Hydroelectric power

Hydropower, also known as hydroelectric power, is generated by transforming the potential energy existing between two bodies of water located at different altitudes or elevations into electrical energy. In order to take advantage of this difference in height, hydraulic infrastructures are built to extract the maximum potential from this local resource.

How Hydropower Works

HOW DO WE GET ENERGY FROM WATER? Hydropower, 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.Hydropower relies on the endless, constantly recharging system of the water cycle to produce electricity, using a fuel—water—that is not

Hydropower Plant – Types, Components, Turbines and Working

The kinetic energy is used to rotate the turbine and the turbine is connected with an alternator to generate electrical energy. A hydroelectric power plant is a non-convention power plant and widely used to generate electricity from a renewable source of energy.
