A new survey of Americans’ attitudes about energy by ecoAmerica, a Washington, D.C.–based environmental nonprofit, finds notable shifts in views on several energy sources, including nuclear energy, from 2018 to 2021.

The American Climate Perspectives Survey shows that national support for nuclear increased by 10 percentage points, from 49 percent to 59 percent. (The numbers reflect both strong and tepid backing.) Broken down by party affiliation, the survey shows Republican support holding steady at 64 percent, Independent support moving from 50 percent to 61 percent, and Democratic support rising, rather dramatically, from 37 percent to 60 percent.
