Mission 

The mission of the Energy Department is to ensure America’s security and prosperity by addressing its energy, environmental and nuclear challenges through transformative science and technology solutions.

Leadership

As United States Secretary of Energy, Rick Perry leads an agency tasked with maintaining a safe, secure and effective nuclear deterrent and reducing the threat of nuclear proliferation, overseeing the United States’ energy supply, carrying out the environmental clean-up from the Cold War nuclear mission, and the 17 National Laboratories

History

The Department of Energy 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.
