We've written about Corporate America seizing the reins of the green-energy movement, but Big Business is hardly alone. The military is moving full-speed ahead in an effort to rely less on costly foreign oil and more on renewables, while also saving money through energy conservation.

It really is fascinating to watch. The military no longer wants to be the biggest consumer of fossil fuel in the world. So, ships are heading to sea with hybrid technology that could save billions in fuel costs, soldiers in war zones are using solar energy, the Army has a goal of net-zero energy use and the U.S. Air Force has concluded that saving energy not only saves the environment, but could save lives and money.

The Department of Defense has even established a Web site that details its Green efforts.

Navy Secretary Ray Mabus said at a recent clean-energy conference (where he also criticized a RAND Corp. study that questioned the effectiveness of biofuels) that a green fleet makes sense considering the massive costs in dollars and lives of using and hauling oil, and the apparent disconnect of using foreign sources to power ships, planes and tanks that are made in the United States.

How strong the green-energy movement gets in this era of budget cuts and political bickering remains to be seen, but the support of Big Business and the Department of Defense helps keep up the momentum.
