Sam Altman Defends AI Energy Use, Urges Greener Solutions
OpenAI CEO Sam Altman, speaking at an event hosted by The Indian Express during an AI summit in India, rejected claims that AI services use large amounts of water, calling such claims "totally fake" and linking past concerns to older evaporative-cooling practices in data centers. He acknowledged that total energy consumption from widespread AI use is a legitimate concern and urged a faster transition to low-carbon power sources like nuclear, wind and solar. Altman disputed specific claims that a single ChatGPT query equals 1.5 iPhone battery charges and argued that comparisons should account for the energy cost to train systems versus the lifetime energy investment in human learning, suggesting AI may already be competitive on energy efficiency per inference once trained. The article notes there is no legal requirement for tech firms to disclose energy or water usage.
Comments from the OpenAI CEO on AI energy and water use contribute to public and industry debate about environmental impact and power sourcing but do not constitute a policy or technical change.

Sam Altman: AI's Energy Debate Misguided, Focus on Total Impact
OpenAI CEO Sam Altman defended AI’s resource demands at the India AI Impact Summit in New Delhi on Feb. 19, 2026, calling online claims that ChatGPT uses gallons of water per query "completely untrue." Altman acknowledged that total energy consumption from growing AI use is a legitimate concern and urged faster deployment of low‑carbon power such as nuclear, wind and solar. He argued that inference (post‑training model use) is energy‑efficient when compared to a human answering the same question. The comments referenced broader industry data: a Xylem/Global Water Intelligence projection that water drawn for cooling could more than triple in 25 years, and an IMF finding that 2023 data‑center electricity use was comparable to a large European country. Altman’s remarks prompted pushback from figures including Zoho co‑founder Sridhar Vembu and sparked online debate.
What AI Really Costs the Planet
This feature examines the environmental footprint of modern AI, arguing that visible interfaces hide substantial energy, water and materials costs. It compiles recent studies and estimates: data centres already consume a material share of US electricity, training and deploying large models requires large energy and cooling inputs, and manufacturing and rapid turnover of AI-specific GPUs add to carbon emissions and e-waste. The piece highlights uneven geographic impacts (data-centre growth stressing local grids and water supplies), a transparency gap in corporate reporting, nascent regulatory moves in the US and EU, and industry bets on nuclear power as a long-term supply solution. It also discusses psychological effects (eco-anxiety) and behavioral levers like carbon labelling and intentional AI usage as partial mitigations, while noting efficiency improvements in inference that coexist with rapidly rising aggregate demand.
Al Gore: AI Data Center Emissions Less Scary Than Industry Warnings
In an interview with TechCrunch, Al Gore and Lila Preston of Generation Investment Management discussed AI data center emissions and AI risks. Gore argued that AI data center emissions are only a fraction of global emissions from uncovered landfills and that air conditioning consumes more electricity than the entire EU. He expressed concern about hyperscalers using methane turbines but preferred renewable energy and batteries. He believes public backlash is driven by fears of job losses and AI threats, citing warnings from OpenAI and Anthropic leaders. He takes AI leaders' warnings seriously, noting recent incidents of AI models escaping confinement and deceptive behavior. Gore also cited a study projecting AI could reduce global emissions by 6-9% annually. Preston highlighted Generation's investments in grid resilience and renewable integration, including Volue and Gridware. The interview also referenced Generation's annual Sustainability Trends Report and global clean energy investment trends.
