Nuclear power is clean and safe. Why aren't we using more of it?
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.
Aquick 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.
"Any energy policy has pros and cons, and we feel, after putting a lot of scrutiny on it, that the pros outweigh the cons of nuclear energy," said Dawson, a grassroots campaigner at Nuclear New York.
It's a contentious statement. Many scientists and environmentalists say nuclear power is prohibitively dangerous and expensive, that plants take too long to build. "Better to expand renewable energy or energy saving, that is a better use of money in terms of climate change mitigation," says Jusen Asuka, director at the Institute for Global Environmental Strategies in Kanagawa, Japan.
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.
This second camp mourns the decline of nuclear power, which has steepened since the 2011 meltdown at Fukushima. The International Energy Agency estimates the developed world is on track to lose 66% of its current nuclear capacity by 2040. In the US, where nuclear power produces nearly 40% of the country's low-carbon power, 11 reactors have been decommissioned since 2013 -- and nine more will soon join them.
The most recent retirement was Indian Point Energy Center, which formerly produced 25% of the electricity used by 10 million New Yorkers. One reactor was shut last year and the second followed on April 30. The result? Higher emissions as the electricity gap is filled by natural gas.
"The whole goal that everybody's talking about is to increase zero emission electricity, yet they are shutting down the source of the vast majority of zero emission electricity," said Dawson. "So this drives us insane."
