Energy-saving behaviors hold substantial potential for curbing residential energy consumption, and this potential is shaped by a multitude of determinants. In this chapter, residential energy-saving behaviors are categorized into three distinct types: investment behaviors, control behaviors, and careful-use behaviors. Subsequently, based on survey data gathered in Changchun, China, we conduct a more in-depth exploration of careful-use behaviors within the theoretical framework of the Theory of Planned Behavior (TPB). Structural equation modeling is employed to analyze careful-use behaviors. This chapter highlights the impact of careful intentions on careful-use behaviors, with these intentions being further influenced by three key driving factors: attitude, subjective norm, and perceived behavior control (PBC). A particularly notable discovery of this chapter is that, when it comes to careful-use behaviors, the subjective norm exerts the most significant influence. This finding represents a stark contrast to previous studies that focused on investment behaviors or other forms of energy-saving behaviors. Correspondingly, policy recommendations for promoting careful-use behaviors from the perspective of subjective norm are put forward. It is proposed that the dissemination of energy-related knowledge and the publicity of energy-related information should be extensively carried out. Additionally, efforts should be made to enhance pro-environmental attitudes through educational means.
