Ocean wave energy: Technology Information Sheet
Oceans represent a huge, predictable resource for renewable energy.The main forms of ocean energy are waves, tides, marine currents,salinity gradient and temperature gradient. Wave and tidal energy arecurrently the most mature technologies. Wave energy is mostly derivedfrom a transfer of wind energy to the surface of the ocean. The energyis measured in terms of kilowatts per metre of wave front (kW/m) andcan be converted to electricity in a number of ways.
