US Data Centers Projected to Use One‑Fifth of National Electricity by 2035

A BloombergNEF analysis indicates that the rapid expansion of artificial‑intelligence workloads will drive U.S. data‑center electricity consumption to about 20% of the nation’s total power generation by 2035, roughly four times current levels. The total capacity of these facilities is expected to approach 200 GW, with half dedicated to training and inference for AI models. This surge is already pressuring regional grids, especially from Virginia to Illinois, where utilities have temporarily halted new connections and reported price spikes of up to 76%.

The broader context mirrors the International Energy Agency’s mid‑year outlook, which projects global electricity demand to rise 3‑4% annually through 2027, driven by electric vehicles, data‑center growth, and cooling needs. While the U.S. faces the most immediate strain, the trend signals a worldwide increase in power requirements for AI‑intensive computing.

Analysts warn that without substantial grid upgrades and new capacity, the escalating demand could undermine electricity reliability and drive higher costs for consumers and industry alike.
