Solar power includes solar farms as well as local distributed generation, mostly on rooftops and increasingly from community solar arrays. In 2025, utility-scale solar power generated 295. 7 terawatt-hours (TWh) in the United States. In our latest Short-Term Energy Outlook (STEO), we expect U. electricity generation will grow by 1. 6% in 2027, when it reaches an annual total of 4,423 BkWh. In 2025, net generation of wind and solar together accounted for 760,000 gigawatthours (GWh) of electricity, 88,000 GWh more. This map provides information about all of the solar photovoltaic (PV) manufacturing facilities in the United States and how they contribute to the solar supply chain. The electricity grid is a complex machine in which electricity is generated at centralized power plants and decentralized units and is transported through a system of substations, transformers, transmission lines and distribution lines that deliver the product to its end user, the consumer.
