According to the International Energy Agency (IEA), the share of solar power is up from 5% to 7%. The IEA expects global PV module generation to increase by 1,800 TWh per year between 2025 and 2027, causing solar to become the second-largest renewable energy source after wind. . Renewables We expect renewable power generation will increase 12% in the United States to 1,058 billion kWh in 2025 and increase a further 8% to 1,138 billion kWh in 2026. Renewable sources were the second-largest contributor to U. power generation in 2024 and accounted for 945 billion kWh, up 9%. . In 2023, PV represented approximately 54% of new U. electric generation capacity, compared to 6% in 2010. Solar still represented only 11. However, 22 states generated more than 5% of their electricity from solar, with California. . Big solar generation grew by more than 58% in January versus last year, with all types of photovoltaics delivering just over 5% of the nation's electricity. In absolute terms, solar growth reached 475 TWh, which is comparable to annual power consumption in France or Germany.
