Tim Peake: AI’s Limitless Power Comes at a Hidden Environmental Cost

At the Goodwood Festival of Speed, astronaut Tim Peake raised concerns over the unchecked energy consumption behind artificial intelligence tools like ChatGPT—calling it “remarkable” that there are no limits on usage, despite the growing environmental impact.
Speaking inside the Future Lab exhibition in Chichester, surrounded by futuristic tech and AI-powered robotics, Peake highlighted the urgent need to address how energy-hungry these innovations have become.
“There’s no limit to how much people can use ChatGPT,” Peake told PA. “They can stream videos, generate avatars, and nobody is thinking about the energy or water required to cool the data centres behind it.”
Peake emphasized that an AI-powered search can consume 30% more energy than a traditional Google search. He added, “Maybe we need a reminder next to the search bar: Search responsibly.”
According to Business Energy UK, ChatGPT may be using around 39.98 million kWh per day—enough to charge over eight million smartphones. The Times also reported that sending a 100-word email using GPT-4 requires enough water to fill a 500ml bottle just for cooling purposes.
Despite these concerns, Peake remains optimistic about the future. He believes space-based data centres could provide a solution—clean, unlimited solar energy and zero-emission cooling in the vacuum of space.
Working with Axium Space, he revealed plans for two orbital data nodes launching later this year, aiming for cost parity with Earth-based cloud systems by the mid-2030s.
“Space might not solve everything,” Peake said, “but it holds many answers. Over half of our climate data already comes from orbit—it’s our planet’s pulse.”
Still, experts like Dr. Domenico Vicinanza of Anglia Ruskin University urge caution, citing the logistical challenges of powering and protecting tech in orbit.
The Future Lab featured cutting-edge exhibits, including Ameca, a hyper-realistic humanoid robot driven by ChatGPT. Peake noted, “Her non-verbal responses are astonishing—AI’s not just talking now, it’s learning to react like us too.”
While fascinated by AI’s potential, Peake warned against relying too heavily on it. “Does AI make it too easy? Do we still take pleasure in discovering things, or are we just reading answers?”
