Wave energy is superior to wind energy because it is a more concentrated form of energy that is more easily stored and is available for a greater period of time.
Wave energy consists of equal amounts of kinetic and potential energy. The kinetic energy can be converted to stored potential energy by building fixed reservoirs at sea.
Waves force water through the one way openings in the sides of the reservoirs to raise the water level above sea level. The resulting head of water can then generate electricity.
The reservoirs store energy to help meet peaks in electricity demand. They block the forward motion of waves and so are effective breakwaters. They would be a cost effective solution to the problems of coastal erosion and flooding.
