Electricity used to refine each barrel of oil in the US in 2016: 47.388 billion kWh / 7.21 billion barrels = 6.6 kWh/barrel
If I am not mistaken, I think what really skews the results in big oil's favor is that the main source of heat for the refining process isn't electricity, its the burning of gas or petroleum, right? So, *technically* they make it look like not much energy is being expended to refine a gallon of gasoline, because they are only including "purchased electricity". If that is true, its not an apples-to-apples comparison. I would like to see true refining costs that include the total amount of energy used for refining, not just bought electricity. Hell, since that quoted info specifies "purchased electricity", a refiner could have a diesel-powered generator onsite making electricity for refining, and that electricity wouldn't be included in these calculations.
