This paper provides new understanding on how intermediary actors support the adoption of renewable electricity technology. While intermediaries complement each other in different phases of the process, there are also gaps and overlaps in the support that they provide. Results indicate that there is a great need of improving the communication among intermediaries and of a higher level of coordination among the tasks performed. Fostering the widespread adoption of renewable energy technologies is one of the most important drivers to limit the irreversible consequences of global warming that the world is facing today. However, the process of adopting such innovations is often complex and challenging. Previous studies have recognized the crucial role of intermediaries in facilitating the adoption process. Yet, little is known about how different intermediaries support the various adoption process phases, which intermediary type does what, and whether there are support gaps or overlaps among them. The authors of this paper contribute to previous research on innovation adoption and innovation intermediaries based upon research on the adoption context of renewable energy technologies in Sweden. They gathered secondary data and semi-structured interviews with nineteen intermediaries who support the adoption process of renewable energy technologies. The finding of this paper has implications on policy design, with regard, to how intermediaries can better perform in a technology diffusion context and to how intermediaries can be coordinated to provide better services during the different phases of the adoption process.
