How does hydroelectric power work?

Hydropower plants capture the energy of falling water to generate electricity. A turbine converts ... Hydroplants range in size from "micro-hydros" that power only a few homes to giant dams like Hoover Dam that provide electricity for millions of people. The photo on ... Now all we need to do is a little mathematics. read more

Actually, hydroelectric and coal-fired power plants produce electricity in a similar way. In both cases a power source is used to turn a propeller-like piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. read more

Hydropower uses a fuel—water—that is not reduced or used up in the process. Because the water cycle is an endless, constantly recharging system, hydropower is considered a renewable energy. When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. read more

How Hydroelectric Power Plants Work By letting the water flow through turbines on their way to the sea, we can harness some of the kinetic energy of water to produce electricity. The flow and head determines the potential energy of a waterfall. read more

Hydroelectric power, also known as hydroelectric energy or simply hydroelectricity, supplies about 20% of the entire world’s electricity needs – About 88% of the total electricity that is generated from renewable energy sources. read more
