This is not to say it is more or less efficient. But if you want to point out energy loss when charging, you need to look at the energy expended to pump gas.
It becomes a pretty complicated endeavor, so MPG and MPGe are used.

People weren’t talking about how much energy is lost. I simply pointed out the $14 story isn’t true. But now that we are talking about energy losses, over 60% of energy is lost just during electrical generation. For the math-challenged that’s significantly more than 24%. And doesn’t include the losses in transmission, in the home, etc.
