Solar power has become the leading renewable source in global electricity generation, overtaking wind for the first time
Executive summary: Global solar photovoltaic generation surpassed wind generation in 2025, making solar the top renewable electricity source for the first time. The crossover signals a structural change in the power sector, influencing capacity investment, grid integration strategies, and the economics of complementary firm power such as nuclear and storage.
Who is involved: Key actors include major solar manufacturers (e.g., First Solar, JinkoSolar, Trina Solar), wind OEMs (Vestas, GE Renewable Energy, Siemens Gamesa), global utilities, and policy bodies such as the IEA, EU Commission and U.S. Department of Energy.
Likely next: Analysts expect the IEA World Energy Outlook (October 2026) to revise renewable share forecasts, while COP30 (November 2026) may highlight solar's role in meeting 2030 climate targets. Quarterly earnings from solar and wind majors in Q3 2026 will provide early market signals.
According to OilPrice, 2025 data show solar photovoltaic output exceeding wind generation worldwide, marking a historic inflection in the renewable energy mix. The milestone reflects years of steep cost declines for PV modules and rapid deployment in China, the United States and Europe. While wind remains a major contributor, the shift underscores solar's growing dominance in new capacity additions and its implications for grid planning, storage demand and investment flows.
