Energy debates often look settled from a distance. Renewables are expanding, costs are falling and the direction of travel seems clear. Yet electricity systems are not assembled from moral categories. They are built from technologies with different production profiles, construction risks, physical constraints and political vulnerabilities. Solar, wind, storage, grids and nuclear are often discussed as though they were competing answers to one question. They are not. A solar panel produces when sunlight is available. A wind turbine follows another weather pattern. A battery moves electricity through time but does not create it. A transmission line moves power between places. A nuclear plant can provide large quantities of low-emissions electricity largely independent of daily weather, but brings financing, construction and operational risks of its own. The difficult question is no longer simply whether electricity should be decarbonised . It is how to assemble a system that continue...

In March 2026, European Commission President Ursula von der Leyen called Europe’s reduction of nuclear energy a “strategic mistake” . It was the sort of statement almost guaranteed to provoke an immediate answer. To some, it sounded like overdue realism. To others, it looked like a convenient attempt to rewrite decades of political choices. But the question is more difficult than either response suggests. Europe did not pursue one nuclear policy, and “retreating from nuclear power” can describe several very different decisions: closing an ageing reactor, refusing a lifetime extension, abandoning a new project, or rejecting the technology entirely. The strongest answer is therefore narrower. Closing safe existing reactors before firm low-carbon replacements, stronger grids and sufficient flexibility were ready was often a strategic mistake. That does not mean every reactor should have remained open, or that every proposed nuclear plant represents good value. It means energy systems ...
