| Description: | Although the U.S. Department of Energy's institutional origins began the atomic century, there has been an increased emphasis on environmental activities and technology innovation since the agency was activated in 1977. The Department of Energy's mission is to foster a secure and reliable energy system that is environmentally and economically sustainable, to be a responsible steward of the Nation's nuclear weapons, to clean up our own facilities and to support continued United States leadership in science and technology. |
