Nuclear Energy Returns to the Global Stage as Demand for Clean Electricity Surges

The world is witnessing a new turning point toward nuclear energy, with countries such as the United States, France, Japan, and the United Kingdom announcing plans to build new reactors or restart decommissioned plants, marking a striking shift away from the post-2011 Fukushima disaster phaseout trajectory.

This shift is driven by two main factors: first, the growing need for carbon-free clean energy, and second, the immense electricity demand from data centers dedicated to artificial intelligence, which now consume record amounts that intermittent renewable energy sources alone cannot fulfill.

In this context, Small Modular Reactors (SMRs) are emerging as the ideal solution for the future, with companies like NuScale and Terra Power intending to build prototypes by the end of this decade, while tech giants such as Microsoft and Google have secured long-term contracts for clean nuclear power.

Energy experts believe that nuclear power will be an indispensable element in the global energy mix by 2035, warning that countries that delay building nuclear capacity will pay a heavy price in the race to compete for reliable, low-carbon clean energy.

What do these terms mean?

Small Modular Reactors (SMRs): Nuclear reactors that are smaller in size and easier to build than traditional reactors. They can be assembled in a factory and transported to the operational site, reducing construction costs and building time.

Clean Nuclear Energy: Electricity produced from nuclear reactions without significant carbon emissions during operation, making it a competitor to solar and wind energy in the climate context.

Data Centers: Massive facilities housing thousands of servers that power artificial intelligence applications and cloud computing, consuming huge amounts of electricity around the clock.
