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.
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.

Overall, hydroelectric power can be far less expensive than electricity generated from fossil fuels or nuclear energy, and areas with abundant hydroelectric power attract industry. In Canada it's estimated there are 160,000 megawatts of undeveloped hydro potential.
Opinion column from Saluda River hydroelectric plants' official says the plants' value as a green-energy source should be recognized, preserved in SC.
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
Since 2019, wind power has exceeded hydro as the largest renewable electricity source. [8] At 132 years old, the plant in Whiting, Wisconsin is the oldest power plant still running in the US. [58] The Grand Coulee Dam is the largest plant for hydro and in general in the US, and the fifth-largest hydro plant in the world.
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. Since then numerous other hydroelectric power ...
The Federal Power Act is a law appearing in Chapter 12 of Title 16 of the United States Code, entitled "Federal Regulation and Development of Power".Enacted as the Federal Water Power Act on June 10, 1920, and amended many times since, [1] its original purpose was to more effectively coordinate the development of hydroelectric projects in the United States.
