Ocean of Energy

The energy present in the ocean is so high that a mere 0.2% of the total untapped ocean energy can
power the whole of the world! The ocean holds a great deal of mechanical energy
in the form of its tides, waves and thermal energy from the sun. Tapping this
humongous amount of energy has been the fascination of many eminent scientists
and experts of the world. The ocean power technologies are based on the tried
and tested principles of hydrodynamics and electrical engineering.

The ocean water energy is present in the three forms, as said earlier.
The tides of the ocean hold a great amount ofenergy. Imagine the amount
of strength that is needed to make the water rise.This strength of the water
needs to be captured for its conversion intoelectricity. The electricity generation
from tides is done with the help ofturbines. As the tides flow into the blades
of the turbine, it makes thegenerator to turn and generate electricity.

Waves are the other form of ocean energy. The wave energy of the ocean is captured using point
absorbers that capture the energy from the surface or from pressure
fluctuations below the surface of ocean water.Ocean’s thermal
energy is created when the sun’s heat warms the ocean surface water whereas the
water below remains cold. The temperature difference can be used suitable in
the generation of electricity using turbines.
