AI's real bottleneck is electricity. Who will pay for it?

Big Tech is leaning on nuclear power to feed AI growth as data centers strain electricity supply and costs rise. Within a week, two of the three biggest cloud providers signed 20-year nuclear electricity contracts: Amazon agreed to take 690 megawatts from Constellation’s Calvert Cliffs plant in Maryland, including an extra 190 megawatts expected between 2030 and 2032; Google secured an agreement for 890 megawatts of additional nuclear capacity in the U.S. Constellation is investing more than $4.3 billion to upgrade 11 reactors across Illinois, Pennsylvania and New Jersey, without building new ones. The shift follows earlier declines after Three Mile Island, Chernobyl and Fukushima, and includes U.S. plans to restart plants supported by up to $4.4 billion in loans.
