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 (from Ancient Greek ὑδρο-, "water"), also known as water power, 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 production.
Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro . [ 1 ] These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where ...

Map showing primary reservoirs and power plants of the Big Creek Project (many small diversion dams not shown) The Big Creek Hydroelectric Project is an extensive hydroelectric power scheme on the upper San Joaquin River system, in the Sierra Nevada of central California. The project is owned and operated by Southern California Edison (SCE). [1]
A screw turbine at a small hydro power plant in Goryn, Poland. The Archimedean screw is an ancient invention, attributed to Archimedes of Syracuse (287–212 BC.), and commonly used to raise water from a watercourse for irrigation purposes. In 1819 the French engineer Claude Louis Marie Henri Navier (1785–1836) suggested using the Archimedean ...
The primary purpose of the dam is hydroelectric power generation and it supports a 1,400 MW power station with 7 x 200 MW Kaplan turbines. The dam also provides navigation with a 500-ton flight of 3 ship locks and a 500-ton ship lift. [1] Other purposes include flood control, irrigation and recreation. [2]
