The Relationship between the Factors Influencing Energy-Saving Behaviors in Households in Urban Vietnam

Research on energy-saving intentions (EI) and behaviors will provide appropriate policies to help raise the awareness of energy saving in households. Therefore, the present study assesses the factors influencing energy-saving intentions and behaviors in urban households. The authors evaluated 1037 samples gathered from homes in the Hanoi metropolitan region of Vietnam by utilizing a questionnaire to survey and household interviews based on the theory of planned behavior (TPB) and multivariate analytic techniques (scale reliability test, factor confirmation analysis). The Partial Least Squares - Structural Equation Modeling (PLS-SEM) model has shown that energy-saving awareness (EA) and situational factors (SF) both have strong influences on energy-saving behaviors (EB). In particular, the situational factor has a stronger impact on energy-saving behavior than the energy-saving awareness factor. As a result, the factor of energy-saving awareness plays an important role in shaping energy-saving intention and orientation of energy-saving behaviors. Moreover, energy-saving intention acts as an intermediary among factors that impact energy-saving behaviors. Consequently, numerous policies have been proposed to help raise the awareness of energy saving for urban households. Households need to adopt a more environment-friendly lifestyle. The results of this study shall be the theoretical base for other research in Vietnam about energy-saving behavior.
