In the midst of the energy crisis, all ecological and economic actions now pay off. To save electricity, some recommend unplugging all chargers once the batteries for various electronic devices are full. A reflection that is often recommended, but has a very limited ecological impact.
• Unplugging the charger saves energy
it’s true but…
As the Agency for the Environment and Energy Management (Ademe) reminds us, a charger tends to consume electricity, even when it is not powering any smartphone or computer. The organization has regularly communicated about the issue, including on social media, to warn users.
To find out the extent of this cost, simply connect a wattmeter that measures the amount of electricity consumed by a “no load” charger. An operation mentioned by Engie, who carried out the experiment.
The energy provider estimates that six chargers connected to a power strip consume a total of 0.3 watts per hour. That is 2.6 kWh per year. At an annual rate of 18.22 cents per kWh charged by EDF, the cost of six permanently connected chargers is therefore 47 cents per year.
Keep in mind that the tests carried out refer to smartphones and were published in 2020. However, mobile manufacturers, offering ever faster charging options, periodically increase the power of these chargers, as do cell phone manufacturers. tablets and computers. This could have the effect of increasing this unnecessary consumption. If unplugging your chargers will only have a very limited impact on your electricity consumption, it’s hard not to recommend this extremely simple gesture.
