“U.S. nuclear power plants contribute more than half of our carbon-free electricity, and President Biden is committed to keeping these plants active to reach our clean energy goals,” Energy Secretary Jennifer Granholm said in a statement. “We’re using every tool available to get this country powered by clean energy by 2035, and that includes prioritizing our existing nuclear fleet to allow for continued emissions-free electricity generation and economic stability for the communities leading this important work.”

A strong majority of states — about two-thirds — say nuclear, in one fashion or another, will help take the place of fossil fuels. A dozen U.S. commercial nuclear power reactors have closed in the past decade before their licenses expired, largely due to competition from cheaper natural gas, massive operating losses due to low electricity prices and escalating costs, or the cost of major repairs.
