Waves are caused by winds blowing across the surface of the sea. The wind energy is transferred to the waves and thus the stronger the wind is the more energy is into the waves. So wave energy is the energy contained in the waves. Wave Energy is proportional to the square of the height of

The UK is a global leader in Wave and Tidal Energy, both being Renewable Energy Sources, RESs, and both under the umbrella of Ocean Energy. As a world leader UK has long term plans for the commercialization of the technologies which enable the efficient exploitation of the power of the waves and tides. Wave and
