THE last year saw a huge increase in electricity produced by renewable energy sources according to environmental campaigners.

WWF Scotland said 2015 was a massive year for renewable and December was also a record breaking month with turbines able to supply enough electricity for every household for 25 days in the month.

Data from Weather Energy showed December to be a record month for wind power in Scotland and wind generated enough power to supply the electrical needs of 98% of Scottish households during 2014.

Wind generated enough power to supply over 100% of Scottish households during six months of 2014 and solar power met two-thirds or more of household electricity or hot water needs during 2014.

WWF Scotland's director Lang Banks said: "Without doubt, 2014 was a massive year for renewables, with wind turbines and solar panels helping to ensure millions of tonnes of climate-wreaking carbon emissions were avoided. With 2015 being a critical year for addressing climate change internationally, it's vital that Scotland continues to press ahead with plans to harness even greater amounts of clean energy."

For homes fitted with solar PV panels, during June and July there was enough sunshine in Aberdeen, Edinburgh, Glasgow or Inverness to generate an estimated 100% or more of the electricity needs of an average home.

The SNP welcomed the figures

Rob Gibson MSP, Convener of the Rural Affairs, Climate Change and Environment Committee, said: "These are very welcome figures which demonstrate that the Scottish Government's commitment to and investment in renewables is paying dividends.

"It is clearer than ever that Scotland's renewable electricity generation will play a key part in keeping the lights on across the UK and to keeping energy bills down.

"With Scottish Government support our renewables industry is going from strength to strength, bringing jobs and investment to Scotland, reducing carbon emissions and performing a key role in meeting our energy needs. But there is always more that can be done."
