Energy conservation is a key challenge for a sustainable lifestyle. However, it is often ignored because of a lack of knowledge and inability to predict the lifetime of electric or electronic equipment. Energy conservation is the most cost-effective strategy for coping with energy shortage. This study proposes the implementation of e-Life devices to solve this problem and promote public awareness. Electricity-intensive products have their own power specifications and lifespans; over time, the amount of power they use is greater than expected because of the effects of aging. The e-Life algorithm used in an Internet of Things (IoT)-enabled electronic device is integrated into any electrical load to monitor power usage and understand the product replacement time. It is proposed to be aware of the excessive power consumption of all-electric or electronic equipment.
