Gas-fired turbines are still the greatest source of electricity and have seen a more prominent growth in supply shares than renewable sources in the past four years. In 2019, nearly 41 percent of electricity generated was from gas-fired turbines. Indigenous production by major power producers fell to 278,858 gigawatt hours in 2018, while auto producers contributed 51,539 gigawatt hours’ worth. Domestic consumption amounted to 105,065 gigawatt hours that same year, having also seen a net decline since 2000.
In terms of sales of publicly distributed electricity, figures amounted to 281.61 terawatt hours in 2018, having fallen from over 300 terawatt hours sold in 2013. Approximately 250 terawatt hours of publicly distributed electricity were sold in England and Wales, while Scotland recorded 23.55 terawatt hours. By comparison, electricity export volumes reached 2,225 gigawatt hours in 2018.
