Stand By Power
Does it really account for 10% of usage?
Where do we get this this rule of thumb from. Is this accurate?
I am talking about electricity consumption, not all energy consumption.
So, where did the 10% come from? VERY good question. The 10% figure came from a detailed study of standby power consumption back in 2005.
The principles and appliance usage still stands. A total of 8000 individual appliances from 120 homes were recorded during the survey. Appliances were recorded in all relevant standby modes, such as active standby, passive standby or off mode. The results showed that the average standby consumption for 2005 was found to be 92.2 Watts per household, or some 807 kWh per year. This equates to around 10.7% of residential electricity consumption in 2005.
The above graph shows the Stanby power used by different appliances.
If you feel you want to do something about the amount of wasted electricity (not to mention the cost) then have a look at theEco Switch, a simple an easy way to reduce or eliminate the wastage of standy power.
