It’s very silly i know, but I have no idea why petroleum (or other substances) is so important for our industries to work. Why/how can it give us “energy” ?
And why coudn’t “flowers” or “sounds” or “colors” (or anything else) give us energy instead ? I don’t understand how “energy” works at all…
Edit: i don’t even know what flair to put… ( Chemistry ? Ingeeniring ? Biology ?)

The molecules most fuels are made of are very reactive. Meaning, they’re held together with a lot of energy. However, unlike other molecules held together by a lot of energy, it’s really easy to break apart molecules in fuel. All it takes is oxygen and a bit of heat. The resulting molecules don’t consume much energy to form, so the leftover energy is released as heat.
Most other materials that can’t be used as fuel either aren’t as reactive or don’t release as much energy when burned
