Opinion: No, nuclear power isn’t the ‘big bazooka’ climate fix you might think via CNN

Germany’s exit from nuclear power on April 15 doesn’t single it out as a quirky anomaly or black sheep in a world otherwise enthusiastically embracing nuclear energy.

Rather, it situates Germany firmly within the global mainstream: ever more countries are abandoning or scaling back their nuclear power programs, including the US.

Since a highpoint in the early 2000s, the number of operational nuclear reactors worldwide has fallen – from 438 to 411, according to this year’s World Nuclear Industry Status Report. (And that was before Germany’s move this week).

Nuclear power’s share of global electricity generation has now slid to its lowest point in four decades. While at the same time, renewable energy generation – clean tech like solar, wind, bioenergy and geothermal – has expanded by more than 30-fold.

Despite bipartisan backing, the US, the globe’s nuclear energy stronghold, has 12 fewer reactors operational than a decade ago – and none at all under construction.

In fact, when matched up against renewables as a source of energy that doesn’t emit carbon, nuclear power falls egregiously short.


The two reactors that will go online this year in the US state of Georgia racked up costs of more than $30 billon. But the Hinkley C plant in the UK takes the dubious prize of the priciest: currently $32 billion.

As for rollout time – critically important as the planet is racing against the clock to stop global warming – nuclear also occupies the doghouse. While authoritarian states such as China start up plants more quickly – though not nearly as quickly as they throw up giant wind and solar farms – in the West construction time is almost always vastly underestimated. Supposedly about ten years, though usually much longer.


None of these numbers or arguments, however, should obscure the original reason that Germany, as well fellow European countries Spain and Switzerland, chose to toss in nuclear power, to say nothing of many of the 163 countries that never went the way of spitting atoms for energy in the first place.

Nuclear fission remains an extremely dangerous and toxic means of energy generation. In addition to the meltdowns in Chernobyl, Ukraine (1986) and Fukushima, Japan (2011), according to the IAEA, there have been 31 serious incidents at nuclear power stations worldwide since 1952— including two in France and six in the United States.

Most recently, in November 2022 the Monticello Nuclear Generating Plant north of Minneapolis, Minnesota, leaked about 400,000 gallons of radioactive water into a nearby stream.

And nuclear waste remains a radioactive dilemma without a solution. There are currently more than 250,000 tonnes of spent fuel sitting on or near nuclear plant sites – waiting for permanent repository sites to be named and constructed. The problem since 1954: nobody but nobody wants it stored near their communities or water supplies.

Germany, and all of Europe, is building out renewable energy, smart grids, electric vehicles and energy storage facilities at breakneck pace to eliminate fossil fuels from its energy supply.

This is a clear-headed, evidence-based decision in contrast to the pipedream of a nuclear future.
