US Steam Coal Price Up again last week.
But all five US coal price indices are still much cheaper than the world price of $155./ton
Appalachia coal (which is eaiest to export) is now cheaper again on a mmbtu equivalent
basis ($3.70) than natural gas ($3.67)
Some of the gas to coal switching over the past couple months should start switching back to gas at these prices.
