On one hand, the United Kingdom, a major offshore wind market, produced nearly 20 per cent of the electricity it generated from offshore wind alone in 2025. Amisha Patel, executive director, Global Offshore Wind AllianceExperts point to supply chain crunches, operational backlogs and inflation that elevated project costs after years of steady declines as major factors for this tough period for offshore wind. “There’s a global market that’s affected by global challenges,” Louise Efthimiou, floating offshore wind manager at the World Forum Offshore Wind, a nonprofit advocacy group based in Germany and Japan, told Mongabay in an interview. That model is already pursued in China, which dominates global offshore wind capacity by a large margin. “I would say that circular economy principles are essential for scaling offshore wind sustainably, if offshore wind is to move from tens of gigawatts to hundreds of gigawatts,” Kolios said.
