A hydropower plant is a facility that generates electricity by using the energy of flowing or falling water. Typically located near rivers or dams, these plants convert the kinetic energy of water into mechanical energy, which is then transformed into electrical energy through turbines and generators. Hydropower is considered a renewable energy source because it relies on the natural water cycle. It produces minimal greenhouse gas emissions compared to fossil fuels, making it an environmentally friendly option for electricity generation. Many countries, including China and Brazil, utilize hydropower as a significant part of their energy mix.
