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 Three Gorges Dam in Hubei, China, has the world's largest instantaneous generating capacity at 22,500 MW of power. In second place is the Baihetan Dam , also in China, with a capacity of 16,000 MW.
In 2013 the ICSHP and UNIDO published the World Small Hydro Power Development Report. According to Li Yong, Director-General of UNIDO, the report was "a world first compilation of global small hydropower data". [10] The report assessed small hydro power development in 149 countries across 20 regions from over 60 different authors. [11]
The project has stoked concerns about displacement and environmental impact downstream in India and Bangladesh.

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 ...
[21] [25] The world's renewable share of TFC was 18% in 2018: 7% traditional biomass, 3.6% hydropower and 7.4% other renewables. [26] In the period 2005–2017 worldwide final consumption of coal increased by 23%, of oil and gas increased by 18%, and that of electricity increased by 41%. [21]
All 7 dams are the largest power-generating bodies respectively, before the Jebel Ali Power Plant at 8,695 MW, the largest non-renewable energy-generating facility in the world. The currently planned Grand Inga Dam would be nearly twice the size of the Three Gorges Dam at 39,000 MW , surpassing all power-generating facilities once it passes the ...
