Entropie im Erdsystem: Wie das Klimasystem arbeitet
Bei den Energieumwandlungen der Erde ist die Entropie immer mit dabei. Wie ein Kompass bestimmt sie dabei die Richtung, sie setzt Leistungsgrenzen, die Klima formen und erneuerbare Energien begrenzen. Zusammenfassung Entropie setzt Grenzen, wenn Energie umgewandelt und Arbeit geleistet wird – so wie bei Wärmekraftmaschinen und Kraftwerken.
