The earth’s oceans are its circulatory system, transporting physical and thermal energy, moderating temperatures, CO2 levels and most importantly providing a habitable planet. Wave energy is a significant renewable energy resource, as water density is approximately 1000 times greater than that of air, relatively providing much higher energy flux densities, and enabling high energy extraction from smaller devices.
Wave Energy is created as a result of weather variations in heat and pressure, generating winds blowing across a great fetch impinging on the oceans below. Waves can gather and transfer large amounts of energy extremely efficiently.
The map below shows that there are many high wave energy sites located close to high population densities, and the figures represent kilowatts per meter of wave front.
