Hydropower plants generate electricity by harnessing the energy of flowing water. They typically use a dam to create a reservoir, where water is stored. When released, the water flows through turbines, which spin and convert the kinetic energy into electrical energy. This process is efficient and produces no direct emissions, making it a clean energy source. These plants can vary in size, from large facilities that supply power to entire cities to small plants that serve local communities. The use of hydropower contributes to reducing reliance on fossil fuels and helps combat climate change by lowering greenhouse gas emissions.
