Waves, caused by the blowing of wind over ocean surface, carry immense power. The power of the waves can help in generation of electricity for nearly 10% of the world’s demand.
Ocean wave power can be tapped using point absorbers, which resemble offshore buoys that measure environmental data except they are larger. Their popularity is due to their ability to absorb energy from oncoming waves in all directions.
The Ocean energy is created by taking advantage of the vast temperature difference. The temperature on the surface of the ocean water is different from the temperature of the water lying below it. It is hard to believe that in some areas, especially tropical, the surface water can be more than 40 degrees warmer than the deep water.
The ocean possesses mechanical energy from its tides, waves and thermal energy from the sun’s heat. The energy present in the ocean is so large that if tapped, only 0.2% of it will be sufficient to charge up the whole world’s demand.
