Google internally measured 0.24 Wh and 0.03 gCO2e per median prompt.

The Claim

Google Gemini's independently measured median prompt uses 0.24 watt-hours of electricity and produces approximately 0.03 grams of carbon-dioxide-equivalent emissions.

The Short Version

The figures accurately reproduce Google’s reported median of 0.24 Wh and approximately 0.03 gCO2e per Gemini prompt, but they were derived from Google’s internal instrumentation. No independent third party has verified or reproduced those measurements. Because the claim materially misstates the provenance and evidentiary status of otherwise accurate numbers, it is largely unsupported as worded.

Caveats

  • The figures are Google’s self-reported internal measurements, not independent measurements.
  • Repeated coverage of Google’s figures does not constitute independent verification or replication.
  • The carbon estimate depends on Google’s measurement boundaries and emissions-accounting methodology.
