Coal's energy density is a little more than half of petroleum. Multiple products can be produced from petroleum, unlike coal. Petroleum is also much easier to transport. You can even run petroleum through a pipeline.
I'm not saying coal isn't useful, but petroleum is far more useful.
Coal is pretty useful. The rest of it, not.
