Opposition to Nuclear Energy

In August 2021, the Green Party of the United States was a cosigner on a letter to the leadership of the U.S. Congress that categorized nuclear energy as “dirty” and “dangerous” and “part of the climate problem, not a solution.” ²

Nuclear power plants produce no carbon dioxide or other greenhouse gas emissions, and as of 2021 accounted for 19 percent of American electricity production—the largest source of zero carbon electricity in the United States. ³ An October 2018 proposal from The Nature Conservancy noted that zero-carbon nuclear plants produced 7.8 percent of total world energy output and recommended reducing carbon emissions by increasing nuclear capacity to 33 percent of total world energy output. ⁴
