An International Energy Agency (IEA) report has shown that renewable energy sources are no longer just an environmental option, but have become the primary tool for ensuring energy security, with their growth accelerating to include developing countries outside of China for the first time.
Record Growth Expected Until 2031
In its annual report "Renewables 2026," the Agency projected that global renewable electricity capacity will increase by approximately 4,800 GW during the 2026-2031 period, an increase of nearly 60% compared to the increase recorded in the previous six years. These sources are expected to cover nearly half of global electricity production by 2031.
Solar Power Leads Expansion
Solar power will account for more than three-quarters of the increase in renewable capacity by 2031, followed by onshore wind power. The Agency's Executive Director, Fatih Birol, emphasized that the story of renewable growth has entered a true global chapter, as its spread has extended to all corners of the world, becoming the backbone of the global electricity sector.
China Maintains Leadership and India Emerges
China will remain the largest contributor to renewable capacity growth, though its share may decrease from more than 60% in 2025 to an average of 53% during the forecast period due to policy changes. In contrast, India emerges as the second largest growth market, with its renewable capacity expected to more than double by 2031. Growth is also accelerating in Southeast Asia, the Middle East and North Africa, and Sub-Saharan Africa, where additions may triple compared to the previous period.
Transport Sector Moving Toward Clean Energy
The use of renewable energy in transport is expected to increase by more than 60% by 2031, meeting 6% of the sector's global needs. Renewable electricity used in electric vehicles will contribute about 45% of this increase, while biofuels rank second.
Revision of Biofuel Forecasts
The Agency raised its biofuel forecasts by 40% compared to last year's report, in response to rising fuel prices and supply difficulties, as countries in Southeast Asia and Latin America increased mandatory blending rates of gasoline and diesel with biofuels.
