What We’re Showing
This graphic compares the clean energy share of electricity generation in 2015 versus 2024 for 10 of the world’s largest economies, using data from Ember’s Global Electricity Review 2025.
“Clean energy” here includes hydro, wind, solar, and nuclear generation; the “pp” figure is simply the 2024 share minus the 2015 share, not a growth rate.
Key Takeaways
- The UK added the most over the period at +19.5 percentage points (45.4% → 64.9%), followed by Japan at +15.9 pp and Germany at +14.6 pp — all driven largely by wind and solar buildout.
- France remains the outlier on level, with 94.9% of its electricity already clean thanks to its nuclear fleet, leaving it only 2.8 pp of incremental headroom.
- Canada is the only country in the set to backslide, shedding 1.4 pp as its clean share dipped from 79.1% to 77.7%.
