Hydropower - Page 4

Hydropower, also known as hydroelectric power, is a form of renewable energy that harnesses the energy of flowing or falling water to generate electricity. This process typically involves the construction of dams on rivers, creating reservoirs that store water. When water is released from the reservoir, it flows through turbines, causing them to spin and generate electricity via connected generators. Hydropower is one of the oldest and most widely used sources of renewable energy, providing a significant portion of the world's electricity supply. It is favored for its ability to produce large amounts of energy with relatively low greenhouse gas emissions compared to fossil fuels. Additionally, hydropower can be adjusted quickly to meet fluctuating energy demands, making it a reliable component of many energy grids.
