Low-carbon electricity sources outpaced demand growth in 2025, driving fossil fuel decline
In 2025, low-carbon electricity sources (primarily solar and wind) grew faster than global electricity demand for the first time, pushing fossil fuels into absolute decline. According to Ember's Global Electricity Review, global electricity generation increased by ~850 TWh from 2024 to 2025, with solar and wind accounting for nearly all of that growth. This marks a significant turning point in the energy transition, as renewables are now not just gaining share but actively displacing fossil fuel generation.
