The Department of Energy's (DOE) overarching mission is to advance the national, economic, and energy security of the United States; to promote scientific and technological innovation in support of that mission; and to ensure the environmental cleanup of the national nuclear weapons complex. Laws passed by Congress and signed by the President both define DOE’s authorities and set forth DOE’s responsibilities. Additionally, a number of Executive Orders issued by the President play a central role in guiding DOE’s activities.

In the space below, we have provided links to key statutes and executive orders which affect the Department of Energy. For most laws, we provide a link to the United States Code (U.S.C.), which is the codification by subject matter of the general and permanent laws of the United States. In some instances, we provide a link to a PDF version of a law because it is sometimes difficult to read the full text in the U.S.C. These resources are categorized in alphabetical order. Please note that this site is intended solely as an educational resource for the public and does not purport to be an exhaustive list.
