Wave Energy in the North Sea

Wave Energy Resource.

Wave energy is generally considered to be the most concentrated and least variable form of renewable energy. It is the high power density of wave energy that suggests it has the capacity to become the lowest cost renewable energy source. The World Energy Council has estimated that approximately 2 terawatts (2 million megawatts), about double current world electricity production, could be produced from the ocean waves.

Wave energy is proportional to the square of the wave height; double wave height = 4x more energy. In our part of the North Sea, the usual wave height for which a device gets designed would lie around 3-4m in area's where the mean yearly wave energy density would lie between 10 and 20 kW/m wave front. In oceans that could be up to 7m wave heights and 60-70 kW/m wave front.
