Beyond the horizon off the coast of North Yorkshire, a quiet revolution is emerging from the waves of the North Sea. More than 80 miles from land, hundreds of the world’s most powerful wind turbines have begun reaching into the air as construction progresses on the biggest windfarm ever built. Almost 200 turbines, each almost as tall as the Eiffel tower, will soon rise above the submerged Doggerland to populate an expanse of sea as large as North Yorkshire itself. The Dogger Bank windfarm is an engineering feat that marks a step change in the growth of renewable energy. Each steel structure, weighing 2,800 tonnes, has been designed to soar more than 250 metres from where their heels are buried in the seabed to the top of each 107-metre blade. The staggering scale of the turbines means that each one can generate enough electricity to power 16,000 homes, at less than the average price of electricity in the wholesale energy market.
