Spring 2023 Solar Industry Update

. 2022 U.S. Generation and Capacity Renewables are becoming an increasingly large part of the U.S. electric generation mix, representing 28% of capacity and 23% of generation in 2022. - Adding nuclear, non-carbon sources represented 36% of capacity and 41% of generation. 2022 U.S. Generation (Total 4,302 TWh) • • Solar still represents a small but growing percentage of the U.S. electric generation mix. - In 2021, solar represented 9.0% of net summer capacity and 4.7% of annual generation. Capacity is not proportional to generation, as certain technologies (e.g., natural gas) have lower capacity factors than others (e.g., nuclear). 2022 U.S. Generation Capacity (Total 1.2 TW) Geothermal.
