Through dams, turbines, and water wheels, these endless sources of energy provide power to their regions, and in some cases, entire countries. You may wonder how this all works. Well the waves, flowing constantly, push rotors, panels, or paddles on large machinery. This forces the spokes or gears of the machinery to turn, much like a water wheel on a river would as water passes through it. This machinery in turn is connected to other devices that generate electricity or other forms of power.
