Scottish Renewables has compiled the key statistics on the development of Scotland’s renewable energy sector from a variety of government and industry sources in order to track the industry’s growing contribution to our energy needs, our economy and our environment.
These statistics are updated on a continuous basis as new data becomes available. Please select a chart on the right hand side to jump directly to it.
Scotland’s renewable electricity capacity has shown steady growth over the last few years with the average annual capacity increase over 635MW since the end of 2007.
Chart 1: Total Installed Capacity of Renewable Electricity in Scotland 2007-2015
Chart 2 sets out the current mix of renewable electricity generation capacity in Scotland. With the total now over 8GW, the sector is three times bigger than it was at the end of 2007. Onshore wind is the biggest single technology, accounting for over 70 per cent of installed capacity, while hydro, solar and bioenergy are Scotland’s other major sources of renewable power.

There is significant additional capacity in development across Scotland, with projects either in planning or already consented which now total over 12GW. Again, capacity increases in the short term will come from onshore wind, with over 4GW of capacity already consented and a further 3.5GW in planning. There is also 265MW of bioenergy projects at various stages of development and 381MW of wave and tidal projects either in planning or already consented.

Chart 4: Electricity Consumption and % Renewables Output
Chart 5 shows output from different sources in 2015. Onshore wind generated almost two thirds of all renewable electricity output in Scotland.
Hydro power contributed over a quarter of renewable electricity output, and while other technologies such as biomass and marine energy currently make a smaller contribution, they have massive potential for growth in the future.

Chart 6 shows that the proportion of the country’s power generation from renewables has also grown significantly in recent years – up from 20 percent in 2009 to 43 per cent in 2015. The 2015 figures show that renewables was once again the single largest contributor to electricity generation in Scotland.

Renewable energy is one of the best tools we have to combat climate change. As the proportion of renewable electricity in Scotland grows it gradually displaces the need to generate electricity from polluting fossil fuels, reducing total carbon emissions. The chart below sets out estimates of CO2 emissions displaced by renewables from 2009 to 2015.
In 2015 renewable electricity generation displaced approximately 13,400,000 tonnes of CO2, equal to around 28 per cent of Scotland’s carbon emissions in 2014, the most recent year for which carbon emission statistics are available.

The sector continues to be an important driver of investment at a time of slow or negative economic growth. The value of investments in projects commissioned in each year can be estimated using the total additional capacity in each technology multiplied by estimates of capital cost per MW.
Using this methodology, the table shows projects with a total capital cost of £910.6 million were commissioned in 2015.
Chart 9 sets out the current mix of renewable heat generation capacity in Scotland. 1,504MW of renewable heat capacity was operational in Scotland by the end of 2015, which is up 47 per cent from 2014. Biomass accounts for 60 per cent of the total capacity followed by biomass combined heat and power which accounts for 26 per cent of the total.
Chart 09: Renewable Heat Capacity by Technology in Scotland 2015
In 2015, 4,165GWh of heat was produced from renewable sources, total heat output has increased by 37 per cent from 2014.
Chart 10: Renewable Heat Output by Technology in Scotland 2015
Progress towards Scotland’s 2020 renewable heat target is calculated by measuring renewable heat output as a percentage of annual heat demand. Based on 2014 annual heat demand of 79,207GWh and with renewable heat output estimated to be 4,165GWh, renewable heat generation represents an estimated 5.3 per cent of Scotland’s non-electrical heat demand in 2015.
Chart 11: Progress Towards the 2020 Heat Target
The Department for Business, Innovation and Skills published a report on, ‘The size and performance of the UK Low Carbon Economy’, in March 2015. The report focussed on the years 2010 to 2013.
The report estimated that there are 21,000 jobs in Scotland across 9 renewable energy sectors. The largest single sector was onshore wind, followed by solar PV, and heat pumps.
