Please check my calculations and correct me if I'm wrong.5,800,000 BTU's in one 42 gallon barrel of oil. Cost of a barrel of oil is about $110/barrel. Therefore, the cost of 1,000,000 BTU's of oil would be $18.97.1,030,000 BTU's in one Mcf of natural gas. Approximate cost of 1 Mcf of natural gas is about$2.50. Therefore, the cost of 1,000,000 BTU's of natural gas would be $2.43.30,600,000 is the approximate BTU's in a ton of coal. I'm guessing that a ton of bituminous coal sells for about $20/ton. This would result in the cost of 1,000,000 BTU's of coal being $0.65.If my numbers are anywhere near correct, it would appear that natural gas would be about 8% the cost of oil on a BTU basis, and that the cost of coal would be about 3% the cost of oil on a BTU basis. Are these calculations anywhere near correct?
Natural gas at $2.30 (price today) is cheaper (slightly) than coal. Your crude oil number is correct. Just US numbers. Natural gas in Europe and Asia is about $17 (equivalent).
I don't know where you got your numbers from, but up here in northeast PA a ton of rice anthracite the kind that burns in home heating stokers goes for well over $100.00 per ton delivered.
Can you drive your car to work on coal BTUs? Most people can't afford the 50K electric car yet.
All I want to know is the relative cost of coal, oil, and natural gas. I know there are differences in how they can be used. But cost is a big factor for some usage purposes. Please just check my math.
