     Quick Facts on State Solar Energy Policy as of December 2009
     A state renewable portfolio standard (RPS) that includes a solar set-aside requires a percentage of the
     state's electricity be generated from solar resources. An RPS can also include a solar multiplier that gives
     additional credit in meeting the RPS for solar projects or require an increase in distributed generation (i.e.,
     electricity generation close to the point of use), which can spur solar development. Policy driven demand
     for electricity generated from solar resources may increase the viability of PV solar generation at a site
     that would other/vise not be considered viable based on solar resource availability.

                      OSWER Center for Program Analysis. Results are based on site screening criteria adapted from
                      National Renev&ble Energy Laboratory (NREL) criteria. GIS data provided by NREL and EPA and policy
                      data provided by the Database of State Incentives for Renev&bles & Efficiency (DSIRE). This map and
                      its associated data are intended to provide a general understanding of the renevjable energy potential of
                      EPA tracked sites: additional site-specific technical and economic analysis is required to
                      determine the actual energy generation potential of these sites. For further information, please see
