Recent events on the Iberian Peninsula have sparked a renewed debate over the future of nuclear energy in Europe, particularly after one of the largest power outages in decades left millions without electricity. This incident has spurred a reassessment of renewable energy's reliability and reignited discussions about the role of nuclear power in meeting the continent's escalating energy demands.

The blackout that affected Spain and Portugal has drawn attention to the vulnerabilities of a grid heavily reliant on renewable energy, which accounted for approximately 70% of Spain's electricity at the time. Experts suggest that this dependency may have hindered efforts to maintain grid stability. Despite these concerns, Spanish Prime Minister Pedro Sánchez staunchly denied that the blackout was linked to an excess of renewable energy, asserting in parliament that attributing the incident to a lack of nuclear capacity was misguided.

However, voices in the energy sector advocate for a different perspective. Ignacio Sánchez Galán, the CEO of Iberdrola, warned that cutting nuclear power could lead to a spike in electricity prices by up to 25% and a significant reduction in system reliability. In a similar vein, Sama Bilbao y León, representing the World Nuclear Association, expressed alarm over Spain's impending decisions to phase out its nuclear reactors, emphasising that the country’s economic future hinges on a stable supply of clean energy.

As Spain grapples with its energy strategy, countries like Germany are reassessing their previous anti-nuclear policies. The recent election of Chancellor Friedrich Merz has prompted discussions around potentially reviving the country’s nuclear energy programme, which was markedly curtailed following the widely publicised Fukushima nuclear disaster. Merz’s administration is exploring investment in new technologies, including small modular reactors (SMRs), which are seen as more cost-effective and versatile than traditional nuclear plants.

Indeed, a global trend appears to be emerging, with a notable shift in attitudes towards nuclear energy. Australia’s government has lifted its ban on nuclear power, signalling intent to invest heavily in new reactors, while Taiwan is poised to vote on the potential restart of a nuclear reactor to meet surging energy demands from its primary economic sector—semiconductors. The rising energy needs tied to artificial intelligence and extensive data operations underscore the urgency for reliable power sources, further adding to nuclear power’s appeal.

In the United States, the discussion has further evolved, particularly with the significant energy requirements anticipated from tech giants like Microsoft and Amazon. Contracts for new nuclear capacity are emerging, reflecting a growing acceptance of nuclear energy as a viable option to meet the demands of AI data centres. This trend is ingrained in a broader drive to reduce carbon emissions while ensuring round-the-clock power availability.

Despite these shifts, challenges remain surrounding the reliability of aging nuclear infrastructure. Facilities like Torness in Scotland are facing hurdles as critical components deteriorate, prompting calls for cautious updates rather than outright closures. Experts argue that the expansion of existing nuclear facilities, exemplified by the push for even older plants to extend their operational life, should be approached with caution given historical records of budgets running over and schedules slipping.

As European nations navigate the complexities of energy policy, Spain’s government is under pressure to reconsider its planned nuclear phase-out. Industry leaders, including José Bogas of Endesa, are advocating for a review of the closure timeline, arguing that changing energy demands necessitate a reevaluation of nuclear energy's role. The consensus is clear: a balanced and adaptable energy strategy is key to achieving sustainability without compromising economic stability in the face of growing power consumption demands.

The conversation around nuclear energy is far from settled. With advocates highlighting the urgency of reliable energy supplies in an evolving market, and detractors citing historical issues associated with nuclear technology, the coming years will be crucial in determining whether nuclear energy can reclaim its place as a cornerstone of Europe’s energy strategy.
