Figures from the Department for Business, Energy and Industrial Strategy show 679,827 megawatts per hour (around 680 gigawatts) of renewable electricity were generated in Wiltshire in 2019.
This was 202 per cent more energy than the 225 GWh produced in 2014, the earliest year of data available.
The biggest producer of energy in Wiltshire last year was solar power, which generated 574,672 MWh – 85 per cent of the total.
This was followed by landfill gas, which is created by the decomposition of organic materials in a landfill (8 per cent), and anaerobic digestion, which is the breakdown of organic material by micro-organisms to produce biogas – which generated a further 35,472MWh (5 per cent).
Renewable electricity generated around a third of the UK's total energy last year (120,675 GWh) – almost double the amount it did in 2014.
Offshore wind farms, which are turbines located at sea, and onshore wind farms, based on land, were responsible for 27 per cent of the UK's total.
