The global solar boom has wildly exceeded expectations, with capacity already four times higher than 2010 forecasts for 2035, helping lower predicted warming from 4°C to 2.6°C.
However, momentum is now stalling. The US has scrapped subsidies and tightened permitting, making the global goal to triple solar capacity by 2030 likely out of reach. Despite clean energy gains, overall emissions continue to rise due to growing energy demand.
