Each country is shaded by its value, in five groups holding the same number of countries. Hover a country for its value, or select it to open its profile. Below the map, each continent’s middle country.
Darker is a higher value. This statistic has no better end, so the shades describe size, not success.

The spread
183 countries, one dot each, on one scale — further right is a higher value. Half the countries are above 0.00%; a quarter are above 0.00%, and a quarter below 0.00%. The bar in each row marks that continent’s middle country.
04All 193 ever measured
Every country
In order, highest value first. No rank or position is shown: too many countries share the same value for an order to mean anything. Neither end is better, and most countries read zero because they have no reactors. Read it beside the low-carbon and renewable columns: nuclear is the reason a country like France is nearly all low-carbon while only a minority of its power is renewable, and Norway, with no reactors, reads the same on both.

Over time
Each point is one year from 2000. Reactors are built and retired over decades, so most lines are flat or step up and down; a sudden dip is often maintenance or an outage rather than a change of policy.

08The measure
About nuclear electricity
This is the share of a country’s electricity generation that came from nuclear power. It is the difference between a country’s low-carbon share and its renewable share, which is why the two can tell such different stories about the same grid.
What the number is: Nuclear (% of electricity generated).

11Questions
Nuclear electricity: questions and answers
Which country has the highest nuclear electricity?
France, at 67.40%, among the 183 countries compared in 2024.
Which country has the lowest nuclear electricity?
152 countries share the lowest reading, 0.00%, among the 183 compared in 2024, so no single country is named.
How many countries does the Nuclear Share of Electricity Generation cover?
183 in 2024, and 193 at least once across all editions. The number measured varies from 183 to 193 between editions.
What is the world average nuclear electricity?
This site does not calculate a world average, which would depend on how countries are weighted. In the middle country of the 183 compared in 2024, the figure was 0.00%.
Is this Ember’s own ranking?
No ranking is shown. Ember publishes values only, and too many countries share the same value for an ordering to mean anything, so none is derived.
How often is the Nuclear Share of Electricity Generation published?
This site holds 25 editions, describing 2000 to 2024.
Where does the data come from, and can I download it?
From Ember, under CC BY 4.0. From Ember’s Yearly Electricity Data, the same public download its own data explorer offers. The percentages are Ember’s own, not recomputed here; where Ember prints no nuclear row for a country, the country is left out rather than shown as zero. Every edition is on this site’s Datasets pages as a full table, and downloads as a CSV file with every value unrounded.

How this page reads the numbers
- No rank or position is shown: Ember publishes values only, and too many countries share the same value for an ordering to mean anything.
- This statistic has no better end, so the page describes higher and lower values and never calls a country a leader.
- A country is named at an end only when it holds that value alone. Where several share it, the page says how many and names none first.
- Values are stored exactly as published and trimmed only for display. “The middle country” is the median of the countries measured, not a world average.
The file itself, column by column — where it came from, what each column holds, and every edition as a CSV — is on its dataset page.
