Hydropower's share

Hydropower's share of each country's electricity production, as a percentage — nine data points from 1985 to 2024.

Our World in Data (Energy Institute + Ember), hydro_share_elec column — 207 sovereign countries covered.

Time slider. Unlike coal or gas, a given country's hydro share barely moves from one year to the next: it depends on terrain and river networks, not a recent energy-policy choice.

Bhutan (100%) and Paraguay (99%, most of it exported to Brazil and Argentina via the Itaipu dam) owe their electricity almost entirely to hydropower — an accident of mountainous terrain or a major river, not a recent political choice.
