“…The desire to generate energy in an independent, self-determinant, and self-sufficient way appears to be a crucial factor in achieving acceptance and commitment. Autarky has been conceptually linked to a variety of psychological constructs such as individuals pursuit of independence (Jager, 2006;Leenheer et al, 2011;Müller et al, 2011;Schmidt et al, 2012;Valkering et al, 2014;Römer et al, 2015;Engelken et al, 2016), autonomy (Fischer, 2004;Späth and Rohracher, 2010;Rae and Bradley, 2012), self-sufficiency (Fischer, 2004;Späth and Rohracher, 2010;Leenheer et al, 2011;Müller et al, 2011;Rae and Bradley, 2012;Schmidt et al, 2012;Römer et al, 2015;Brosig and Waffenschmidt, 2016;Engelken et al, 2016), security of supply (Rae and Bradley, 2012;Römer et al, 2015), and power of control (Fischer, 2004;Valkering et al, 2014). Römer et al (2015) revealed that the affinity toward autarky and the customers' concern about the security of supply are strong factors influencing the intention to purchase small-scale electricity storage systems.…”
