“…Furthermore, our results demonstrate quantitatively that it is crucial for municipalities to focus first on strengthen local knowledge about RES [KNOW] to improve their performance in RES development (Hypothesis H3). Prior qualitative research already suggested this argument (Cooke, 2013;Jacobsson and Bergek, 2004;Smit et al, 2007;Späth and Rohracher, 2012). Municipalities can generate this specific knowledge by developing policy instruments with focus on renewable energy R&D (Hildén, 2011;Paraskevopoulou, 2012), R&D subsidies (Cantner et al, 2016;Noailly and Smeets, 2015), scientific education in public research institutes and universities (Mowery et al, 2010;Paraskevopoulou, 2012) or municipally-owned companies for the development of renewable energy projects (Gustafsson et al, 2015;Howells, 2005).…”
