Wave power is a hydrodynamic form of energy stemming from the ocean’s surface waves in addition to the conversion of this energy to another form, such as electricity for example. This process is carried out via a generator or simply by pumping water up into a reservoir. Wave energy is qualified as a renewable source of energy, on the same lines as wind or hydropower. It must not be confused with tidal wave power or energy tapped from marine currents.

Ocean waves have a high energy density. There is considerable international activity attempting to develop technologies enabling us to capture this energy. Norway has, for a number of years now, placed a large emphasis on researching wave power.

Various kinds of experiments on the efficient exploitation of wave energy in this country have been carried out, but so far they have not led to any permanent installations. The waves along the Norwegian coastline represent, according to calculations, an energy potential of 700 TWh every year. In comparison, the yearly production today is approximately 125 TWh. Only a small part of the wave energy potential is to be considered as exploitable, but with new technology the proportion could be increased.
