Fact Check: Do AI centers use a lot of electricity?
“Do AI centers use a lot of electricity?”
Summary
AI data centers draw a substantial share of electricity, accounting for roughly 10‑20% of total data‑center energy use in the United States and comparable to the power needs of tens of thousands of households. Projections indicate AI‑related workloads could represent up to about one‑fifth of global electricity demand by 2030, confirming that they use a lot of electricity.

It sees global electricity demand from data centres in 2035 that is around 45% higher than in the Base Case, exceeding the 1 700 TWh mark and reaching around 4.4% of global electricity demand. The High Efficiency Case shares similar constraints and drivers with the Base Case, but assumes stronger progress on energy efficiency in software, hardware and infrastructure. As a result, the same level of demand for digital services and AI is met with a reduced electricity consumption footprint.
