met or exceeded
ENERGY STAR requirements.
In September 2011, the second tier kicked in early, and as a result we now
have 42-inch model TVs on the market that once consumed 400 watts using
under 100 watts. That's a whopping 75 percent reduction in power use,
and to top it off, the efficient TV has all sorts of new features that the old,
inefficient model didn't.
NRDC applauds the EPA and the ENERGY STAR program for helping to
transform the TV market. Due in large part to their efforts, U.S. consumers
are savings billions of dollars a year on their
electric bills, and U.S. emissions of C02, caused by
powering our TVs and other electronics have been
reduced by several million tons annually.

Computer Power Management
Since 1992, ENERGY STAR qualified computers and monitors have had the ability to go into sleep mode,
powering down after a period of inactivity. Unfortunately, as corporations began managing computers
through centralized networks and computer operating systems became more complex, it became
apparent that these features were not being used extensively and, in some cases, were disabled. The
ENERGY STAR promise of saved energy and environmental protection was not being fully realized. In
2001, Lawrence Berkeley National Laboratory estimated that only 56 percent of personal computers
had power management settings on monitors activated.61 Key barriers included lack of understanding
about the importance of power managing office equipment, as well as inconvenience—it was
difficult for network administrators to easily enable sleep
settings across their organizations.
To tackle these challenges, EPA launched the Million
Monitor Drive campaign in 2001, focusing on monitors
because they generally consumed more energy than
computers and because IT managers were more
amenable to power managing them. The campaign
included public events, media outreach and direct
outreach to large, computer-intensive organizations.
The goal was to activate the sleep setting in one million
monitors the first year.The campaign went a step beyond
typical program offerings by providing technological
solutions—a free software tool developed by DOE
called EZ Save that allowed network administrators
to manage power settings from a central server and
companion, web-based software, EZ Wizard, which
allowed individuals to activate monitor power-saving
features in mere seconds.

Offering a set of "Sleep is Good" themed materials to help educate corporate
executives, IT managers and computer users, the ENERGY STAR Million
Monitor Drive gathered pledges to change from a wide range of organizations:
large corporations such as Ford Motor Company, General Motors, General
Electric, Wells Fargo, Citigroup and Boeing; schools and universities including
Fairfax County public schools in Virginia, New York City Department of
Education and Harvard University; and more than 50 state, county and
municipal governments across the nation. Less than four years later, 6.4 million
monitors had been power managed, saving an estimated 660 million kWh, and
significantly exceeding campaign goals.
In 2008, this effort evolved into the Low Carbon IT campaign, with a focus
on computer power management and other IT equipment. The ENERGY

Perhaps not the making of an Academy Award-winning screenplay, but
the scenario—all too familiar to the efficiency community—demonstrates
that there are often split incentives to greater efficiency. In this case, the
star athlete has no reason to think twice about the vending machine she
used to purchase her soda, the machine owner is not responsible for
paying the utility bill and therefore has little reason to be concerned about
its efficiency, and the school administrator who does pay the electric bill
has no way of linking energy use to the vending machine.
Behind the scenes, EPA, DOE and efficiency advocates were working to
identify strategies to revise the script. An energy-efficient vending machine
working group, consisting of representatives from the Natural Resources
2009
ENERGY STAR made David Letterman'sTop 10 list on The Late Show.
-------
Defense Council, EPA, DOE and its national laboratories, the American Council
for an Energy-Efficient Economy, the California Energy Commission and the
Consortium for Energy Efficiency, was formed with the goal of forging a path
to transform the efficiency of refrigerated vending machines.64 Fortunately,
several important foundational elements were already in place:
• The Canadian Standards Association (CSA) had established measurement
procedures and voluntary maximum daily energy consumption levels for
beverage vending machines.
• The American Society of Heating, Refrigeration and Air Conditioning
(ASHRAE) had developed a related test procedure that would allow for
comparison of energy performance (though the results were not published
in one place or readily available to end users).
• There appeared to be several cost-effective ways for manufacturers to
improve the efficiency of their machines. Those changes might appeal to
end users if they were aware of operational cost savings, though it was
believed that distributors would balk at any improvement that added even
minimally to machine costs.66
At the time the working group was formed, lighting, which is important in
vending for attracting potential customers, represented about 30-40 percent
of the total energy use. Machines were frequently illuminated all day and night,
even when no one was around to see the machine or purchase a beverage.
More efficient fluorescent lighting was available but not produced in an
optimal size for vending machines, partially due to lack of demand. A number
of low-cost technologies, such as timers and motion detectors, could be
used to turn off lights when they were not needed. Energy waste associated
with refrigeration could be addressed using more efficient evaporator and
condenser fan motors, compressors and insulation.66
As these various options were considered, it turned out there were some non-
energy benefits associated with improved lighting technology that appealed
to distributors—the efficient lighting would last longer, reducing the need
for service calls. What's more, brand new machines represented only a slice
of the market and the energy efficiency potential. While machines typically
lasted 10 years or more, they were often shipped to refurbishment centers
for an overhaul within three to four years.67 As a result, new machines were
built with modular components and were good candidates for upgrades with
efficient components.
EPA officially launched the ENERGY STAR label for refrigerated beverage
vending machines at the National Automatic Merchandising Association Spring
Expo in April 2004. The specification ensured that ENERGY STAR qualified
new machines would be 35 percent more efficient than machines that were
commonly available at the time,68 and would deliver additional savings (50
percent more efficient than commonly available) in less than three years. Once
the details were worked out, rebuilt machines became eligible for ENERGY
STAR qualification in August 2006.
When the ENERGY STAR specification was first launched, typical refrigerated
vending machines were using as much as 13-15 kWh per day—or about five
times the amount of a typical household refrigerator—and those paying the
energy bills had no way to easily identify and request more efficient machines
in their vending contracts. The ENERGY STAR designation enabled them
to say, "we care about the environment and our electric bill and only want
ENERGY STAR qualified models installed on our property." In just a few years,
vending-machine manufacturers were introducing ENERGY STAR qualified
models that reduced energy consumption by more than 50 percent. Today,
ENERGY STAR qualified vending machines use only 3-7 kWh per day,69 and
commitments by major end users such as Pepsi and Coke to upgrade existing
machines quickly, have brought the installed base to more than one million
ENERGY STAR qualified machines.60
In August 2012, federal minimum efficiency standards take effect for new
refrigerated beverage machines, locking in savings of approximately $150
annually for each vending machine. When all vending machines are performing
at this standard, the current ENERGY STAR level, the savings will exceed
5.5 billion kWh per year, preventing four million metric tons of greenhouse
gas emissions.

ENERGY STAR Product Retrospective
External Power Supplies
On the path to our homes from the power plant, electricity travels across
transmission lines as high-voltage alternating current (AC), which is then
reduced by our utility distribution company until it magically emerges from
the wall socket as 120/240 volts AC, capable of powering any device with a
standard two- or three-pronged plug. But some electronics and battery-charged
tools require a much lower AC or finely regulated direct current (DC) to operate;
you can tell which these are by the power adapter or external power supply
(EPS) at the end of the cord. There are more than three billion EPSs in use in
the U.S. today.
One of the reasons EPSs are so popular is that they allow end-use product
manufacturers to save time and money on Underwriter Laboratories (UL)
safety listings, since the voltage reduction and AC-DC power conversion occurs
outside the end-use product. External conversions allow for modular designs,
and modular designs mean a commoditized market. About 900 million EPSs are
shipped annually61 for domestic use, with thousands of manufacturers worldwide
competing for customers, often by offering the lowest price.
For years, these EPSs were known as "energy vampires."They performed their
function very inefficiently, sucking energy unnecessarily when the products
for which they were intended were turned off, already fully charged, or even
removed from the EPS. Much of the power entering the EPS was lost as
wasted heat, with only a portion of it going to operate or charge the product.
In 2002, typical energy efficiencies ranged from 15-80 percent when devices
were in active use; energy losses when products were plugged in but not in
use ranged from less than one watt to about four watts.62
Given the great variability in energy consumption for EPSs, it was obvious
that there were more efficient ways to convert energy. However, the most
efficient technologies were typically reserved for high-end, higher wattage
products or portable devices. The majority of power supply products,
particularly those using 20 watts or less, were on the low end of
the performance spectrum. End-use manufacturers, who
often compete on high volume with low profit margins,
were concerned about costs. Cost premiums for
more efficient EPSs ranged from a potential 10-30
percent, and changing to a different EPS could
trigger design changes and delay production.
What is more, efficiency or lack thereof was
invisible to both the end-use manufacturer and the
ultimate consumer—EPSs were labeled only for the
maximum power draw and maximum current they could
provide at a given voltage.^Therefore, energy-efficient EPSs
might be difficult to market.
Recognizing the global nature of both supply and demand of EPSs,
EPA began working with stakeholders in the U.S., China, Europe, Canada
and Australia to explore ways to encourage improved efficiency. In addition to
needing a standard test method for measuring AC-DC power supply efficiency,
which the California Energy Commission was instrumental in developing,65
manufacturers would need an easy way to specify and identify power supply
efficiency in the wide variety of markets in which they operated. Stakeholders
worked together to devise a marking protocol that could be used around the

-------
world by any country interested in EPS efficiency, and provide an easy to understand
system for power supply manufacturers, finished product manufacturers and
government agencies.
The International Efficiency Marking Protocol, which was designed to be printed
on the power supply nameplate, designated the minimum performance of an
EPS using Roman numerals I through VII, with I being the least efficient and VII
being the most efficient—with higher numerals reserved for future, more efficient
products. The marking protocol became a key element of the ENERGY STAR
EPS specification.
Launched at the International Consumer Electronics Show in January 2005 and
at the Applied Power Electronics Conference and Exposition in March 2005, the
ENERGY STAR EPS specification was a cost-effective way to address energy
waste across the broad range of products powered by EPSs but not otherwise
covered by the ENERGY STAR program.66 While the traditional ENERGY
STAR label would not appear on the product, end-use product
manufacturers were encouraged to use a version of it, indicating
that their product was "powered by an ENERGY STAR qualified
adaptor for a better environment" as a way to differentiate their
products in the marketplace.
By 2008, the market share for ENERGY STAR qualified EPSs
had reached an estimated 50 percent, delivering savings
of five billion kWh per year and annual greenhouse gas
reductions of one million metric tons. That same year, a minimum
efficiency standard went into effect in the U.S. mandating the ENERGY
STAR performance level, and a more stringent ENERGY STAR specification
was introduced.67
Today, energy use associated with EPSs nationally is estimated to be 70 billion kWh
per year less than it would have been had EPS energy performance stayed where
it was in 2005—a savings equivalent to the greenhouse gas emissions of more
than nine million vehicles.68 EPA officially retired the ENERGY STAR specification
for EPSs on December 31, 2010, but continues to advance power supply efficiency
through a growing list of ENERGY STAR products that require highly efficient EPSs
as a part of broader energy performance requirements.69

ENERGY STAR Product Retrospective
Digital-to-Analog Converter Boxes
Before 2008, few of us knew what a digital-to-analog converter box (DTA) was.
For Americans who had cable or satellite services or newer televisions with
built-in digital tuners, there was little reason to find out. But the estimated 16
to 22 million Americans who did not subscribe to cable, who owned an older,
analog TV, and who could not afford or did not want to buy a new one would
have to install a DTA before June 2009—when the United States converted to
all-digital broadcasting—in order to stay connected to programming.70
A new DTA was projected to cost about $50 to $60. To ease the transition,
Congress stepped in to make $40 rebates available through the National
Telecommunications and Information Administration (NTIA). But, unless energy
use for these new devices was taken into consideration, those who were most
likely to need DTAs would be least able to afford increased utility bills.
Fortunately for these consumers, EPA had already initiated a stakeholder
process to develop an ENERGY STAR specification for DTAs. These products
were virtually unknown and unavailable in the U.S. market. So EPA invited
potential DTA manufacturers and resellers, component providers and other
interested parties to discuss state-of-the art options for digital chips that could
perform key DTA functions more efficiently than what was then available in the
worldwide marketplace. Domestically, California had established an ambitious
state efficiency standard for DTAs that was being challenged.71 Some industry
experts had estimated that a product capable of meeting such strict efficiency
standards would cost the consumer more than twice the amount anticipated for
a conventional DTA.72 Lack of anticipated demand, small production quantities
and a limited production cycle also were cited as likely contributors to the higher
price tag. If EPA and stakeholders could coalesce around an ENERGY STAR
specification, then market demand and support for efficient DTAs nationally
could help increase production and drive down the purchase price for a more
efficient option. What they needed to agree on were operational definitions such
as "on," "off" and "standby" modes, a standardized procedure for testing power
consumption in each mode and criteria that would set aggressive efficiency
targets, offer the same or better performance as conventional options and
ultimately be cost-effective for consumers.
EPA and its stakeholders concluded the development process in record time,
agreeing on a specification effective January 31, 2007. The specification required
DTAs to automatically power down after extended periods of inactivity. It
set efficiency criteria of less than eight watts in "on" mode and less than
one watt in "sleep" mode—cutting the energy use of DTAs by more than 70
percent compared to products available in the worldwide marketplace.73 When
NTIA released its final rule launching the DTA Coupon Program, they included
requirements that DTAs "comply with standards established by the EPA ENERGY
STAR program or state regulatory authorities."74
Eight manufacturers produced more than 40 different DTA models, selling an
estimated 14.2 million ENERGY STAR qualified DTAs.76 As a result, Americans
are saving about two billion kWh of energy and avoiding about $250 million in
energy costs over the life of these products.76
2011
The 160 million set-top boxes installed in the U.S. consumed enough electricity to power all the homes in the state of Maryland.77 When every set-top box meets ENERGY
STAR requirements, Americans will save about $1.8 billion per year and prevent greenhouse gas emissions equivalent to those of 2.3 million cars.78

ENERGY STAR as a Market Transformation Strategy
Steven Nadel, Executive Director, American Council
for an Energy-Efficient Economy
I remember when I first heard about ENERGY STAR. It was in the early 1990s,
and I was on a plane with then EPA Branch Chief Cathy Zoi, who told me
about an idea they were kicking around. It involved putting labels on personal
computers that had power management features, and they were thinking
of calling it ENERGY STAR. This concept soon moved forward, starting with
personal computers. Manufacturers embraced the concept and soon more
than 90 percent of personal computers had power management features—
an amazingly quick transformation of the market. Since then the ENERGY
STAR specification for personal computers has been revised multiple times.
Each time, manufacturers have responded by redesigning the majority of
their products to meet the ENERGY STAR requirements. As a result, the
typical personal computer and monitor now use about 230 kWh per year,
about half of what they would have consumed had no changes in efficiency
occurred, even though today's machines are much more powerful than
those from the early 1990s.
ENERGY STAR has similarly transformed many other markets. When flat-
screen televisions first reached the market, most were "energy hogs"
and many used more than 600 kWh of energy per year—more than a new
refrigerator. But the ENERGY STAR specification set limits on energy use
and has been progressively tightened.Today, a typical 42-inch ENERGY STAR
qualified flat-screen TV is down to 150 kWh per year. Likewise, ENERGY
STAR has helped transform the market for residential windows. When the
program for windows began with DOE in 1998, most new windows did
not insulate well or block excess heat during the summer. ENERGY STAR
window performance requirements have resulted in better performance and
greater comfort for residents. And to provide just one more example: for
many home appliances, manufacturers design products to meet ENERGY
STAR specifications, and due to consumer interest in ENERGY STAR, these
products steadily grow in market share. As market share increases and
prices decline, what were once ENERGY STAR levels can be used as the
basis of minimum energy efficiency standards, and ENERGY STAR can be
reset for even higher levels of efficiency. As a result, clothes washers and
refrigerators today typically use half the energy that units from the early
1990s did.
Given this track record over the past 20 years, ENERGY STAR is well poised
to continue transforming markets in the decades to come.

The Future of ENERGY STAR
Certified Products
Big Strides, But More Products Mean More Opportunity for Savings
What a different world we find ourselves in 20 years later. In that span of time, we have seen
the energy use of so many devices cut in half, or even better. But even as energy efficiency
has improved substantially, home energy demand continues to climb nationally. This increase in
consumption can be tied in part to the growing number of energy-using products that we all
enjoy. Just think of the many devices you have at your disposal and what they can do for you—
communicating, computing, displaying, life organizing, as well as juicing, frothing, and fresh-bread
producing. Even the tried-and-true classroom blackboard is now electronic and connected to the
Internet. By 2020, miscellaneous products—all these new gadgets—will account for about 30
percent of electricity use in U.S. households.79 And that means that there is plenty more for the
ENERGY STAR program and partners still to accomplish.
Sleep is Still Good, But Products Need to Put Themselves to Bed
Energy efficiency in the future is all about making savings an automatic feature of rapidly evolving,
sophisticated new technologies. ENERGY STAR certified products will increasingly behave
intuitively when it comes to power management. Rather than relying on users to turn off a growing
number of products and all of their accessories, these products will aggressively use power
management to preserve battery life or drastically reduce electricity draw when not in use, and
then wake promptly when called to action. Transfer of well-tested functionality to products not
traditionally known for power management will remain a cornerstone of the program.
By the same token, as more and more products offer networked functionality—displays, TVs, and
even appliances now, not just computers—there is no reason for these products to stay on all
the time to receive network information. The ENERGY STAR program can play an important role,
leveraging recently published standards, to ensure that more and more products drop off to sleep
and then wake seamlessly in response to a network call. Being tethered to the network also has
the promise of furthering intuitive behavior for products. Sensors are beginning to power products
down automatically when there is no one in the room, and home energy management systems
are poised to maximize energy savings when no one is home. Going forward, the ENERGY STAR
program will remain a champion for this kind of energy-saving functionality in products.
-------
Squeezing Out Every Last Drop
After 20 years, delivering additional savings from the existing
suite of ENERGY STAR products raises opportunities and
challenges the program is poised to tackle. A dishwasher
sold today will use about half as much energy as the average
dishwasher sold 20 years ago,80 but it still needs to clean the
dishes. TVs that use very little energy must always deliver
vibrant images. With high-quality performance as a priority,
and thanks to a remarkable tradition of innovation on the
part of manufacturers, there are advances yet to be made
and more energy savings to deliver.
Sometimes new approaches will be needed. Heating
and cooling, for example, still represent nearly half of
home energy costs despite significant progress in energy
efficiency. Getting more out of this category may require
setting regional, climate-based efficiency requirements to
ensure that the biggest savings are targeted for areas with
the best return on investment. Diagnostics, communication
features and improved user interfaces will be increasingly
important to enable consumers to maximize savings.
Products such as programmable thermostats can deliver
enormous consumer and environmental savings—if used
properly. Usability standards, like the one EPA is developing
for residential climate controls, could turn out to be an
important testing ground for improving the usability of a
broad range of energy-saving products.

The Reliable Source for Energy Savings Information
For many Americans, looking for the cyan star will continue to be the simple
way to save energy, save money and help prevent climate change. For others,
the ENERGY STAR program is increasingly the source of credible advice and
information for reducing energy consumption in their homes and businesses.
Consumers and companies trying to navigate increasingly complex purchase
decisions—from buying a light bulb to specifying a data center server—can
count on ENERGY STAR to give them access to information in an easy-to-
use format. And for those who are ready to take the next step, the program
offers an ever-expanding collection of energy-saving behaviors, advice and
tools developed using the same rigor applied to defining product efficiency.
Encouraging the development of products that use less while doing more,
that are more and more intuitive and usable, along with fostering an action-
oriented ethos around saving energy, are investments that will continue to
pay off for Americans and the environment. The ENERGY STAR program
remains up to the task.
