2) So yeah, difference in total emissions from an EV in Alberta vs Quebec or Ontario is going to be very different, but that doesn't change the fact that even with our power mix, and high use of fossil fuels, an EV in Alberta will still produce fewer emissions overall than an ICE, because a large power plant has a much better thermal efficiency that an ICE, even with transmission and charging losses

It is my understanding that thermal power plants have about ~40 percent efficiency
Transmission losses are around 10-15%
Say the EV has 85% power to wheels
So that would put you around 30 percent
I don’t think that is much better than an ICE, particularly if the ICE is supplemented in a hybrid with regenerative braking contribution
