Analysis of Household Energy Consumption of Lighting and Electric Appliances and Predictions for 2020

increase in household energy consumption has been more apparent than such increases in the industrial and transportation sectors. The sources of household energy consumption can be classified into heating and cooling, cooking, hot-water supply, and lighting and electric appliances. In particular, energy consumption for lighting and electric appliances has been significantly increasing. In order to consider energy-saving measures in the home, we should trace the tendencies of increasing energy consumption due to lighting and electric appliances in recent years. In this paper, we analyze the current level of energy consumption for lighting and electric appliances and, moreover, attempt to predict the level we can expect in 2020. Consequently, it is estimated that the energy consumption of lighting and electric appliances will decrease by 16% from the 2010 level, mainly due to the energy savings expected for refrigerators and lighting.
