The cover picture: Authors I Acknowledgment With this note of acknowledgment, we want to express our heartfelt gratitude to all individuals and organizations that made this research possible. Without the help and assistance of Durness Development Group and Community Energy Scotland, this study could not have been successfully done. Special thanks go to the directors of Durness Development Group, Neil and Sarah Fuller, for their contribution and support towards our work during the time of the project, and to Nicholas Gubbins from Community Energy Scotland for providing us key information required for this study. The research team is very grateful to our supervisors from the University of Flensburg, Prof. Dr. Bernd Möller, Dipl.-Ing. Wulf Boie and Dipl.-Soz. Dorsi Germann for their academic guidance, support and patience before and during the study. We also recognize and thanks the Deutscher Akademischer Austausch Dienst (DAAD, German Academic Exchange Service), for their financial support which allowed us to do this International Class 2017.
