Solar generation was 3% of U.S. electricity in 2020, but we project it will be 20% by 2050

According to our Electric Power Annual, solar power accounted for 3% of U.S. electricity generation from all sources in 2020. In our Short-Term Energy Outlook, we forecast that solar will account for 4% of U.S. electricity generation in 2021 and 5% in 2022. In our Annual Energy Outlook 2021 (AEO2021) Reference case, which assumes no change in current laws and regulations, we project that solar generation will make up 14% of the U.S. total in 2035 and 20% in 2050. These data include electricity generated from both utility-scale (those of 1 megawatt or more generating capacity) and small-scale (less than 1 megawatt) solar facilities in the electric power, residential, commercial, and industrial sectors.
