AIの汚い秘密 ― 3,300万トンのCO2がエージェント型知能の代価に
NvidiaとAmazonはAIを支えるため、炭素集約型の電力インフラに数十億ドルを投資している。Amazonが支援する発電所は年間3,300万トンのCO2を排出する可能性があり、AIのエネルギー需要が気候目標からの後退を迫っていることを示している。
nvidia plans to invest $2 billion for a 20% stake in lancium, which has 4gw of power under contract and is developing sites for 15gw more, while amazon is building a massive gas-fired power plant in pecos county to support its data centers. the amazon facility's 35 turbines could generate 7.65gw of power but emit up to 33 million tons of co2 annually, potentially making it the nation's dirtiest plant. these investments highlight that the massive energy requirements of agentic ai are now directly conflicting with decarbonization timelines. this shift forces the industry to confront the reality that scaling current ai models may require locking in fossil fuel infrastructure for decades.
