The planet’s biggest and most powerful wind turbines have begun generating electricity off the Liverpool coast, cementing Britain’s reputation as a world leader in the technology. Danish company Dong Energy has just finished installing 195m-tall 32 turbines in Liverpool Bay that are taller than the Gherkin skyscraper, with blades longer than nine London buses. The project is the first time the 8MW turbines have been commercially used anywhere in the world. Collectively they now have a capacity of 5.3GW, generating enough electricity to power 4.3m homes.
