Global renewable energy capacity recorded a historic rise in 2025, with nearly 700 gigawatts (GW) added worldwide, highlighting accelerating momentum in the clean energy transition. According to a report by International Renewable Energy Agency, total renewable capacity reached 5,149 GW, marking a 15.5% annual increase.

The report shows renewables accounted for 85.6% of total global capacity additions, significantly outpacing non-renewable sources. The trend reflects a growing shift toward domestic energy systems amid concerns over supply disruptions and fossil fuel price volatility.

Solar and Wind Lead Global Expansion

Solar energy remained the dominant driver of growth in 2025. It contributed about 511 GW, representing nearly 75% of total renewable additions. Wind energy followed with 159 GW, pushing combined solar and wind contributions to 96.8% of net additions.

Other technologies recorded modest growth. Bioenergy added 3.4 GW, while hydropower expanded by 18.4 GW. Geothermal and off-grid solutions also saw incremental increases, supporting diversified energy systems.

IRENA Director-General Francesco La Camera said the steady expansion highlights the resilience of renewable energy systems. He noted that decentralized energy models can improve stability and reduce exposure to global market fluctuations.

Regional Trends Show Uneven Growth

Asia led global expansion, contributing 74.2% of new capacity additions, equivalent to 513.3 GW. The region’s total renewable capacity reached 2,891 GW. Europe followed with 934 GW in total capacity.

Africa recorded its fastest growth rate at 15.9%, adding 11.3 GW. The Middle East also posted strong growth of 28.9%.

However, disparities persist. Central America and the Caribbean reported the lowest capacity at 21 GW, indicating gaps in renewable adoption.

Energy Security and Future Outlook

The report highlights that rising geopolitical tensions are increasing focus on energy security. Countries are expanding renewable capacity to reduce reliance on imported fuels and stabilize energy supply.

The continued dominance of solar and wind, along with expanding regional investments, signals a long-term structural shift in global energy systems.
