Do you have this in text form, or can you tell me where my numbers went wrong? The math is simple and the numbers behind it are all pretty easy to find. Sure, it depends on the kind of car. A Tesla running on 100% coal is not as good as a first-generation Honda Insight. But if you compare similar cars then electric is at least at parity (for unrealistic 100% coal grids) and typically way better. |

He compares pretty much the same car, from the same (French) maker, but with one version of the car running on Diesel, and one electric. You can see already that in half of EU countries, including Germany, running a gas car is better than an electric one.
Not sure how that does work out in the US, but given that 2/3 of electricity mix in the US are from fossil fuels (from which about 40% coal), you should be closer to Poland. So essentialy, depending on the state where you drive your Tesla, you could be better off with gas powered car (in terms of CO2 emissions).
