Updated November 14, 2026. China is the country with the most offshore wind power in the world: it had 47,390 MW installed at sea at the end of 2025, 52% of global offshore wind capacity, according to statistics from the International Renewable Energy Agency (IRENA). It is followed by the United Kingdom, with 16,650 MW, and Germany, with 9,733 MW. Worldwide there were 91,141 MW of offshore wind spread across just 19 countries, and none of them is in Latin America.
Offshore wind places turbines at sea, where the wind is stronger and steadier than on land. In 2024 it generated 203.5 TWh, more than double all the electricity Chile generated that year (92.8 TWh, according to IRENA), but only 0.66% of the planet's electricity. This data sheet brings together the ranking of countries by installed capacity, how much they generate, who depends on it most and how it has grown since 2015.

China, the world power of wind at sea
Ten years ago China had just 559 MW at sea. In 2021 it installed about 17,400 MW in a single year and overtook the United Kingdom, which had led offshore wind since its beginnings: that year China reached 26,390 MW against the UK's 11,255 MW. Since then it has kept adding between roughly 4,000 and 7,000 MW a year.
Even so, offshore wind supplies only 0.8% of China's electricity, because its power system is enormous: China generated more than 10 million GWh in 2024. In China, wind at sea is a source of growth, not yet a backbone of supply.

Offshore wind in the world, 2015-2025
Global offshore wind capacity rose from 11,733 MW in 2015 to 91,141 MW in 2025, almost eight times more, according to IRENA's country-by-country sum (Energía Futura calculation). The Global Wind Energy Council (GWEC) reaches a similar figure: its Global Offshore Wind Report 2026, presented in June, counted 92.5 GW at the end of 2025 and 9.3 GW installed during that year, the third-best year in history, according to Offshorewind.biz.
| Year | World capacity (MW) | World generation (GWh) |
|---|---|---|
| 2015 | 11,733 | 36,297 |
| 2020 | 34,340 | 104,367 |
| 2021 | 54,268 | 137,924 |

In Europe, recent growth came from France, which went from 14 MW in 2021 to 1,902 MW in 2025 with its first commercial farms, and from the Netherlands, which almost doubled its capacity since 2020. In Asia, Taiwan went from 128 MW in 2020 to 3,587 MW in 2025 and is now fifth in the ranking.
Wind at sea is also steadier than on land. With IRENA data, Denmark's offshore farms generated in 2024 the equivalent of running at full power 42% of the hours of the year, and the UK's, 35% (capacity factor calculated by Energía Futura with end-2024 capacity). GWEC says offshore wind could quadruple to about 420 GW by 2035, with more than 50 GW already under construction, according to Down To Earth, although the same report warns that some projects are stalled by costs and permits.
The countries that depend most on wind at sea
By share of electricity, the ranking changes. Denmark, which opened the world's first offshore wind farm in 1991, generated 27.3% of its electricity from wind at sea in 2024. It is followed by the United Kingdom (17.1%), the Netherlands (12.5%) and Belgium (9.3%). They are countries with shallow coasts on the North Sea, where turbines are fixed to the seabed with piles a few kilometres offshore.

Turbines at sea are also the largest in the world: the record belongs to a 26 MW Dongfang Electric turbine connected in Shandong (China) in October 2025, and outside China the largest model is Siemens Gamesa's, at 21.5 MW. The full list of those giants is in our ranking of the largest wind turbine in the world.

No Latin American country has offshore wind capacity in operation, according to IRENA. Chile has one of the best wind resources in the region, but its coast becomes deep a few kilometres from shore, which requires floating turbines, more expensive than those fixed to the seabed. In addition, onshore wind and solar in the north deliver much cheaper energy. The largest onshore projects, which compete with offshore wind, are in our ranking of the largest wind farm in the world.
Floating technology is what would suit Chile best. It is still at an early stage worldwide: Norway has 95 MW at sea, largely floating, and Japan has 300 MW offshore, including a floating farm off Goto island.

Methodology
Capacity corresponds to IRENASTAT's offshore wind energy category, in its update published in the second half of 2026, with data at the end of 2025. 2025 generation is not yet available, so 2024 is used. The world total is the sum of the countries in the database and may differ slightly from other sources, such as GWEC (92.5 GW). Vietnam appears with 1,104 MW because IRENA counts as offshore its near-shore farms in the tidal areas of the Mekong delta.
To compare offshore wind with all clean sources, our ranking of countries with the most renewable energy shows what share of each country's electricity comes from the sun, wind and water.

Which country depends most on offshore wind?
Denmark, which generated 27.3% of its electricity from wind at sea in 2024, followed by the United Kingdom (17.1%) and the Netherlands (12.5%).
