because it is
Coal tends to be cheaper than oil because coal is more abundant and easier to extract from the earth. Additionally, coal production costs are generally lower than oil production costs. Supply and demand also play a role in determining the price difference between coal and oil.
1. its easier to get out of the ground than coal 2. cheaper than coal to transport
Oil generally burns hotter than coal. This is because the carbon content in oil is higher than that in coal, resulting in a more efficient combustion process and higher heat output.
Coal is less expensive than oil and will be more plentiful in years to come
Oil can be extracted much easier than coal because it is a liquid. Once the oil reservoir is tapped, it can be removed relatively easily, whereas coal must be physically removed at every extraction.
Oil generally burns at a similar temperature to gas, but hotter than coal. The burning temperature can also depend on the specific type of oil or gas being used.
Coal and oil
Na2so4
they burn fossil fuels like coal, fuel oil, and oil shale
because crude oil and gas are cleaner to burn
Oil is usually cleaner to mine and transport than coal (unless there's an oil spill!)Oil emits less carbon dioxide pollution than coal when burnt, so it contributes less to global warming than coal does.
