You are not accounting where the energy came from.

> Fossil fuels generate about 60% of U.S. utility-scale electricity
If we are being generous, these power plants are around 50-60% efficient.
Motor vehicle engines are around 35-45% efficient.
If you actually go do the math and account for all the losses during each step of conversion and transmission, I think you would find that they are much closer to each-other than you think.
You have to compare energy usage all the way back to the source, otherwise you are throwing vital information.
