It seems as if we might be better off...
...using oil for things that do not require the oil distillate to be carried from place to place. Our vehicles carry both gasoline and a heat engine, neither of which is particularly light and for safety we place ALL these things as well as ourselves inside a steel body when the goal was to simply be somewhere else only to turn around and go home again.
This is crazier then growing a lawn that you have to mow to enjoy.
