Class A is fine, compared to other items in the home there is little impact.
The big Evil is EV i had a Tesla S and their SUV and my electric bill went up $600 a month, the dial on my meter was moving so fast there was a constant whine. So i installed solar and two Tesla house batteries to the tune of 70k and my electric bill was still in the $200 a month range. I got rid of the Teslas and now the electric company is paying me monthly.
For everyone to be in an EV is a pipe dream the grid cannot handle what we have now let alone an EV world. So if someone complains tell them to complain to an EV owner.
