Through its Office of Planning, Budget and Analysis, the U.S. DOE Energy Efficiency and Renewable Energy (EERE) provides estimates of program benefits in its annual Congressional Budget Request. The Government Performance and Results Act (GPRA) of 1993 provides the basis for assessing the performance of Federally funded programs. Often referred to as "GPRA Benefits Estimates," these estimates represent one piece of EERE's GPRA implementation efforts—documenting some of the economic, environmental, and security benefits (or outcomes) from achieving program goals.
