US-Army-in-IraqEven if I knew thanks to Thomas Friedman and his book Hot, Flat and Crowded that the US Army is willing to outgreen its opponents, I found more information in an article from the New York Times.

Here are a few ideas it is putting in place: energy saving by insulating tents, low carbon energy from waste, recycling water and alternatives fuel made of algae for jets.
