Liquefied petroleum gases (LPG) are a group of flammable hydrocarbon gases, primarily composed of propane and butane. These gases are produced during the refining of crude oil and the extraction of natural gas. When cooled or pressurized, LPG turns into a liquid, making it easier to store and transport. It is commonly used for heating, cooking, and fueling vehicles. LPG is popular in many households and industries due to its efficiency and versatility. It burns cleanly, producing fewer emissions compared to other fossil fuels, which makes it a more environmentally friendly option. Many people rely on LPG for their daily energy needs, especially in areas without natural gas pipelines.
