energy carrier
A substance, object, or physical system that stores energy and can release it again when needed. A distinction is made between fossil energy carriers (e.g., coal, petroleum), nuclear energy carriers (e.g., uranium), and renewable energy carriers (e.g., sun, wind, biomass).
Wasserstoff wird als sauberer Energieträger der Zukunft gehandelt.
Hydrogen is being touted as a clean energy carrier of the future.
The word is made up of 'Energie' (energy) and 'Träger' (carrier). A 'Träger' is someone or something that carries something. An 'Energieträger' (energy carrier) is therefore literally something that carries or stores energy within itself.
Kohle ist ein fossiler Energieträger.
Coal is a fossil energy carrier.
'Energieträger' (energy carrier) is often combined with adjectives that describe its origin. The most common are 'fossile Energieträger' (fossil energy carriers), 'erneuerbare Energieträger' (renewable energy carriers), and 'konventionelle Energieträger' (conventional energy carriers).
Die Bundesregierung fördert die Nutzung erneuerbarer Energieträger.
The federal government promotes the use of renewable energy carriers.
'Energieträger' (energy carrier) is often used with verbs such as 'nutzen' (to use), 'speichern' (to store), or in the construction 'als Energieträger dienen' (to serve as an energy carrier).
Wind und Sonne dienen als saubere Energieträger.
Wind and sun serve as clean energy carriers.
fuel
'der Treibstoff' and 'der Energieträger' both have to do with stored energy. 'Treibstoff' is a substance that provides propulsion in motors or engines, for example gasoline, diesel, or kerosene. 'Energieträger' (energy carrier) is much more general and is often used in contexts involving energy, the environment, or technology. It can also include coal, petroleum, uranium, the sun, wind, or biomass. The words can be confused because many fuels are also energy carriers. But not every energy carrier is a fuel. When it is about an engine, 'Treibstoff' fits. When it is about energy sources in general, 'Energieträger' fits.
Im Unterricht vergleichen wir erneuerbare Energieträger wie Sonne und Wind.
In class, we compare renewable energy carriers such as the sun and wind.
Brauchen wir für den Generator noch Treibstoff?
Do we still need fuel for the generator?
