Solar Overtakes Nuclear Power Globally

Globally, solar electricity generation has officially surpassed nuclear power, a significant energy source since the late 1970s. By late 2026, solar is producing 13% more electricity than all nuclear plants worldwide, a milestone previously unforeseen by major energy projections. This growth marks solar as the fastest and largest source of new electricity generation in history, meeting three-quarters of the world's increased electricity demand in 2025.

The dramatic rise is attributed to several factors, including a sharp decrease in solar panel costs, driven significantly by China's vast manufacturing capacity and oversupply, pushing module prices to record lows. Solar electricity became the cheapest in history in 2020 and continues to fall, making it an "offensively cheap" energy source.

Countries like China, the US, and India are leading solar installations, with significant growth also seen in Australia, Pakistan, Lebanon, and across Africa. Escalating fossil fuel prices, influenced by geopolitical events, have further boosted solar's economic advantage, especially in regions with unreliable grids.

Paired with advancements in battery technology, solar power is increasingly capable of providing dispatchable electricity. Solar and battery systems are now often cheaper than new fossil fuel plants in sunny regions, addressing the challenge of storing solar energy for evening use. While seasonal storage remains a hurdle, solar's integration into broader electricity systems is progressing.

Future outlooks predict continued strong growth, with solar expected to double 2025 generation levels by 2030 and overtake hydropower as the world's third-largest electricity source. However, the rate of expansion may slow due to policy changes in China, though other countries continue to install more panels. The primary constraints on solar's continued growth are now grid infrastructure and the pace of electrification, rather than panel availability or cost.
