Question

Why is hydroelectric power considered a renewal source of energy?

Answer 1

Renewal Source of Energy

1. Renewal sources of energy are inexhaustible sources of energy that may be replenished after a short period.
2. Examples are wood, water, wind, etc.

Hydroelectric power is considered a renewal source of energy because:

1. A dam is constructed to create a water reservoir. Each time it rains, the reservoir will be refilled with water.
2. The amount of water on Earth has almost always been constant. The heat energy of the Sun drives the flow of water on earth in the form of the water cycle.
3. Therefore, hydroelectric power is considered a renewal source of energy.
