Development of Energy Consumption Profiles of Common Household Appliances by Analyzing their Energy Consumption

Residential energy consumption constitutes a major share of overall electricity demand, and inefficient use of household appliances, including hidden standby loads, which contributes to higher energy costs, wasted resources, and barriers to sustainable energy management. Addressing this requires accurate insights into how appliances consume energy in real-time, enabling more efficient strategies for household, utilities, and policymakers. This study conducted a comprehensive analysis of residential energy consumption by monitoring the real-time energy usage of common household appliances. The primary goal was to develop detailed energy consumption profiles that could benefit both researchers and distribution companies. To achieve this, the energy consumption data of various household appliances were recorded over a period of one month with a high time resolution of one-second intervals, utilizing smart plugs for wireless energy measurement. A significant focus of the study was to understand the impact of standby power consumption on overall energy use and efficiency. By accurately measuring appliance-level energy consumption, the study was able to create detailed profiles, which were then used to predict the energy use for the following month. The predicted total monthly energy consumption was validated against actual energy bills provided by the state electricity board, demonstrating the reliability and accuracy of the predictions. The collected data from this study offers a valuable database for identifying and understanding energy consumption patterns of household appliances, which is essential for residential energy management research. Further, the findings emphasize the significance of real-time monitoring in crafting effective energy management strategies. Such strategies can lead to more sustainable energy use, benefiting both consumers and energy providers. On a broader scale, this method can support economic development by enhancing energy efficiency and reducing waste. The study underscores the potential of detailed, real-time energy monitoring to improve energy policy and household energy management, paving the way for more informed and sustainable energy practices.
