The U.S. Department of Energy (DOE) has one of the richest and most diverse histories in the federal government. Although only in existence since 1977, the Department traces its lineage to the Manhattan Project effort to develop the atomic bomb during World War II and to the various energy-related programs that previously had been dispersed throughout various federal agencies.
