The mix will fluctuate on a day-by-day basis. You could be 100% renewable on one day, wind solar, and hydroelectric (although that’s problematic in and of itself) with the inevitable nuclear for base load.
The next day you could be still and overcast and you’ve already used all of your water from the dam so you have to run more natural gas in the mix.
To pick any random day and to say that that date is representative of the year as a whole is silly, you need averages over the course of a year.
