I think from just the very chemistry of oil we can't reduce it's value enough to stop using it. The chemical processes that created it have sequestered massive amounts of energy from the past, energy that we can still use in the future, energy that we don't need take out of our future budgets. Even a space-faring species would take advantage of oil if they deign to enter a planet's gravity well.
