Each of the five largest AI data centers matches 170,000 to 770,000 U.S. homes

What this chart asks

How many average U.S. homes use as much electricity as each of the largest AI data centers?

Why it is shown this way

• Points rather than stacked bars, so the full-load and half-load values are read as alternatives, not as parts that add up.
• The y axis starts at zero so distances to the 100,000-home reference line are honest.

Chart annotations

These markers provide relevant context for interpreting the chart. Their timing or position does not, by itself, establish causation.

Typical large data center: about 100,000 homes (CRS)

Threshold: 100000

Congressional Research Service, citing the IEA, says large data centers typically use as much energy as roughly 100,000 households.

Why this is marked: Reference level from the Congressional Research Service (R48583, June 2025) so readers can compare the largest AI sites with a typical large data center; not part of the dataset.

Largest operating AI data centers: power capacity and household-equivalent electricity, mid-2026

   Reliability: Academic. Epoch AI is an independent nonprofit research group that estimates data center power from satellite imagery, permits and public documents. It does not own or operate data centers.

Limitations

• IT power excludes cooling, so whole-facility use is higher than shown.
• Actual utilisation of each site is not public; full and half load bracket a plausible range rather than measure it.
• Capacity values are Epoch AI estimates dated May to August 2026.
