Propane consumption by sector
Propane, a liquefied petroleum gas, accounts for around 2% of energy supply in the United States. As you can see from the pie below, it is mostly used for petrochemical and residential purposes. Millions of households use propane as a source of energy: it is efficient and relatively cost-effective, often more so than other sources of energy, like electricity.
Residential propane consumption
Residential propane users find it convenient for outdoor grills, water heating, space heating, refrigeration, clothes-drying and even outdoor lighting. The advantage of propane is that it is stored directly on the property in a large tank so supply is secure and controlled by the homeowner or tenant.
