The Reemergence of Nuclear Power

When I reviewed the Nuclear Stations Map in August, I was surprised to see that, a little over a decade after the Fukushima disaster, Japan appears to be building at least three new nuclear power plants on its coastline. The Nuclear Stations Map shows all the nuclear plants in the world, whether decommissioned, in operation, or under construction. Currently, the map highlights over 60 new nuclear reactors being built around the globe.

After the Fukushima disaster, Germany decided to phase out nuclear power, a process completed in 2023. At the time, the environmental and human cost of the Fukushima nuclear accident in 2011 seemed to signal the decline of nuclear power as a viable energy option for most countries. However, the war in Ukraine and the subsequent surge in energy prices appear to have sparked a renewed interest in nuclear energy.

The Straits Times directly addresses this resurgence in its scrollytelling story map On the nuclear trail: The dawn of a global renaissance in nuclear energy. Poignantly, this guided tour of the world’s renewed interest in nuclear power starts with just three locations highlighted on the world map: Three Mile Island, Chernobyl, and Fukushima - the sites of the world’s three worst nuclear disasters.

The recent announcement that Microsoft had signed a deal to purchase nuclear power from Three Mile Island is emblematic of how energy security now seems to outweigh lingering fears of nuclear accidents. The Straits Times story map goes on to show the large number of nuclear power stations currently under construction across many countries. According to the accompanying article, “25 countries – including France, Japan, and the United States – have pledged to triple global nuclear energy capacity by 2050.”

The article is also illustrated with an interesting gridded cartogram that visualizes how much of each country’s electricity generation comes from fossil fuels, renewables, or nuclear energy. As you scroll through the article, individual countries are highlighted on the cartogram to explain the reasons behind their energy mix. For example, “In France, nuclear energy powers up to 70 percent of the country’s electricity needs. However, it has not built a new reactor since 1999 and is now planning to construct 14 more reactors by 2050.”

The reemergence of nuclear power signals a pivotal moment in the global energy landscape. Faced with the dual crises of climate change and energy insecurity, countries are increasingly turning back to a power source many had once sworn off. However, while the promise of clean, reliable energy is alluring, we shouldn't forget that past nuclear disasters have left parts of Chernobyl and Fukushima uninhabitable.
