Energy Assessment on Standby Power Consumption of Common Household Electronic Appliances

Abstract

Most Filipinos in this modern generation have household appliances as a form of convenience in their daily lives. The usage of these common household appliances is indeed helpful, and they also play a huge part in the energy consumption of households. These appliances, despite not being used for some time, still consume energy when left unplugged, which is known as standby power consumption. A quantitative-descriptive survey questionnaire was used in the study to identify common household electrical appliances in the households. The power consumption of these appliances was measured and calculated for energy assessment. Using a digital energy logger, the measured power consumption shows that the standby power consumption ranges from 0.1 W to 3 W. These values are relatively small, but they become significant in the monthly or yearly possible energy savings of up to 3.34%. Thus, the study on the energy assessment of standby power consumption can provide insights and opportunities to reduce the residential demand for electricity. Household appliance manufacturers should take the lead in spreading awareness of the energy wasted on standby power through their product labels, encouraging residents to be more conscious of the power consumed by these plugged-in appliances when not in use.
