You are conflating energy equivalence with carbon footprint.

1 gallon of typical gasoline = 33.4kWh of electricity.

If you are applying all the embedded energy for electricity, then you also need to do the same for gasoline. Gasoline has emissions from the tailpipe *and* from the refinery, and the wellhead, and from the transportation. Electricity has it from the source and the generation stage. All use of carbon for both must be counted in order for the comparison to be fair.

Because, if I have solar panels on my roof, or a wind turbine in my yard, then your numbers are no longer accurate. I'd like to see someone try to refine gasoline from oil at home!
Sincerely, Neil
