Nuclear vs Renewables: The Global Race for Clean, Firm Power

Rising electricity demand is increasing the need for clean, round-the-clock power. Close to 80 GW of nuclear capacity is under construction globally, while renewables and storage are scaling faster than any other source. One side argues for nuclear on firm output, long asset life and the promise of small modular reactors, though cost and delivery timelines remain unsettled. The other argues that renewables with storage are cheaper and faster to build, though dependent on concentrated supply chains. The debate will focus on total system cost, delivery timelines, reliability and land use, and exposure to concentrated supply chains.
