Google’s Gemini AI assistant is being touted as one of the most sustainable large-scale AI systems today, with new data indicating that each prompt consumes just 0.26 milliliters of water and the electricity equivalent of running a TV for under nine seconds. The study claims emissions are only 0.03 grams of CO2 per query, showcasing a 33-fold energy efficiency improvement and a 44-fold reduction in carbon footprint. However, experts urge caution, noting that Google’s methodology may underestimate environmental costs, particularly by ignoring the significant water used in electricity generation. Critics emphasize the need for comprehensive data, arguing Google’s market-based emissions calculations may create an overly optimistic view. Additionally, the use of a “median prompt” for calculating resource consumption has been criticized for lacking transparency. Despite skepticism, Google remains committed to improving sustainability in AI technology and is open to future peer review of its findings.
