Orsted is relying on a plan to spend £15m ($20.3m) on artificial bird nests to finally secure a green light for the biggest project so far in its global offshore wind empire, the 2.4GW, up to £8bn Hornsea 3 off eastern England.

The global offshore wind market-leader has proposed building four nesting structures close to the North Sea coast to create breeding grounds for kittiwakes – a small grey, white and black bird whose “globally important” populations environmental groups claim are at risk of collision with the hundreds of giant turbines that would be deployed for Hornsea 3.
