According to Ember's research, the Paris Agreement has accelerated solar power as the quickest-expanding electricity source globally. Generation has risen tenfold from 1% in 2015 to 6.9% in 2024 and 8.8% in the first half of 2025. Emerging economies now contribute over half of solar output, up from under a quarter, as mature markets' portion fell from three-quarters. In Brazil, solar capacity has expanded 70% yearly to 62 GW by September 2025, providing 12% of electricity in the first three quarters. This has outpaced nuclear, coal, gas, and bioenergy, also reducing reliance on 90% hydro via auctions and distributed generation.
