What is hydro energy? Explain the principle of generating electricity from hydro energy.

How much hydro electric power is generated in India


Hydro energy is the kinetic energy possessed by flowing water.

The principle of generating electricity from hydro energy-water flowing from higher altitudes is accumulated at a dam placed at a height. This water is made to fall on a water turbine that is positioned near the base of the dam. The shaft of the turbine is in contact with the armature of a dynamo or an electric generator.
