According to the EIA electric transmission losses are 7% average
nationwide (5.5% here in IL) and are based on total production +
imports - direct use -watts sold. So it would include losses at
stepdown to 220.

This analysis neglects the differences between the qualities of energy
sources. Coal won't fuel a car directly, it's only good for making
steam . Petroleum is more versatile. Electricity is the highest, most
valuable form which can do almost anything except be stored cheaply in
bulk..
