Quite an interesting study.

Btw, energy losses between the powerplant and the consumer are 10-15% on average. Battery charging losses (heat..) are from 15% upwards - depending on charge power (the faster the charger- the higher the loss..). Add to that discharging due to environmental temperature (can go up to 70%..), battery capacity loss (due to age/number of charge/discharge cycles), etc, etc.
