John Samuel Eastwood (1857, in Minnesota – 1924, in California) was an American engineer who built the world's first reinforced concrete multiple-arch dam on bedrock foundation at Hume Lake, California, in 1908, and was one of California's pioneers of hydroelectric power production.
The size of hydroelectric plants can vary from small plants called micro hydro, to large plants that supply power to a whole country. As of 2019, the five largest power stations in the world are conventional hydroelectric power stations with dams. [21]
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 .
Hoover Dam 1936, Nevada/Arizona – 2,080 MW, world-renowned and once the largest hydroelectric power station in the world; Grand Coulee Dam 1942, in Washington – 6,809 MW, largest power station in country; Dez Dam 1963, in Iran – 520 MW, major project in country at time of construction; Gordon Dam 1978, in Tasmania – 432 MW, tallest dam ...
As of 2005, hydroelectric power, mostly from dams, supplies some 19% of the world's electricity, and over 63% of renewable energy. [74] Much of this is generated by large dams, although China uses small-scale hydro generation on a wide scale and is responsible for about 50% of world use of this type of power. [74]
Hoover Dam impounds Lake Mead and is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 30 mi (48 km) southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California.
An artist's conception of what Atlantropa might have looked like as seen from space. The central feature of the Atlantropa proposal was to build a hydroelectric dam across the Strait of Gibraltar, which would have generated enormous amounts of hydroelectricity [4] and would have led to the lowering of the surface of the Mediterranean Sea by as much as 200 metres (660 ft), opening up large new ...
The High Dam has also improved the efficiency and the extension of the Old Aswan Hydropower stations by regulating upstream flows. [31] At the time of completion, it was the largest power station in Africa and the 6th largest hydroelectric power station in the world. All High Dam power facilities were completed ahead of schedule.
