More power on less oil
The U.S. military is about as far from green as you can get. It's a massive organization with a carbon footprint that rivals many large nations. The military has hundreds of thousands of vehicles, ships, planes, tanks and submarines that burn through enough fuel to make it the largest buyer of petroleum products in the world. Its environmental record has been grim, but even the military recognizes that times are changing and that cheap oil may not always be available.
Change doesn't come quickly in the military (or in most large, established institutions), but a few mavericks inside are pushing greener practices. Whether they think it's the right thing to do or they're being pragmatic in the face of uncertain oil markets, the results are small steps toward a greener military. Here are six things that the U.S. military is doing to prepare for a future without cheap oil. (Text: Shea Gunther)
