1 h of PC gaming = 1,333 AI prompts
1 h of PC gaming equals roughly 1,333 AI prompts on the electricity side: 400 Wh, while an average text prompt weighs just 0.3 Wh. The math, the source and detailed equivalents are right below, with public, verifiable numbers.

The electricity of a prompt covers inference: the work the model does in the data center while answering, cooling included. It does not include model training or server manufacturing. The everyday action, meanwhile, is measured at the plug, so the comparison is one use against another use.
Why 1,333 prompts?
The math fits in three lines, using public, sourced values:
- 1.1 h of PC gaming: 400 Wh (ADEME : consommation des appareils ménagers)
- 2.1 text prompt: 0.3 Wh (published range: 0.24 to 0.4 Wh)
- 3.400 Wh ÷ 0.3 Wh ≈ 1,333 prompts
In other words, “1 h of PC gaming” weighs as much as 1,333 questions asked to a generative AI. It is an order of magnitude, not a to-the-decimal measurement: sources publish ranges, and we use a median value, explained in our methodology.
What about a generated image or a reasoning prompt?
Not every AI use weighs the same. A generated image costs about 9 Wh and a “reasoning” prompt about 20 Wh, versus 0.3 Wh for a simple text prompt. So “1 h of PC gaming” is also roughly 44 times one generated image, or 20 times one reasoning prompt.
Convert your own usageWhere do these numbers come from?
The value we use for “1 h of PC gaming” comes from “ADEME : consommation des appareils ménagers”, referenced like all our data on the Sources page. No number on this page is made up: every value can be traced back to a public document.
On the prompt side, published values range from 0.24 to 0.4 Wh: Google and OpenAI have shared their own figures, and the research institute Epoch AI produced an independent estimate. We use 0.3 Wh.
