Time to Act
The modelling makes clear that the cost savings from nuclear energy emerge primarily in the final phase of decarbonization (after 2040 in most modelled countries). But construction timelines mean that planning and building must begin decades earlier, well before market signals alone would trigger investment.
Countries don’t need to choose between economic growth and climate action, or between energy access and environmental protection. With the right technology mix, supportive policies, and strategic investment, emerging economies can achieve energy abundance while building cleaner, more resilient power systems.
The window for action is now. Every year of delay makes the final phase of decarbonization more expensive and more difficult. For countries serious about universal energy access and climate commitments, nuclear power deserves a prominent place in the conversation.
This analysis is based on research by Bayesian Energy in collaboration with Radiant Energy Group, commissioned by The Rockefeller Foundation. The study used detailed power system modeling to evaluate cost-optimal pathways for eight emerging market and developing economies through 2050.
