Question

water used in generation of hydroelectricity is a renewable source of energy --- comment on the statement

Answer 1

1. Yes,water used in generation of hydroelectricity is a renewable source of energy.
2. This is because in this method,potential energy from water dropped from height is converted to mechanical energy which on moving a turbine produces electrical energy.
3. So,we infer that it's only the conversion of physical sources of energy from one form to other.
4. No chemical changes in water is taking place,so water can be reused many times to generate electricity as many times as required.
