Analysis: Global energy crisis drives rethink of nuclear power projects

Nuclear energy provides almost 20 percent of the U.S. electricity supply. Advocates have called for an expanded role for nuclear as an emissions-free fuel source. But the economics of building new reactors are daunting. In addition, lingering safety concerns are an institutionalized part of the calculation of nuclear regulation, and highly radioactive nuclear waste remains a can that public officials have been inclined to kick down the road. The Energy Information Administration projects a sharp decline in nuclear power generation over the next decade, as new nuclear plants — two are planned — are more than offset by anticipated retirements of several operating reactors.

The United States achieved net energy independence in 2020, but that has not insulated the nation from the roiling of energy markets in the wake of the Russian invasion of Ukraine. Europe has been a large consumer of Russian natural gas, and the effort to wean itself, with the help of the United States, has strained markets and endangered global efforts to address the climate crisis.
