The oceans accumulate solar energy in the forms of wave, current and thermal energy. The oceans also contain kinetic energy due to tidal changes. Utilisation of ocean energy can contribute to stabilisation of the global climate, abolish energy shortage, reduce pollution, and provide additional energy that can enable people all over the world to produce more food, products and services.

Possible utilisation of ocean energy include generation of electricity, providing energy for seafood and aquaculture plants, production of fresh water from seawater, purification of seawater, and production of hydrogen.
