So some Gemini prompts use rather more power than this: Dean provides the instance of feeding dozens of books into Gemini and asking it to provide an in depth synopsis of their content material. “That’s the form of factor that can in all probability take extra power than the median immediate,” Dean says. Utilizing a reasoning mannequin may even have the next related power demand as a result of these fashions take extra steps earlier than producing a solution.
This report was additionally strictly restricted to textual content prompts, so it doesn’t symbolize what’s wanted to generate a picture or a video. (Different analyses, together with one in MIT Technology Review’s Power Hungry series earlier this 12 months, present that these duties can require rather more power.)
The report additionally finds that the full power used to subject a Gemini question has fallen dramatically over time. The median Gemini immediate used 33 occasions extra power in Might 2024 than it did in Might 2025, based on Google. The corporate factors to developments in its fashions and different software program optimizations for the improvements.
Google additionally estimates the greenhouse gasoline emissions related to the median immediate, which they put at 0.03 grams of carbon dioxide. To get to this quantity, the corporate multiplied the full power used to reply to a immediate by the typical emissions per unit of electrical energy.
Reasonably than utilizing an emissions estimate primarily based on the US grid common, or the typical of the grids the place Google operates, the corporate as an alternative makes use of a market-based estimate, which takes into consideration electrical energy purchases that the corporate makes from clear power tasks. The corporate has signed agreements to purchase over 22 gigawatts of energy from sources together with photo voltaic, wind, geothermal, and superior nuclear tasks since 2010. Due to these purchases, Google’s emissions per unit of electrical energy on paper are roughly one-third of these on the typical grid the place it operates.
AI information facilities additionally devour water for cooling, and Google estimates that every immediate consumes 0.26 milliliters of water, or about 5 drops.
The objective of this work was to offer customers a window into the power use of their interactions with AI, Dean says.
“Persons are utilizing [AI tools] for all types of issues, they usually shouldn’t have main issues in regards to the power utilization or the water utilization of Gemini fashions, as a result of in our precise measurements, what we have been in a position to present was that it’s really equal to stuff you do with out even fascinated about it every day,” he says, “like watching a couple of seconds of TV or consuming 5 drops of water.”
