New research by the UK’s Nuclear Industry Association (NIA) and the World Nuclear Association (WNA) shows that an overwhelming majority (87%) of the world’s economy is backing new nuclear power, compared to 5.5% phasing out nuclear, as more countries look to accelerate the rollout of clean, homegrown, baseload power.
The research shows there is a marked shift in governments backing nuclear with several countries indicating a renewed support for nuclear in recent years as they look to strengthen their energy security and energy resilience, including Italy, Denmark, Vietnam and Thailand. At COP29, the UN’s climate conference, 31 countries signed a pledge to triple nuclear capacity by 2050 including France, Canda, Japan, Poland, the United States and the UK.
Other countries are considering their nuclear future, including Germany, which has been phasing out nuclear since 2011, and Taiwan, which is holding a referendum this year on whether to restart its reactors.
The research was conducted by analysing publicly available data from the IMF on the economy size of nations and the nuclear policy of those countries.
