What is a common use for propane as an alternative fuel?

Using propane as a fuel in vehicles, particularly in propane autogas systems, is a significant and common application of propane as an alternative fuel. Propane is a clean-burning fuel that can significantly reduce emissions compared to gasoline or diesel. It has a high energy content and is compatible with many existing internal combustion engines when converted properly, which facilitates its use in fleet vehicles, buses, and light-duty vehicles.

The environmental benefits, including lower levels of greenhouse gases and particulates, make propane a favorable option in places where reducing carbon footprints is a priority. In addition to being efficient, propane autogas systems can often be refueled on-site, allowing for greater convenience and cost-effectiveness.

In contrast to the other options, while heating residential homes, supplying energy to commercial kitchens, and running generators are all viable uses of propane, they do not encompass the broader implications and advancements related to propane as a transportation fuel. The innovation and infrastructure established around propane vehicle systems underscore its role as an alternative fuel in the automotive industry.
