Marine Energy
Marine power from wave and tide is still in relatively early stages of development with many competing innovations being tested worldwide (example); however, there is great energy in the oceans and the potential will show in the next decades.
Tidal Turbine Farms are often a series of seabed-mounted turbines in a tidal flow. These flows are often strong in narrow openings between islands or in estuaries and tidal ocean bays. Where there is a narrow gap between islands and the seabed rises from deep water, the tidal flow is forced to quicken as a large volume of water is forced through a narrow channel, such as in the Gulf of Corryvreckan on the West Coast of Scotland.

The Pelamis Wave Energy Converter is a large floating articulated tube, which converts the energy of the waves to hydraulic energy, which in turn drives electrical turbines. |
