I think you underestimate how widespread petroleum derivates are outside of energy. Construction materials, roads, tires, plastics, cosmetics, cleaning products, paints, inks, dyes, adhesives, sealants, lubricants, clothes, waterproof fabrics, batteries, fertilisers, medicine, tooth paste, shampoos, &c.
It's _the_ building block of modern life, unless you're in nature you can bet everything you lay your eyes on is at least partially made of petroleum or its derivates
Eh. We can usually use modern chemistry to instead start from natural oils or fatty acids instead of dinosaur juice for most of it. If we cannot outright replace the problematic substance.
Some energy input may be required. ( But likely on par with current diesel/gas processing.)
