New wind turbines help Air Force go green
The Air Force's two new wind turbines at the Massachusetts Military Reservation in Cape Cod, Mass., seen from a distance, pose an interesting contrast to an ornamental traditional windmill atop a local Cape Cod shop. The 1.5 megawatt wind turbines, in addition to an existing turbine, were built to offset electrical costs for powering numerous groundwater cleanup systems at the reservation. The turbines will pay for all the Air Force's electric needs for groundwater remediation at MMR, saving more than $1.5 million per year. (U.S. Air Force photo/Scott Dehainaut)
