Power supply emerges as biggest bottleneck to AI expansion as Altman infrastructure warning revisited

Power constraints are again in focus as a key bottleneck that could hinder the development of more powerful AI. As AI models advance, demand for data centres and computing resources is surging, but power generation and transmission infrastructure is harder to expand at the same pace. TechRadar revisited past remarks by OpenAI CEO Sam Altman, who warned that AI would consume far more energy than expected and called for breakthroughs including fusion and cheaper solar and storage.
