A close-up view of one of the Air Force's two new wind turbines at the Massachusetts Military Reservation in Cape Cod, Mass. 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. They will also offset emissions generated by fossil-fueled power plants, reducing the Air Force's carbon footprint.
