Americans want nuclear power now more than ever.

Support has surged to new highs, giving President Donald Trump a boost in his goal of expanding nuclear power-generating technology and building homegrown energy plants to fuel data centers.

In a new poll shared with Washington Secrets, 69% of registered voters backed Trump’s plan, more than twice the 29% that opposed it.

The survey, conducted by CRC Research for the 85 Fund, a conservative advocacy group, also showed little concern about the safety of nuclear power plants.

Following the 1979 crisis at the Three Mile Island plant near Harrisburg, Pennsylvania, support for nuclear energy plummeted, ending the country’s goal for many more plants. But in the new survey, a majority not only said it is safe but even more backed the conversion of used nuclear waste to power new plants.

At the just-ended Climate Week NYC 2025 conference, sessions talked up nuclear power as a renewable energy source, though the issue continues to divide Democrats and liberals.

New York Gov. Kathy Hochul (D) expressed support for nuclear power plants in her state prior to the conference, but did not speak at it. The Democrat has, however, talked with Trump about building out the nuclear power grid in New York, which he supports.

Some pro-nuclear advocates drove a truck around the conference site with a video of Hochul wearing a Trump-esque red hat that read, “Make Nuclear Great Again.”

Polls have shown growing support for nuclear power in recent years. A Gallup survey from last year put support at 56%.

Support could also be jumping because electricity prices are growing, in part to help fuel data centers, especially those built for artificial intelligence advances.

The key highlights in the survey:

— By 69% to 23%, voters support “investing more in developing nuclear energy to meet surging demand to keep energy prices low.”

— By 63% to 22%, voters support “a plan to convert old, used fuel — currently treated as nuclear waste and stored at great expense — to new nuclear energy to affordably power artificial intelligence (AI) data centers and millions of American homes.”

— Voters 51% to 39% believe “nuclear energy has proven to be safe and affordable in other countries and producing more affordable energy here would benefit American communities.”

The country has fewer than 100 nuclear power plants, most built in the 1970s. The oldest is in New York, Nine Mile Point-1, in Scriba. It started in November 1969.
