A review by the SUN DAY Campaign of four reports released in December by the Federal Energy Regulatory Commission (FERC) and the US Energy Information Administration (EIA) reveals that solar has grown faster in electrical generation than all other energy sources as well as outpaced them in new US generating capacity added during the first 10 months of 2023. However, to meet climate change goals, there remains a need for much faster growth by solar and all other renewable energy sources.
