Renewable energy didn’t just make gains in 2024—it completely dominated. An overwhelming 92.5% of all new power capacity added to the grid came from renewable sources, signaling that the transition away from fossil fuels is no longer just a goal but an undeniable reality. Yet, despite this record-breaking growth, the world remains behind schedule in its push for full decarbonization.
In total, 585 gigawatts of new renewable capacity were added, bringing the global total to 4,448 gigawatts. This represents a 15.1% increase over the previous year, the fastest expansion ever recorded according to the International Renewable Energy Agency (IRENA). As expected, solar and wind power were responsible for the vast majority of this growth, accounting for 96.6% of all new renewable installations. Solar power alone surged by 452 gigawatts, an increase of 32.2% compared to the previous year, bringing its total global capacity to 1,865 gigawatts. Wind power followed with 113 gigawatts in new installations, reflecting an 11.1% increase year over year.
Despite these impressive numbers, the challenge ahead remains significant. To meet global climate goals, renewable power capacity needs to reach 11,200 gigawatts by 2030. That would require an annual growth rate of 16.6%, meaning the world must accelerate its transition even further.
China continued to be the driving force behind renewable energy expansion, accounting for nearly 64% of all new capacity additions worldwide. In comparison, all G7 countries combined contributed just 14.3% of the total, while G20 nations made up 90.3%, with China alone responsible for the majority of that growth.
The impact of this surge in renewable energy is undeniable. According to IRENA Director-General Francesco La Camera, the continuous expansion of renewables proves they are not just viable but also economically competitive. However, he also emphasized the persistent challenges of regional disparities and the urgency of meeting the 2030 deadline. United Nations Secretary-General António Guterres echoed this sentiment, stressing that while renewables are reshaping economies, the transition must be both faster and fairer to ensure that all nations can benefit from clean, affordable energy.
The numbers make it clear: fossil fuel expansion is at its lowest level in decades, while renewable energy is breaking records year after year. But while the world is making progress, the pace needs to pick up. The renewable revolution is here, but time is running out to ensure it delivers the transformation needed to combat climate change.
