biogas
A combustible gas mixture that is produced through the fermentation of organic material such as liquid manure, organic waste, or energy crops in the absence of air. It is used to generate electricity and heat.
Viele Landwirte betreiben eine Biogasanlage, um aus ihren Abfällen Energie zu gewinnen.
Many farmers operate a biogas plant to generate energy from their waste.
The word is made up of 'Bio-' and 'Gas' (gas). The prefix 'Bio-' indicates that the gas is obtained from organic, that is, 'living,' material such as plants or waste.
Biogas ist eine Form der erneuerbaren Energie.
Biogas is a form of renewable energy.
Common verbs in connection with 'Biogas' (biogas) are 'erzeugen' (to generate), 'produzieren' (to produce), or 'gewinnen' (to obtain). It is also often used for generating electricity or heat.
Der Landwirt erzeugt mit seiner Anlage genug Biogas, um das ganze Dorf mit Wärme zu versorgen.
The farmer generates enough biogas with his plant to supply the whole village with heat.
A very common and important word in this context is 'die Biogasanlage' (biogas plant). This is the technical facility in which the biogas is produced.
Die neue Biogasanlage wurde letzte Woche offiziell in Betrieb genommen.
The new biogas plant was officially put into operation last week.
natural gas
'das Erdgas' and 'das Biogas' are both combustible gas mixtures and can be used to generate heat or electricity. The difference is mainly in their origin. Natural gas comes from underground deposits and is a fossil raw material. Biogas is produced from organic material such as liquid manure, organic waste, or plant residues. The words can be confused because both serve as energy gases. When it is gas from the earth, you say 'Erdgas'; when it is produced from fermented organic material, you say 'Biogas'.
Auf dem Bauernhof wird aus Bioabfällen Biogas gewonnen.
On the farm, biogas is produced from organic waste.
