That appears to be total energy, rather than grid specific (per the parent). This is probably a better reference (the gist is the same of course, coal was 19.5%): https://www.eia.gov/tools/faqs/faq.php?id=427&t=3 https://www.eia.gov/tools/faqs/faq.php?id=427&t=3 "In 2022, about 4,243 billion kilowatthours (kWh) (or about 4.24 trillion kWh) of electricity were generated at utility-scale electricity generation facilities in the United States.1 About 60% of this electricity generation was from fossil fuels—coal, natural gas, petroleum, and other gases. About 18% was from nuclear energy, and about 22% was from renewable energy sources."
