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 ]
As far back as 1995, the government of Uganda planned to construct a hydropower station at the site of the Karuma Falls. Initially, Norpak, a Norwegian energy company, was awarded the contract to perform the feasibility study and the environmental impact assessment (EIA) for the dam.
Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass , which is mainly used for heating , and 3.4% from hydroelectricity .
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 ]
Roughly about 10 to 15 percent of California's energy generation is from large hydroelectric generation that is not RPS-eligible. [6] The significant impact of dams on the power sector, water use, river flow, and environmental concerns requires significant policy specific to hydropower.
Water is required for all life, but since ancient times, mankind has also employed this natural resource for other specifically human productive uses. Millennia ago man learned to navigate on water, learned to dam and divert it for irrigation and build aqueducts and canals to carry it where possible, and learned to convert the power of moving water to mechanical energy to perform work.

This is a list of operational hydroelectric power stations in the United States with a current nameplate capacity of at least 100 MW.. The Hoover Dam in Arizona and Nevada was the first hydroelectric power station in the United States to have a capacity of at least 1,000 MW upon completion in 1936.
Conduit hydroelectricity (or conduit hydropower) is a method of using mechanical energy of water as part of the water delivery system through man-made conduits to generate electricity. Generally, the conduits are existing water pipelines such as in public water supply . [ 1 ]
