But you said “cheaper,” additionally this ignores the input fossil energy of the gasoline, and it’s per joule of thermal energy, not useful mechanical energy. It’s a weird metric that isn’t very enlightening. It’s mixing low-entropy electrical energy with high-entropy thermal “primary energy.” It’s also not what you actually said. The cost of energy (as well as emissions) per mile traveled is far, FAR less in electric vehicles. |

1. Emissions from initial production
2. Emissions from fuel production
3. Emissions from fuel consumption
For EVs, emissions from 1 and 2 are higher. But this is more than offset by having 0 emissions from the third category. So yes, the emissions per mile traveled is less in EVs. However the cost of fuel production per mile traveled is still significantly higher (around 192% higher)
PS you're the only one who used the word "cheaper". I only used it when directly quoting you. I presumed we were still measuring by emissions and not by dollar cost, but I see now that you were talking about something else
EDIT: check out figure 4.6 on page 68
