Emotions may play an important role in how citizens respond to public policies, and energy policies in particular. Yet, little insights exist into causes of those emotions. This study investigates ethical concerns as the basis of emotions. We test whether people perceive an unequal distribution of negative outcomes of a local energy project as more unfair than an equal distribution thereof and, in turn, experience stronger negative emotions (hypothesis 1) and whether these effects depend on whether the project has personal consequences or not (i.e. the self-relevance of the project; hypothesis 2). In an experiment with a 2 (equal vs. unequal distribution) by 2 (self-relevant vs. not self-relevant) design (N = 282), we find support for hypothesis 1, but not 2. Furthermore, we find that perceived total amount of harm, an ethical concern about the total amount of negative outcomes bestowed on all people together, is also (marginally significantly) affected by the unequal distribution and relates to the emotions. We argue that justified ethical concerns are at the root of emotions about renewable energy projects and therefore emotions and their underlying ethical concerns should be considered for socially responsible as well as successful energy policy making.@en

Energy projects aimed at a sustainable energy transition can trigger strong negative emotions and resistance from the public. While practitioners are increasingly realising that they cannot simply ignore public emotions, they struggle with how to deal with people's emotional responses and how to secure public acceptability of sustainable energy projects. We argue that a first critical step in order to adequately address emotional responses to energy projects is to understand where these emotional responses come from. We introduce a value-based approach, which entails that different characteristics of energy projects may violate or support people's core values, which evokes emotions in people. We present a theoretical framework of the relationship between people's values, the (perceived) implications of energy projects for these values, and people's emotional responses to energy projects. We give examples from case studies in the literature to substantiate our reasoning, and we offer directions for future research. Our novel approach provides critical insights for project developers, decision makers, engineers, and scientists who aim to better understand the human dimension of a sustainable energy transition.
