The exploration of alternative energy sources has become a primary concern of mankind even though fossil fuels are still the leader in the energy sector. Ocean wave energy as one of the promising alternatives, extensive research and development activities are happening around the world to explore new methods and to improve the existing methods. Among the existing plethora of technologies for harnessing renewable energy, the ones developed for wave energy have the lots of potential to be a major contributor to the amount of renewable energy produced. Almost all of these systems which use ocean waves to generate energy are void of pollution, that is to say that these systems do not produce any substances as side products that would harm the marine environment or the atmosphere in any way. With the rapidly decreasing amount of available fossil fuels and an even more expeditiously increasing population, and therefore and exceeding demand and consumption rate, it’s not long before the earth is going to be devoid of these precious resources. The need for more efficient technologies to harvest these available resources of renewable energies is more than ever. Although, there are numerous wind and solar farms built across the earth they are not enough adequate enough to suffice the need of 7.7 billion people around the globe. Water bodies cover around 70% of earth’s surface and these have immense potential for producing humungous amount of renewable energy. A shabby assessment shows that there is about 8,000-80,000 TWh/yr of wave energy present in the oceans. This enormous myriad of energy is enough to alleviate the problem of energy from the world.
