hydropower

Definition

Hydropower is a form of energy that uses the power of moving water to generate electricity.

Hydropower plants are built dams that block the flow of water in a river or stream. The water behind the dam builds up pressure and is then released through turbines, which spin generators to create electricity.

Hydropower is a clean and renewable energy source. It does not produce greenhouse gases or pollutants, and it is a reliable source of energy.
