The commissioning of Airtricity's 72 MW Braes of Doune wind farm in Scotland has pushed the UK past the 2 GW milestone. Britain's wind industry took just 20 months to achieve its second gigawatt of installed wind capacity, a far cry from its first which took 14 years. It makes the UK the seventh country in the world to install over 2 GW of wind. Secretary of State for Trade and Industry Alistair Darling, who pushed the button to start Braes of Doune, says: "We want 20% of our electricity to come from these green sources and we are working hard on removing any barriers to achieving that aim. Wave, tidal and offshore wind power can make a significant contribution in future but onshore wind energy is delivering capacity here and now."
