Stand-by mode

Stand-by mode

Stand by
Have you ever considered how many hours per year your electrical devices are in stand-by mode?
Doing a quick calculation, if we have computer equipment on (computer, monitor, printer and speakers) for 8 hours a day, the total number of hours per year would be 2,920 hours. Assuming that the rest of the time the equipment remains in stand-by, the total number of hours in stand-by mode would be 5,840.
Translated to consumption, this is equivalent to 81.76 kWh per year. Taking an average electricity price of 14 cents/kWh, the extra cost of having equipment in stand-by mode would be 11.45 Euros per year. This cost, multiplied for all of the computer equipment in the office, can mean a great deal of money at the end of the year for the business.
According to the Institute for Energy Diversification and Savings (IDAE, in its Spanish acronym) we could save up to 10% of our total consumption just by completely turning off equipment. It's likely that we forget to carry out this simple action on a daily basis, and more so considering that stand-by mode has been invented precisely so that it is not necessary to manually shut off equipment. That's why on the market there are special power strips, called anti-stand by power strips.
Equipment is connected to these anti-stand by power strips, instead of being plugged in directly to the current. Their function is to measure the power current when devices are in "on" mode and detect the decrease when the equipment goes into stand-by mode. At this time, the power strip will cut the current, obtaining savings in the energy consumption caused by stand-by mode.
But the functions of the power strip are not limited to detecting low stand-by consumption and cutting the current; when the power strip detects a new capacity demand (because we've returned to our desk following a meeting, for example) it will automatically allow for the passage of energy.
In reality, conventional power strips also achieve this effect, but manual action is necessary, something we don't always remember to do.
Anti-stand by power strips include, on one hand, a main outlet or master, and on the other hand, secondary outlets, or slaves. The way they work is very simple.
The equipment that controls shutting off (in this case the computers) is connected to the principal or master outlet, and the rest of the periphery devices to be automatically turned off (monitor, printer and speakers) are plugged into the secondary outlets. It is important to remember that the stand-by consumption of the equipment connected to the master outlet will not be eliminated
The price of an anti-stand by power strip is between 10 and 20 Euros. It is thus a relatively small investment that will be defrayed in a maximum of 2 year. It's about taking small steps to save energy and, why not? save on your electricity bill in the process.
