Google Defends Gemini AI Efficiency Amidst Environmental Concerns
Google says its Gemini AI uses very little water and electricity, like a few drops of water and running a TV for a few seconds per question.
It claims to have greatly improved efficiency.
However, some experts disagree, saying Google doesn't include all the water and energy used, such as from the power plants supplying energy.
They are worried about how the numbers are calculated and if they tell the whole story about how AI affects the environment.
Google claims Gemini AI prompts use minimal water and electricity, with low CO2 emissions.
The company reports a 33-fold energy efficiency improvement and 44-fold carbon footprint reduction.
Independent researchers express concerns about Google's methodology and data omissions.
Critics highlight the exclusion of indirect water usage from power generation and location-based emissions.
Discrepancies exist between Google's findings and previous estimates of AI environmental impact.
- Who
- Google, including Amin Vahdat and Jeff Dean, and independent researchers like Shaolei Ren.
- What
- Google released data on the environmental impact of its Gemini AI models, claiming high efficiency in water and electricity use.
- When
- The data was recently published in a new company study.
- Where
- Google's data centers.
- Why
- Google aims to demonstrate AI's sustainability and promote transparency, while some researchers urge caution.

Google's Stance
Google emphasizes Gemini AI's efficiency and minimal environmental impact.
Critic's Stance
Critics argue that Google's methodology downplays the full environmental costs of AI, including indirect water usage and emissions.
- Water usage per Gemini query
- 0.26 milliliters
- Energy usage per Gemini query
- Equivalent to nine seconds of TV use
- Carbon dioxide equivalent per query
- 0.03 grams
- Efficiency gain (past year)
- 33x (energy), 44x (carbon footprint)
