Renewables drove 2025 growth
What happened
Renewables made up 86% of the world’s new generating capacity in 2025, with solar accounting for nearly three‑quarters of that expansion. (arstechnica.com) The trend is already reshaping grids and household economics — the UK hit a record 52.5% renewable electricity in 2025, and plug‑in solar is estimated to save a typical UK family about £1,100 over 15 years.

Why it matters
Last year’s buildout added roughly 692 gigawatts of new renewable generation capacity worldwide, with solar alone contributing about 510 gigawatts and total renewable capacity rising to roughly 5,149 gigawatts. (esgtimes.in) ( ) Deployment was heavily concentrated: China, the United States and the European Union together accounted for about 550 gigawatts of the 2025 additions, so most of the expansion came from a handful of large markets. (esgtimes.in) Solar’s dominance in new builds reflects two concrete economics: module and project costs are near record lows, and solar projects take months rather than years to permit and construct, making them faster to deploy than many other technologies; the International Energy Agency notes low costs and faster permitting as primary drivers of solar growth. (The levelized cost of electricity, a project’s lifetime generation cost per unit of electricity, has been especially favorable for solar.) (iea.org) ( ) Grid-side changes are keeping pace: battery storage installations surged, with the United States installing a record 18.9 gigawatts of battery capacity in 2025 and utility-scale storage pipelines expected to deliver another 18+ gigawatts soon, which helps smooth the variability that comes from more solar and wind generation (battery storage refers to large electrochemical systems that store electricity for use when output from wind or solar falls). (woodmac.com) ( ) In the United States specifically, solar and storage together accounted for the vast majority of new utility-scale capacity in 2025 and the solar industry installed roughly 43 gigawatts last year, reinforcing a pipeline that is shifting investment and supply chains toward panels, inverters and storage equipment. (pv-magazine-usa.com) ( ) Policy and manufacturing data show what that means for costs and markets: analysts report wholesale solar module prices clustered near about ten cents per watt (a raw equipment price metric), and that improved domestic manufacturing and tax‑credit timing are key reasons firms accelerated projects into 2025.
