Natural gas is losing its grip on the global power mix as countries increasingly turn to cheaper, more secure renewable energy, according to a new report from climate and energy think tank Ember.
Ember’s analysis found that 61 out of 124 economies that generate electricity from gas have already passed peak gas power generation. That includes four G7 countries: the UK, Germany, Italy, and Japan.
Solar is crushing gas growth
The share of gas in the global electricity mix fell for the fifth straight year, dropping from 23.9% in 2020 to 21.8% in 2025. Gas generation still increased slightly overall, but growth has slowed dramatically as solar and wind meet more of the world’s rising electricity demand.
In 2025, solar generation grew by 636 terawatt-hours (TWh) – 17 times more than gas generation, which increased by just 38 TWh. Solar alone supplied roughly 75% of new global electricity demand growth last year, while gas contributed only around 5%.
