Hydropower supply refers to the generation of electricity using the energy of flowing or falling water. This renewable energy source harnesses the kinetic energy of water, typically from rivers or dams, to turn turbines that produce electricity. It is a clean and sustainable way to generate power, as it does not emit greenhouse gases during operation. The efficiency of hydropower supply can vary based on factors like water flow and the design of the hydropower plant. Many countries rely on this energy source to meet their electricity needs, making it a significant component of the global energy mix.
