The Information Technology & Innovation Foundation released a report October 16 finding that $5 billion in Department of Defense clean energy spending since 2009 could be critical to accelerating the national commercial scale deployment of new energy technologies. The study, Lean, Mean, and Clean II: Assessing DOD Investments in Clean Energy Innovation, concluded that the agency’s investment in advanced alternative fuels, power electronics, and energy storage could have the highest chance of advancing commercialization outside of the military.
