What the chart shows
Global electricity generation grew by 849.9 TWh from 2024 to 2025. Solar added 646.3 TWh, or 76% of that net increase.
World annual electricity generation, 2024–2025 comparison. Companion source series cover 2000–2025.
How it was made
Select nine mutually exclusive electricity sources from the World annual data. Sum their 2025 year-over-year generation changes, including declines. Divide the solar increase by the net increase. Combined categories are excluded from the sum.
Definitions & limits
- The 76% refers to the net annual increase, not solar’s share of all electricity generation.
- This measures electricity generation, not total energy consumption.
- Ember revises its source over time; this is the fixed 12 October 2026 snapshot.
