Decision-Making Strategies for the Choice of Energy-friendly Products

Although energy efficiency of many products has been improving constantly, residential energy consumption is not decreasing as much as desired. Therefore, the goal of the European Union (EU) and many other countries is to promote energy-friendly product choices (i.e., choice of products with low energy consumption). In a purchase situation, consumers are confronted with a wide range of energy-related information that can influence the decision-making process. Understanding how consumers reach a decision based on the information provided and identifying decision-making strategies that are beneficial or destructive in terms of energy friendliness is crucial for the improvement of existing energy-policy measures and, consequently, for the successful achievement of target energy saving goals. This paper provides insights from an exploratory eye-tracking study (N?=?59) investigating consumers’ decision-making process. Participants were required to identify the most energy-friendly television (i.e., the television with lowest energy consumption). Cluster analysis revealed three consumer segments with different decision-making strategies: the energy-directed lexicographic, unsystematic lexicographic, and unsystematic exhaustive strategies. The energy-directed lexicographic strategy resulted in 60% optimal choices in terms of energy friendliness, unsystematic lexicographic in 33%, and unsystematic exhaustive in 38%. No decision-making strategy resulted in 100% optimal choices in terms of energy friendliness. Findings emphasize that lexicographic strategies can successfully identify energy-friendly products when the correct information (i.e., actual energy consumption) is used. However, a lexicographic strategy can be very misleading and result in non-optimal choices in terms of energy friendliness when it is based on ambiguous information (i.e., energy efficiency information) that does not enable a conclusive decision. Further, this paper discusses implications for policy-makers and marketers for the promotion of energy-friendly consumer behaviour.
