Liquefied Petroleum Gas (LPG) is a clean-burning fossil fuel made up primarily of propane, butane, or a mix of these two gases. It is called 'liquefied' because it is stored and transported in a liquid state under pressure in cylinders or tanks. LPG is known for its versatility and can be used for heating, cooking, and as fuel for certain vehicles, among other applications.

LPG is produced during the extraction of natural gas and crude oil from the ground, as well as during the refining process of crude oil. It is separated from the unprocessed gas using refrigeration and from crude oil during the refining process. Once extracted, LPG is stored in pressurized containers to keep it in liquid form until it's ready to be used.

LPG is widely used in residential settings for heating and cooking because it is efficient and clean-burning. It's also used in agriculture, for crop and produce drying, in industry, for powering machinery, and in automotive applications as an alternative fuel for vehicles. Additionally, LPG is used in commercial enterprises, including restaurants and hotels, for heating and cooking.

The benefits of using LPG include its high energy efficiency, its cleaner-burning nature compared to coal and petrol, and its portability, which makes it accessible even in remote areas. LPG emits fewer greenhouse gases and pollutants like sulfur dioxide and particulate matter, making it an environmentally friendlier choice. It also provides a flexible and convenient energy source that can be used across a wide range of applications.

While LPG is relatively safe, it does require careful handling and storage to prevent accidents, as it is highly flammable. Safety concerns include the risk of leaks, which can lead to fires or explosions if the gas is ignited. To mitigate these risks, LPG cylinders and appliances should be regularly checked for leaks, and installations should only be performed by qualified professionals. Adequate ventilation is also crucial in areas where LPG is used to avoid inhalation hazards.
