In January 2026, a Virginia man received an electric bill for $281 — nearly triple the $100 he had paid the previous month. He had lived in the same house for 40 years. Nothing in his home had changed. What had changed was what surrounded it: Northern Virginia's "Data Center Alley," the largest concentration of AI data centers on the planet.
The question he started asking has become one of the defining consumer issues of 2026: are AI data centers genuinely responsible for rising electric bills? The honest answer is more nuanced than most headlines suggest. But the short version is: yes, partly, and the share is growing.
How Much Electricity Do AI Data Centers Actually Use?
The numbers are genuinely staggering. According to the IEA, data centers accounted for roughly half of all new electricity demand growth in the US last year — a share the agency expects to hold through 2030.
Total US data center energy demand is projected to nearly double between 2025 and 2028, jumping from 80 to 150 gigawatts. That 70-gigawatt addition is roughly equivalent to the entire annual electricity consumption of Spain added to the US grid in just three years.
