Sam Altman Says the Energy Needed for an Average ChatGPT Query Can Power a Lightbulb for a Few Minutes
- OpenAI CEO Sam Altman revealed that each ChatGPT interaction consumes roughly 0.34 watt-hours of energy, sufficient to keep a lightbulb illuminated for several minutes.
- Altman shared this information in a February blog post amid rising public scrutiny over AI's environmental and operational costs.
- He also revealed each query consumes roughly 0.000085 gallons of water, or about one-fifteenth of a teaspoon, while AI costs are dropping tenfold annually.
- Altman predicted that the expense associated with intelligence will ultimately align closely with the price of electricity, and he envisions a future in the 2030s where both energy and intelligence become extremely plentiful.
- This suggests AI resource usage per query is minimal, but overall energy demand may rise with AI adoption, increasing the need for sustainable energy solutions.
