This paper empirically analyzes the relationship between refrigerator’s actual electricity consumption, its energy consumption efficiency (kWh/year), usage mode, and other various attributions using household-level data whose sample size is 232 households. Our result shows that refrigerator’s actual electricity consumption may decrease from 0.52% to 0.56% in response to a one percent improvement in its energy performance. According to this result, there is one possibility that an increase in refrigerator’s energy-efficiency can cut its actual electricity consumption by 26% in a household. Moreover, our estimation results suggest that the effort to save energy at household-level can play an important role in decreasing the actual consumption, and, therefore, it is significant that consumers obtain an adequate knowledge of further energy-saving.
