A core trait of my personality can be summed up as "always look on the bright side of life". To that end: This war seems more than likely to drive up oil prices not only in the near term, but in the medium and long terms too! In addition, petroleum usage seems likely to become dependant on sucking Iran's proverbial dick, a notion that very few people in The West will find palatable. Optimistically then, perhaps this…
this misses the fact that petroleum is incredibly useful outside of the burn it to make electricity and burn it to make car move use cases.
We can probably stand to use a lot less plastics too. Outside of medicine it's mostly replaceable, and reducing our usage to less than 80% of current usage would be trivial if we didn't burn it for energy.
In that scenario Iran can keep their strait. We won't need them.
