During last week’s GreenGov Symposium, the Department of Defense announced efforts to drive innovation in the energy-efficiency sector by being the first customer of as many technologies as possible for its 5,000 installations, and 300,000 buildings, worldwide. The agency also announced an expansion in its use of renewable energy, unveiling both a Defense Intelligence Agency plan to install 160 solar parking lot lights by 2015 and a planned assessment of 14 landfills for methane gas potential.
