Do not underestimate what can be done without oil. The French island of Guadeloupe (in the Caribbean) exported 24,400 metric tons of sugar in 1762. This was done with organic farming and human labor. The sugar was exported in wooden sailing ships. No fossil fuels were involved.
The catch was that 80% of the population of 50,000 were slaves.
Be that as it may, most of the sugar was used to create ethanol. As we know, ethanol is a good fuel for automobiles and airplanes.
One of the problems of the world now is too many people. Easy to imagine what the people will be expected to do when the oil is gone.
For people who object to being enslaved (see the bankruptcy bill) there is always the thermal depolymerization plant. Soylent biodiesel is people.
