Here’s a very useful tip to save a few euros at the end of the year: invest in power strips with a switch. Indeed, between the permanently plugged-in laptop chargers, the lamps… We have devices plugged into our power strips. We know it well, we don’t take the time to unplug them in the evening. The solution, the multiple socket with switch. Just one button to turn off in the evening, it’s much simpler. According to ADEME, this would save up to 10% of your annual electricity bill. Not bad is not it ?
