Enery Resources: Wave power

Waves are caused by the wind blowing over the surface of the ocean. There is tremendous energy in the ocean waves. The total power of waves breaking around the world is estimated at 2-3 million megawatts. One way to catch wave energy is to focus the waves into a narrow channel, increasing their power and size and then used directly to spin turbines. There are no big commercial wave energy plants, but there are a few small ones.
