The Environmental Protection Agency recognized the Air Force in its top 25 list of 2010 green power partners. USAF purchased or produced a total of 243.9 million kilowatt-hours of green power last year, according to the list, which came out last month. That makes the Air Force No. 1 in the Defense Department, No. 2 in the federal government, and No. 15 among EPA’s 1,300 green power partners for its use of renewable energy. More than six percent of all energy that Air Force facilities consume comes from green power, but that number is expected to spike to 10 percent by 2015. “This year we expect to begin construction on at least a dozen more renewable energy projects, including two new solar arrays in Arizona,” said Ken Gray, Air Force Facility Energy Center rates and renewables branch chief at Tyndall AFB, Fla.

The Space Force is playing midwife to a new ecosystem of commercial satellite constellations providing alternatives to the service’s own Global Positioning Service from much closer to the Earth, making their signals more accurate and harder to jam.
