Not exactly comparable, if the electricity comes from burning fuel then those losses are at the power plant + transmission losses + losses in the car and drivet

Not exactly comparable, if the electricity comes from burning fuel then those losses are at the power plant + transmission losses + losses in the car and drivetrain.
power plants are generally more efficient than small combustion engines but all other things in chain must apply. Mix in nuclear and solar and things change of course.
However comparing the efficiency of the controller / motor to engine / transmission is apple to oranges, the battery / controller / motor in a EV is just the last part of a long transmission stretching from the engine in the power plant:

- speedgoose 6y agoYes it's difficult to compare. Many people like to take into account the efficiency of the electricity production when talking about EV, which is an important thing to do, but forget that gaz does not appear magically in a gaz tank. The efficiency of having gaz in a gaz tank is shit. I don't have the numbers because I'm lazy, but I remember reading that it takes more energy to bring one liter of gaz in a car tank, if you consider the full chain, than the energy required to drive a EV on the same distance. So even before you start to turn on the cars, an EV has used less energy.
