Also, various retailers offer plug adapters or power strips that only use power for a pre-set time (like three or six hours) After the pre-determined time ends, these gadgets stop eating electricity.
[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.
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).
This can be avoided by unplugging the appliance or using a power strip and using the switch on the power strip to cut all power to the appliance." [3] Standby power used by older devices can be as high as 10–15 W per device, [4] while a modern HD LCD television may use less than 1 W in standby mode. Some appliances use no energy when turned off.
If you're like the typical American, you've probably got about 40 household appliances that you routinely leave plugged in – even when these devices aren't actively being used. But did you ...
The use of AC eliminated the need for spinning DC voltage-conversion motor–generators that require regular maintenance and monitoring. Since, for a given power level, the dimensions of a transformer are roughly inversely proportional to frequency, a system with many transformers would be more economical at a higher frequency.
The domestic application attached to home appliance is tied to the definition of appliance as "an instrument or device designed for a particular use or function". [3] Collins English Dictionary defines "home appliance" as: "devices or machines, usually electrical, that are in your home and which you use to do jobs such as cleaning or cooking". [4]
