You will get no argument from me, Sting. Wood should have about 8,000 BTU per pound, anthracite 12,000 or 13,000 depending whose numbers you accept, and I don't know about bituminous. If I could buy good wood pellets at $150 like you can, I would not be burning coal at $300. It seems to depend SO much on where you live. I am in Maine, which has a lot of trees, and yet wood pellets are about $240, way more than your area of Wisconsin. And pellets here are sometimes plentiful, sometimes scarce. But if I were in Pennsylvania and could buy coal for $130 at the breakers, there is no way wood pellets could compete.
I will agree with others, though, that when cost per BTU is fairly close, coal has an edge in easy storage, much lower stove cost and stove/chimney maintenance if you go with hand-fed which is not an option with pellets, and probably lower air emissions.
