The IEA's Energy and AI special report projects that global data centre electricity demand will more than double by 2030 to around 945 TWh, slightly more than Japan's current consumption.

### Background On 10 April 2025, the International Energy Agency (IEA) publishes its special report **Energy and AI**, which the agency describes as the most comprehensive data-driven global analysis to date on the links between AI and energy. It projects that global data centre electricity demand will **more than double by 2030 to around 945 TWh**, slightly more than Japan's entire electricity consumption today. AI is the main driver: demand from AI-optimised data centres is projected to more than quadruple by 2030. ### Key facts - Projection: about 945 TWh of data centre electricity demand in 2030, more than double today's. - Driver: demand from AI-optimised data centres more than quadruples by 2030. - United States: data centres would account for almost half of electricity demand growth by 2030; the US economy would use more electricity to process data than to make energy-intensive goods. - Advanced economies: more than 20% of electricity demand growth by 2030. - Energy sources: a wide range, with renewables and natural gas leading, according to the IEA. ### Why it matters The report makes electricity the central constraint of AI and serves as a reference for regulators, providers and customers. It invites IT departments to build energy cost and availability into their capacity scenarios, and to question providers on energy efficiency and supply. The projections keep a high uncertainty, flagged by the IEA itself. ### Takeaway Data centre electricity demand should more than double by 2030, with AI as the first driver.
