Waves are caused by wind blowing over water. Water covers around three-quarters of the earth’s surface. The World Energy Council estimates that the energy that can be harvested from the world’s oceans is equal to twice the amount of electricity that the world produces now.

Ireland is located at the centre of one of the most favourable climates for ocean wave energy in the World. The medium-term practical resource has been identified by the Marine Institute as around 800MW installed capacity. However, currently there are no commercially available wave energy converters which could be used to exploit this resource.
