World's largest wind turbines to be built off Yorkshire coast

Biggest offshore windfarm in North Sea will generate electricity for 4.5m homes

The largest offshore wind turbines ever built will begin powering millions of British homes using blades more than 100 metres long by the early 2020s.

Each of the new mega-turbines planned for the world's biggest offshore windfarm at Dogger Bank in the North Sea will reach 220 metres high and generate enough electricity for 16,000 homes.
