The Air Force voluntarily bought 457,500 megawatt-hours of “green power” last year, thereby winning the service placement at the head of the Environmental Protection Agency’s list of Top 10 federal government green power purchasers in the Green Power Partnership. All those hours represent more than four percent of the service’s annual electricity usage. Thirty-seven Air Force bases participated in a renewable power purchase program in fiscal year 2006, including three that purchased 100 percent of their electricity from renewable sources. The Air Force has made the top green list for three years running.
The Air Force is leaning toward a less-sophisticated autonomous aircraft in the second increment of the Collaborative Combat Aircraft, the services chief futurist said. He also suggested that the next increment of CCA may be air-launched, a la the "Rapid Dragon" experiments conducted by the service in recent years.
