The first cars Henry Ford made, ran on ethanol and the oil barons convinced Ford to switch to refined petroleum gas.
Peaking and running out are not the same thing Mary. We will have decades to reverse our global consumption trends. I Believe environmental concerns will continue to drive a reversal of dependency on geologic oil as they are starting to. This trend can, and probably will coincide with supply side pressure increases.
We do not, and we have never needed geologic oil to power our modern world. It is definitely not worth any kind of stress about, other than your personal economics and wild-assed war starting policies. A few billion dollars will be invested in the next 2 -5 years to modernize (algae) plant oil fuel manufacturing. Algae oils are low/no pollution and as oil production costs rise they become competitive..
Guess who said the following and when:
"The use of vegetable oils for engine fuels may seem insignificant today, but such oils may become in course of time as important as petroleum and coal tar products of the present time."
