The information requested is not held centrally. However, we do have some information that may be useful. The reply refers to electricity and heat, both of which can be generated from renewable sources.It is estimated that, in 2015, Scotland generated enough renewable electricity to power the equivalent of around 4.6 million households - close to double the number of households in Scotland. A year earlier, in 2014, this figure was just over 4 million households. Provisionally, 56.9% of Scotland’s gross electricity consumption came from renewables in 2015.Figures published by the Energy Saving Trust in October 2015, on behalf of the Scottish Government, estimate over 1 gigawatt of renewable heat capacity was in operation in Scotland in 2014. This accounts for an estimated 3.8 per cent of the total non-electrical heat demand.The Scottish Government does not hold a complete dataset of the number of homes heated from renewable sources. Latest data on the number of domestic Renewable Heat Incentive (RHI) accreditations in Scotland, which represents a proportion of renewably heated homes, shows there have been 10,280 accreditations to the domestic RHI scheme from April 2014 (when the scheme commenced) up to end of June 2016. This equates to 21% of all UK installations as at end of June 2016.Further information is also available in the Energy Saving Trust’s Renewable Heat Report. Additionally a proportion of homes are heated via district heating supplied with renewable heat. Further data on the scale of deployment of district heating is expected later this year.It should be noted that renewable generated energy will be used both domestically and non-domestically
