I heat and cool a 3400 sq ft house(basement and main floor) and my electric bill is rarely over $200 a month and everything here is electric. Between the two kids and wife, there is nothing left turned off.
So with a well insulated garage, I could see that as a possibility. Assuming of course he doesn't leave the doors open.
1700 SF stacked above one another is a far cry from 4800 sf with 16' ceiling heights. He is heating roughly 6 times what you are given all heat lost from a basement goes to the first floor. Overhead doors are also notoriously bad at air infiltration. Maybe his shop is located above a spent uranium depository.
