In 2010, the US Energy Information Agency said "offshore wind power is the most expensive energy generating technology being considered for large scale deployment". [5] The 2010 state of offshore wind power presented economic challenges significantly greater than onshore systems, with prices in the range of 2.5-3.0 million Euro/MW. [36]

All the most powerful turbines are offshore wind turbines. This list also includes the most powerful onshore wind turbines, although they are relatively small compared to the largest offshore ones. As of June 2024, the most powerful wind turbine in operation is the world's first 18MW semi-direct drive offshore wind turbine, developed by ...
The first turbine was in place by the end of May 2021, and on 23 June 2021 Ørsted announced that the 16th turbine to be added to the Hornsea Two array was the 1,000th turbine they had installed in UK waters, fifteen years after they installed their first, which was part of the 30-turbine Barrow Offshore Wind Farm, off the coast of Cumbria.

Robin Rigg Wind Farm is Scotland's first offshore wind farm. It was constructed by E.ON at Robin Rigg, a sandbank in the Solway Firth midway between the Galloway and Cumbrian coasts. It first generated power for test purposes on 9 September 2009, [ 1 ] and was completed on 20 April 2010.
The exploration of offshore wind energy started with the introduction of monopile foundations for wind turbines in a range from 1 up to 3MW in water depth of about 10 to 20m during the 1990s. [2] Germany has been facing water depths up to 40m, when it joined this new field of renewable energy .
Blue H Technologies - World's first floating wind turbine (80 kW), installed in waters 113 metres (371 ft) deep in 2007, 21.3 kilometres (13.2 mi) off the coast of Apulia, Italy The world's second full-scale floating wind turbine (and first to be installed without the use of heavy-lift vessels), the 2 MW WindFloat, about 5 km offshore of Aguçadoura, Portugal University of Maine's 20 kW ...
It also lists the largest offshore wind farms currently under construction, the largest proposed offshore wind farms, and offshore wind farms with notability other than size. As of 2022, Hornsea 2 in the United Kingdom is the largest offshore wind farm in the world at 1,386 MW .
