I wonder if they add *all* the energy used by the refinery; for things like pumps, lights, secondary systems, etc. If they are basing it on the overall numbers of energy used by a refinery:
34kWh * 15.4% = 5.236kWh per gallon. Which is enough to drive 20 miles at 250Wh/mile or ~34.9 miles st 150Wh per mile. That's just the refining. If they are only adding the energy directly used in refining, then that is not accurate.
Let's not forget that if electricity is to be penalized for the losses to generate and for the grid, then the refinery has to add that embedded carbon into the gasoline. And the other stages of oil exploration, extraction, transportation, storage -- also add more energy, and each of those added energy have their own overhead of embedded energy, too.
