What's going on: Electricity generation from solar power totaled approximately 4,260 billion kilowatt hours in 2025, and that number is expected to grow by 1. 6% in 2027, the EIA says in its latest “Short-Term Energy Outlook” projection. Wind power took first place as the strongest net electricity producer, followed by photovoltaics, which increased its production by 21 percent in 2025 and overtook. Electricity generation by the U. 9 percent, down. Recent policy changes are expected to affect the pace at which solar PV capacity is added annually through the end of this decade. Even so, low costs, faster permitting and broad social acceptance are set to continue to drive the accelerating adoption of solar PV. Growth in utility-scale and distributed solar PV more than doubles, representing nearly 80% of worldwide renewable electricity capacity.
