Global Renewable Energy Capacity Surpasses 5.2 Terawatt Milestone

Total installed renewable capacity reached 5,155 GW at the end of 2025, up 15.1% in one year, while renewables represented 49.5% of global installed power capacity. For the environmental-restoration audience, the milestone is significant because it quantifies deployment at continental scale, even though more capacity does not automatically resolve generation, storage, or grid-integration constraints.

Growth has accelerated beyond its recent norm

The 15.1% annual increase was well above the 11.9% average recorded between 2019 and 2024. Renewables also accounted for 85.7% of all new power-generation capacity added during 2025.

There was one important qualification: that share was down from 92.7% in 2024. MVA Pulse attributed much of the decline to a rebound in coal-fired additions, particularly 83 GW added in China.

That combination creates a clear empirical picture. Renewable capacity is expanding quickly, but the rest of the power system is not standing still. The capacity milestone therefore measures progress in infrastructure deployment; it does not, by itself, settle how much electricity renewables generate, how much fossil generation is displaced, or whether grids can balance variable supply consistently.

Solar and wind carry most of the expansion

Solar remained the largest renewable technology, with 2,397 GW of installed capacity, or 46.5% of the global renewable total. Wind followed at 1,291 GW, representing 25%.

Together, the two technologies supplied 96.9% of all net renewable capacity additions in 2025. Global solar capacity alone increased by 514 GW during the year, reinforcing its position as the principal driver of new deployment.

This concentration gives developers, EPC contractors, and equipment suppliers a measurable priority. MVA Pulse reported that demand for modules, inverters, and balance-of-system components remained at an all-time high. In that environment, project-execution speed and supply-chain resilience become more consequential than broad enthusiasm about renewable growth.

Concentration defines the next test

The geographic distribution was almost as striking as the technology mix. Asia contributed 514.1 GW, or 74.1% of all new renewable capacity added in 2025. Europe added 77.4 GW, while North America added 42 GW.

For India, the figures point to a highly competitive global supply chain alongside rapid domestic and regional expansion. The practical constraint is shifting from whether renewable projects can be built quickly enough to whether transmission, grid infrastructure, and energy storage can accommodate rising volumes of variable generation.

The next proof of progress will therefore be paired: capacity must continue to expand, but grid infrastructure and storage must keep pace. A larger renewable fleet is tangible progress; managing its output reliably is what converts capacity into durable system-wide change.
