World Hits Historic Renewable Energy Milestone as Clean Power Reaches 49.4%

The world has reached a historic turning point in the global energy transition, with renewable power now accounting for 49.4% of global electricity capacity according to new data from the International Renewable Energy Agency (IRENA). This milestone represents the culmination of unprecedented growth in clean energy deployment and signals that renewable technologies have moved from alternative to mainstream. The achievement follows a record-breaking 2025 that saw nearly 700 GW of new renewable capacity installed worldwide.

Solar power led the charge with over 540 GW of new installations, while wind energy added 159 GW. Together, solar and wind now represent 35% of total global electricity capacity—a remarkable transformation that has accelerated dramatically over the past decade. This tipping point carries profound implications for global climate efforts, energy security, and economic development. As renewables approach majority status in global electricity capacity, the fundamental economics of power generation continue shifting toward clean technologies that offer increasingly competitive costs alongside environmental benefits.
