John Hutton, the secretary of state for business, enterprise and regulatory reform, will propose the creation of up to 33 gigawatts of offshore wind energy at a European energy industry conference in Berlin. He will call for companies to invest in large-scale farm development to generate enough power for up to 25 million homes in the next 12 years. That would require around 7,000 turbines, or one every half-mile, Hutton told the BBC1 Politics Show yesterday. He admitted that "tough choices" would have to be made if the UK wanted to respond to climate change and become more self-sufficient.
