The U.S. Department of Defense (DoD) is the nation’s largest energy user. In recent years, DoD has launched several initiatives to reduce its fossil fuel use by improving energy efficiency (i.e., reducing wasted energy) and shifting to renewable energy such as biomass, hydropower, geothermal, wind, and solar to meet operational and installation needs. Energy efficiency and renewable energy can benefit mission effectiveness, the environment, and the bottom line, as outlined in the following excerpt from a 2010 Memorandum of Understanding between DoD and the Department of Energy (DOE):
Energy efficiency can serve as a force multiplier, increasing the range and endurance of forces in the field while reducing the number of combat forces diverted to protect energy supply lines, as well as reducing long-term energy costs. DoD is also increasing its use of renewable energy supplies and reducing energy demand to improve energy security and operational effectiveness, reduce greenhouse gas (GHG) emissions in support of U.S. climate change initiatives, and protect the DoD from energy price fluctuations. Solving military challenges through innovation has the potential to yield spin-off technologies that benefit the civilian community as well.
This fact sheet outlines major energy efficiency and renewable energy initiatives underway by the Department of Defense, Army, Navy, Marine Corps, and Air Force. It also provides some examples of U.S. military installations with energy efficiency and renewable energy projects.
