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 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 can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. [2]
The Wudongde Dam (simplified Chinese: 乌东德坝; traditional Chinese: 烏東德壩; pinyin: Wūdōngdé Bà) is a large hydroelectric dam on the Jinsha River, an upper stretch of Yangtze River in Sichuan and Yunnan provinces in southwest China.
The emerging problems with hydropower production in places like the United States, China and Brazil represent what scientists and energy experts say is going to be a long-term issue for the ...
By funneling running water into a canal, this system can generate electricity
Hydropower dams can be classified as either "high-head" (greater than 30 m in height) or "low-head" (less than 30 m in height). [52] As of 2021, ICOLD's World Register of Dams contains 58,700 large dam records. [53]: 6 The tallest dam in the world is the 305 m-high (1,001 ft) Jinping-I Dam in China. [54]
Given this flow rate and the 96-metre fall, the Inga Falls alone has a potential to generate ~39.6 gigawatts (53,100,000 hp) of mechanical energy and nearly as much electrical energy. Inga Falls is currently the site of two large hydropower plants and is being considered for a much larger hydro power generating station known as Grand Inga.
Opinion column from Saluda River hydroelectric plants' official says the plants' value as a green-energy source should be recognized, preserved in SC. Opinion: Why hydropower deserves a key place ...
