The world’s cumulative renewable energy capacity exceeded 3,000 gigawatts (GW) for the first time in early 2026, according to the International Renewable Energy Agency (IRENA). This landmark achievement reflects accelerated investments and technological advancements in solar, wind, hydro, and other clean energy sources. Experts attribute the surge to supportive government policies, declining costs, and heightened corporate commitments to sustainable energy transitions.
Solar power accounted for nearly 45% of the total renewable capacity, with wind energy contributing 35%. The remainder included hydropower, bioenergy, and emerging technologies such as green hydrogen. Despite this growth, global energy demand continues to rise, emphasizing the need for further expansion and integration of renewables to meet climate targets.
IRENA’s Director-General, Francesco La Camera, emphasized the importance of continued international cooperation and finance mobilization to sustain momentum. “Achieving the 3,000 GW milestone is encouraging, but the journey towards net-zero emissions by 2050 requires scaling up efforts and addressing systemic barriers,” he said. Policymakers and industry leaders are urged to accelerate deployment and grid modernization to ensure reliable and equitable access to clean energy.
