Der Energieanbieter Rabot Energy macht es für jeden möglich, unkompliziert aktiver Teil der Energiewende zu werden. Rabot Energy denkt Energie neu und bietet für Kund*innen einen dynamischen Stromtarif für Haushalt und Elektroauto mit 100% Ökostrom an. Das heißt, im Gegensatz zu anderen Stromanbietern, kauft Rabot Energy Strom kurzfristig über den Day-Ahead und Intraday-Markt ein, nutzt somit die stündlichen Preisschwankungen an der Strombörse und gibt den Einkaufspreis direkt an Kund*innen weiter. So können zum Beispiel E-Autos automatisiert dann geladen werden, wenn der Börsenstrompreis in einem festgelegten Ladezeitfenster besonders gering ist. Da bei viel Wind und Sonne die Preise niedrig sind, wird so nicht nur der Geldbeutel geschont, sondern auch die Umwelt. Den Energieverbrauch sowie das smarte und automatisierte Energiemanagement können Verbraucher*innen in Echtzeit in der Rabot Energy App nachverfolgen und steuern. Ziel ist es, intelligenten und nachhaltigen Stromkonsum für jeden zugänglich zu machen und den Ausbau erneuerbarer Energien voranzutreiben, um den Klimawandel zu bekämpfen.
