Global Renewable Energy Reaches Nearly 50% of Electricity Capacity

Historic milestone marks tipping point in worldwide energy transition

The world has reached a historic tipping point in clean energy: renewable power now accounts for nearly 50% of global electricity capacity, marking a fundamental shift in how humanity powers itself. According to International Renewable Energy Agency data, renewables made up 85.6% of all new capacity additions in 2025, with total renewable capacity reaching 5,149 GW.
This milestone represents more than statistical achievement—it signals that renewable energy has become the default choice for new power generation worldwide. Solar installations led the surge, driven by plummeting costs and improved efficiency that make clean energy economically superior to fossil fuels in most markets.
The transformation has accelerated beyond most expert predictions. What seemed like an aspirational goal just a decade ago has become economic reality, with renewables now offering the cheapest electricity in most regions while providing energy security and climate benefits.
