Abstract
This paper investigates the factors that affect the use/purchase of energy-saving electrical appliances in Sri Lankan households. A theoretical model was developed utilizing the technology acceptance model and incorporating perceived affordability. Twelve hypotheses were tested based on data obtained from a survey conducted in the Sri Lankan Kalutara district for a sample of 384 residences. Statistical analysis was done using IBM SPSS 26 and Smart PLS 3 software. The results show that perceived usefulness and perceived ease of use have significant relationships with attitude and behavioral intention of purchasing energy-saving appliances. The moderating effects of perceived behavioral control to the relationships between perceived ease of use and perceived usefulness are not significant. Also, there was no significant moderating effects of affordability on the relationship between behavioral intention and attitude. The main conclusions were that perceived ease of use, perceived usefulness, attitude, perceived behavioral control, subjective norms, and perceived affordability significantly affected the behavioral intention to purchase energy-saving household appliances. Although Sri Lanka has begun spreading awareness on the use of energy-saving appliances, limited number of studies have reported on this topic. The results of the study suggest that the Ministry of Energy must apply a solid comprehensive awareness program in Sri Lanka, addressing environmental aspects, benefits for the consumers with regards to their health, safety, and interest as well as promoting Energy Star Labels. Additionally, instilling policies involving government loan schemes, low interest rates, and subsidies could serve as motivators for consumers to adopt energy -saving appliances.
