hydropower diagram
Water flowing downstream at dams produces electricity. As the water passes through the dam’s powerhouse, it falls from the upstream level behind the dam to a lower downstream level. The water is moving with tremendous force and is guided down to the turbine. As it strikes the turbine blades, the water turns the turbine like a propeller. The turning turbine spins coils of wires inside a large generator mounted above it, converting the mechanical energy of falling water into electrical energy. Transmission lines then carry the electricity to homes and businesses.
