Ocean Energy

Ocean energy from tides, waves, currents and heat is still an underexploited energy source. © THINKSTOCK

The ocean, which covers 71% of the Earth’s surface, is an underexploited source of energy. Techniques harnessing tides, waves, ocean currents, heat and salinity are being developed to generate sustainable electricity. This energy source, which remains underused, is set to grow in the coming years.

Tidal Energy

Tidal energy is based on the surge of enormous amounts of water as ocean tides rise and fall. This energy is recovered through a dam built across an estuary.

At sea, the force of the waves is considerable and omnipresent. However, not every country has the same potential. Those with the best exposure have developed different wave energy recovery techniques.

Using heatIn the field of statistical thermodynamics today, heat refers to the transfer of the thermal agitation of the particles making up matter... from ocean waters to produce energy is not a new idea. However, a number of major technical obstacles must be overcome and there are few suitable sites for these facilities. Heat pumps can sometimes also offer an alternative solution for harnessing the thermal energy of the ocean.

Ocean current energy can be harnessed using underwater turbines, also known as tidal turbines, to generate powerIn physics, power is the amount of energy supplied by a system per unit time. In simpler terms, power can be viewed as energy output.... This technology has potential in many regions around the world. However, projects are still in the experimental stages.
