The global figure of record: 415 TWh of data centre electricity in 2024

The International Energy Agency report Energy and AI, published 10 April 2025, states that data centres accounted for around 1.5 percent of the world's electricity consumption in 2024, or 415 terawatt hours, and that data centre electricity consumption is set to more than double to around 945 terawatt hours by 2030.

  • Data centres accounted for around 1.5 percent of world electricity consumption in 2024, or 415 TWh.
  • The agency's base case has data centre electricity consumption more than doubling to around 945 TWh by 2030.
  • The 945 TWh number is the agency's own projection published in April 2025, not a measurement.
  • The 2024 figure is global and covers all data centres, not AI workloads alone.

What it changes

For an operator, a utility or a community

An operator answering the question of how much of the world's power AI uses should quote this figure and the year, and should say plainly that the larger number is a projection. A utility can anchor a load forecast argument in a source no party can call partisan. A community should check whether a local claim used the 2024 measurement or the 2030 projection, because they are six years and one assumption apart.
