One Watt Initiative

The One Watt Initiative (or the proper One-Watt Initiative) is an energy-saving initiative by the International Energy Agency (IEA) to reduce standby power-use by any appliance to not more than one watt in 2010, and 0.5 watts in 2013, which has given rise to regulations in many countries and regions.

Standby power, informally called vampire or phantom power, refers to the electricity consumed by many appliances when they are switched off or in standby mode. The typical standby power per appliance is low (typically from less than 1 to 25 W), but, when multiplied by the billions of appliances in houses and in commercial buildings, standby losses represent a significant fraction of total world electricity use. According to Alan Meier, a staff scientist at the Lawrence Berkeley National Laboratory, standby power before the One Watt Initiative proposals were implemented as regulations accounted for as much as 10% of household power consumption. A study in France found that standby power accounted for 7% of total residential consumption, and other studies put the proportion of consumption due to standby power at 13%.

The IEA estimated in 2007 that standby produced 1% of the world's carbon dioxide (CO₂) emissions. To put the figure into context, total air travel contributes less than 3% of global CO₂ emissions.

Standby power can be reduced by technological means, reducing power used without affecting functionality, and by changing users' operating procedures.

The One Watt Initiative was launched by the IEA in 1999 to ensure through international cooperation that by 2010 all new appliances sold in the world use only one watt in standby mode. This would reduce CO₂ emissions by 50 million tons in the OECD countries alone by 2010; the equivalent to removing 18 million cars from the roads.

In 2001 US President George W. Bush issued Executive Order 13221, which states that every government agency, “when it purchases commercially available, off-the-shelf products that use external standby power devices, or that contain an internal standby power function, shall purchase products that use no more than one watt in their standby power consuming mode.”
