There’s long been a disconnect between concerns about the massive impact of AI data centres on electricity demand and claims by Sam Altman and others that the impact is really modest. Ed Zitron recently posted a summary of OpenAI’s 2025 accounts which helps to clarify things a bit.
In short, if you look at actual electricity demand needed for current AI use, it’s small. And that doesn’t change if demand grows at high but plausible rates. On the other hand, if you look at what is needed to justify the current valuations of AI and its competitors, the implied growth is staggering.
