Hydropower or hydro-energy is a form of renewable energy that uses the water stored in dams and flowing in rivers to create electricity. Falling water rotates the blades of a turbine, which spins a generator and converts mechanical energy into electrical energy. Hydropower accounted for 6.6% of total U.S. electricity generation in 2019.
