Enhancing people's energy behavior is an important research topic. We aim to support people by recommending specific energy-saving actions when they have the opportunity to save energy. To persuade people to execute the actions we incorporate findings of models related to behavior change into the system's decision making process. In this paper, we consider how the idea of Energy Cultures can be integrated into a recommender system and present results of an online survey that investigates the effect of users' Energy Culture on their preferences for energysaving actions.
