Two giant next generation wind turbines will soon start generating electricity off the coast of Essex. The 6 megawatt turbines - which stand 148 metres tall - have been added to the Gunfleet Sands demonstration project.

They're the first of their kind to be constructed offshore anywhere in the world. They're expected to start generating electricity by the spring. Owners Dong Energy have signed an agreement to have 300 similar turbines built for projects around the UK.
