Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.
The Nurek Dam is an earth-fill embankment dam on the Vakhsh River in Tajikistan. Its primary purpose is hydroelectric power generation and its power station has an installed capacity of 3,015 MW. Construction of the dam began in 1961 and the power station's first generator was commissioned in 1972. The last generator was commissioned in 1979 and the entire project was completed in 1980 when Tajikistan was still a republic within the Soviet Union, becoming the tallest dam in the world at the time. At 304 m (997 ft), it is currently the second tallest man-made dam in the world, after being surpassed by Jinping-I Dam in 2013. The Rogun Dam, also along the Vakhsh in Tajikistan, may exceed it in size when completed.

The Mingachevir Dam is an earth-fill embankment dam on the Kura River just north of Mingachevir in Azerbaijan. It serves several purposes to include hydroelectric power production and water storage for irrigation. The Mingachevir reservoir, behind the dam, supplies water to the Upper Qarabag and Upper Sirvan Channels which help irrigate about 1,000,000 ha of farmland in the country. Its six Francis turbine-generators were overhauled or replaced with 70 megawatts (94,000 hp) sets in 2000. Mingachevir reservoir has a storage capacity of 15.730 cubic kilometres (12,753,000 acre⋅ft), covering 605 km2 (234 sq mi). The length of the dam is 1,550 metres (5,090 ft), its width is 16 metres (52 ft) and height is 80 m (260 ft). It is the largest hydroelectric power station in the South Caucasus, is located over Kur river and not far from Mingachevir city.
Canyon Ferry Dam is a concrete gravity dam in a narrow valley of the Missouri River, United States, where the Big Belt Mountains and the Spokane Hills merge, approximately 68 miles (109 km) downstream from the confluence of the Gallatin, Madison, and Jefferson rivers, and about 20 miles (32 km) east of the city of Helena, Montana. The dam is for flood control, irrigation, recreation and hydroelectric power. The building of the dam created a reservoir known as Canyon Ferry Lake.
The Boguchany Dam is a large hydroelectric dam on the Angara River in Kodinsk, Krasnoyarsk Krai, Russia. It has an installed capacity of 2,997 MW. Construction of the power plant was completed when a ninth and final generator was brought online in January 2015.
Richard B. Russell Dam is a concrete-gravity and embankment dam located on the Savannah River at the border of South Carolina and Georgia, creating Richard B. Russell Lake. The dam was built by the U.S. Army Corps of Engineers between 1974 and 1985 for the purposes of flood control, hydroelectricity, recreation, additional stream flow regulation, water supply, and fish and wildlife management. The concrete structure of the dam spans 1,904 feet (580 m) and rises 210 feet (64 m) above the riverbed, housing a hydro-power plant with an installed 600 megawatts (800,000 hp) capacity. The Richard B. Russell Dam is the final large dam completed by the U.S. Army Corps in the Savannah River Basin and lies 30 miles downstream from the Hartwell Dam (1962) and 37 miles (60 km) upstream from the J. Strom Thurmond Dam (1954).
The Brno Reservoir, previously known as the Kníničky Reservoir is a reservoir on the Svratka River at the northwest edge of the city of Brno, Czech Republic. The construction of a dam on the 56th kilometre of the Svratka River, and the resultant flooding of the river valley containing the village of Kníničky, created the reservoir. The reservoir used to serve as a water reserve for Brno. It remains a place for recreation, and also a source of electric power. The administrator of the Brno Reservoir is the state-owned enterprise Povodí Moravy, s.p.
The Bao-Tavera Dam Complex refers to two earth-filled embankment dams located about 15 km (9.3 mi) south of Santiago in Santiago Province of the Dominican Republic. The Bao Dam on the Bao River is 113 m (371 ft) and withholds a reservoir with a maximum storage capacity of 280,000,000 m3 (230,000 acre⋅ft). It is the second tallest dam in the country behind the Monción Dam. The Tavera Dam, about 8 km (5.0 mi) east of Bao Dam, on the river Yaque del Norte is 82 m (269 ft) high and has a reservoir with a capacity of 170,000,000 m3 (140,000 acre⋅ft). A 1.5 km (0.93 mi) canal connects each reservoir, making them a complex. The purpose of the complex is to provide municipal water, water for irrigation and to generate hydroelectric power.
