As artificial intelligence accelerates, a growing number of educators and citizens are pushing back against its adoption, citing the technology's massive energy consumption as morally indefensible. This editorial challenges that view, arguing that measuring AI solely by its current carbon footprint is a dangerous myopia that ignores its potential to solve the very environmental crises we fear. By examining AI’s critical role in unlocking fusion energy, revolutionizing battery storage, and accelerating life-saving medical breakthroughs, this piece reframes the "energy cost" as a necessary investment in human survival. It further explores the geopolitical risks of "opting out" and highlights emerging solutions—such as orbital data centers—that promise to decouple high-performance compute from terrestrial resources. Ultimately, this article posits that the true moral failure lies not in using AI, but in refusing to steward its potential for the greater good.
