This act created the Department of Energy. It began its operations on October 1, 1977, and combined major federal energy functions such as the Federal Energy Administration and the Energy Research and Development Administration into one agency. The Department of Energy was created to resolve the energy crisis at that time. Efforts to conserve energy and develop alternative energy sources have been the main focus of the department in recent years. ## **Functions of the United States Department of Energy** Some of the responsibilities of the Department of Energy include the following: ### **Developing Energy Sources** The department is responsible for the development of sustainable and low-cost energy supplies.
