In France, it is estimated that a nuclear reactor operates permanently to ensure the watches of our devices. In addition to this waste of energy, watches are also real sources of savings in our housing. Here are practical solutions to detect, quantify and delete the watches of our devices.
- Standby devices, a real source of savings
- Quantify potential savings with energy meters (or consometers)
- How to avoid the watches?
- Our tests of so-called “smart” plugs
- Reduce your electricity bill

Standby devices, a real source of savings
A device sometimes consumes more in standby than when it is running …
On some devices, the standby power consumes more power than when the device is running. For example (list below), a TV that consumes 70W on and 4W on standby will consume 0.07 kWh / day with 1h of operation and 0.09 kWh / day for 23h of standby, or nearly 30% more ! By eliminating the standby period, more than 50% of the annual consumption of the TV is saved here!
1 watt = 1 euro
With such discrepancies, we quickly understand that we must avoid as much as possible to put these devices in standby. This is all the more telling that you have to bear in mind that 1 Watt consumed for a whole year represents more than 1 €. When we know that some devices consume more than 10W in standby, the electricity bill can drop significantly avoiding the watches.
The wrong stop
You might think that turning off your computer or TV completely is enough. However, this is not always the case, in fact, most devices have a small electrical transformer (which goes from 230V AC to 12V DC for the most part). But if they are connected and even connected to any device, you will notice that they heat anyway. They do indeed work permanently (but not at 100% of their capacity) as soon as they are connected. This is therefore additional unnecessary electricity consumption and therefore again to avoid as much as possible.
