Thinking out loud about oil - oil is one of those things where the costs of production and the costs of use are immeasurably huge and in no possible way captured by a modern price-point or market place.
Life had to sift carbon from the air with the help of the energy of the sun, then be enveloped by the Earth, and cooked and crushed - a process that takes longer than humans have ever existed, and maybe used more raw source energy than we may have ever used, and certainly more than we could ever get back from the oil.
Then we evolve in an atmosphere of lowered oxygen and carbon and we go through the process of returning the carbon back to the air, all the while facilitating our own lives. Meanwhile hoping that we'll find a method that uses much, much less energy, to put all that carbon back into the ground. Or, more likely, simply kicking the can down the road for when the problem becomes appreciable to people.
edit: it's funny, look at this hockey stick graph https://en.wikipedia.org/wiki/Geological_history_of_oxygen https://en.wikipedia.org/wiki/Great_Oxygenation_Event
edit: I guess I'm saying that price points and the market are pretty short sighted in the scheme of things.
