Although many countries have formulated national goals and policies for this, it is often on a local level and typically in a municipal context that these policies are implemented. In Denmark there are 1.1 million single family houses, representing 44% of all existing dwellings in the country. In this regard, this area is considered to have a huge energy saving potential. A growing number of municipalities have ambitions on reducing energy consumption in these buildings, and several municipalities have established initiatives for this. The paper presents the findings from a survey-based project on local initiatives to encourage Danish house-owners to save energy through energy renovation. The paper outlines actors, governance incentives and experiences related to local renovation-based policies. Based on a literature review on international research regarding home-owners motivations for energy retrofitting, the paper discusses how the municipal initiatives can promote energy renovation of detached housing. Methodologically, the research is based on interviews with municipalities and energy suppliers, whom are considered as some of the major actors to provide energy renovation among private house owners.

In ELL1 18 participants were involved, and in ELL2 20 participants were involved. In ELL1, participants mainly lived in detached, privately owned houses, where as participants in ELL2 primarily lived in privately owned terraced hoses. The buildings in ELL1 are older than the buildings in ELL2, and the houses in ELL2 are slightly smaller than the houses in ELL1. There is a mix of household sizes and compositions in each ELL, where the average age of participants in ELL1 is slightly older than the average age of ELL2 participants. ELL1 can be considered a community of place, whereas ELL2 can be considered a community of interest, as ELL2 participants consider themselves to community-builders and to be slightly greener than the average population. This is, however, not necessarily so, as this report will also demonstrate.

This calls for new solutions at all levels of the electricity system. Households are assigned a key role in these changes by system developers, researchers and policy makers, e.g. by realising electricity savings or providing a more "flexible" electricity consumption (also called "load management") in order to optimise the electricity system and balance consum ption with fluctuating electricity generation from e.g. wind power. Thus, development of the so-called "smart grid" is an example of how the changes of a large technological system are affecting all elements of the system. On the basis of a comparative study of Norway, Spain and Denmark, this paper analyses differences and similarities between these countries in relation to the current electricity system, energy policy plans, smart grid research and demonstration activities. The aim of this is to explore how countryspecific factors influence the conceptualisation of households' role in the future smart grid. The analysis focuses on how, for example, differences in national plans for future changes on the electricity production side (like integrating more wind power, hydropower etc.) influence smart grid strategies and understandings of the households' role in the future electricity system. Furthermore, the paper discusses the main challenges and limitations of the present approach to the integration of households in a future smart grid; particularly the importance of understanding the interaction between smart grid technologies and everyday practices. This part draws on practice theory.

In recent years, interest has arisen in the concept of Mobility-as-a-Service (MaaS) as one possible path towards sustainable mobility futures. MaaS builds on the idea of a shift from private car ownership to a seamless and integrated system providing access to multimodal mobility options including public transport and shared mobility services like car and bike sharing. Currently, only few examples of MaaS schemes exist and knowledge of user experiences is limited. The aim of this paper is to contribute to a better understanding of how shared mobilities, like in MaaS, fit with the everyday life of citizens. Methodologically, the paper draws on insights from qualitative interviews with families using a car sharing scheme in Copenhagen. The interviews are informed by a practice theoretical approach to study the potential of inte...

Infrastructure refers to the physical environment, such as roads, buildings, means of mobility, etc., that are not under individual control. The element of near materiality refers to the (material) environment and technologies that are close to the individual user and that are under individual control, such as using the Rejseplanen app on one’s smartphone or a privately owned car or bike.
