It looks just like I suspected: the whole EV thing efficiency estimations are just one more scam, omitting critical considerations.
The Norwegian Illusion: EVs Are Not More Energy Efficient
2024-03-22
...If our models are correct, EVs will fail on two fronts: they are less energy efficient than the ICEs they are trying to replace and their adoption will do little to mitigate carbon emissions.
... Most articles list EVs as anywhere between two and three times more energy efficient than the ICEs they replace.
The basis for this claim is that internal combustion engines are only 40% efficient and that nearly 60% of the energy contained in gasoline or diesel fuel is “wasted,” –mainly in the form of heat and friction. On the other hand, an electric motor transfers nearly 90% of its electrical energy directly to the wheels. The difference leads many to erroneously conclude that an EV is almost three times as “efficient” as an ICE.
This common argument is fundamentally flawed for three reasons.
First, it fails to capture the energy needed to make the battery;
second, it fails to distinguish between thermal and electric energy;
and third, it fails to account for the poor energy efficiency of renewable energy.An EV uses 32 kWh of electricity per 100 miles traveled. The vehicle’s battery, meanwhile, consumes an incredible 24 MWh in its manufacturing. Assuming a useful life of 120,000 miles, the battery pack consumes 20 kWh per 100 miles traveled, two-thirds as much as the direct electricity itself. Most analysts we have read fail to include this onerous energy burden when touting the EV’s superior efficiency.

WIND: and this article doesn’t even count the wonderful waste heat of an ICE as a feature—a major feature—when used in winter in cold climates.
