The amount of heat generated by renewable sources in Scotland grew by 36% during 2014.
Figures published by the Energy Saving Trust, on behalf of the Scottish Government, estimate over 1 gigawatt of renewable heat capacity in operation in Scotland in 2014.
This accounts for around an estimated 3.8% of the total non-electrical heat demand.
This report, covering heat from heat pumps (ground and air) biomass, waste and solar thermal, is used to measure progress towards the Scottish Government’s target of 11% heat coming from renewables by 2020.
Also, non-electrical heat demand in Scotland reduced by 2% in 2013 (the most recent year data is available for), to just over 82,000 GWh.
Earlier this year the Scottish Government published its Heat Policy Statement which aims to largely decarbonise the heat system by 2050.
This sets out how Scotland might use less energy for heat, and how low carbon heat can reach more householders, business and communities and a clear framework in investment in the future of heat in Scotland.
Energy Minister Fergus Ewing said: “I am pleased 2014 has seen the biggest step change in heat demand generated from renewable sources, a significant step forward to decarbonising heating.
“We are committed in helping support households and business across become more energy efficient and use more low carbon and renewable heat sources.”
However, Mr Ewing said there is continuing uncertainty about the Renewable Heat Incentive (RHI). He said Scotland will press for commitment from the UK Government to the long term sustainability of the RHI beyond next year to provide confidence for funders and stimulate investment in renewable heat technologies.
The Scottish Government has its own programmes such as the Home Renewables Loan Scheme, Resource Efficiency Scotland and the Low Carbon Infrastructure Transition Programme to provide support to encourage uptake of renewable heat technologies.
