China's fossil generation fell 0.7% in the last twelve months (Q4 2024-Q3 2025). compared to the previous twelve-month period.

India’s fossil generation declined by 2.5% in the twelve months to Q3 2025.

Why?

Mainly surging solar, wind & batteries.

IEA said in 2010 that 410 GW of solar would globally operate in 2035.

In 2025, there is already four times that amount of solar globally.

Small solar (<1 MW) was 42% of global solar deployment in 2024, up from 22% in 2015.
