Der Energieanbieter RABOT Charge macht es f&uuml;r jeden m&ouml;glich, unkompliziert aktiver Teil der Energiewende zu werden. RABOT Charge denkt Energie neu und bietet f&uuml;r Kund*innen einen dynamischen Stromtarif f&uuml;r Haushalt und Elektroauto mit 100% &Ouml;kostrom an. Das hei&szlig;t, im Gegensatz zu anderen Stromanbietern, kauft Rabot Charge Strom kurzfristig &uuml;ber den Day-Ahead und Intraday-Markt ein, nutzt somit die st&uuml;ndlichen Preisschwankungen an der Stromb&ouml;rse und gibt den Einkaufspreis direkt an Kund*innen weiter. So k&ouml;nnen zum Beispiel E-Autos automatisiert dann geladen werden, wenn der B&ouml;rsenstrompreis 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 k&ouml;nnen Verbraucher*innen in Echtzeit in der RABOT Charge App nachverfolgen und steuern. Ziel ist es, intelligenten und nachhaltigen Stromkonsum f&uuml;r jeden zug&auml;nglich zu machen und den Ausbau erneuerbarer Energien voranzutreiben, um den Klimawandel zu bek&auml;mpfen.
