The U.S. military services are turning their attention to energy practices and energy sources as a matter of national defense and security. As debates rage over oil costs and usage as well as the question of when peak oil—the highest rate at which oil can be pumped from the Earth—will be achieved, the service branches are examining ways to use fuel more wisely and exploring alternative energy sources. While experts disagree on many energy issues, most agree that the United States needs to develop renewable and sustainable energy options now to prepare for the future, and the military must take a lead role in that paradigm shift.
The U.S. Defense Department has an energy conservation and development program that is as far and wide as the U.S. military's reach around the world. The department is revamping methodologies and exploring new technologies both to reduce its energy consumption and to ensure a reliable supply in an uncertain global energy environment.
