Solar vs. nuclear electricity generation

By Dror Poleg

This chart compares global electricity generated from solar and nuclear power. It uses annual Ember generation data in terawatt-hours, showing actual output rather than installed capacity; similar totals do not imply similar reliability, economics, or grid value.

Latest observation: 2025·Expected cadence: Annual

What does it show?

Annual solar generation has nearly caught up with nuclear power globally.

Methodology

Annual global electricity generation from Ember's Solar and Nuclear categories, shown in terawatt-hours without indexing or smoothing. The chart compares the convergence of the two annual series; it does not claim solar has overtaken nuclear before the published annual observations cross.
