The devices that consume most on stand-by
Estimating stand-by consumption is complicated, given that it significantly depends on the model of home appliance used and its energy efficiency, but approximate measurements can be calculated.
We’re not asking you to go crazy. We’re just pointing out the devices that are consuming the most phantom consumption for you and that would be best to entirely turn off when you're not using them.
It is one of the elements in your home that consume most on stand-by, particularly if they have a recording system with a hard drive.
They can consume between 41 and 64 kWh per year. This represents an annual cost on your bill of approximately 7 – 10 euros.
They are one of the electronic devices that we most commonly leave plugged in. Some people leave them constantly plugged in... just in case.
A laptop that is entirely turned off, consumes around 35 kWh per year just by being plugged in, which on your bill can reach up to 6 euros.
Mini music systems
Music equipment is similar to laptops. Consumption is around 53 kWh and take around 9 euros per year out of your pocket.
As we said above, having the television on stand-by during its entire useful life is a classic.
A 32-inch CRT monitor can spend up to 53 kWh per year on stand-by (about 9 euros), while a 37-inch LED monitor reduces this consumption to 18 kWh per year (less than 3 euros).
A 42-inch plasma television has a phantom consumption of 26 kWh per year, which on your bill translates into approximately 4.5 euros.
Keep in mind that the old rear projection monitors consume more than the current flat screens.
This home appliance has a phantom consumption that reaches 35 kWh per year. For that reason, you must be careful to leave it turned off when you're not using it, given that you can save up to 6 euros per year.
How much phantom consumption costs you
Estimating the cost of phantom consumption on your bill is complicated, given that the price of the kWh entirely depends on your electricity tariff, but we can calculate averages inspired by the reality of the market.
If we add it all up, just with the aforementioned devices that are present in most homes, we get a total of approximately 377 kWh. By turning them off, you can save up to 64 euros per year—more than 5 euros per month.
We could also expand the previous list to include wireless telephones (around 6 euros per year), the coffee maker (7.45 euros per year) and video game consoles (practically 6 euros per year). Interestingly, of all the things you have at home, cell phone chargers consume the least in phantom mode. Still, you should unplug them if you’re not using them, even if it’s just for the sake of safety.
