Notes on individual values
- Partly Ember's estimate: the file has no 2023 generation for 1 of the 209 countries and economies with generation for an earlier year, and Ember's methodology says it estimates a country's missing years from its historical trends of demand and generation by source.
- Partly Ember's estimate: the file has no 2024 generation for 15 of the 209 countries and economies with generation for an earlier year, and Ember's methodology says it estimates a country's missing years from its historical trends of demand and generation by source.
- Partly Ember's estimate: the file has no 2025 generation for 116 of the 209 countries and economies with generation for an earlier year, and Ember's methodology says it estimates a country's missing years from its historical trends of demand and generation by source.

What was done to it
Read release_generation_yearly_global.csv, last modified by Ember on 2026-09-22 (Ember gives no version label, so that date is the vintage), and kept the rows for Area 'World'.
Code: pipeline/src/envdash/transforms/energy/ember_yearly.py · code sha256 56848f85fd86402d… · inputs ea214963f4a9… 67c5eaac3bfb…
Checked that the shares mean what is published: the nine non-aggregated sources (Solar, Wind, Hydro, Bioenergy, Other renewables, Nuclear, Coal, Gas, Other fossil) add up to 100%, Clean generation is Renewables plus Nuclear, Renewables is the five renewable sources, and the Clean share is Clean over Total generation, each to within the rounding of the printed values.

Marked a year preliminary, with a note giving the count, when the file has no Total generation for that year for a country or economy that has it for an earlier year. Ember's data methodology (PDF last modified 2026-09-22, sha256 67c5eaac3bfb…; both sentences were found on pages 10, 12 before publishing) says it estimates the latest annual generation from monthly data and a country's missing years from historical trends, so the World value for such a year is partly Ember's estimate. Preliminary years in this vintage: 2023, 2024, 2025.

What it covers
- Geography
- World
- Basis
- Share of electricity generation, not of consumption: net imports are not included. Ember reports annual generation as gross generation where it can. Clean means renewables plus nuclear.
- Unit
- percent of electricity generation (%)
