Der BMBF Wettbewerb „Energieeffiziente Stadt“ gibt fünf Städten in Deutschland die Gelegenheit, ihre jeweiligen Konzepte zur Steigerung der städtischen Energieeffizienz umzusetzen. Zur Beherrschung der Komplexität werden dabei verschiedene Methoden und Modelle eingesetzt. Dieser Beitrag...

Utilization of electric vehicles provides a solution to several challenges in today’s individual mobility. However, ensuring maximum efficient operation of electric vehicles is required in order to overcome their greatest weakness: the limited range. Even though the overall efficiency is...

Despite the vast literature on the energy-efficiency gap, there is a general dearth of investment models which incorporate the consumer's temporal freedom in the investment decision. Focusing on the building sector, we formulate optimal investment in energy efficiency as a problem of wealth...

Climate change mitigation is one of the greatest human challenges. The associated transformation of energy supply and demand to low-carbon energy sources requires not only technical solutions, but also involves consumers and as such, represents a holistic societal process. To date, however, the...

We revisit optimal investment in energy-efficiency, presenting a decision framework built around the agent's wealth and wealth dynamic. An investment rule in the form of a trigger is derived such that the agent invests the first time the energy-carrier price crosses this threshold from below....
