More than a quarter of Scotland’s electricity now comes from renewable energy sources, according to official statistics.
The amount of energy generated by wind, wave and solar power increased by a fifth last year and now accounts for 27% of the nation’s energy consumption.
Energy efficiency drives are also thought to have accounted for a four per cent drop in the amount of power consumed.
Climate change minister Roseanna Cunningham said: “Scotland is blessed with abundant natural energy sources, particularly in our seas, and today’s figures follow a steady trend towards Scotland’s energy becoming greener and cleaner.
“As consumption here fell by four per cent in 2009, exports to the rest of the UK are rising, with nearly a quarter of all our electricity produced going south, contributing further to sustainable economic growth.
“Green energy developments coming on stream in 2009, such as the Whitelee wind farm, are now feeding ever greater amounts of green power into the grid.
“As Scottish Renewables’ new figures recently demonstrated, Scotland is on track to hit our interim target of 31% of all electricity demand to be met from renewables by 2011.”
WWF Scotland said that with the right political commitment, Scotland could be 100% powered by renewable energy sources by 2020.
