Gas share in global electricity mix declines for fifth straight year as renewables surge
By
Malgorzata Wiatros-Motyka Senior Electricity Analyst Ember
Summary
Global gas share in electricity generation has declined for the fifth consecutive year in 2025, as clean power growth outpaced rising electricity demand. While global electricity demand has more than doubled since 2000 (from 15,279 TWh to 31,774 TWh), renewables are increasingly meeting new demand rather than fossil fuels. This trend suggests the world may be approaching a peak in gas-fired power generation.
