Coal gives way to wind
- Coal, share of generation
- Wind, share of generation
2026: Coal 0% · Wind 30.6% of generation
In 2009, coal supplied 28% of the mix and carbon intensity averaged 444 gCO₂/kWh.
By 2026, coal’s share is 0% and carbon intensity has fallen to 142 g.
Wind has moved from 1% to 31% of generation over the same years.
