"The Department of Energy (DOE) is responsible for advancing the energy, environmental, and nuclear security of the United States; promoting scientific and technological innovation in support of that mission; sponsoring basic research in the physical sciences; and ensuring the environmental cleanup of  the nation’s nuclear weapons complex. The DOE enterprise has 64 sites across 29 states and the District of Columbia, including 17 National Laboratories that form a critical part of America’s research enterprise. During the eight years of the Obama Administration, DOE has delivered on its mission. The results have included dramatic growth in clean energy jobs, vital progress on securing and diminishing the amount of nuclear material globally, and major scientific and technological (S&T) discoveries."
