August 2005 - The Energy Policy Act of 2005, signed into law by President Bush on August 8, calls for the Secretary of Energy to "ensure that, to the extent economically feasible and technically practicable," 3% of the electric energy consumed by the federal government in fiscal years 2007 through 2009 be derived from renewable sources, increasing to 5% in fiscal years 2010 through 2012, and 7.5% by 2013 and each fiscal year thereafter.
Renewable energy is defined as "electric energy generated from solar, wind, biomass, landfill gas, ocean (including tidal, wave, current, and thermal), geothermal, municipal solid waste, or new hydroelectric generation capacity achieved from increased efficiency or additions of new capacity at an existing hydroelectric project."
The new law replaces Executive Order 13123, issued in 1999, which established a goal for federal agencies to obtain 2.5% of their electricity from renewable energy sources by 2005. Recently, the Federal Energy Management Program issued guidance to federal agencies on purchasing renewable energy.
