Hydroelectric Energy

Hydroelectric energy is a renewable energy source that harnesses the power of flowing or falling water to generate electricity. It is one of the oldest and most widely used forms of renewable energy, providing around 16% of the world's electricity.

How Hydroelectric Energy Works

Hydroelectric power plants use the kinetic energy of flowing water to turn turbines, which then drive generators to produce electricity. The basic components of a hydroelectric power plant include a dam, reservoir, penstock, turbine, and generator.
