In 2025, something that seemed distant became a reality: solar and wind energy combined reached 4,174 gigawatts of installed capacity worldwide — surpassing coal in global electricity generation for the first time in a century. The 4000 GW solar and wind milestone is not just a symbolic number. It is confirmation that the energy transition has ceased to be a promise and has become the dominant movement in global electrical infrastructure. And Brazil is at the center of this revolution — with the second largest portfolio of renewable projects on the planet, behind only China.
The data was compiled by the energy analysis organization Ember and confirmed by the International Renewable Energy Agency (IRENA) in April 2026. In 2025, the world added 814 gigawatts of new solar and wind capacity — a historic record representing six times more than all other combined energy sources installed in the same period. To put it in perspective: 814 GW is more than Brazil’s entire installed electrical capacity.
The historic shift was not just in capacity. In actual electricity generation, renewables accounted for 33.8% of global production in 2025 — surpassing coal (33.0%) for the first time in approximately 100 years. An era that began with the Industrial Revolution has come to an end.

What’s Behind the 4,000 GW Solar and Wind Explosion
The speed of growth would have been impossible to predict two decades ago. In 2015, the world had about 840 GW of combined solar and wind capacity. In 2025, that number reached 4,174 GW — an almost 5-fold increase in ten years. The compound annual growth rate for solar energy during this period was about 15%
