Britain solidified its position as global leader in offshore wind power by announcing the launch of the London Array, a 630MW project near the mouth of the Thames River.
The 1.5 billion pound ($2.3 billion) wind farm has 175 Siemens 3.6MW turbines, enough to power half a million homes. The project is owned by Denmark's Dong Energy, Germany's E.On and Masdar, of Abu Dhabi. Its official launch makes it the largest offshore wind project in the world.
The UK currently has more than 3.6GW of offshore wind power capacity, with around 18GW expected by the end of the decade.
