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 ...
The Hydropower Sustainability Assessment Protocol (HSAP) is a global framework for assessing the sustainability of hydropower projects. The Protocol defines good and best practice at each stage of the life-cycle of a hydropower project across twenty-four environmental, social, technical and economic topics.
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 ]

Guri Dam, a hydroelectric dam in Venezuela. Hydroelectric plants convert the energy of moving water into electricity. In 2020, hydropower supplied 17% of the world's electricity, down from a high of nearly 20% in the mid-to-late 20th century. [80] [81] In conventional hydropower, a reservoir is created behind a dam.
Inside the Robert-Bourassa generating station, in northern Quebec, the world's largest underground power station, with an installed capacity of 5,616 MW.. An underground power station is a type of hydroelectric power station constructed by excavating the major components (e.g. machine hall, penstocks, and tailrace) from rock, rather than the more common surface-based construction methods.
Solar potential of Nepal. Nepal gets most of its electricity from hydropower sources, but it is looking to expand the role of solar power in its energy mix. [10] The average global solar radiation in Nepal varies from 3.6 to 6.2 kWh/m 2 /day, sun shines for about 300 days a year, the number of sunshine hours amounts almost 2100 hours per year with an average of 6.8 hours of sunshine each day ...
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]
