OpenAI CEO Sam Altman has made specific claims about ChatGPT's resource consumption in response to growing concerns about artificial intelligence's environmental footprint. As AI technology becomes increasingly integrated into daily operations across industries, questions about its sustainability have intensified, prompting company leaders to address these concerns directly.
Water Consumption Claims Under Scrutiny
In his recent blog post titled The Gentle Singularity, Altman stated that an average ChatGPT query consumes approximately one-fifteenth of a teaspoon of water, equivalent to 0.000085 gallons. When scaled to ChatGPT's estimated one billion daily queries, this translates to roughly 85,000 gallons of water per day. While this figure represents only 0.0000026% of the United States' daily water consumption of 322 billion gallons, critics have raised concerns about the methodology behind these calculations.
Energy Usage Metrics Revealed
Beyond water consumption, Altman disclosed that each ChatGPT query uses about 0.34 watt-hours of energy. To put this in perspective, this amount equals what a conventional oven would consume in slightly over one second, or what a high-efficiency lightbulb would use over several minutes. These figures represent OpenAI's attempt to quantify and contextualize the environmental cost of AI interactions.

Missing Methodology Raises Questions
The absence of detailed methodology in Altman's claims has drawn skepticism from environmental experts and industry analysts. The calculations do not specify whether they include only direct server cooling costs or encompass the broader environmental impact of AI infrastructure, including hardware manufacturing, installation, and maintenance. This lack of transparency makes it difficult to verify the accuracy of the stated figures or understand their full scope.
Broader Environmental Concerns Persist
While water usage may appear minimal based on Altman's figures, energy consumption remains a significant concern for the AI industry. Current estimates suggest that artificial intelligence accounts for approximately one-fifth of all data center power consumption globally. This substantial energy demand has prompted Altman himself to pursue funding for fusion reactor development, acknowledging the power challenges posed by AI scaling.
Future Cost Predictions and Industry Impact
Altman predicts that as AI technology advances and becomes more efficient, the cost of generating artificial intelligence will eventually approach the basic cost of electricity required to run the hardware. He believes that massive scaling will drive down these costs, though critics argue that current resource consumption levels may be understated and that the environmental impact could be more significant than presented.
Long-term Perspective on AI Benefits
The debate extends beyond immediate environmental costs to consider potential long-term benefits. Some proponents argue that advanced AI systems could eventually help solve environmental problems by developing cleaner energy solutions and optimizing resource usage across various industries. However, until such benefits materialize, the focus remains on minimizing current environmental impacts while the technology continues to scale rapidly.
