Hydroelectric facility

A hydroelectric facility is a special type of power plant that uses the energy of falling or flowing water to generate electricity.They do this by directing water over a series of turbines which convert the potential and kinetic energy of water into the rotational motion of the turbine. The turbine is then attached to a generator and the motion is used to generate electricity.

Hydroelectric Energy

Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia. Over 2,000 years ago, people in Greece used flowing water to turn the wheel of their mill to ground wheat into flour.
