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 ...
In 2015 hydropower generated 16.6% of the worlds total electricity and 70% of all renewable electricity. [46] The major advantage of conventional hydroelectric systems with reservoirs is their ability to store potential power for later production on demand. When used in conjunction with intermittent sources like wind and solar, a constant ...
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 ]
An example of a small hydro power plant, Sveta Petka. A final noted advantage of small hydro over larger hydropower developments or fossil fuel plants is an element of environmental justice. In a number of communities which lack essential electricity access small hydro offers a reliable and clean source of electricity.

The amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. [4] Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. [5]
Much of the electricity generated by Hydro-Québec Generation [7] comes from hydroelectric dams located far from load centres such as Montreal. Of the 33,000 MW of electrical power generated, over 93% of that comes from hydroelectric dams and 85% of that generation capacity comes from three hydroelectric generation centers: James Bay, Manic-Outardes, and Newfoundland and Labrador Hydro's ...
Low-head hydro power refers to the development of hydroelectric power where the head is typically less than 20 metres, although precise definitions vary. [1] Head is the vertical height measured between the hydro intake water level and the water level at the point of discharge.
