Many governments worldwide have initiated energy-management programs, such as Energy Star, an international standard for energy-efficient electronic equipment that was created by the United States Environmental Protection Agency in 1992 and has now been adopted by several other
countries.
Energy Star reduces the amount of energy consumed by a product by automatically switching it into sleep mode when not in use or reducing the amount of power used by a product when in standby mode.
Surprisingly, standby leaking, the electricity consumed by appliances when they are switched off, can represent as much as 12 percent of a typical household’s electricity consumption. In Australia, standby power is a primary factor for the country’s increased greenhouse gas emissions more than 5 megatons
(CO2 equivalent) annually.
