Established in 2010, the Office of the Assistant Secretary of Defense for Operational Energy was created to strengthen the energy security of U.S. military operations. The mission of the office is to help the military services and combatant commands improve military capabilities, cut costs, and lower operational and strategic risk through better energy accounting, planning, management, and innovation. Operational energy, or the energy required to train, move, and sustain forces, weapons, and equipment for military operations, accounted for 75 percent of all energy used by the Department of Defense in 2009.
"SERDP and ESTCP’s Energy and Water program area supports the demonstration of innovative technologies to reduce DoD’s installation energy consumption and carbon footprint, improve energy security, and facilitate water conservation."
"Jointly managed on behalf of the Office of the Deputy Under Secretary of Defense (Installations and Environment)...SERDP and ESTCP are the Department of Defense's environmental research programs, harnessing the latest science and technology to improve DoD’s environmental performance, reduce costs, and enhance and sustain mission capabilities. The Programs respond to environmental technology requirements that are common to all of the military Services, complementing the Services’ research programs. SERDP and ESTCP promote partnerships and collaboration among academia, industry, the military Services, and other Federal agencies."
