Time Passes...Coal is Discovered Again - by Us
     Coal consists of a complex range of material, and coal from one deposit may vary greatly from that of another. These difference can result from the type of organics, the depth and duration of burial, and the heat it was exposed to. These things will all affect the heat value, carbon level and the amount of contaminents of the final product. This coal is then used to heat homes, to create electricity, for metallurgic purposes or to produce synthetic natural gas.
