...AND CHEAPER...:

Like wind and solar power, nuclear generates electricity without burning fossil fuels. But the mining and manufacturing processes behind wind turbine blades, solar panels, and uranium pellets do have carbon footprints. Considering this, an analysis by Our World in Data concluded that nuclear generates 3 tons of greenhouse gasses per terra-watt hour (TWh) of electricity produced, while wind generates 4, and solar 5.

Then there's safety: The same analysis estimated the fatality rate for nuclear at 0.07 deaths per TWh, higher than wind, 0.04, and solar, 0.02. But lower than natural gas, estimated at 2.8 deaths per TWh, and much lower than coal power, at 24.6. Though risks can be complicated, and estimating deaths can often be speculative, there's now plenty of evidence that, with climate impacts and other elements factored in, nuclear is way safer than many alternatives.

Yet, in a poll conducted by The Economist and YouGov, a market research company, shortly after Russia invaded Ukraine, 47 percent of Americans said they didn't think nuclear power plants were safe.

To be clear: nuclear power has real downsides. Uranium mining is destructive and toxic. Spent fuel has to be carefully and expensively sealed and stored. And, however small, there is the risk of radiation releases and meltdowns. The small amount of radiation that escaped from Three Mile Island -- long dismissed as harmless by experts and the government -- has led to localized increases in several kinds of cancer, according to a 2022 paper published in the journal Risks Hazards Crisis Public Policy. Wind and solar power may well be cheaper and less risky. But that doesn't mean nuclear power is as bad as people think it is.

Rather than actual statistical risk, the majority of citizens rely on risk perception, according to Paul Slovic, a professor at the University of Oregon and an expert on risk and decision making. In a 1987 article published in the journal Science, Slovic writes, "For these people, experience with hazards tends to come from the news media." He cites a study from 1980, in which various groups were asked to rank 30 activities and technologies in order of risk. College students and members of the League of Women Voters assigned number 1, the highest risk, to nuclear power, ahead of hand guns and smoking. Experts ranked nuclear power at 20; motor vehicles at 1, smoking at 2, and hand guns at 4.

Slovic blamed this massive gap on "extensive unfavorable media coverage," "deep anxieties," and a "strong association between nuclear power and the proliferation and use of nuclear weapons."
