[4] The first appliance labeling rule was established in 1979 and all products were required to carry the label starting in 1980. Energy Star is a similar labeling program, but requires more stringent efficiency standards for an appliance to become qualified, and is not a required program, but rather a voluntary one.
But did you know that even when they're turned off, appliances and electronic gadgets gobble up energy, costing you money? The average U.S. household spends about $1,900 a year on energy costs ...
A typical energy rating label. In Australia and New Zealand, an energy rating label or energy rating is a label affixed to various appliances prior to retail sale, which allows consumers to compare the energy efficiency of product and allows consumers to know how much power a particular model will use to run.
Domestic energy consumption refers to the total energy consumption of a single household. Globally, the amount of energy used per household may vary significantly, depending on factors such as the standard of living of the country, the climate, the age of the occupant of the home, and type of residence.
For refrigerating appliances, such as refrigerators, freezers, wine-storage appliances, and combined appliances, the labelling is specified in terms of an energy efficiency index EEI, which is an indication of the annual power consumption relative to a reference consumption that is based on the storage volume and the type of appliance (refrigerator or freezer).
Energy Star qualified televisions [29] use 30% less energy than average. In November 2008, television specifications were improved to limit on-mode power use, in addition to standby power which is limited by the current specifications. Standby power consumption for televisions must be 3 watts or less. [30]
Home idle load is the continuous residential electric energy consumption as measured by smart meters. [1] [2] [3] It differs from standby power (loads) in that it includes energy consumption by devices that cycle on and off within the hourly period of standard smart meters (such as fridges, aquarium heaters, wine coolers, etc.).
A stand-alone in-home system, under the control of the user, can provide feedback about energy use, without revealing information to others. Drawing links between their behavior and energy consumption may help reduce energy consumption, improve efficiency, flatten peak loads, save money, or balance appliance use with green energy availability.
