Oil is a more widely distributed resource than coal.
Explanation:
Oil and natural gas are two of the most unequally distributed resources in the world and these are depleting as far the coal reserves.
Thus they are not widely distributed as most of the oil reserves occur in the Arabian peninsular and the middle east region and other parts of the world including the Eurasian and arctic areas.
Apart from that, the oil reserves are located in the oceanic depths and thus there extraction and drilling process is not an easy task. Similar to that of the coals reserves.
