Clean energy is important because it has the power to enhance economic growth, support energy independence, and improve the health and well-being of the American people. The U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) is committed to leading the nation’s transition to a clean energy economy for these reasons.
energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature.
Energy is essential for every one of us. Humans have advanced because we have learned how to change energy from one form into another.
