njbill, I've been thinking about this too. Very hard to account for all the variables, but there's one huge environmental/ CO2 cost with fuel oil that gets overlooked. I don''t think you've included it in your analysis, and my bet is that it dwarfs the transportation costs you are considering. I am referring to the electricity demand in petroleum refining
, which is massive. In 2005, US refineries consumed 48.9 Billion KWh, and even in California the biggest industrial consumer of electricity is refining oil.
One of the reasons the environmental implications of this get overlooked is because the great majority of refinery electricity consumed is generated at the refinery from burning petroleum and its products, with only a minority purchased from the grid. No one "sees" how massive the use is because it's (nearly) all internal to the refinery. Yet, such generation via combustion exacts an environmental cost via emissions that I've NEVER seen included in an analysis of environmental consequences of combustion of petroleum products.
In addition to refining electricity consumption, getting it out of the ground in the first place is also energy intensive--one estimate (see below) is that 14 kW are required per barrel of oil, adding $2-3 to the price per barrel. I have no idea whether any anthracite miner has ever done it but it would be easy to do: figure out total energy costs/energy usage per month divided by total tons produced per month. This might allow some (very primitive) comparison of coal vs oil extraction costs.
