Clean electricity growth by technology
This chart compares the annual increase or decrease in global electricity generated from solar, wind, hydro, and nuclear power. It uses Ember’s harmonized generation data; the measure captures changes in output, which can reflect weather and utilization as well as newly built capacity.
What does it show?
Solar now contributes far more annual clean-electricity growth than wind, hydro, or nuclear.
Methodology
For Solar, Wind, Hydro, and Nuclear, subtracts each prior-year global generation level from the current calendar year and displays the change from 2010 onward. This compares additions to annual electricity output, not new installed capacity. Negative observations mean that technology generated less electricity than in the preceding year.
