Most electricity in Scotland is carried through the National Grid, with Scotland's renewable mix thus contributing to the electricity production of Great Britain as a whole. By 2012, over 40% of Scotland's electricity came from renewable energy, and Scotland contributed almost 40% of the UK's renewables output. At the end of that year there was 5,801 megawatts (MW) of installed renewables electricity capacity, an increase of 20.95% (1,005 MW) on the end of 2011. Renewable electricity generation in 2012 was a record high at 14,756 GWh – an increase of 7.3% on 2011, the previous record year for renewables output. In 2015, Scotland generated 59% of its electricity consumption through renewable sources, exceeding the country's goal of 50% renewable electricity by that year.
