We don't burn pure C to make CO2 though. We burn hydrocarbons. I am not sure what the effects of the longer carbon chain is. But I feel certain the other extra parts of hydrocarbons leave more energy on the table.

The output might be quite low. But I doubt it would be negative.

Coal is pure carbon more or less. You are right that the math is a bit different for gas and oil.
