Hydropower stations generate electricity by using the energy of flowing water. They typically harness the power of rivers or dams, where water is stored in a reservoir. When released, the water flows through turbines, causing them to spin and produce electricity. This renewable energy source is efficient and can provide a consistent power supply. These stations can vary in size, from large facilities that serve entire cities to small systems that power individual homes. Hydropower is considered environmentally friendly, as it produces no direct emissions and helps reduce reliance on fossil fuels, contributing to a more sustainable energy future.
