What is Hydropower?

Hydroelectric power, one of the cleanest and most sustainable technologies, is a renewable source that harnesses the power of moving water (rivers or reservoirs) to generate electricity. It works by passing water through turbines that convert kinetic energy into mechanical energy and then into electrical energy using a generator. In addition, it allows water flow to be regulated and energy to be stored, contributing to the stability of the electrical system.
