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 ...
Hoover Dam's initial 1,345 MW power station was the world's largest hydroelectric power station in 1936; it was eclipsed by the 6,809 MW Grand Coulee Dam in 1942. [20] The Itaipu Dam opened in 1984 in South America as the largest, producing 14 GW , but was surpassed in 2008 by the Three Gorges Dam in China at 22.5 GW .
The Kurobe Dam (黒部ダム), or Kuroyon Dam (黒四ダム), is a 186 m (610 ft) high variable-radius arch dam located on the Kurobe River in Toyama Prefecture, Japan. The tallest dam in Japan , [ 1 ] it supports the 335 MW Kurobe No. 4 Hydropower Plant and is owned by Kansai Electric Power Company .
Upper Falls Power Plant is a hydroelectric power plant and dam complex on the Spokane River located in Downtown Spokane, Washington.The facility is located on the Upper Spokane Falls in Riverfront Park where the river splits into three branches around snxw meneɂ (formerly known as Canada Island) [3] and Havermale Island.
A photo showing an older flashboard system of the Holyoke Dam and the Canal System's original gatehouse. The river between Holyoke and South Hadley contained what was known as the "Great Falls" a natural 53-foot (16 m) drop in the river approximately 86 miles upstream of the Atlantic Ocean.
Removal of this privately-owned hydropower dam in western North Carolina will be a boon for rafters, kayakers and tubers by allowing the river to flow freely for nearly 80 miles (129 kilometers).
The project has stoked concerns about displacement and environmental impact downstream in India and Bangladesh.
The Report of the World Commission on Dams also includes in the "large" category, dams which are between 5 and 15 m (16 and 49 ft) high with a reservoir capacity of more than 3 million cubic metres (2,400 acre⋅ft). [45] Hydropower dams can be classified as either "high-head" (greater than 30 m in height) or "low-head" (less than 30 m in height).
