Hydropower

Hydropower, also known as hydroelectric power, is a form of renewable energy that harnesses the power of flowing or falling water to generate electricity. It is one of the oldest and most widely used renewable energy sources, providing around 16% of the world's electricity.

How Hydropower Works

Hydropower plants capture the energy of flowing or falling water to generate electricity. This is typically achieved through the use of a dam, which creates a reservoir of water at a higher elevation than the power plant. The water is then released from the reservoir, flowing through turbines that are connected to generators. As the turbines spin, they generate electricity, which can then be distributed to homes and businesses.

Benefits of Hydropower

There are several benefits to using hydropower as a source of energy. It is renewable, meaning it relies on the water cycle and will not run out as long as the sun continues to evaporate water and produce precipitation. Hydropower also produces minimal greenhouse gas emissions compared to fossil fuel-based power plants, making it a cleaner alternative. Additionally, hydropower can provide other benefits such as flood control, irrigation, and recreational opportunities around reservoirs.

Study Guide
