Electricity in December 2025: Demand Up 2.8% on December 2024

Demand in the 83 countries with data for both December 2025 and December 2024 was 2,435 TWh in December 2025, up 2.8% on December 2024. Those 83 countries cover 90% 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 43.2% of their generation in December 2025.

How This Month Is Measured

  • Coverage. 83 countries reported December 2025. 83 of them also have December 2024, and those 83 are the like for like set behind every figure above. Together they made up 90% 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.
