Η κλιματική αλλαγή μπορεί μερικές φορές να είναι ένα αμφιλεγόμενο theme, but even skeptics would have to admit that there is no reason to waste energy unnecessarily.
Whether we work in the office or at home, many of us tend to turn on sleep on laptops and other devices.
Many of us, for example, before leaving the office, we remove the laptop from the docking station or disconnect it from the screen, place it in the bag of our bag and we are ready for the way home or… just for the next room for those who work from home. The screen stays in place and we often let it "sleep" on its own - no lullaby, no goodnight, nothing; we just leave.
"Typically, we choose sleep mode for convenience, to quickly reboot the device and get back to work without the delay of restarting the operating system," says Tony Anscombe, head of public security information at company ESET cyber security.
"But the standby mode that a monitor returns to means that it usually consumes about 0,5 W, 4 kWh per year. And of course, the older the device, the more energy it is likely to use, as it may not comply with regulations such as the European Union's EcoDesign directive.
"Let's suppose now that o latest technology equipmentς που χρησιμοποιεί ένα ζευγάρι στο σπίτι και στο γραφείο περιλαμβάνει δυο displays, two laptops, two phone chargers and a docking station and that these remain in standby mode,” says Tony Anscombe.
“Suppose, also, that in an area with a population just under eight millions as is the Bay Area on USA where I live with my wife, 30% of the population puts the 4 4kWh appliances on standby, then 38,4 million kWh are wasted. Considering a typical energy mix, this creates a carbon footprint of 15 tonnes of CO2 emissions per year. Can you calculate what this means for an entire country, continent or even worldwide?” concludes the ESET expert.
All of these devices could be unplugged when we leave the workplace at the end of the day.
For that, these Christmas as you move away from your workplace, whether at home or in the office, to return after the holiday season, unplug appliances – it's both cost-effective and better for the environment.
