IEA Energy and AI analysis

International Energy Agency analysis estimating data centre electricity use now and in its base case to 2030.

Where it sits

It is a neutral reference for how much power data centres draw and why grid integration is a limiting factor.

Constraint

The IEA notes data centres cluster in specific locations, which can make grid integration harder, and that energy infrastructure takes longer to build than data centres (IEA).

What we checked

• The IEA estimates data centres used around 415 TWh in 2024, about 1.5 percent of global electricity. (source)
• Its base case reaches around 945 TWh by 2030, just under 3 percent of global electricity. (source)
