Public engagement is considered a crucial process in the transition towards sustainable energy systems. However, less space has been devoted to understand how policy makers and stakeholders view citizens and their relationship with energy issues. Nonetheless, together with technological advancements, policies and political debates on energy affect public engagement as well as individual practices. This article aims at tackling this issue by exploring how policy makers and stakeholders have socially constructed sustainable energy in Italian parliamentary debates and consultations during recent years (2009–2012). Results show that societal discourses on sustainable energy are oriented in a manner that precludes public engagement. The political debate is characterised by argumentative ‘short-circuits’ that constrain individual and community actions to the acceptance or the refusal of top-down decisions and that leave little room for community empowerment and bottom-up innovation.
