How Hydropower Works - Department of Energy
WEBHydropower, or hydroelectric power, is a renewable source of energy that generates power by using a dam or diversion structure to alter the natural flow of a river or other body of water.
Hydroelectric power | Definition, Renewable Energy, Advantages ...
WEBHydroelectric power is a form of renewable energy in which electricity is produced from generators driven by turbines that convert the potential energy of moving water into mechanical energy. Hydroelectric power plants usually are located in dams that impound rivers, though tidal action is used in some coastal areas.
