Hüdroelektrijaam

Hüdroelektrijaam, also known as a hydroelectric power station, is a facility that generates electricity using the energy of falling water. This energy is typically harnessed from rivers or reservoirs by building a dam. The dam creates a difference in water level, allowing water to flow from a higher elevation to a lower one through turbines.

The falling water spins the blades of a turbine, which is connected to a generator. The generator then converts the mechanical energy of the spinning turbine into electrical energy. This electricity is then transmitted through power lines to consumers.

The design and operation of a hüdroelektrijaam can vary significantly depending on the site and the amount of water available. Some are massive structures with large reservoirs, while others are smaller run-of-river facilities that utilize the natural flow of a river. The environmental impact of hüdroelektrijaamad is a subject of ongoing discussion, with considerations including effects on aquatic ecosystems, land use, and greenhouse gas emissions from reservoir decomposition.

Hüdroelektrijaamad are a significant source of renewable energy worldwide. They are known for their long operational lifespan and relatively low operating costs once constructed. The capacity of a hüdroelektrijaam can range from a few kilowatts to several gigawatts, depending on its size and the water flow.
