At the plant level, water flows through a pipe—also known as a penstock—and then spins the blades in a turbine, which, in turn, spins a generator that ultimately produces electricity. Most conventional hydroelectric facilities operate this way, including run-of-the-river systems and pumped storage systems.
There are more than 2,000 hydropower plants operating in the United States, making hydropower the country''s largest renewable energy source. In this article, we''ll take a look at how falling water creates energy and learn about the hydrologic cycle that creates the water flow essential for hydropower.

Hydroelectric plants are more efficient at providing for peak power demands during short periods than are fossil-fuel and nuclear power plants, and one way of doing that is by using "pumped storage", which reuses the same water more than once.
Modern hydropower plants are helping to accelerate the clean energy transition, providing essential power, storage, flexibility and climate mitigation services. Hydropower is also a key asset for building secure, clean, electricity systems and reaching global net zero targets.
How Does Hydropower Work? Hydropower technologies generate power by using the elevation difference, created by a dam or diversion structure, of water flowing in on one side and out, far below, on the other.
How hydropower works A typical hydroelectric plant is a system with three parts: a power plant where the electricity is produced, a dam that can be opened or closed to control water flow,
Hydropower is energy in moving water. People have a long history of using the force of water flowing in streams and rivers to produce mechanical energy. Hydropower was one of the first sources of energy used for electricity generation, and until 2019, hydropower was the leading source of total annual U.S. renewable electricity
Hydroelectric power is a form of renewable energy in which electricity is produced from generators driven by turbines that convert the potential energy of moving water into mechanical energy. Hydroelectric power plants usually are located in dams that impound rivers, though tidal action is used in some coastal areas.
How Does Hydropower Work? Most of the country''s hydropower facilities were built in lakes, streams, and rivers decades ago. They often used large dams that block the water''s flow, creating a pool of water above the structure. One or more pipes give that pooled water a path to surge downhill.
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.
