Some folks in parts of the world are very reliant on gasoline, while some are more dependent on electric. Petroleum based products however are still in absurd demand by almost all parties. How do you stand to fair if the oil situation continues to worsen? Plastics. Nylon. Jet fuel. Tires. Asphalt. To name just a few things that heavily rely on oil byproduct.
To be fair, for most of the applications of oil it’s not so much that it “relies” on oil, just that it’s the cheaper method (for now).
You can make a plastic bag starting from water and carbon dioxide (or some other source of carbon), plus electricity.
