Savings are always welcome and more so if they has a direct impact on your hip pocket, so it is very common to consider whether it is necessary to have them plugged in all the time and if it is really worth unplugging all of them or leaving them in eco, stand-by or “low consumption” mode.
The reality is that today’s devices are quite efficient in terms of their energy expenditure when in “sleep” mode.
We are talking about so-called “phantom consumption” and it costs you a whopping €5 per month and between 7% and 11% of the total electricity cost of a house. You can read more about phantom consumption in this other post.
You don’t use them, but they suck energy from your current and euros from your pocket.
However, many of them are totally necessary or not worth unplugging because their use is quite common or even continuous.
For example, there is an urban myth that states that phone chargers use a lot of power when you leave them connected and do not plug in the phone. The truth is that individually they do not consume as much.
But is it possible to spread the blame around and find the biggest power drain?
