How much UK electricity comes from renewables?

DESNZ's quarterly Energy Trends release reports electricity generation by source, including the renewable share, and the annual Digest of UK Energy Statistics (DUKES) gives the full picture each July.

Check whether a figure is the share of generation or of supply (which includes imports), and whether it covers a quarter or a year, as wind output varies a lot by season.

Terms used in this answer

• Net zero
  The UK's legal target for 2050: greenhouse gas emissions reduced so far that any remaining emissions are balanced by removals from the atmosphere.
• Provisional figures
  Early estimates published before all data are in, so users get timely figures. They are expected to be updated when later data arrive.
• Revisions
  Changes to previously published figures, made when more complete data, improved methods or updated seasonal factors become available. A normal part of official statistics.
• Outturn
  The actual recorded figure for a period that has ended, as opposed to a plan, budget or forecast for it.
• Calendar year
  January to December. Used for GDP annual totals, registered deaths and many international comparisons, unlike the April to March financial year.

Where the figures come from
