hydroelectric dams

Hydroelectric dams generate electricity by harnessing the energy of moving water. Water from a river or reservoir is directed through turbines when released, causing them to spin. These spinning turbines drive generators that convert mechanical energy into electrical power. Dams also help control water flow and provide benefits like irrigation and flood control. The process is renewable and clean since it relies on the natural water cycle, with no emissions. However, building dams can impact local ecosystems and communities, so their design and operation require careful planning to balance energy needs with environmental and social considerations.
