    Advantages and Disadvantages of Coal Mining and Use,  · Among these are reduced carbon emissions, reliable long-term energy production, and higher long-term economic output. Also, if the coal eventually depletes, it is possible to use the same facilities to provide other sources of power to the same population at any given time. 4. Coal is convertible to various formats.What Are the Advantages and Disadvantages of Using Coal?,  · The advantages of using coal: Coal is an inexpensive form of energy.
