Nuclear energy is far safer than its reputation implies. It's also clean and reliable -- yet power plants are being phased out around the world. //

A quick thought experiment. What would the climate change debate look like if all humanity had was fossil fuels and renewables -- and then today an engineering visionary revealed a new invention: nuclear energy. That's the hypothetical posed to me by Dietmar Detering, a German entrepreneur living in New York.

"I'm sure we'd develop the hell out of it," he said, before sighing. "We're looking at a different world right now." //

Detering thinks nuclear energy could be the key to solving the climate crisis. A former member of Germany's Green Party, Detering now spends his spare time as co-chair of the Nuclear New York advocacy group. He's part of a wave of environmentalists campaigning for more nuclear energy.

Though the word evokes images of landscapes pulverized by atomic calamity -- Hiroshima, Chernobyl, Fukushima -- proponents like Detering and his colleague Eric Dawson point out that nuclear power produces huge amounts of electricity while emitting next to no carbon.

This separates it from fossil fuels, which are consistent but dirty, and renewables, which are clean but weather dependent. Contrary to their apocalyptic reputation, nuclear power plants are relatively safe. Coal power is estimated to kill around 350 times as many people per terawatt-hour of energy produced, mostly from air pollution, compared to nuclear power. //

But many scientists and experts believe nuclear power is necessary to achieve carbon neutrality by 2050. "Anyone seriously interested in preventing dangerous levels of global warming should be advocating nuclear power," wrote James Hansen, a former NASA scientist credited with raising awareness of global warming in the late '80s, in a 2019 column. //

In the public imagination, nuclear power presages disaster. But the numbers tell a different story. Estimates of deaths from nuclear incidents range from less than 10,000 to around 1 million. As you can infer, it's a highly contested number -- but in either case dwarfed by the death toll from fossil fuel pollution. Around 8.7 million premature deaths were caused by fossil fuel pollution in 2018 alone, according to a February Harvard study.
