While hydro energy is generated by harnessing the power of moving water, wind energy is produced by converting the kinetic energy of wind into electricity. Annual wind generation totaled 300 million megawatthours (MWh) in 2019, exceeding hydroelectric generation by 26 million MWh. In the early 21st century, hydroelectric power was the most widely utilized form of renewable energy; in 2019 it accounted for more. . Hydropower is one of the oldest and largest sources of renewable energy. In 2024, it accounted for 27% of total U. utility-scale renewable electricity generation and 5. In addition, hydropower is flexible enough to integrate increasing amounts of wind and solar onto the. .
