I provided links showing electric motors are more efficient than gas motors.
Do you have any evidence to the contrary?
And how efficient are the power plants that generate the electricity? Make sure you include transmission losses.
In post #21 I shared this link & info:
from: All-Electric Vehicles
"Energy efficient. Electric vehicles convert about 59–62% of the electrical energy from the grid to power at the wheels—conventional gasoline vehicles only convert about 17–21% of the energy stored in gasoline to power at the wheels."
I think the difference between 59-62% and 17-21% allows for quite a bit of transmission losses. And I am fairly certain that a large coal generating plant is far more efficient that hundreds of thousands of tiny combustion plants with questionable maintenance.
The most efficient coal plants are less than 40% efficient. So right off the bat you've got 0.40 X 0.60 = 0.24 or 24% by the time the energy gets to the road, and that doesn't include transmission losses, battery losses or any other losses.
