In this study we examine some specific opportunities to reduce standby losses in electronic appliances. A review of power consumption levels for the major components responsible for standby functions indicates that nearly all standby functions can be performed with a total appliance standby power consumption of one watt or less. We therefore propose that standby losses be limited to one watt per appliance, a significant reduction from current levels for many appliances. This target could be achieved with little or no extra cost to manufacturers and could save over $2 billion in annual U.S. energy costs. Globally, a one-watt plan would lead to a significant reduction in carbon emissions.
