The low cost of coal is what provides the low cost electricity for our computers and internet access. Blue gem coal (from E TN and SE KY) is used in the production of semi-conductors used in our computers. While this is a terrible environmental tragedy, it will be monitored and it will be cleaned up. Without the use of coal and the resulting low cost electricity, much of the economy in the south and southeastern US would be non-existent. Just my two cents worth and no, I don't work in coal or TVA.
