Water already has energy, so all we have to do is capture and direct it. To make hydropower, water that flows from a river is usually held up by a dam and channeled past one or more turbines. The water catches and spins the turbines' blades. The spinning shaft of the turbine turns a generator, which produces alternating electric current. The current runs through power cables to a transformer, which converts it into high-voltage current that runs through power lines to the public.
