Hydroelectric power is a form of renewable energy that generates electricity by using the flow of water. Typically, water from rivers or dams is directed through turbines, which spin and produce electricity. This process harnesses the kinetic energy of moving water, making it a clean and sustainable energy source. The main components of a hydroelectric power system include a dam, a reservoir, and turbines. The dam creates a height difference, allowing water to flow down through the turbines. This method of energy production is efficient and can provide a significant amount of electricity to homes and businesses.
