As of October 2024, China, United Arab Emirates, and India have taken over as the leading developers of large-scale solar power projects.
U.S. demand for solar power is surging despite an economic recession, thanks to government financial incentives, some easing in credit availability, and increasing public recognition of its environmental benefits.
Although the largest utility-scale plants are outside the United States, the USA plays a significant role in residential and commercial solar development.
