The U.S. Air Force leads the nation in green power purchasing, recently announcing collective purchases in excess of 1 billion kWh annually. This more than triples the 320 million kWh that the Air Force purchased in fiscal year 2004, which at the time represented 41% of all green power purchased by the federal government.
Most of the green power purchased by the Air Force comes from wind energy, but its portfolio also includes the use of biomass energy at Hill AFB in Utah, and more than 3,500 ground source heat pumps at various installations. In addition, the Air Force generates its own power by operating a 2.4-MW wind farm on Ascension Island and a 1.3-MW wind farm at F.E. Warren AFB in Wyoming. At least two bases—Dyess AFB in Texas and Fairchild AFB in Washington—purchase green power for 100% of their electricity needs.
