Analysts are increasingly pointing to nuclear energy as a potential lifeline for Europe in the wake of an energy import crisis triggered by the effective closure of the Strait of Hormuz during the U.S.-Iran war [1]. The crisis has exposed Europe's vulnerability to disrupted energy imports, prompting renewed interest in nuclear power as a means to bolster energy security [1]. France stands out as the leader in nuclear energy within Europe, generating over 60% of its power from nuclear sources, which has resulted in significantly lower energy prices compared to Germany [1].
Despite nuclear energy's advantages—such as lower emissions, minimal land use, and high reliability—analysts caution that high upfront costs, waste disposal challenges, and historical accidents have made European nations hesitant to expand their nuclear programs in recent decades [1]. However, the current supply shock is seen as a turning point, with IEA chief Fatih Birol stating that nuclear power would receive a 'boost' from the crisis and urging governments to diversify their energy sources [1].
Chris Seiple, vice chairman of Wood Mackenzie's power and renewables division, emphasized that nuclear must play a significant role in solving Europe's energy supply issues, while Michael Browne of Franklin Templeton noted that countries lacking natural energy supplies face higher costs unless they invest in nuclear infrastructure [1]. As of 2025, nuclear energy accounts for just 11.8% of Europe's total energy mix, with oil and gas still making up over a third, according to Eurostat data [1].
The crisis is also influencing energy strategies beyond Europe. South Korea's climate minister, Kim Sung-hwan, described the Iran war as a 'significant turning point' for his country to shift away from oil and toward nuclear and renewables, which he identified as the 'two central pillars' of future energy supply [1]. This raises questions about whether other European countries, such as the U.K. and Germany, will reconsider their nuclear policies to better insulate themselves from future supply shocks [1].
CONCLUSION
The current energy import crisis has reignited debate over nuclear energy's role in Europe, with analysts and officials highlighting its potential to enhance energy security despite cost and waste challenges. France's success with nuclear power provides a model, and the crisis may prompt other nations to reconsider their stance on nuclear energy. The market takeaway is a cautiously positive outlook for nuclear energy's prominence in Europe's future energy mix.
