The global technical potential for wave energy is about 500GW of electrical energy, based on a conversion efficiency of 40 percent.

Global Resources - Eco Wave Power

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.
