In 2023, some 100 miles off the coast of north-east England, the world’s largest wind turbines will start generating electricity. This first phase of the Dogger Bank offshore wind farm development uses General Electric’s Haliade X, a turbine that stands more than a quarter of a kilometre high from the surface of the sea to the highest point of the blade tip.
If you placed one in London, it would be the third-tallest structure in the city, taller than One Canada Square in Canary Wharf and just 50 metres shorter than the Shard. Each of its three blades would be longer than Big Ben’s clock tower is tall. And Dogger Bank will eventually have nearly 300 of these giants.
