In short, No. Coal comes in the middle of the pack when fuels are compared. Propane produces 21500 BTU per pound, Gasoline 17500 BTU per pound, Coal between 12,000 BTU per pound (Anthracite) to 10,000 BTU per pound (Bituminous) and wood (dried) 7000 BTU or so. On the other hand, Coal can be converted to Gasoline using a process developed during WWII, or to Methane (modern) or to "Town Gas", a mixture of Hydrogen and Carbon Monoxide.

Not sure if this will answer your question, but I'll give it a shot. It's less about the fact that is is coal and more about the fact that coal gives off heat.

So really the origin of the energy is in the heat that the coal generates when on fire and less about the coal itself.
