I would agree with your fact about coal, if you totally ignore that the easiest-mined coal has already been removed from the ground. Plus we don't know how much we have left, since determining the location and depth and size of a coal seam requires drilling into the ground. which is time-consuming and expensive and that only proves reserves, you still need to get the coal out of the ground. And coal is hardly ready for use out of the ground. You get to remove rock and dirt. Then you get to wash and blend the coal depending on your target market. Finally you get to deliver it, so you have to somehow find a barge or rail line close enough to make it econimically feasable to mine the stuff in the first place. But otherwise, great point about coal.
