Overview

• Ember’s H1 2025 analysis shows renewables generated 5,072 TWh versus coal’s 4,896 TWh, the first recorded global lead for clean power.
• Global solar output jumped about 31% year over year, adding roughly 306 TWh and supplying around 83% of the increase in electricity demand.
• Fossil generation edged down overall, with coal falling by about 31 TWh and gas by about 6 TWh, contributing to an estimated 0.2% drop in power‑sector CO2 emissions.
• The trend was uneven: fossil generation declined in China and India as clean power expanded, but rose in the US and EU due to faster demand growth and weaker wind and hydro.
• Ember’s findings draw on monthly data from 88 countries covering about 93% of demand, as the IEA projects capacity to keep rising this decade with solar leading growth.
