The world’s first offshore tidal energy turbine has been launched off the Devon coast in the UK, a first step to the possible widespread use of ocean tides for clean power.

The ocean turbine, developed by Hampshire-based Marine Current Turbines and Cornwall-based Seacore, is similar to a windmill sunk into the ocean and turned on its side.

Costing £3 million (about US$5 million), the turbine is located about 1.5 kilometers offshore from Lynmouth, 20 meters below the surface of the ocean.

It has a single 11-meter-long rotor blade and is capable of producing 300 kilowatts of electricity.
