OK, but the headline is "solar and wind to top coal power in US for first time", not "solar and win to top coal power in places /u/hermitcrab saw in Florida", right? "I didn't see any in Florida" was a very odd rebuttal to the article's factual content.
The answer to your question "So where does this US solar and wind power come from?" is "mostly not Florida".
If you drive around the UK you see lots of solar. On people's houses (maybe every third house in the town I live in) and in fields beside the roads.
