Fuel
Fuel is a substance that provides energy when burned or processed to power engines, machines, or other systems. It can be liquid, such as gasoline or diesel, or gaseous, like natural gas. When combusted, fuel releases stored energy, converting it into heat and movement. This process drives cars, generates electricity, or heats buildings. Fuels are derived from natural resources like oil, coal, or gases, and their use is essential for transportation, industry, and daily life. Understanding fuel is key to managing energy use effectively and exploring sustainable alternatives.
