The North Sea is the world's most developed offshore wind resource, with over 100 GW of capacity across hundreds of wind farms spanning UK, Netherlands, Germany, Denmark, Belgium, and Norway. Dogger Bank (3.6 GW, expandable to 6+ GW) is the world's largest offshore wind farm, using GE Haliade-X turbines with 220m rotor diameter.
Europe pioneered offshore wind and maintains a significant lead in deep-water and floating wind technology. The North Sea offers exceptional wind resources (capacity factors above 45%), shallow continental shelf geology, and proximity to major population centers. Nine North Sea nations signed the Ostend Declaration (2023) committing to 300 GW of offshore wind by 2050.
The strategic dimension extends beyond energy: offshore wind is creating a European industrial ecosystem encompassing turbine manufacturing (Vestas, Siemens Gamesa), installation vessels, subsea cables, grid interconnectors, and green hydrogen production. The North Sea is becoming Europe's renewable energy factory.
