Question: What community composes 60% of the population whose country 's offshore wind power farm holds an electrical capacity of 30 megawatts ?

text: Offshore wind power
Largest offshore wind farms
Four offshore wind farms are in the Thames Estuary area : Kentish Flats , Gunfleet Sands , Thanet and London Array . The latter was the largest in the world until September 2018 . See also : List of offshore wind farms and Lists of offshore wind farms by country
Offshore wind power or offshore wind energy is the use of wind farms constructed in bodies of water, usually in the ocean, to harvest wind energy to generate electricity. Higher wind speeds are available offshore compared to on land, so offshore wind powers electricity generation is higher per amount of capacity installed, and NIMBY opposition to construction is usually much weaker. Unlike the typical use of the term offshore in the marine industry, offshore wind power includes inshore water areas such as lakes, fjords and sheltered coastal areas as well as deeper-water areas. Most offshore wind farms employ fixed-foundation wind turbines in relatively shallow water. As of 2020, floating wind turbines for deeper waters are in the early phase of development and deployment. At the end of 2017, the total worldwide offshore wind power capacity was 18.8 gigawatt (GW). All the largest offshore wind farms are currently in northern Europe, especially in the United Kingdom and Germany, which together account for over two-thirds of the total offshore wind power installed worldwide. As of September 2018, the 659 MW Walney Extension in the United Kingdom is the largest offshore wind farm in the world. The Hornsea Wind Farm under construction in the United Kingdom will become the largest when completed, at 1,200 MW. Other projects are in the planning stage, including Dogger Bank in the United Kingdom at 4.8 GW, and Greater Changhua in Taiwan at 2.4 GW. The cost of offshore wind power has historically been higher than that of onshore wind generation, but costs have been decreasing rapidly in recent years to $78/MWh in 2019. Offshore wind power in Europe has been price-competitive with conventional power sources since 2017.
