Will global data-center electricity demand approach the IEA's projected 950 TWh in 2030?
The IEA's Key Questions on Energy and AI report, published 16 April 2026, estimates data centers used about 485 TWh in 2025 and projects roughly 950 TWh by 2030 in its central outlook. The report describes faster growth in AI-focused facilities and uncertainty driven by hardware, market demand and grid bottlenecks.

What cannot yet be concluded
Evidence limit: This is an IEA energy projection, not an observed 2030 outcome and not a Cortist probability forecast. Future annual statistics may revise definitions and baselines. Data-center power demand is broader than AI-only consumption and cannot be inferred directly from hypothetical company investment pledges.
Category: projection tracking. This is an external agency scenario. It is not a locked, scored Cortist forecast.
Dated evidence history
Central projection roughly 950 TWh data-center electricity demand in 2030.
Comparable measured electricity data should be used rather than rewriting the forecast.
