Yeah right. Except for the fact that electric cars are a lot more efficient than internal combustion. One twit being interviewed by a bunch of other twits doesn't change that.
Forgotten a few things? Yep you did.
The power generation process is inherently inefficient, depending on the type of plant.
I am ONLY counting fuel-based power plants, since cars get charged overnight. The sun is "pretty much not around" at night, and even the wind is generally lower at night. Wind power is damn close to a hoax right now anyhow.
So, the power plant struggles to get close to 50% for the best ones with a "topping" cycle added to the regular steam. That is to get mechanical energy. Call that about 48%.
Generation is not 100% efficient, probably around 95% at best.
Transmission of energy to the usage point is about 90% efficient, in general.
The charger and charging process varies from 80% to 90% efficient in getting energy into the battery.
Now, the inverter that produces AC for the vehicle motor is about 97%
The motor in the vehicle is about 90%
Getting current out of the battery produces heat, efficiency is maybe 97% at "average" current draw.
There are other incidental losses amounting to a few percent here and there, which we can just leave out for now.
Getting this all multiplied out, and taking the better efficiency, even though it is not likely to be the average.....
What we get is a net of about 35% in the process up to storing energy in the battery.
Now, using that energy from the battery drops the overall efficiency in terms of producing motor torque/power to about 29%.
It is certainly not impossible to get a 29% efficient IC engine. many are miles ahead of that.
I could include the energy cost of delivering the fuel, but we did not do that for the power plant either.
