Data center electricity demand spans 700-1,700 TWh

7.8 significance by IEA Energy and AI Compute December 2035

Why does it matter?

The wide range shows how much AI adoption, efficiency, and energy bottlenecks could change the power buildout.

A Headwinds Case incorporates bottlenecks - including macroeconomic headwinds - in the uptake of AI and the buildout of energy infrastructure to power it. Our High Efficiency Case highlights the potential for even stronger gains in the efficiency of AI-related hardware and AI models. In this case, electricity demand from data centres is 20% lower in 2035 than in the Base Case. By 2035, the range of data centre electricity demand across our cases spans from 700 to 1 700 TWh.
