🤔 When to use 'Brennstoff'?
The term Brennstoff is generally used for materials that serve to generate heat or energy through combustion.
- Heating: Holz (wood), Kohle (coal), Heizöl (heating oil), Gas, Pellets as Heiz-Brennstoff (heating fuel).
- Transport: Benzin (gasoline/petrol), Diesel, Kerosin (kerosene) are often more specifically called Kraftstoff or Treibstoff (fuel for engines), but chemically they are also fuels (Brennstoffe). The term Brennstoff is more general here.
- Industry: Kohle, Gas or Biomasse (biomass) for generating process heat.
- Energy production: Kohle, Gas, Müll (waste) or Biomasse in power plants.
A distinction is often made between fossile Brennstoffe (fossil fuels: coal, petroleum, natural gas) and erneuerbare or regenerative Brennstoffe (renewable fuels: wood, biogas, hydrogen).
Compared to 'Kraftstoff' or 'Treibstoff', which are mostly used for engines, 'Brennstoff' is the overarching term for all combustible materials used for energy generation.
