US unveils nuclear expansion plan to meet growing energy demand

The U.S. government announced a framework to significantly expand nuclear energy to meet increasing electricity demand driven by AI data centers, electric vehicles and new manufacturing.

Andrew Freedman reports for Axios.


In short:

  • The U.S. plans to add 15 gigawatts of nuclear power by 2035, with a goal of reaching 200 gigawatts by 2050.
  • New nuclear plants may include large, small modular and microreactors rather than traditional large stations.
  • Major companies like Microsoft, Google and Amazon are pursuing nuclear energy deals to power data centers.

Why this matters:

Rising electricity demand and climate concerns make nuclear power an option for reliable, carbon-free energy. Expanding nuclear capacity, especially with modular reactors, could provide essential support for energy-intensive industries while aiding in climate goals. However, increased reliance on nuclear power also raises health and safety concerns.
