Well... nobody seems to care that the electricity for EVs comes from fossil fuels as well (for now).
The question is what is the efficiency difference for both?
If a fossil fuel powered electricity plant generated energy driven car is still 5 times more efficient than an ICE it still is beneficial. I would like to see those calculations.
Well that one is easy calculation.
EV typical consumption is 18 kWh/100 km, coal plant typical CO2 emission is 950 g/kWh so that makes 171 g/km if you charge your EV from coal plant. Equivalent to approx 7 l/100km gasoline consumption.
Avarage CO2 emission in Germany is 600 g/kWh so that means 110 g/km emission.
Here it is 90 g/kWh so only 16 g/km emission, way better than gasoline car.
