Fuel vs. Gas: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 10, 2024
Fuel is a broad term for any substance used for energy production, while gas specifically refers to a state of matter used as a fuel type.
Key Differences
Fuel encompasses a variety of substances, including solids, liquids, and gases, used for energy. Gas, however, specifically refers to the gaseous state of a substance used as a fuel, such as natural gas or gasoline vapor.
Fuels can be renewable or non-renewable, including biomass, coal, and oil, while gas often refers to substances like propane, butane, or natural gas, which are typically hydrocarbons.
Fuels are used in various applications, from powering vehicles to heating homes. In contrast, gas is used specifically in contexts requiring gaseous fuel, like gas stoves or gas-powered engines.
The term "fuel" has a broader scope, applicable in any context where energy is needed. Gas, in its technical sense, is limited to the gaseous substances used for similar purposes.
All gases used for energy can be considered fuels, but not all fuels are gases. The term "gas" can also colloquially refer to gasoline, a liquid fuel.
