In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity. [2] According to the International Hydropower Association, the United States is the 3rd largest producer of hydroelectric power in the world in 2021 after Brazil and China. [3] Total installed capacity for 2020 was 102.8 GW.
In 2022, the IEA released a main-case forecast of 141 GW generated by hydropower over 2022–2027, which is slightly lower than deployment achieved from 2017–2022. Because environmental permitting and construction times are long, they estimate hydropower potential will remain limited, with only an additional 40 GW deemed possible in the ...
Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively ...
Snowy 2.0 Pumped Storage Power Station or Snowy Hydro 2.0 or simply Snowy 2.0 is a pumped-hydro battery megaproject in New South Wales, Australia.The dispatchable generation project expands upon the original Snowy Mountains Scheme (ex post facto Snowy 1.0) connecting two existing dams through a 27-kilometre (17 mi) underground tunnel and a new, underground pumped-hydro power station.

The Shilongba Hydropower Station is the first hydroelectric power plant in China. [31] It was built in Yunnan province in 1912, with a capacity of 240 kW. Due to the subsequent period of political and social instability, little additional progress was made in power infrastructure in the country at that time.
In 2023, The electrical energy generation mix was 29.4% natural gas, 26.9% hydroelectric, 21.6% wind, 13.7% biomass, 5.1% solar, 0.6% petroleum, 0.4% coal, and 2.5% other. Small-scale solar, which includes customer-owned photovoltaic panels, delivered an additional net 607 GWh of energy to the state's electrical grid in 2023.
The Grand Ethiopia Renaissance Dam (GERD), a key element of the country's energy expansion strategy, is expected to significantly increase the nation's energy capacity. With a planned capacity of 5,150 MW, GERD was 90% complete as of March 2023 and began producing 375 MW from one turbine in February 2022.
Biomass is by far the most important primary energy source in Nepal. Biomass comprises wood, agricultural residues and dung. One major problem with this is that burning these biomass substances for cooking is a common practice (87.3%) and thus exposes those living in the house to harmful air pollutants. [7]
