The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. But hydroelectric power doesn't necessarily require a large dam.
Also asked, which country uses the most hydroelectric power?
The map above shows the amount of electricity produced by hydroelectric dams in each of the nations of the world. The United States leads the world in hydroelectric dams, mostly due to its high level of technology and plentiful supply of rivers. Canada, Brazil, and China also produce a large amount of hydroelectricity.
Who uses the most hydropower?
Hydropower is the most important and widely-used renewable source of energy. Hydropower represents about 17% (International Energy Agency) of total electricity production. China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States (Source: Energy Information Administration).
Which country produces the most hydroelectric power?
China produces the most electricity from hydroelectric power, some 856.4 billion kilowatt hours a year – more than double the amount produced by Brazil, in second place. The top three is completed by Canada, which produces 376.7 billion kilowatt hours a year.
