Hydroelectric dam at Imatrankoski spans the Vuoksi River in Finland, with turbulent water flowing through open spillways and forested banks on both sides. Row of large blue hydroelectric turbine generators inside the Hoover Dam power plant, with an American flag hanging above. Aerial view of Hoover Dam spanning the Colorado River between steep rocky cliffs in Black Canyon, with Lake Mead behind the dam and arid mountains surrounding the area. This diagram shows how a tidal power barrage generates electricity, with cross-sections of a structure containing sluice gates and a turbine placed between the ocean and a tidal basin. Water flows through the turbine as tides change, converting tidal energy into hydroelectric power. The upper image depicts high tide with water held in the tidal basin, while the lower image shows water flowing back through the turbine at low tide. Norris Dam stretches across a wide river, with a road running along the top and a power station below, surrounded by forested hills in East Tennessee.

hydroelectric power, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy. In the early 21st century, hydroelectric power was the most widely utilized form of renewable energy; in 2019 it accounted for more than 18 percent of the world’s total power generation capacity. Hydroelectric Power Timeline For the generation of hydroelectric power at dams, water is collected or stored at a higher elevation and...
