At hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine that spin to power a generator to produce electricity.
Hydropower is a type of renewable energy that uses the power of water flows to generate electricity. The energy that is generated by hydropower plants is clean, reliable, and sustainable, making it a relevant low-carbon alternative to fossil fuels in the fight against climate change.
Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity.
Hydropower, or hydroelectric power, is a renewable source of energy that generates power by using a dam or diversion structure to alter the natural flow of a river or other body of water.
What is hydropower? Learn its key benefits, how it works and the role hydropower plays in the global energy transition to clean electricity.
Discover how hydropower generates clean electricity. Learn the complete process from water flow to power grid, including turbines, generators, and efficiency factors.
There are two major approaches to generating electricity from hydropower: Storage hydroelectric systems store water for later use, which makes them a versatile resource for the grid. For example, large hydroelectric dams can be sited on rivers with valleys, creating an artificial lake or reservoir.
Today, hydropower provides about 16 percent of the world's electricity, generating power in all but two U.S. states. Hydropower became an electricity source in the late 19th century, a few...
