OpenAI CEO Defends AI Energy Consumption

Altman says concerns about ChatGPT's water and energy usage are "totally fake" and "insane"

Feb. 21, 2026 at 9:38pm

OpenAI CEO Sam Altman addressed concerns about the environmental impact of AI, dismissing claims about ChatGPT's water usage as "totally fake" and "insane." While acknowledging the need to address AI's total energy consumption, Altman argued that the energy required to train a human is far greater than the energy used by an AI model to answer a query.

Why it matters

As AI systems like ChatGPT become more widely used, there is growing scrutiny around their environmental impact, particularly in terms of energy and water consumption. Altman's comments aim to push back on what he sees as unfair comparisons and misinformation about the energy efficiency of AI versus humans.

The details

Altman said concerns about ChatGPT's water usage are "totally fake" and "no connection to reality." He acknowledged the need to address AI's total energy consumption, but argued that the energy required to train a human is far greater than the energy used by an AI model to answer a query. Altman also complained that many discussions about ChatGPT's energy usage are "unfair" when they focus on the energy it takes to train an AI model rather than the energy efficiency of a single query.

  • Altman made these comments during an event hosted by The Indian Express in India, where he was attending a major AI summit.

What they’re saying

“It also takes a lot of energy to train a human.”

— Sam Altman, CEO, OpenAI (The Indian Express)

“Now that we don't do that, you see these things on the internet where, 'Don't use ChatGPT, it's 17 gallons of water for each query' or whatever. This is completely untrue, totally insane, no connection to reality.”

— Sam Altman, CEO, OpenAI (The Indian Express)

What’s next

Altman's comments come as researchers continue to study the environmental impact of AI systems, with a focus on energy and water usage. As AI becomes more prevalent, there may be increased pressure on tech companies to be more transparent about their energy and resource consumption.

The takeaway

Altman's defense of AI's energy efficiency highlights the ongoing debate around the environmental impact of emerging technologies. While acknowledging the need to address AI's total energy use, he argues that the energy required to train a human is far greater than that used by an AI model, challenging what he sees as unfair comparisons.
