Of the three fossil fuels (coal, oil and natural gas), gas releases least carbon dioxide (CO2), so if fossil fuel has to be used, gas is the best.
Gas is also cleaner burning, and easier to "transport" than coal or oil. Gas can be delivered in canisters or through a pipeline from the street. Cleaning and tuning of burners and furnaces is easier as well, plus there is no objectionable smells from normal use. Oil and coal both produce soot and ash, and require a regular service delivery, and more frequent maintenance.
