“…For European countries, numerous relevant cases can be found where a broad variety of different methods for analysis is applied. These comprise, in particular, semi-structured interviews with stakeholders, targeted literature reviews, focus groups, choice experiments [35], group discussions with experts from a wide range of sectors (i.e., public and federal authorities, wind park developers, environmental associations), or in-depth analyses of opposition factors of existing energy projects through qualitative semi-structured interviews with opponents and supporters [36][37][38][39]. Additionally, outside of Europe, numerous studies were carried out including consumer analyses based on surveys delivered to a sample of people living close to energy projects, cross-national comparisons of qualitative data, abductive logic-based methodologies with primary and secondary data sources (i.e., documents and archival records, in-depth interviews and direct observation of existing cases) and critical reviews of existing policies, regulations and strategic plans adopted at different territorial levels [40][41][42][43].…”
