Photo of Photovoltaic System at the Forrestal Building in Washington, DCThe U.S. Department of Energy (DOE) is housed in the Forrestal Building in Washington, DC. A photovoltaic (PV) system was installed as part of the DOE's support of alternative energy and the Federal initiatives to lower energy usage. The 3 kW AC PV system is mounted on a balcony on the south side of the building. It contributes to lower the energy use in the building and works in conjunction with other measures such as energy-saving lighting fixtures and a system that turns off all lights when the staff is not present.
