Which country has the most offshore wind? China, with about half the world's
China had 48.4 GW of offshore wind at the end of 2025, about 52% of the world's 92.5 GW. The UK came second with about 17 GW, then Germany, the Netherlands and Taiwan. Between them, those five held nine-tenths of the world's offshore wind.
Offshore wind is still a small part of the world's wind power: 92.5 GW at sea against more than 1,200 GW on land, by the Global Wind Energy Council's count. But it is concentrated in a few countries with shallow, windy seas near big cities, and one country now has more than all the others together.
The ranking at the end of 2025
Offshore wind capacity by country, end of 2025
China built 6.6 GW at sea in 2025, more than 70% of the world's new offshore wind, and ended the year with 48.4 GW. Its own energy administration, which counts only what is connected to the grid, gave 47 GW at the end of 2025 and 49.8 GW by the end of September 2026. Jiangsu province alone had 13.5 GW, nearly 30% of the country's total.
The UK led the world until 2021 and is still far ahead of anyone else in Europe. WindEurope counts 16,982 MW at the end of 2025, including the turbines already working in farms not yet finished, such as Dogger Bank A. The Crown Estate, which leases the seabed, counts up to 16.5 GW in 46 fully commissioned farms with 2,820 turbines; RenewableUK said 16.1 GW in March 2026. The difference is how much of a farm still being built each one counts.
Germany passed 10 GW in the first half of 2026: 10,818 MW from 1,764 turbines feeding the grid at 30 June, by Deutsche WindGuard's count, against 9.6 GW at the end of 2025. The Netherlands had about 4.7 GW in ten North Sea farms, with the 760 MW Ecowende farm sending its first power in July 2026. Taiwan grew fastest outside China: from about 3.5 GW connected at the end of 2025 to 4.9 GW and 514 turbines by 1 September 2026, when Ørsted finished the 920 MW Greater Changhua 2b and 4.

Vietnam isn't ranked: its 1.8 to 2.1 GW of wind farms along the Mekong delta coast stand in tidal shallows, which some counts call offshore and others don't. Poland's first offshore farm, Baltic Power, sent its first power in July 2026.
The United States: from 0.2 to 1.7 GW in a year
At the end of 2025 only three small US farms were fully running: Block Island (30 MW), the Coastal Virginia pilot (12 MW) and South Fork (132 MW), 174 MW in all. In 2026 two big ones were finished despite a federal stop-work order and a suspension of leases that courts blocked: Vineyard Wind 1, 806 MW off Massachusetts, in full commercial operation from 29 October, and Revolution Wind, 704 MW off Rhode Island, in October. That makes 1,684 MW fully running. Dominion's 2.6 GW Coastal Virginia Offshore Wind has sent power since March 2026 and had 44 of its 176 turbines up by the end of October.

Method and sources
- No single list counts every country the same way, so each figure comes from the source that counts it best, named beside it: the Global Wind Energy Council's Global Offshore Wind Report 2026 for the world and China; WindEurope's "Wind energy in Europe: 2025 statistics" for European countries; and national governments for Taiwan, South Korea and the US. The latest figure for each country is dated and linked in the table.
- What's counted differs: grid-connected or installed turbines, and whether a farm still being built counts in part (WindEurope), not at all until it's finished (The Crown Estate) or at its full size once it starts (some national registers). China's energy administration counts what is connected; the China Wind Energy Association counts turbines installed, 49.2 GW at the end of 2025.
- Our own farm list, which the biggest farms come from, adds up to more than the published figures for Germany (our 11.7 GW), as Germany's register counts farms being commissioned at full size, for the Netherlands (our 6.2 GW), as it includes about 1.2 GW of farms in the IJsselmeer, a freshwater lake, which Dutch statistics count as wind on land, and less for China (45.8 GW), as Global Energy Monitor's list stops in February 2026.
