U.S. states are positioning themselves to compete for newer, cheaper nuclear reactors being developed as communities and tech giants compete in a race for electricity. For some state officials, nuclear is a carbon-free source of electricity that helps them meet greenhouse gas reduction goals. Others see it as an always-on power source to replace an accelerating wave of retiring coal-fired power plants. Twenty-five states passed legislation to support advanced nuclear energy last year. This year lawmakers have introduced over 200 bills supportive of nuclear energy. The reactors have high-level federal support and utilities across the U.S. are working to incorporate the energy source into their portfolios.
