Hydropower, or hydroelectric power, is a renewable source of energy that generates power by using a dam or diversion structure to alter the natural flow of a river or other body of water.

This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [1] Hydropower is a method of sustainable energy production. Hydropower is now used …

At hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine that spin to power a generator to produce electricity.

Nov 14, 2025 · Hydroelectric power is a form of renewable energy in which electricity is produced from generators driven by turbines that convert the potential energy of moving water into mechanical energy.
