Here is the study where that figure was calculated from. Refineries are, at best, 90.1% efficient, considering all inputs and outputs. If you exclude less desirable outputs like road oil and asphalt, efficiency is more like 86.4%, with refineries purchasing 39.3 TWh of electricity and 34,000 short tons of coal to produce even more.
