Alternative Energy and Propulsion Power for Today's U.S. Military

The U.S. military has the most sophisticated weapons systems in the world, but they are fueled and mechanically powered by old technologies. Given the mission of the U.S. military, it is without question the largest oil-using organization of its kind in the world. More than half of the Department of Defense's (DoD's) fuel budget is spent on fueling the U.S. Air Force. The Navy consumes about one-third of defense oil resources, and the Army uses about 12%. Twenty-five percent of military energy is used to power and heat buildings and facilities. The remaining 75% is consumed for mobility purposes.
