Notes on individual values
- Partly Ember's estimate: the file has no 2023 demand for 1 of the 209 countries and economies with demand 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 demand for 15 of the 209 countries and economies with demand 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 demand for 116 of the 209 countries and economies with demand 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 2026-10-19 (Ember gives no version label, so that date is the vintage), and kept Area 'World', Electricity source 'Demand', column 'Generation (TWh)'.
Code: pipeline/src/envdash/transforms/energy/ember_demand.py · code sha256 62080a6f510a4186… · inputs 91d30fb170da… 67c5eaac3bfb…
Checked that World demand equals World total generation (the world has no net imports) in every year, to within the rounding of the printed values.

Marked a year preliminary, with a note giving the count, when the file has no Demand 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 found on pages 10, 12) says it estimates the latest annual values from monthly data and a country's missing years from historical trends. Preliminary years in this vintage: 2023, 2024, 2025.

What it covers
- Geography
- World
- Basis
- Electricity demand as Ember publishes it for the world, which equals the world's total electricity generation in every year of the file (checked at each build). Ember reports generation as gross generation where it can. The latest years are partly Ember's estimates (marked preliminary).
- Unit
- terawatt-hours per year (TWh)
