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...

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...

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...

Geothermal plants have been increasingly constructed in recent years to exploit the high geothermal energy potential in Germany in district heating networks at the municipal level. In order to use this potential economically, municipal planners need instruments for designing the district heating...

This paper presents a stochastic bottom-up model to assess electric vehicles' (EV) impact on load profiles at different parking locations as well as their load management potential assuming different charging strategies. The central innovation lies in the consideration of socio-economic,...

In Europe, the ongoing renewable expansion and delays in the planned grid extension have intensified the discussion about an adequate electricity market design. Against this background, we jointly apply an agent-based electricity market model and an optimal power flow model to investigate the...

An increasing number of municipalities are striving for energy autonomy. This study determines in which municipalities and at what additional cost energy autonomy is feasible for a case study of Germany. An existing municipal energy system optimization model is extended to include the personal...
