  • Floating wind turbines: Offshore floating wind turbines exploit the greater power provided by stronger, more consistent offshore winds. This new technology enables the installation of energy conversion systems in depths greater than 50 metres, which means that these floating generators can access a denser energy resource, at the same time as limiting the visual impact from the coast.
  • Ocean thermal energy conversion: Ocean thermal energy conversion (OTEC) technology exploits the temperature gradient between surface seawater (at around 25 °C) and the much colder water (around 5 °C) found at depths of 1,000 metres or more.
  • Wave energy: Waves are generated by the wind as it blows across the sea surface. Energy is transferred from the wind to the waves and the capture of that energy to do useful work.
