On climate strike day (Friday) I rode the e-bike from town to my summer camp, 30 miles 77 hills. Mostly pedaling, I used 75 watt hours. (4.5 volts on 48 v 17 AH battery) That is .075 KWH or at the $.158 a KWH I pay, .01 cent. I probably did more damage to the climate with the food I ate than with the electric motor.
