Headline finding

Iceland leads the world for highest share of renewable electricity at 100% % of generation from renewables.

What the numbers show

Iceland's lead at the top of this ranking is 0.0% above the second-place country — a margin tight enough that the top spot has changed hands within the last five years and could change again.

The five countries leading the table — Iceland, Paraguay, Albania, Costa Rica, Ethiopia — together set the global benchmark. The next 20 countries fill the rest of the table, with Ecuador anchoring the list at 79%.

Figures are drawn from IRENA Renewable Energy Statistics 2024. We use this source because it produces a single, internally consistent dataset rather than aggregating from national statistics offices, which makes year-on-year comparison reliable. The next update is expected when the source publishes its next annual release — see the methodology section below for which year of data is currently shown.

Coverage
Top 25 countries shown. Full source dataset covers all 195 sovereign states where data is available.
Refresh cadence
Updated annually as the source publishes new figures, typically autumn or spring.
Known caveat
Country definitions follow the source: where the UN, the World Bank and the CIA Factbook disagree on borders or recognition, we use the figure as published rather than reconciling between bodies. Comparisons across rankings should be made with this in mind.
