According to industry data, global solar power generation has surpassed nuclear power generation in annual electricity statistics for the first time, marking a further rise in the position of renewable energy in the energy mix. The milestone reflects a decade of rapid declines in photovoltaic installed capacity and generation costs, alongside the aging-and-new-build dilemmas facing nuclear power in many countries.

• Milestone data: Industry research shows that global annual solar generation has surpassed annual nuclear generation for the first time, with PV continuing to gain share in electricity supply across multiple countries.
• Cost drivers: PV module costs have fallen by more than 80 percent over the past decade, combined with declining storage costs and progress in power-market reform, sharply boosting solar competitiveness across regional electricity markets.
• Nuclear dilemma: Some countries face high life-extension costs and tighter safety reviews for aging nuclear units, while new-build projects progress slowly due to long investment cycles and varying public acceptance.
• Regional divergence: Europe, North America, and the Middle East show clear divergence in nuclear policy; some countries extend the life of operating plants, while others accelerate phase-out and fill the gap with renewables.
• Next-stage challenges: Grid absorption capacity, energy-storage support, and cross-regional transmission have become the key variables determining whether solar can expand further, and multiple countries are accelerating related infrastructure investment.

[Panorama]

The solar-surpasses-nuclear milestone is not a simple number swap but a signal of structural change in the energy system. While the cost curve on the generation side continues to decline, grid-side absorption capacity, storage support, and cross-regional transmission have become the real bottlenecks for further solar expansion. National energy policies need to keep pace with grid upgrades alongside capacity expansion, otherwise rising curtailment rates and electricity-price volatility may in turn dampen investment appetite. Over the long term, the role of solar and nuclear will shift from “zero-sum competition” toward “complementary coexistence,” and flexible resources, storage investment, and market-mechanism design will become the core agenda for the next phase of the energy transition.
