The UK is determined to get out of the "dunce corner" on renewables, Energy Secretary Chris Huhne said as he officially opened the world's largest offshore wind farm off the UK coast.
The 100-turbine Thanet wind farm off the coast of Kent will produce enough electricity to supply the equivalent of more than 200,000 homes a year, and brings the UK's total power from onshore and offshore wind to more than 5GW - enough to power all the homes in Scotland.
At a ceremony at sea to mark the launch of the new site, Mr Huhne said offshore wind was a key part of meeting the country's commitments to boost renewables, and the Government was focused on moving from the "frankly atrocious record" on green energy it had inherited.
Currently the UK sources just 3% of all its energy from renewables, against a target of 15% by 2020, and is 25th in the league table of 27 EU countries on action on green power.
Offshore wind power was part of ensuring secure, cheap energy supplies in the future, as well as providing jobs, Mr Huhne said.
But concerns were raised about the proportion of jobs created by the offshore wind industry going to British workers, and whether incentives such as £60 million promised for ports development to support the supply chain would survive the forthcoming Government spending review.
About 30% of the 3,500 jobs generated by the manufacture, construction and installation of the wind farm owned by Swedish company Vattenfall went to UK employees.
Mr Huhne said the ports funding was subject to the comprehensive spending review but said it would be foolish not to encourage in every way possible investment in the supply chain, to ensure as much as possible of the manufacture and skills for offshore wind were based in the UK.
"We need to make sure we have both the supply chain and the skills, and we will do what we can to make sure we are as attractive as we can be to investors," he said. "We do have an awful lot of wind and wave and tidal power and we are determined to have a supply chain to match."
While he said the opening of the Thanet wind farm and the reaching of the 5GW was a landmark for the UK, Mr Huhne said the country had a long way to go, and could easily encourage the industry to deliver 10 times as much wind energy by 2020.
