Full EV charge (~60 kWh) = 200,000 AI prompts
Full EV charge (~60 kWh) equals roughly 200,000 AI prompts on the electricity side: 60,000 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 200,000 prompts?
The math fits in three lines, using public, sourced values:
- 1.Full EV charge (~60 kWh): 60,000 Wh (US DOE/EPA : fueleconomy.gov (véhicules électriques))
- 2.1 text prompt: 0.3 Wh (published range: 0.24 to 0.4 Wh)
- 3.60,000 Wh ÷ 0.3 Wh ≈ 200,000 prompts
In other words, “Full EV charge (~60 kWh)” weighs as much as 200,000 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 “Full EV charge (~60 kWh)” is also roughly 6,667 times one generated image, or 3,000 times one reasoning prompt.
Convert your own usageWhere do these numbers come from?
The value we use for “Full EV charge (~60 kWh)” comes from “US DOE/EPA : fueleconomy.gov (véhicules électriques)”, 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.
