Nuclear power’s share grows as more reactors are built in emerging markets
About 80 nuclear reactors are currently under construction, and most are being developed in emerging economies rather than traditional nuclear-heavy countries.
OilPrice says the global shift toward nuclear power is accelerating as countries face an “energy trilemma,” balancing affordability, sustainability, and security, while AI-driven demand growth and recent oil shocks intensify pressure on electricity supply.
The outlet notes nuclear development is historically concentrated in wealthier nations because projects are costly and require strong governance to manage nuclear waste, with the United States, France, China, Russia, and South Korea together accounting for more than 70.0% of global nuclear energy output.
OilPrice also highlights that this pattern is changing, with 80 nuclear reactors currently under construction worldwide, the majority located in emerging economies and representing a move beyond the established nuclear leaders.
