Compare LPG and wood as fuels.
Wood
-It is considered a traditional fuel used for both domestic and industrial purposes.
-Wood produces a lot of smoke which pollutes the atmosphere and causes respiratory diseases.
-The usage of wood to a large extent causes deforestation.
-The calorific value of wood ranges between 17000 to 22000 kJ/kg
-However, wood may be used as a furnace, stove, or fireplace indoors while it is used for a campfire, furnace outdoors.
-It can’t be transported easily like LPG fuels.
LPG
-The usage of LPG (Liquefied petroleum gas) has replaced wood.
-It doesn’t release smoke and other pollutants.
-It is a cleaner fuel.
-The fuel efficiency of LPG is more than that of wood.
-The calorific value of LPG is 55000 kJ/kg.
-It can be easily transported in cylinders as it is stored in a liquid state.
-Hence, LPG is the most preferred choice.
