erneuerbarer

Erneuerbarer is a German adjective meaning renewable. It is derived from erneuerbar and is widely used in contexts related to energy, resources, and sustainability. In everyday language it appears in phrases such as erneuerbare Energie (renewable energy), erneuerbare Ressourcen (renewable resources), and, in a masculine singular form, ein erneuerbarer Energieträger (a renewable energy carrier).

The form of the adjective changes with gender, number and case. For example, masculine singular nominative: erneuerbarer; feminine singular nominative: erneuerbare; plural: erneuerbare Energien (the renewable energies). The underlying stem can also appear in other inflected forms, such as erneuerbaren in the dative plural mit erneuerbaren Energien.

As a noun, Erneuerbare can refer to renewable energies as a category and is capitalized when used in this nominal sense. Common nominal phrases include das Erneuerbare and die Erneuerbaren, with Erneuerbare Energien being the standard term for renewable energies as a group.

In policy and public discourse, the term is central to discussions of the energy transition (Energiewende) in Germany and other German-speaking regions. It denotes technologies, sources, and markets that rely on natural processes to replenish energy supplies, such as wind, solar, hydro, biomass, and geothermal power, with emphasis on sustainability and low carbon emissions.
