Hydropower (hydroelectric Power)
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Hydropower, also known as hydroelectric power, is a form of renewable energy that utilizes the movement of water — typically from rivers, dams, or waterfalls — to generate electricity. It harnesses gravitational potential energy by directing water through turbines, which then convert mechanical energy into electrical energy. As one of the oldest and most established sources of renewable power, hydropower plays a significant role in global electricity generation.
