The U.S. Military is deeply committed to developing renewable energy technologies and minimizing climate change impacts. Does that surprise you? The reason is that the military’s top leaders see climate change impacts and energy availability as keys to keeping our soldiers, our citizens and the people of the world safe. For instance, every gallon of fuel that can be replaced by solar power or high-storage batteries is one less gallon of fuel that has to be bought and transported. Secretary of Defense Chuck Hagel reaffirmed this commitment recently at a security conference. Here’s why that’s cool. Remember how the Internet originally started out as a military project? In the same way, it’s a sure bet that the renewable energy innovations that come out of the military’s sustainability programs will inform our lives, too.
