Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [1] Hydropower is a method of sustainable energy ...
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity , almost 4,210 TWh in 2023, [ 1 ] which is more than all other renewable sources combined and also more than nuclear power . [ 2 ]
Hydropower Dams built in Ethiopia provided over 1,500 MW of capacity by 2010. The four largest dams were built between 2004 and 2010. Gilgel Gibe III added 1,870 MW in 2016. The Grand Ethiopia Renaissance Dam (GERD), a key element of the country's energy expansion strategy, is expected to significantly increase the nation's energy capacity ...
Hydroelectric power plant near the Blue Nile Falls. The levelized cost of electricity is often considered to be lowest for hydropower if compared to other possible types of electricity generation. In addition, hydropower is by far the most favorable way of producing electricity when looking at the energy returned on energy invested. This makes ...
In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity. [2] According to the International Hydropower Association, the United States is the 3rd largest producer of hydroelectric power in the world in 2021 after Brazil and China. [3] Total installed capacity for 2020 was 102.8 GW.
Hydropower accounts for 95.73% [35] of the supply sold by the Quebec Crown-owned utility. Five of Hydro-Québec's hydroelectric facilities are rated above 2,000 MW — the Manic-5, La Grande-4, La Grande-3 La Grande-2-A and Robert-Bourassa stations — while 7 others have a capacity of over 1,000 megawatts.

Although claimed to be the first such station in the world when it opened in 1965 by the Visit Cruachan website, Drax Group PLC's Cruachan Power Station [15] was preceded by the Ffestiniog Power Station in North Wales, which opened in 1963, [16] and on a smaller scale by the North of Scotland Hydro-Electric Board's Sron Mor power station opened ...
Hydropower accounts for about 20% of Russia's total electric power production. The country has 102 hydropower plants in operation, with RusHydro the world's second-largest hydroelectric power producer. [31] Hydro generation (including pumped-storage output) in 2020 was 196 TWh, which represents 4.4% of world hydroelectricity generation. In 2020 ...
