Iceland generates 100% of its electricity from renewables — almost all from geothermal and hydro. Coal-heavy countries barely scrape 5%.
How to Play: Guess if the country on the right has a HIGHER or LOWER renewable energy share than the one on the left.

Top 10 Most Renewable-Powered Countries
Renewable share measures the percentage of electricity generated from renewable sources (hydro, wind, solar, geothermal, biomass). It varies enormously by geography and policy.
| # | Name | Renewable Share (% of electricity) | Unit |
|---|---|---|---|
| 1 | Iceland | 100 | % |
| 2 | Paraguay | 100 | % |
| 3 | Norway | 99 | % |
| 4 | Costa Rica | 99 | % |
| 5 | Albania | 95 | % |
| 6 | Bhutan | 95 | % |
| 7 | Ethiopia | 95 | % |
| 8 | DR Congo | 95 | % |
| 9 | Brazil | 87 | % |
| 10 | New Zealand | 80 | % |
How Energy Mix Varies
Iceland’s 100% comes from massive geothermal resources (volcanic island) plus hydro. Norway is 99% hydro. Paraguay’s grid is dominated by the Itaipú dam (largest hydro by output globally).
China is the world’s largest producer of solar and wind in absolute terms — but 32% renewable still leaves the rest from coal and natural gas. China generates more solar/wind than the US, EU, and India combined.
Saudi Arabia at 0.4% is striking — vast oil reserves disincentivize renewable investment. Its Vision 2030 plan aims for 50% renewable by 2030, requiring massive solar buildouts.
Frequently Asked Questions
Highest renewable share?
Iceland (100%) and Paraguay (100%) — both fortunate to have abundant geothermal/hydro resources for small populations.
Why is China at 32% but leading absolute solar?
China’s grid is enormous and majority coal. Even a small percentage growth = huge absolute additions. By 2030 China aims for 50%+.
Are these for electricity only?
Yes — share of electricity generation. Total energy (including transport, heating) is much harder to renewable-ize and lower across the board.
Will fossil-heavy countries catch up?
Slowly. India targets 50% renewable by 2030, US 80% by 2030. Saudi Arabia and Russia have less political pressure.
