Water reservoir of river dams
|
Detailed explanation-1: -In an impoundment facility, a dam is used to control the flow of water stored in a pool or reservoir. When more energy is needed, water is released from the dam. Once water is released, gravity takes over and the water flows downward through a turbine. As the blades of the turbine spin, they power a generator.
Detailed explanation-2: -Hydroelectric energy is power made by moving water.
Detailed explanation-3: -Hydroelectric power (HEP) with dams uses the energy of rivers to make electricity .
Detailed explanation-4: -As the water flows down through the dam its kinetic energy is used to turn a turbine. The generator converts the turbine’s mechanical energy into electricity. This electric energy then goes through various transmission processes before it reaches you.
Detailed explanation-5: -A hydroelectric reservoir is a large collection of water behind a hydroelectric dam that makes use of potential energy of water for generating electricity. This water is held back by the dam and a small amount is allowed to fall down the base of the dam to generate electricity when it is needed.
