Three Mile Island Went From Cautionary Tale to AI Power Plant. The Public Hasn't Caught Up.

The {{entity:trump|Trump}} administration just loaned $1 billion to restart Three Mile Island — the plant that became America's shorthand for nuclear catastrophe — and called it the "poster child" of its energy and AI agenda. {{entity:microsoft|Microsoft}} has a deal to buy the power. {{entity:meta|Meta}} signed a separate 20-year nuclear contract with Constellation Energy the same week. {{entity:google|Google}} is pursuing an Iowa plant restart through a NextEra partnership. The speed of this buildout is striking: in roughly eighteen months, nuclear power has gone from an embarrassing legacy liability to a bidding war among the three largest technology companies on earth. News coverage has treated this almost entirely as a triumph — a clean-energy pivot, a grid modernization story, an investor opportunity. The headline count on Three Mile Island alone ran into the dozens this week, and the tone across outlets from Reuters to Fox News converged around the same framing: AI's power hunger is driving a nuclear renaissance, and that's probably good. The story {{story:three-mile-island-went-cautionary-tale-ai-power-cbe7|covered here}} noted that the public hasn't caught up to this rebranding yet, and the Bluesky reaction suggests that gap is real. Where news leans confidently optimistic, Bluesky leans skeptical — not because the platform is reflexively anti-nuclear, but because the argument being made requires trusting that the same companies whose data centers are causing the energy crisis are now the right entities to solve it. The energy consumption question crystallized fast this week. A post from @dlature, replying to what appears to be an ongoing thread about data center infrastructure, laid out the trajectory bluntly: AI's demands could account for roughly 12 percent of U.S. electricity consumption by 2028, a load currently being met in part by fossil fuels, actively slowing the clean energy transition. The post earned modest engagement but landed in a conversation that was already shifting — "energy consumption" went from nearly absent in this beat's vocabulary to appearing in roughly a third of recent posts. That's not a gradual trend; it's a phrase that arrived all at once, which usually means something structural changed, not just the volume. The {{story:data-centers-more-double-their-energy-draw-2035-x-e1cb|projection that data centers could more than double their energy draw by 2035}} is gaining traction as a reference point, and the question of who pays — ratepayers, the grid, future climate commitments — is now the central argument. The more interesting friction, though, isn't between optimists and pessimists — it's about what environmental concern is actually measuring. A Bluesky user this week described going directly to a scientist who works in water regulation and quality, expecting alarm about AI's water cooling demands. The scientist's response reframed the conversation: agriculture abuses were her primary concern, not data centers. The post got 21 likes — small, but the engagement pattern was clarifying. It wasn't shared as reassurance. It was shared as a calibration note, a reminder that the water-and-AI discourse may be absorbing anxiety that belongs elsewhere. On the other side, someone on Bluesky pushed back on AI water usage figures being circulated as inaccurate, pointing out that cooling systems have improved significantly over the past two years. These two posts, taken together, describe a community that's genuinely trying to reason about the environmental footprint of AI rather than perform concern — which makes the current conversation more interesting than the standard pessimism-versus-boosterism frame suggests. What the nuclear buildout actually resolves is the narrowest version of the problem: it addresses where the electrons come from, without touching how many electrons get used, who authorized the demand, or what climate commitments the tech companies quietly abandoned to get here. {{story:corporate-climate-pledges-dying-west-virginia-af64|Microsoft's West Virginia data center math}} already made this visible — the gap between corporate net-zero pledges and actual grid behavior is where the real argument lives, and the Three Mile Island deal doesn't close it. It just makes the demand legible. The Energy Secretary calling the restart a delivery on Trump administration promises signals that the political framing of this moment is about American energy dominance, not emissions reduction. The companies signing these nuclear deals get to say they're running on clean power. The harder accounting — what they're replacing, what's now on the margin, what the grid looks like in 2035 — stays off the press release.
