Demorest has propane and natural gas available for sale. Both of these are sources of fuel, and are used in various appliances as the source of power. These appliances are usually for heating, cooking, or drying. These gases differ in a number of ways, such as energy efficiency, cost, compression, storage, and risk factors. Propane is more expensive than natural gas. Both of these are stored in compressed form- natural gas can be stored in liquefied form as well. Natural gas tanks are heavier because more pressure is needed to compress it. Both of these can pose an explosive risk, so one must be careful about buying well-sealed tanks, as well as properly connected pipelines with no leakages when being used.
