Once or twice a week. Tried with the eTron and its silly, it adds 1 hour or more for waiting for a station and actually charging.How often do you drive over 210 miles in a day? For me, that's once or twice a year. Also, we have solar panels.
I have various 5, 6 and 10 cylinder ICE on the stable. Also 3 feet of foam insulation on a poured concrete home with 24 SEER hvacs, all LED lights.
Work has taken me to many lithium, copper, gold mines and countless power gen facilities. No further comments required.
