With artificial intelligence (AI) expanding its reach and sophistication, the industry’s energy consumption has skyrocketed, presenting a paradox for a sector that also seeks to be a champion of sustainability. OpenAI’s Sam Altman, at the forefront of AI innovation with tools like ChatGPT, has offered a solution to the conundrum: nuclear fusion.
Altman’s vision, as reported, is that nuclear fusion, the reaction that fuels the stars and promises an abundance of clean energy, is the panacea for the AI industry’s burgeoning power requirements. “There’s no way to get there without a breakthrough; we need fusion,” Altman asserted in a January interview, also echoed in his conversation with podcaster Lex Fridman. His commitment to this belief is further underlined by his significant investments, running into hundreds of millions, in fusion technology.
The appeal of fusion is evident, as it potentially offers vast amounts of energy without the drawbacks of carbon pollution or long-lived nuclear waste. This seemingly perfect match for the AI industry’s needs has not yet materialized, and many experts are skeptical, pointing to the likelihood that fusion technology is decades away from being a commercially viable energy source.
The challenge, as Aneeqa Khan of the University of Manchester pointed out, is “recreating the conditions in the center of the sun on Earth,” a feat that might not be achieved until the latter half of this century. Khan’s perspective brings a dose of reality to the discussion, “Fusion is already too late to deal with the climate crisis,” emphasizing the need to leverage existing low-carbon technologies in the meantime.
AI’s energy demands are undeniably growing at an alarming rate, with the International Energy Agency estimating that electricity consumption from data centers, cryptocurrencies, and AI could double in the next two years. Altman’s suggestion of fusion as a future solution does not address the immediate concerns of this trajectory, which is on a collision course with sustainability goals.
Alex de Vries of Vrije Universiteit Amsterdam criticizes the industry’s reliance on such “wishful thinking,” advocating for a focus on current, actionable climate solutions rather than distant technological breakthroughs. The rapid growth of data centers in the U.S., expected to triple by 2030, according to a Boston Consulting Group analysis, adds urgency to this call for immediate action.
The reality is stark: AI is becoming more energy-intensive, not less, even as companies rush to integrate AI-driven solutions into various applications, further exacerbating energy requirements. The philosophy that “bigger is better when it comes to AI,” as de Vries notes, is fundamentally incompatible with sustainability, pushing companies toward vast, energy-hungry models.
Despite the push for more efficiency in data centers by companies like Google and Microsoft, history has shown that efficiency gains often lead to increased demand, rather than a net reduction in energy consumption. This, coupled with the political landscape, where initiatives like Sen. Ed Markey’s legislation for greater transparency in AI’s environmental impact struggle for bipartisan support, casts doubt on the sector’s near-term ability to reconcile its aspirations with environmental responsibilities.
OpenAI’s approach, with Altman at the helm, pinning hopes on nuclear fusion, could be seen as a microcosm of the broader tech industry’s quandary: the race for innovation and its unintended environmental consequences. As Michael Khoo from Friends of the Earth emphasizes, the question remains whether AI companies are truly addressing climate change today or using future promises as a smokescreen.
