Hydropower harnesses the energy of flowing or falling water to generate electricity.

Run-of-the-river plants use the existing flow of a river to generate electricity without creating a reservoir.

A reservoir is an artificial lake created by a dam to store water for various purposes, including hydropower generation.

The turbine in a hydropower plant converts the kinetic energy of flowing water into mechanical energy, which is then used to drive the generator.

The penstock is a pipe that controls the flow of water from the reservoir to the turbine in a hydropower plant.

Pumped-storage hydropower plants use reversible turbines to pump water uphill during periods of low electricity demand and generate electricity by releasing the water downhill during periods of high demand.

The tailrace is the channel that carries water away from the turbine and back into the river or other water body.

Tidal hydropower plants utilize the tides to generate electricity by capturing the energy of the rising and falling tides.

The construction of dams can fragment aquatic habitats, disrupting the natural flow of water and affecting fish and other aquatic life.

China is the largest producer of hydropower electricity in the world, accounting for over a quarter of the global hydropower generation.

Potential power is the maximum theoretical power that can be extracted from a flowing stream of water, calculated based on the water's flow rate and elevation.

Impoundment hydropower plants create a reservoir behind a dam, which provides a head of water for electricity generation.

The spillway is a structure that controls the flow of water from a reservoir in a hydropower system, preventing flooding and maintaining a safe water level.

Wave hydropower plants utilize the energy of waves to generate electricity, typically using devices that capture the wave's motion and convert it into electricity.

Hydropower is a reliable renewable energy source because it can generate electricity continuously as long as there is water flowing.
