Is AI driving U.S. electricity demand?
“AI is driving the return of U.S. electricity-demand growth.”
Data centers are the largest new source of U.S. electricity demand and are projected to use 11.8% of national electricity by 2030 in LBNL’s reference case (range 9.5% to 15.3%, 2026), up from about 4.4% in 2023. EIA names data-center load as the cause of current load growth. National figures do not separate AI from ordinary cloud workloads facility by facility. Ruling: true.

How much electricity does AI use per prompt?
Google reports a median Gemini text prompt uses 0.24 Wh under its comprehensive methodology, which counts idle capacity, cooling and CPU overhead (2025). Sam Altman reports an average ChatGPT query uses about 0.34 Wh, roughly what a high-efficiency lightbulb draws in a couple of minutes (2025). Figures are not directly comparable across models or providers.
Why this grade
What the sources show
- 1
EIA says data-center electricity use is driving current growth in U.S. power demand.
- 2
LBNL’s detailed model attributes a large share of server growth to accelerated AI systems.
- 3
The 2030 reference case is 649 TWh, or 11.8% of U.S. electricity, with a 9.5%–15.3% range.
Attribution boundary
What would settle it
Facility-level reporting separates generative AI, other AI and conventional cloud workloads.
