Offshore wind energy capacity worldwide has been on a continual annual growth since 2009. In 2024, the global offshore wind capacity reached * megawatts, an increase compared to the previous year. In 2024, more than megawatts of offshore wind power were newly installed and connected to the grid.
Bottom-fixed vs. floating wind turbines
Offshore wind farms are located over bodies of water – usually in the sea – where wind reaches higher speeds than land. Two main different types of turbines can be found in offshore wind farms: bottom-fixed turbines are built on fixed foundations in shallow waters, whereas floating turbines are assembled on floating structures in deeper waters, where bottom-fixed farms cannot be installed. Overall, floating farms allow more area to be exploited for wind energy generation, reduce visibility from the shore, and can be assembled in areas with more powerful and constant winds. As of 2024, China was the leading country in total offshore wind capacity.
Offshore wind energy in Europe
Europe was the second-leading region in offshore wind, holding some of the largest wind farms across the globe in 2025. Within Europe, the United Kingdom has the highest offshore wind power capacity, at some **Â gigawatts. This was followed by Germany, the Netherlands, Denmark, and Belgium.Â
