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
