Solar power generation drives electricity generation growth over the next two years ›

Electricity generation by the U.S. electric power sector totaled about 4,260 billion kilowatthours (BkWh) in 2025. In our latest Short-Term Energy Outlook (STEO), we expect U.S. electricity generation will grow by 1.1% in 2026 and by 2.6% in 2027, when it reaches an annual total of 4,423 BkWh. The three main dispatchable sources of electricity generation (natural gas, coal, and nuclear) accounted for 75% of total generation in 2025, but we expect the share of generation from these sources will fall to about 72% in 2027. We expect the combined share of generation from solar power and wind power to rise from about 18% in 2025 to about 21% in 2027. More ›
