Why is there an urgent need to implement wave energy technologies?

Can anyone in the 21st century doubt the urgent need for wave energy technologies anymore? The severe shortage of electricity all around the world and our growing environmental consciousness all point to a new dawn in energy.

Although, the world’s electrical energy market is at $800-billion-a-year and rising. It has been estimated that there are at least 1.6 billion people still living without electricity today, and the world demand in developing countries is doubling every eight years.

The developing countries had spent as much as $40 to $60 billion a year on electricity by the end of the 20th century (G8, RETF, 2001), and still approximately 40% of the population in these countries remains without access to electricity. This means that the number of people throughout the world who have no electricity has hardly changed since 1970 (UNDP, 2000, p. 374).

In order to meet that demand, while limiting production of green house gases, wave energy technologies must be developed and implemented.

wave energy technologiesWave energy technologies have many clear advantages:

First of all, Two-thirds of the world’s population – 4 billion people – lives within 400km of the coast. Just over half the world’s population – around 3.2 billion – occupy a coastal strip 200km wide. Figures like these, and increasing human numbers, make the need for wave energy technologies’ implementation abundantly clear.

Second, today, we’re witnessing alarming increases in oil prices and a disappointing revival in coal consumption. A disaster on both fronts.

Even BP says we only have 150 years of coal left; 55 years of gas and 30 years of oil (2006). The global demand is increasing, and with it CO2 emissions (both are expected to rise by 60% within the next 25 years). As opposed, Wave energy technologies, are non polluting and some (For example: Eco Wave Power, headed by David Leb) offer electricity production for cheaper prices than traditional energy generation technologies , which reflects also on Short time scale between investing in the modular construction and benefiting from the revenue.

Any Wave energy technology is Renewable and sustainable resource, which reduces dependence upon fossil fuels , produces no liquid or solid pollution and when applied correctly has little or no visual impact.

Third, Sea waves are the result of the concentration of energy from various natural sources like wind, tides, ocean currents, sun, moon, and earth rotation. Therefore, Sea wave energy has the highest concentration of renewable energy, which can be extracted by a reliable wave energy technology.

While wind energy currently dominates the renewable energy industry, marine energy also holds huge potential. Wave energy contains roughly 1000 times the kinetic energy of wind, Therefore allowing smaller and less conspicuous wave energy devices to produce power.

In Conclusion, it’s not hard to see why wave energy technologies should be urgently implemented and what kind of demand wave power technologies will have in the nearest future.
