According to an October 26 study by RAND Arroyo Center, the U.S. Army can reduce its energy consumption and meet other energy goals by entering into service contracts with utility companies and collaborating with utilities on renewable energy projects. The Making the Connection: Beneficial Collaboration Between Army Installations and Energy Utility Companies also suggests that the Army can reduce energy use and costs by educating personnel about contracts and energy projects. The Army is required to reduce its energy consumption 30 percent by 2015 under the Energy Independence and Security Act of 207 and increase its use of renewable energy by 7.5 percent by 2013 under the Energy Policy Act of 2005.
