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 ...
Hydroelectric power has been a popular method of energy dating back to the late 19th century. The main advantage of using hydropower is that it is a clean form of energy, otherwise known as "green" energy. Since the process of using waterpower does not require burning fossil fuels, it is more environmentally friendly.

For example, a low-head hydro power plant with hydrostatic head of few meters to few tens of meters can be classified either as an SHP or an LHP. [30] The other distinction between SHP and LHP is the degree of the water flow regulation: a typical SHP primarily uses the natural water discharge with very little regulation in comparison to an LHP.
However many run-of-the-river hydro power plants are micro hydro or pico hydro plants. Much hydropower is flexible, thus complementing wind and solar, as it not intermittent. [92] In 2021, the world renewable hydropower capacity was 1,360 GW. [73] Only a third of the world's estimated hydroelectric potential of 14,000 TWh/year has been developed.
The only known surviving example of this type of engine used in power production, dating from 1851, is found at Hacienda Buena Vista in Ponce, Puerto Rico. [4] In 1820, Jean-Victor Poncelet developed an inward-flow turbine. In 1826, Benoît Fourneyron developed an outward-flow turbine. This was an efficient machine (~80%) that sent water ...
In the mid- to late 18th century John Smeaton's scientific investigation of the water wheel led to significant increases in efficiency, supplying much-needed power for the Industrial Revolution. [ 2 ] [ 3 ] Water wheels began being displaced by the smaller, less expensive and more efficient turbine , developed by Benoît Fourneyron , beginning ...
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.
