The numbers tell one story.
Renewable energy is getting a fresh push from the war in Iran. The crisis has exposed the risks of relying on oil and gas supplies, leading to a surge in interest in renewable energy. IRENA reports that renewable power accounted for 85.6% of all new energy capacity installed worldwide in 2025. Countries are now reconsidering their energy strategies, with a focus on decentralized energy systems and homegrown domestic energy sources. The conflict has accelerated the transition to renewables, with Fatih Birol, executive director of the International Energy Agency, expecting an acceleration of renewables as countries consider their alternatives.
The war is being used as a catalyst for the energy transition.
