Except for solar electric panels and petroleum-powered engines, man-made power is produced by heat-powered turbines.
This means that wood fires could power turbines as well as wood stoves to produce either electricity or mechanical power.
Unless someone can show me an inorganic process that is used in Nature to make oil, then the logical conclusion is that oil is a renewable organic product. This would mean that petroleum is made the same way all other fats and oils are made, by organic life.
Some people were saying that people will have to eat bugs because of changes in the weather. This idea disregards the fact that organic pests can be harvested for their oil.
Only life produces oil, which would make oil a renewable energy source.
