Holy crap, did you know that your average U.S. soldier in Iraq uses 88 AA bateries during a five day mission!?! The U.S. Military blows through 2.4 million gallons of fuel every day in Iraq and Afghanistan and 2/3 of the stuff soldiers carry in combat is fuel.
All political issues aside, that is a terribly inefficient way to run an army. The military needs to get way more aggressive about embracing renewable energy. Soldiers, missions, and equipment would be more flexible; you would eliminate the need for a lot of convoy driving, which would save lives, equipment, and money; and a whole lotta pollution would be kept from the air.
I’m pragmatic about the world we live in and see the need for our nation to have a strong and kickass military. I have major problems with how it’s been abused by the Bush administration, but that aside- the U.S. Military has gotta be badass.
So why not do it in a way that is smart. Dump a ton of military R&D funds into advancing solar, wind, and thermal energy generation technology. Get advanced solar panels on top of every vehicle, develop panels that can be sewn into uniforms, and build single unit small scale energy power stations that use wind and solar. Consumers will feel the technology overflow love and the whole effort to green up this world will be that much further along.
