Fuels are substances that can be burned (combusted) to release energy in the form of heat and light. They react with oxygen to produce energy.
Types:
- Solid: coal, wood
- Liquid: petrol, diesel
- Gas: natural gas (methane)
Fuels are classified as fossil (formed from ancient organisms, non-renewable) or renewable (biofuels from plants).
Energy from fuels powers vehicles, heating, electricity generation.
