How much do these appliances consume?
Many appliances have a so-called “phantom consumption” when they are on standby, in suspension, and ready to reactivate. Here’s how much they cost us.
Our homes are full of electronic devices they consume electric current even when they are turned off or they seem so, between stand-by, suspensions e smart connections which ensure quick reactivation at the push of a button. It is therefore worth taking into consideration which devices are “off” the most energetic and taking appropriate measures to avoid paying the so-called phantom consumption.
Moreover, in recent months, the significant increase in the cost of energy has made them skyrocket bills, with a further increase expected for the cold season at the turn of 2022 and 2023. It is a real drain that risks – literally – upsetting the economic balance sheets of families and companies, so much so that we even start talking about the risk of “deindustrialization”. Some have already decided to stop production, in order not to pay the exorbitant figures that have jumped to the honors of the national news in recent weeks.
It is no coincidence that the government is thinking of targeted solutions to contain energy prices (linked to gas) and protect certain groups. In light of this delicate situation, it is first of all possible to intervene on electronic devices that consume more even when switched off (but this should always be done). Here’s what they are.
An interesting overview of these devices was made by the “Take control and save” portal which aims to promote energy efficiency and reduce waste. Consuming energy unnecessarily, after all, is another way to increase the emissions in the atmosphere and catalyze global warming, the main threat facing humanity.
Televisions, DVD / Bluray players, set-top boxes, video game consoles, chargers, computers, printers, coffee machines, smart speakers, toasters, and many other devices (especially “smart” ones) continuously consume power, even if they are not in operation and fact, they seem dull to us.
Bearing in mind a (very low) rate of only 10 cents per kilowatt hour (kWh), an LCD TV under 40 inches has a monthly ghost consumption of approximately 4,40 kWh for a cost of 22 cents per month e 2.63 Euro per year. And DVR player is more energy-intensive and has a phantom consumption of 27 kWh per month (over 320 per year), equal to 2.70 euros per month and almost 33 Euros per year. An audio system consumes almost stand-by 6 kWh per month, with an expense of 0.6 Euros per month e 7 Euros per year.
Even a desktop system (computer, speakers, and monitor) consumes almost 6 kWh per month, at an expense of 7 Euros per year. The modem/router for the connection consumes 3.65 kWh and has a phantom cost of almost 4.5 Euros per year. Even the chargers continuously attached to the sockets continue to consume energy, costing us almost 4 euros each year (consider how many are always ready for use, for example, to recharge smartphones and tablets).
Add all these devices together, increase the cost per kilowatt hour to current levels (and those forecast for the next few months) and you will understand how much phantom consumption can impact your bills.
The microwave oven, with 3,08-watt Allora, can reach over 25 if you leave the door open. A video game console and a coffee machine, when turned off, consume 1 watts per hour each, while a laptop in sleep mode can consume just under 10 watts per hour. Even smart bulbs have a phantom consumption that should not be underestimated.
As explained in a video from the ticker enzoj795, a smart light bulb it consumes 0.6 watts when turned off, while the device to make it so (always connected) reaches 2.3 watts. Other lamps and bulbs may have phantom consumptions over one watt.

To reduce phantom consumption Take control and save recommends for example to group some of these devices on multi-socket power strips equipped with a button to turn them off and disconnect them from the power, naturally paying attention to not overload the power strip and respect all the limits of the system and the device in use.
They also recommend that you always unplug chargers from the socket, unplug objects when fully charged (such as a smartphone), eliminate unnecessary night lights, and use as little as possible screensavers and computer hibernation systems, but turn it off directly if you do. drive away for 20 minutes or more. But you must always pay attention to those devices that need to be constantly connected to work properly.
