Aren't all of those things only a tiny fraction of our oil usage though? The entire global plastic industry accounts for < 5% of the oil we dig up IIRC. The vast majority is turned in to fuel.


Likely true. However that will need to last us a long time. 5% of oil is still a very large industry.

We make renewable ethanol from agricultural products entirely dependent on fossil fuels.
