The spread
190 countries, one dot each, on one scale — further right is a higher value. Half the countries are above 11.022%; a quarter are above 43.222%, and a quarter below 0.050%. The bar in each row marks that continent’s middle country.
04All 200 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. A high share mostly reflects rivers and mountains, and a low share is not a failure; the renewable column beside it shows how much of the rest comes from wind, solar, bioenergy and geothermal.

Over time
Each point is one year from 2000. A new dam lifts the line in a step, and a dry year can pull it down sharply, so a single low year is often the weather rather than a change of course.

About hydropower
This is the share of a country’s electricity generation that came from hydropower. It is the reason countries such as Norway, Paraguay, Nepal and Ethiopia run on clean power without a wind or solar boom.
What the number is: Hydropower (% of electricity generated).

11Questions
Hydropower: questions and answers
Which country has the highest hydropower?
Bhutan, at 100.000%, among the 190 countries compared in 2024.
Which country has the lowest hydropower?
44 countries share the lowest reading, 0.000%, among the 190 compared in 2024, so no single country is named.
How many countries does the Hydro Share of Electricity Generation cover?
190 in 2024, and 200 at least once across all editions. The number measured varies from 190 to 200 between editions.
What is the world average hydropower?
This site does not calculate a world average, which would depend on how countries are weighted. In the middle country of the 190 compared in 2024, the figure was 11.022%.
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 Hydro 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; pumped-storage hydro is left out where Ember can separate it. 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.
