G7

In 2025, the G7 generated more electricity from clean sources than fossil fuels for the first time – 50.3% from clean sources and 49.7% from fossil fuels.

Together, the G7 countries – Canada, France, Germany, Italy, Japan, the United Kingdom and the United States – were responsible for 18% of global power sector emissions in 2025, down from around a quarter (26%) in 2015.

Coal generation has almost halved  since 2015, reflecting old coal power plant closures and declining utilisation of remaining plants. At the same time, wind and solar have expanded rapidly. Since 2015, wind and solar generation in the G7 has almost tripled.

The G7’s share of global fossil-fuel based electricity generation and the associated emissions has continued to decline, reflecting a structural shift in its power systems. This has been driven primarily by the rapid expansion of solar and other renewables, which are increasingly displacing fossil fuel generation across the bloc. 

However, fossil fuels still play a significant role in some of the group’s largest power systems. In 2025, the United States generated more than half  of its electricity from fossil fuels, while Japan relied on fossil fuels for two-thirds  of its generation. 

As a result, the G7 accounted for over a third (37%) of global electricity generation from fossil gas in 2025, with the United States responsible for around 70% of the group’s gas-fired output and 26% of global gas generation.

Overall, despite rapid renewable energy growth, fossil fuels remain significantly embedded in parts of the G7 power mix.
