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 ]
Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power, 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 production.
This is a list of U.S. states by total electricity generation, percent of generation that is renewable, total renewable generation, percent of total domestic renewable generation, [1] and carbon intensity in 2022.
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.

Run-of-river schemes (without reservoir) totally depend on the flow of the river, which might be low in times of drought. Sometimes a run-of-river hydropower plant sits behind another hydropower plant in a cascade, so that their operation does not depend on the river but on the upstream size of the reservoir feeding the upstream hydropower plant.
A calculation of the historic average annual hydropower production baseline for the facility, along with the supporting water flow information and corresponding actual annual power production data for the period of record. Such calculations must be based on the units operating capacities as authorized under a Commission's license or exemption.
