Solar potential Insolation map of the United States with installed PV capacityĪ 2012 report from the National Renewable Energy Laboratory (NREL) described technically available renewable energy resources for each state and estimated that urban utility-scale photovoltaics could supply 2,232 TWh/year, rural utility-scale PV 280,613 TWh/year, rooftop PV 818 TWh/year, and CSP 116,146 TWh/year, for a total of almost 400,000 TWh/year, 100 times current consumption of 3,856 TWh in 2011. Governor Jerry Brown has signed legislation requiring California's utilities to obtain 100 percent of their electricity from zero-carbon sources by the end of 2045 (including 60% renewable energy sources by 2030). Hawaii plans 100% renewable-sourced electricity by 2045. Many states have set individual renewable energy goals with solar power being included in various proportions. There are plans to build many other large solar plants in the United States. solar plant with molten salt thermal energy storage. When commissioned it was the largest parabolic trough plant in the world and the first U.S. The 280 MW Solana Generating Station is a solar power plant near Gila Bend, Arizona, about 70 miles (110 km) southwest of Phoenix, completed in 2013. The Ivanpah Solar Electric Generating System is a solar thermal power project in the Mojave Desert, 40 miles (64 km) southwest of Las Vegas, with a gross capacity of 392 MW. The oldest solar power plant in the world is the 354-megawatt (MW) Solar Energy Generating Systems thermal power plant in California. It is among the top countries in the world in electricity generated by the sun and several of the world's largest utility-scale installations are located in the desert Southwest. The United States conducted much early research in photovoltaics and concentrated solar power. In 2020, more than 230,000 Americans were employed in the solar industry. By 2015, solar employment had overtaken oil and gas as well as coal employment in the United States. In 2021, 36% of all new electricity generation capacity in the country came from solar, surpassed only by wind with 41%. This capacity is exceeded only by China and the European Union. Īs of the end of 2022, the United States had 142.3 gigawatts (GW) of installed photovoltaic and concentrated solar power capacity combined. Total solar generation that year, including estimated small-scale photovoltaic generation, was 204 TWh. In 2022, utility-scale solar power generated 145.6 terawatt-hours (TWh), or 3.4% of electricity in the United States. Solar power includes solar farms as well as local distributed generation, mostly on rooftops and increasingly from community solar arrays. Solar panels on a rooftop in New York City
