What energy is a flowing river?

The energy of a flowing river is known as hydroelectric energy, or hydropower. Hydropower harnesses the energy of moving water to generate electricity. When a river flows, the force of the water can be used to turn turbines that generate electricity. The amount of energy generated depends on the volume and speed of the water flow, as well as the height from which the water falls. Hydropower is a clean, renewable source of energy and is an important part of many countries' energy mix.
