I don't see that there is that much money in the Anthracite system for price reductions. The question for me is what would be the switch price of a half way decent bit coal delivered to my door over premium anthracite. Even if the coal was free, transportation would make it a non decision.
Sometimes you have to pay for quality and it's worth it, you know like when you buy a GM car.
Maybe this is true in respect to power generation, but out here in PENNSYLTUCKY we dont got no natural gas availability for home heating needs. Anthracite is the best fuel source I have availability too!
