Renewables in Numbers


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 760MW since the end of 2008.

Chart 2 sets out the current mix of renewable electricity generation capacity in Scotland.  With the total now over 11GW, the sector is over three times bigger than it was at the end of 2008. Onshore wind is the biggest single technology, accounting for 70 per cent of installed capacity, while offshore wind, hydro and solar 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 total over 12GW.  Again, capacity increases in the short term will come from onshore wind, with nearly 4GW of capacity already consented and a further 3.5GW in planning. Offshore wind has 4GW already consented. There is also 306MW of solar projects at various stages of development and 396MW of wave and tidal projects either in planning or already consented.

The growing capacity of renewables has translated into a significant increase in renewable electricity output, which has more than tripled from 8,003GWh in 2007 to 26,473GWh in 2018.

Chart 4 shows that renewable electricity generation is now equivalent to approximately 76 per cent of Scotland’s electricity consumption.

Chart 5 shows output from different sources in 2018. Wind generated two thirds of all renewable electricity output in Scotland.

Hydro power contributed almost a fifth of renewable electricity output. 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. The 2018 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 2018.

Turnover from renewable energy activity in 2017 was £5,544 million, demonstrating how the sector continues to be an important driver of investment at a time of slow economic growth.


Chart 9 sets out the current mix of renewable heat generation capacity in Scotland. 2,010GW of renewable heat capacity was operational in Scotland by the end of 2018, which is up 4 per cent from 2017. Biomass accounts for 63 per cent of the total capacity followed by biomass combined heat and power which accounts for 20 per cent of the total.

In 2018, 5,230GWh of heat was produced from renewable sources; total heat output has increased by 14 per cent from 2017.

Progress towards Scotland’s 2020 renewable heat target is calculated by measuring renewable heat output as a percentage of annual heat demand. Renewable heat generation represented 6.3 per cent of Scotland’s non-electrical heat demand in 2018.

The Office of National Statistics (ONS) publish an annual survey on the low carbon and renewable energy economy in the UK, including direct and indirect activity, employees and turnover.

The survey found that in 2017, there were 17,700 full-time equivalent (FTE) employees in renewable energy in Scotland.
