Generation History
Historical British electricity generation data going back to 2012.
Annual generation by fuel type (TWh)
Absolute electricity generation in terawatt-hours by fuel type each year since 2012. The steep decline in coal and steady growth of wind and solar is clear - as is the overall fall in total generation driven by efficiency improvements and reduced industrial demand. The most recent year is partial.
Annual electricity mix (%)
How Britain's electricity generation mix has changed since 2012. Coal has been almost entirely replaced by renewables and gas; wind and solar have grown from a small fraction to major contributors. Each bar shows the proportional share of generation from each fuel type for that year.
Annual carbon emissions
Megatons of CO₂ equivalent from British electricity generation each year. The long-term downward trend reflects the rapid decarbonisation of the grid. The most recent bar is a partial estimate based on data available so far this year.
Annual gas generation
Electricity generated from gas each year, in terawatt-hours. Gas has fallen from the single largest source to a smaller, more flexible role as wind, solar and nuclear have grown. The most recent year is partial.
