Electricity in September 2026: Demand Up 3.1% on September 2025

Demand in the 52 countries with data for both September 2026 and September 2025 was 1,979 TWh in September 2026, up 3.1% on September 2025. Those 52 countries cover 74% 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 45.2% of their generation in September 2026.

How This Month Is Measured

  • Coverage. 52 countries reported September 2026. 52 of them also have September 2025, and those 52 are the like for like set behind every figure above. Together they made up 74% 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.
