The long view
Nuclear Has Changed. Will the U.S. Change with It?
Fueled by artificial intelligence, cloud service providers, and ambitious new climate regulations, U.S. demand for carbon-free electricity is on the rise. In response, analysts and lawmakers are taking a fresh look at a controversial energy source: nuclear power.
Exploring the New Nuclear Energy Landscape
In the last few years, the U.S. has seen a resurgence of interest in nuclear energy and its potential for helping meet the nation’s growing demands for clean electricity and energy security. Meanwhile, nuclear energy technologies themselves have advanced, opening up new possibilities for their use.
