Energy Labels and Heuristic Decision-Making:The Role of Cognition and Energy Literacy
To overcome the inefficiency in household energy use, energy labels with a grade-like categorical efficiency rating-scale are widely used across the globe. However, presenting energy efficiency information in categories has been found to induce heuristic rather than rational decision-making, known as the "class valuation effect": consumers value the classes, while being inattentive to the actual energy use of the respective appliance. Although replacing the categorical by a continuous scale could eradicate this effect, it has not been formally examined to what extent a continuous scale promotes more rational decision-making. This study investigates whether visualising energy efficiency using a continuous-scale instead of a categorical-scale energy label increases consumers’ awareness of the energy performance of appliances. We experimentally examine this question in an online survey with randomised decision tasks conducted in China and the Netherlands, two countries using energy labels with categorical rating-scale whose populations differ in cognitive style and energy literacy (energy-related knowledge, attitudes, and behaviours). We find that continuous-scale labels are overall more effective in promoting rational decision-making. For Dutch respondents the effectiveness depends on their holistic cognitive tendency and the type of comparison they are faced with, whereas the Chinese sample is not sensitive to these moderators. Moreover, we find that the different aspects of energy literacy have opposing influence on rational choices: possessing knowledge related to daily-life energy use increases the likelihood of rational decisions, while energy-saving attitudes and behaviours encourage individuals to opt for more energy-efficient appliances even when it is not economically optimal. Based on the results, we suggest to represent energy efficiency on continuous scales as an auxiliary visual information to support purchase decisions. In energy education and information programmes, emphasis should be put on energy knowledge that directly links to daily life, which is well translated into consumers’ conscious decisions.
