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.

✨ AI Insight

The data reveals a stark contrast between the leaders and the lower-ranking countries in renewable energy adoption. Iceland and Costa Rica are outliers with nearly complete reliance on renewables, primarily due to their unique geographical advantages and long-term policy commitments. Norway follows closely with 98.5%, largely driven by its extensive hydropower resources. In contrast, the United States, with only 24% renewable energy share, highlights the challenges faced by larger economies in transitioning to sustainable energy. The gap between the top performers and the U.S. suggests a need for more aggressive policies and investments in renewable technologies to catch up with global leaders.
