Electricity in October 2025: Demand Up 4.2% on October 2024

Demand in the 84 countries with data for both October 2025 and October 2024 was 2,270 TWh in October 2025, up 4.2% on October 2024. Those 84 countries cover 91% of world electricity demand (measured on 2025 demand), so this is a review of the reporting countries, not a world total. Low carbon sources supplied 45.1% of their generation in October 2025.

How This Month Is Measured

  • Coverage. 84 countries reported October 2025. 84 of them also have October 2024, and those 84 are the like for like set behind every figure above. Together they made up 91% of world demand in 2025. A month is published only when at least 10 countries and 60% of world demand are covered.
  • Not a world total. These sums cover the reporting countries only.
  • Carbon intensity. The figure for the group weights each country's monthly intensity by its generation; country rankings use Ember's own monthly intensity.
