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....

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...

We examine the relationship between the choice of steelmaking technology and energy prices in Germany using data beginning 1970. The analysis indicates that technology choice began to cointegrate with comparative energy prices in the early 90s. The short and long-run effects of energy prices are...

Renewable energy policies have been recognized as a cornerstone in the transition toward low-emission energy systems. Media reports are an important variable in the policy-making process, interrelating politicians and the public. To understand the changes in media framing of a pioneering...

This study presents the results of an analysis of user acceptance of PV battery storage systems. A structural equation model is developed based on Davis’ technology acceptance model (TAM). It is expanded by integrating elements of Ajzen’s theory of planned behavior (TPB). The main factors...

Legitimacy is a crucial factor determining the success of technologies in the early stages of development and for maintaining resource flows as well as public and political support across the technology life cycle. In sustainability transitions that unfold over long periods of time, the...

The management of sustainability transitions often includes action to accelerate technological change. Deployment policies are essential measures to increase the adoption of technologies and spur technological development. However, processes of technological development often follow non-linear...

Renewables introduce new weather-induced patterns and risks for market participants active in the energy commodity sector. We present a flexible framework for power spot prices that is capable of incorporating a weather model for the joint distribution of local weather conditions. This not only...

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...

For the global transition of energy systems, the establishment of new energy storage and carrier media to balance the geographical and temporal availability of renewable energy is a necessity. In this context, the interdisciplinary cluster project Clean Circles is investigating the potential of...
