Solar Power Now Generates 13% More Electricity Than Nuclear Globally

Solar electricity generation overtook nuclear power globally in 2025 and now produces 13% more power. Solar has grown from 1% of global power a decade ago to an expected 10% in 2026, becoming the fastest-growing source of new electricity in history and the largest source of new electricity globally in 2025.

Nuclear power generation has remained relatively constant since 2000, while solar's dramatic growth reflects both technological advances and falling costs rather than an absolute decline in nuclear.
