As the Swedish election approaches, many can’t help but ask themselves what, exactly, they’re voting for when it comes to energy policy. Is it cheaper electricity, a greener future, or something completely different? Not even the politicians can seem to agree.
This past summer, over half of Sweden’s nuclear power was offline due to a cluster of unplanned reactor problems landing at the same time as dry conditions, sending electricity prices climbing at a historical rate. Meanwhile, right-wing politicians are promising nuclear power as the fix for expensive energy. This makes for a strange contradiction to sit with, as a country that attributed 30% of its energy use to nuclear power in 2025 and has 6 active nuclear reactors across 3 active plants is considering betting SEK 122 billion on its future, when it’s been a major cause of expensive energy.
To understand why this debate feels so fissile, we can go back to where it started in Sweden. During a 1980 referendum, following the Three Mile Island Accident in the U.S., voters were given three options for phasing nuclear power out; the question wasn’t if, rather, how fast. The “compromising”, gradual phase-out option won a narrow plurality of the vote, at 39.1%, and it was at this moment the Green Party (Miljöpartiet) was born. The party was founded by activists who felt none of the existing parties aligned with the seriousness of the anti-nuclear result. In other words, an entire political party exists today because of how confusing the discussion already was, even over 40 years ago.
Despite this, the phase-out was scrapped in 2009 and formally abandoned in 2023. Therefore, we can begin to wonder: If a party can be created out of the promise of finally resolving the conversation around nuclear power, and the question remains unanswered today, then maybe it’s less a radioactive policy debate and more an inert reflection of modern Swedish politics.
The nuclear debate doesn’t split neatly between left- and right-wing parties. Instead, the current right-leaning, Moderate-led government, with support from the Sweden Democrats, Christian Democrats and the Liberals, otherwise known as the Tidö parties, champions expansion. Yet the Social Democrats support nuclear power itself, so long as the state retains control over its regulation, while their own left partners, the Greens and Left Party, support its phaseout. Similarly to the Social Democrats with the left parties, the centre-to-centre-right Centre Party opposes state subsidies and financial support. In contrast, the Tidö parties promote expansion with state aid.
While voters are working off an outdated map, expecting the left to be anti-nuclear and the right to be pro-nuclear, the fallout runs deeper than party lines suggest. The current government replaced Sweden’s official energy target from “100% renewable” to “100% fossil-free” back in June 2023, a subtle yet deliberate rephrasing that allows nuclear power to contribute to the country’s climate goals for the first time in years. Although with this, even the terminology stops making sense.
Aside from the news, the politics, and the statistics, it may just be a question of education: Are we being taught too little in schools? Or is the problem that nuclear energy is taught as a history lesson? Though it is vital to acknowledge the events in Chernobyl and Hiroshima, the topic of nuclear energy is often confined to these historical events in schools, rather than emphasising the societal and scientific implications it carries today. While most schools cover the basic physics of fission, what is left largely unexplored is how it compares to fossil fuels, the management of nuclear waste, and the implications of large-scale development projects. Perhaps that’s the real fallout: The generations inheriting these decisions are left to navigate a global conversation with only half the picture.
Considering this multi-decade-long, multi-billion-kronor bet, whose shoulders it really lands on will be decided after September 13th. As millions of Swedes gather for the polls, the country’s nuclear future hangs in the balance and will depend on messy coalition math, not a clean nuclear-or-not referendum. It’s at this point that we realise the confusion that arises isn’t a bug in the debate of a greener future or cheaper electricity; instead, it is the debate.
