The UK wind power sector has reached a capacity of 4GW of installed wind energy across the country.
The UK wind power sector now powers the equivalent of all Scotland's household needs, or 2.3 million homes, according to figures from the British Wind Energy Association (BWEA).
The benchmark was achieved after the final commissioning of three wind farms – a 38MW wind farm at Longpark, a 30MW facility at Dun Law and the first phase of Dong Energy's 173MW Gunfleet Sands offshore wind farm.
The UK added the latest 1GW of capacity in less than a year.
It took 14 years to deliver the first gigawatt in 2005, 20 months for the second and 18 months for the third.
