Electricity from nuclear power — share of total electricity generation (2023)

This statistic measures how much of a country’s total electricity generation came from nuclear power in 2023. It highlights where nuclear energy is a central pillar of the power system (often delivering low-carbon, dispatchable generation) versus where it is absent or marginal.

Values are expressed as a percentage of total electricity generation. Countries with operating nuclear plants typically show stable, relatively high shares, while many countries register 0% because they have no nuclear generation. The figures come from Ember’s country-level electricity generation dataset, which compiles national power data and harmonizes it into a consistent global time series.
