Abstract
Denmark uses around 35 TWh of electricity per year, with residential dwellings accounting for around 10 TWh of this figure. Standby consumption comprises around 12% of power used in homes. If every Danish home installed AutoPowerOff plug banks, savings exceeding 500 GWh per year would be possible, equivalent to 5% of household electricity consumption, or 1.5% of the total in Denmark.
This paper describes the estimated standby consumption in Danish homes in 2006, and possible energy savings through the use of AutoPowerOff plug banks. The estimates were subsequently used as background information for a 2007-2008 campaign to promote the wider use of these devices in Denmark.
In order to increase the sale of AutoPowerOff plug banks by 1 million units, it was agreed that retail chains selling consumer electronics would include an AutoPowerOff when selling a TV or PC. A nationwide TV advertising campaign was launched featuring the names of participating retailers.
Sales of AutoPowerOff plug banks in the first 7 months of 2008 passed the 515,000 mark, with over 1 million units now installed in 2.5 million Danish households. Annual savings are estimated to be over 80 GWh, equivalent to 40,000 tons of CO 2 . This equates to potential savings on an EU-wide basis of more than 7 TWh, or 3.6 million tons of CO 2 in Denmark.
