Countries by Renewable Energy Share 2025

About This Dataset

Countries ranked by the percentage of total electricity generation derived from renewable sources in 2025, including hydropower, wind, solar, geothermal, and biomass, according to IEA and IRENA data. Iceland and Costa Rica lead the world in renewable electricity share by a considerable margin — Iceland draws on an extraordinary natural endowment of geothermal energy and glacial rivers that allows it to generate virtually all of its electricity without combustion of any kind, while Costa Rica has sustained near-total renewable electricity generation for over a decade by combining hydropower, geothermal, wind, and solar in a balanced portfolio that has become a benchmark for energy transition policy in developing nations.

Analysis

Iceland heads the table on 99.9, ahead of Costa Rica (99.2) and Norway (98.5) in Renewable Energy Share (%) in 2025. 75.9 separates the highest figure (99.9) from the lowest (24). First and second are separated by 0.70, so the leader sits inside the field rather than apart from it. The field is close behind: 6 of the 8 sit at half the leader's figure or above (50.0+).
