Scotland at the Crossroads: Why Renewables Are Outpacing Nuclear in the Race Against Time
New analysis from Bennett Scholar Dr Paul Dorfman, alongside leading UK energy experts, highlights a simple but critical truth: time, not cost, is now the defining variable in the energy transition.
As the climate crisis accelerates, the urgency for rapid, effective, and affordable clean‑energy solutions has never been greater.
While Scotland continues to debate the role of new nuclear power, the evidence shows that nuclear simply cannot be built fast enough to address the climate and energy challenges unfolding today. Global construction times for new reactors now exceed 17 years, with consistent delays and cost overruns. Small Modular Reactors, once billed as the next frontier, remain unproven, with no commercial designs yet operating.
Renewables, meanwhile, are accelerating at unprecedented speed. In 2025, more power was generated globally from renewables than from coal, and 91% of new renewable projects were cheaper than fossil fuels. Solar and wind now generate 70% more electricity worldwide than nuclear, and the International Energy Agency forecasts that by 2030, renewables will meet 90% of the world’s electricity demand growth.
The story is similar in Europe. Wind and solar surpassed fossil fuels in power generation in 2025, demonstrating how quickly and reliably a renewables‑led system can scale. In the UK, the Royal Society has already concluded that renewables coupled with long‑duration storage will be cheaper and more feasible than any system that includes new nuclear.
For Scotland, a nation with world‑class renewable resources, this represents both a challenge and an opportunity. The choice is clear: invest heavily in technologies that are already delivering rapid, low‑cost, low‑carbon power, or pursue nuclear options that may arrive decades too late.
As Dr Dorfman and colleagues argue, the future backbone of global power systems will be renewable, flexible, interconnected, and cost‑effective. With its abundant natural advantages, Scotland is poised not just to participate in that future, but to lead it.
