Solar power includes solar farms as well as local distributed generation, mostly on rooftops and increasingly from community solar arrays. In 2024, utility-scale solar power generated 219.8 terawatt-hours (TWh) in the United States. Total solar generation that year, including estimated small-scale photovoltaic generation, was 303.8 TWh. As of the end of 2024, the United States had 239 gigawatts (GW) of installed photovol
82% of U.S. energy comes from fossil fuels, 8.7% from nuclear, and 9.1% from renewable sources. In 2023, renewables surpassed coal in energy generation. 1 Wind and solar are the fastest growing
In our STEO forecast, utility-scale solar is the fastest-growing source of electricity generation in the United States, increasing from 290 BkWh in 2025 to 424 BkWh by 2027.
California has led the USA in photovoltaic installations, producing the largest share of utility-scale solar electricity generation at 25.5% in 2024. Within the state, photovoltaics accounted
Despite being around for nearly 150 years, solar energy has remained a fringe source of power generation in the United States due to its historically high costs and lower efficiency compared
In 2024, 66% of all new electricity generation capacity in the U.S. came from solar. [3] The United States conducted much early research in photovoltaics and concentrated solar power.
