The Army is researching hybrid and fuel cells for vehicles as well as better battery systems. They understand that energy security means creating your own energy.
The Army is well aware of its potential for pulling the entire civilian market into a more sustainable future in which oil and other fossil fuels follow national defense goals rather than leading them.
A few decades back DARPA created a little thing called the Internet. Hopefully the research they are doing now will create clean energy technologies of the same magnitude as the Internet.
