Four user types were discovered based on their goal, attitude, and behavior of electricity usage. By understanding the needs of different user types, we can take advantage of knowing users' needs to try to change their attitudes or to increase their energy-saving intentions. © 2015 IEEE.[SDGs]SDG7Energy conservation; Electricity saving; Electricity usage; Quantitative research; Theory of Planned Behavior; User experience; User type; Behavioral researchconference paper10.1109/IEEM.2015.73857082-s2.0-84962023278
