Gas
The difference between propane, or liquid petroleum gas (LPG), and natural gas comes down to their portability, compression, energy efficiency, and cost. However, there is generally no difference when it comes to performance in appliances for heating, cooking, or drying. The mixture of natural gas is comprised of propane, along with other gases like methane, butane, ethane, and pentane.
