Okay, I think I get it -- they add the "losses" of the petroleum fuel to the energy in a gallon of fuel, and then take a percentage of that and that is the electrical equivalent? So:
1 gallon (of generic gasoline) = 13.4 kWh?
That seems a little skewed, still. That means that electricity has ~3X more losses than the whole petroleum cycle?
Lately, I have heard that petroleum exploration is ~15:1 ROI, and I have heard that the power used on refining alone would be enough to power EV's. Maybe, I'm wrong?
What are the grid losses, typically? I thought I heard it was only 10%; though a while ago, I had heard ~50%...
And they are not counting oil spills, probably?
