Ocean waves are caused by the wind blowing across the sea. There is tremendous amount of energy stored in the ocean waves. Waves are a powerful source of energy.

The total power of waves breaking around the coastlines all over the world is estimated at 2-3 million megawatts. One way to harness wave energy is to focus the waves into a narrow channel which increases their power, size and impact. The waves can then be directed into a catch basin or may be used directly to spin turbines. There are a few small wave energy plants, but no big commercial ones. The best potential can be harnessed on small, on-shore sites for immediate future. These produce enough energy to power local communities.
