Question

Describe how hydro -energy can be converted into electrical energy.

Answer 1

Water is stored in dams to create potential energy. When water is released from sluice gates this potential energy is converted to kinetic energy. The kinetic energy then gives motion to the turbines to turn its shaft which then converts kinetic energy to electrical energy.

Answer 2

Answer:

In hydropower plants, a large amount of water is stored at a height. This stored water is then allowed to fall on rotating turbines. The force of the running water (kinetic energy of running water) causes the turbines of the plant to spin. The rotating turbines then spin the generator, which ultimately produces electricity. In this manner, the kinetic energy of the running water is converted into mechanical energy and then finally into electrical energy. Two limitations of Hydropower Energy are: Causes a change in the course of rivers and lot of land is submerged under water. Fish and wildlife are affected drastically.
