AI query electricity use is smaller than most everyday activities
A new Our World in Data visualization argues that a typical ChatGPT query uses about 0.3 Wh, roughly the same as running an LED bulb for just under 2 minutes.
- Long, very high-effort prompts can use more energy, but still remain within the range of ordinary daily activities.
- The post notes that heavy personal use could make AI a noticeable part of someone’s electricity bill, though only if used a lot.
- At company scale, the cumulative load can matter for grid planning even if the per-query cost is small.
