Good News: A Bunch Of AI Data Centers In Limbo

Why it matters: The delay or cancellation of half of planned U.S. AI data centers this year directly impacts 241 GW of global capacity.
- CleanTechnica highlights that AI data centers are a major obstacle to cutting greenhouse gas emissions, often using dirty portable gas plants, keeping coal plants running, and increasing overall energy demand.
- Paul Kedrosky (per Edward Zitron) reported that new data center capacity additions halved in Q4 2025, with only 33% of 241 GW of disclosed capacity under active development.
- Sightline Climate analysts (interviewed by Bloomberg) confirm that only 6.3 GW of data centers planned for 2027 are under construction, compared to 21.5 GW announced, with even less progress for projects beyond 2028.
- Andrew Likens of Crusoe’s (per Bloomberg) identifies a critical bottleneck in electrical components like batteries, transformers, and circuit breakers, which, despite being less than 10% of construction cost, are essential and primarily manufactured abroad.
A significant slowdown is hitting the AI data center boom, with half of the U.S. capacity slated for this year delayed or canceled, and only a third of announced global capacity under active development. This unexpected bottleneck, primarily due to a shortage of critical electrical components manufactured abroad, offers a surprising reprieve for climate goals, as these centers often rely on fossil fuels and increase energy demand.
