And we are also burning your coal, mined and exported across the atlantic because it can't compete with your cheaper fracked gas. And even some of your biomass in the name of saving the planet and at the cost of my taxes.
Maybe it is Petroleum Coke? From Petroleum Coke: The Coal Hiding in the Tar Sands:
Quote:
Petcoke can be used just like coal. 15 to 30 percent of a barrel of bitumen can end up as petcoke, depending on the upgrading and refining process used. So a non-trivial proportion of the bitumen extracted results essentially in coal not oil.
It comes from the bitumen in tar sands. Cheap and dirty.
