Hydroelectric Energy

Hydroelectric energy is also known as hydropower or hydroelectricity. The term hydropower refers to the power obtained from water motion. By the term 'power', primarily means the generation of electricity. A hydropower plant or hydroelectric power plant utilizes the kinetic energy or pressure energy of flowing water into electrical energy. Unlike conventional energy sources used for power generation, electricity obtained from hydraulic power contributes to zero greenhouse gas emissions.
