I think this says it all.

A word of caution, though. The magnitude of the problem facing this country has another dimension that should not be underestimated. At the peak of their synthetic fuel production in 1943, when half of their economy and their armed forces ran on synthetic fuel, the Germans produced 36,212,400 barrels of fuel a year. At current rates of imported fuel alone, that quantity in this country would last all of four and one-half days!
