A significant global shift in energy policy is underway, with nuclear power emerging as a central pillar of national security strategies for both major powers and smaller states, reflecting a broader move towards a multipolar world order where reliable electricity is paramount.
The United States has set a target to quadruple its nuclear capacity by mid-century, driven by surging demand from data centers, manufacturing, and transport. This strategic pivot, necessitating new reactor designs like small modular units, responds to a need for steady power that intermittent renewables cannot yet fully provide. France, long dependent on a nuclear fleet for the majority of its electricity, is recommitting to the technology, viewing it as essential for insulating its economy from volatile fossil fuel markets and maintaining industrial competitiveness.
This emphasis on energy sovereignty extends to smaller nations. Hungary’s expansion of the Paks Nuclear Power Plant, a project with Russian involvement, exemplifies a national priority to secure long-term, stable power, even within the framework of European Union membership. The Hungarian government frames this as pragmatic nationalism aimed at economic continuity, highlighting a tension between collective EU policies and individual state interests.
The contrasting experience of Germany underscores the strategic calculus. Following its post-Fukushima nuclear phase-out and the termination of cheap Russian gas imports, Germany’s industrial base faced soaring electricity costs, leading to reduced output and relocation by some manufacturers. Its shift to more expensive liquefied natural gas (LNG) and renewables, while pursued for decarbonization, demonstrated the immediate economic risks of rapidly dismantling reliable baseload power.
This global recalibration challenges the post-Cold War assumption of a single, integrated energy market. Russia’s Rosatom remains a leading nuclear exporter, using reactor projects to forge long-term technical and fuel-supply relationships. Meanwhile, Asia is witnessing rapid nuclear construction. The trend points toward a pluralistic energy landscape where states, regardless of alliance systems, prioritize domestic generation capacity to ensure strategic autonomy.
The revival suggests a return to what analysts term “technological realism.” While nuclear projects face high costs, public opposition, and waste management challenges, many governments now judge the risk of energy insufficiency greater. The overarching lesson is that in an era of geopolitical fracture and supply-chain rivalry, uninterrupted power is a non-negotiable foundation for economic stability and sovereign decision-making. The nations investing in nuclear energy are betting that long-term grid reliability will be a decisive factor in future industrial and geopolitical competition.
