> This report also analyzes prospective generation capacity in four categories — under construction, permitted, application pending, and proposed. More than 466,000 MW of new generation capacity is under development in the United States — a 13% increase over 2022. Sixty-one percent of capacity most likely to come online, permitted plants and plants that are under construction, are in solar.

China's growth in power capacity is non-trivially due to increasing demand. If the US or Europe or wherever suddenly wanted to build XXX GW per year, they could (modulo bureaucracy, which is very real).
