Internet box, voice speaker, television… With the right settings, you can save 10 to 20% on your electricity bill. And strive for more sobriety.
They are now everywhere in our daily lives: televisions, computers, internet boxes, smartphones, smart speakers, tablets, connected light bulbs, etc. And all of this ends up weighing on our energy bill. It’s no coincidence that household electricity consumption increased by nearly a third between 1990 and 2010 (source: RTE). The proliferation of electrical appliances, their uses and their time of use increasingly weigh in the balance.
And if certain technologies, such as LED lighting, are less energy intensive, these savings are canceled out by a higher level of equipment (multiplication of smartphones in the home, devices that are always on standby when fully they were off before, etc. ). According to Ademe, an internet+TV box consumes 150 to 300 kWh/year, a laptop from 30 to 100 kWh/year, a smartphone from 2 to 7 kWh/year… At the time a certain sobriety, there are solutions to reduce their energy consumption.
Internet box: making the right choices
The first thing to do is list the devices that regularly connect to your home’s wifi network or use the box’s connection in one way or another. There are obvious devices like smartphones or computers, but you also need to think about your possible smart speakers, connected light bulbs and all home automation.
Do you have a thermostat controlled by an app? Shutters or blinds connected to an automated system that can be controlled remotely? It should be checked that changing the parameters of the box will not affect (too much) this equipment.
You can think of cutting the wifi during the day when you are in the office, or at night, after a certain time. The procedure will not always be the same depending on your operator (Orange, Libre, SFR, Bouygues Telecom), but the principle remains the same: adjustments to be made in time slots. It is also possible to activate or deactivate these parameters manually at any time in your access provider’s application. Useful for example if you leave for the weekend and forget to unplug the box, which is still the best option for real courage.
Screen: lighting measurement
To reduce power consumption, it can be useful to adjust the brightness of home screens so that they are no longer at maximum, but a little lower. Changing the brightness of your smartphone, computer or television from 100% to 70%, a level that remains comfortable in most cases, can reduce their electricity consumption by up to 20% (source: Harvard University). It’s also good to know: the higher the surface of your television, the higher its consumption. A small size in this area is desirable when buying…
On a computer, whether fixed or portable, remember to check the screen saver settings. Opt for the clearest and darkest display possible, or even put it on standby if the device hasn’t been used for 5 minutes. You can also, depending on the model, adjust the settings differently depending on whether the device is connected to the mains or to the battery. In the latter case, the systematic activation of the “energy saving” mode can be a plus to save a little more on the electricity bill.
Equip yourself with connected sockets
In France, electrical appliances on standby make up about 11% of each household’s average annual electricity consumption, according to Ademe. Obviously there’s television, which comes first, but smart speakers are also connected, for example. To avoid going around the apartment or house to unplug all the devices when you leave your house, it is a good idea to have connected sockets (or power strips), which are connected to your home system. smart.
Whether you choose Apple HomeKit, Alexa or Google Home – for the most popular – there are compatible sockets. Once installed and connected to one of the platforms, all you have to do is create a “routine” (or “scene”, or “automation”, sometimes the vocabulary is different but the principle remains the same) to optimize your electricity usage. When you get home, these sockets light up (so restart your turned off devices). On the contrary, when you leave the household (that is to say that your smartphone goes away from it), they will turn off. There is always the possibility to control them remotely via smartphone.
