Renewables’ Historic Milestone and Global Emissions Impact Reaffirmed

The landmark achievement of wind and solar power overtaking fossil fuels in the European Union’s electricity generation in 2025, as confirmed by Ember’s latest data, remains a defining moment for global energy systems. This milestone is a testament to robust policy frameworks, technological advances, and sustained capital flows catalyzing the clean energy transition in Europe and beyond.

The International Energy Agency’s (IEA) 2023 report further underscores renewables’ global climate impact by estimating that clean energy sources avoided over 2.7 gigatons of CO₂ emissions in that year alone—equivalent to the annual emissions of the United States or China. This scale of emissions avoidance validates the aggressive deployment strategies so far but also highlights the critical urgency of grid modernization and permitting reforms to ensure system reliability amid growing intermittency.
