WADEBRIDGE, ENGLAND - FEBRUARY 22: Grey skies gather above the wind turbines at Delabole Wind Farm on February 22, 2011 in Truro, England. Energy Secretary Chris Huhne reopened the Delabole wind farm, which was Britain's first commercial wind farm when it opened 20 years ago and has received a multimillion-pound redevelopment which will double potential output. The farm's original 10 turbines, which stood at 164ft, at the remote site near Wadebridge in Cornwall, have been replaced with four 325ft turbines, which will harness wind power more effectively and potentially generate enough to power 7,000 homes.
