उत्तर
The kinetic energy in flowing water or the potential energy in water reservoir is a conventional energy source. In hydroelectric power plants, the potential energy in water stored in a dam is converted into the kinetic energy of water. Fast flowing water is brought from the dam to the turbine at the bottom of the dam. The kinetic energy of the flowing water drives the turbine. The turbine in turn drives the generator to generate electricity.
Potential energy in water → kinetic energy in flowing water → kinetic energy in turbine → Electrical energy
