Electricity consumption feedback applications are considered one of the critical technologies in alleviating the increasing trends of energy consumption and greenhouse gases emissions. Feedback applications are used to motivate electricity users to conserve energy in their households. In this paper, we have relied on an integrative theoretical framework and literature review to propose a comprehensive taxonomy for salient design elements of electricity consumption feedback applications. Using a survey method, we collected data to evaluate the preference and relative importance of the design elements. We found that there is a preferred set of design elements for the feedback applications. Our results could serve as a basis to evaluate the design of existing electricity consumption feedback applications, and help in studying the influence of design elements on beliefs and behaviors related to individuals’ electricity conservation.
