The North Sea's offshore wind farms are increasingly vulnerable to hybrid warfare, raising questions about security responsibilities among national authorities and private firms. As of early 2026, over 100 wind farms operate in the region, but incidents involving drones often go unreported, complicating security measures. Experts call for clearer frameworks for responsibility among public and private sectors. The importance of offshore wind energy has grown, especially in light of geopolitical tensions, with Europe aiming to ramp up capacity significantly by 2031.
