While the need and general direction of the energy transition are widely accepted, the implementation has different dynamics throughout the world. Sociotechnical imaginaries concept, bridging the science, policy, and society, seems promising in understanding and explaining the global differences. The present paper analyses 135 abstracts that contain the topic keywords, sociotechnical imaginaries, published in international, peer-reviewed scientific journals during the last 11 years. Further on, the author conducted a qualitative and quantitative analysis of 43 energy-related articles to offer a panoramic overview of sociotechnical imaginaries in energy research out of the more extensive background. The paper aims to present a critical overview of the concept usage in energy studies to identify incoherences and blind spots in concept usage. What is more, this research intents to show the promising direction of using sociotechnical imaginaries. It also proposes new operationalisation and theoretical frame as well as potentially contributes to policymaking.

Numerous case studies show that citizens engage in various ways in renewable and low carbon energy projects, thereby contributing to the sustainable energy transition. To date, however, a systematic and cross-country database on citizen-led initiatives and projects is lacking. By performing a major compilation and reviewing copious data sources from websites to official registries, we provide a Europe-wide inventory with over 10,000 initiatives and 16,000 production units in 29 countries, focusing on the past 20 years. Our data allow cross-country statistical analysis, supporting the elicitation of empirical insights capable of extending beyond the perspective of single case studies. Our data also align with ongoing efforts to implement two EU Directives that aim at strengthening the active role of citizens in the energy transition. While the focus of our data collection is on Europe, the data and methodology can contribute to the global analysis of citizen-led energy action.

While recruitment is an essential aspect of any research project, its challenges are rarely acknowledged. We intend to address this gap by discussing the challenges to the participation of vaccine-hesitant parents defined here as a hard-to-reach, hidden and vulnerable population drawing on extensive empirical qualitative evidence from seven European countries. The difficulties in reaching vaccine-hesitant parents were very much related to issues concerning trust, as there appears to be a growing distrust in experts, which is extended to the work developed by researchers and their funding bodies. These difficulties have been accentuated by the public debate around COVID-19 vaccination, as it seems to have increased parents’ hesitancy to participate. Findings from recruiting 167 vaccine-hesitant parents in seven European countries suggest that reflexive and sensible recruitment approaches should be developed.
