Electricity bills often hide consumption that was not planned, we are probably not very careful about the use of the devices we bring into the house. Some even when turned off consume more energy than you imagine, which is why it would be advisable to turn them off.
What you don’t know, or perhaps know but forget, is that certain electrical appliances, even when turned off or in standby mode, consume on average around 1.6 kilowatts per day in a home. This means between 5% and 10% of the energy expenditure of more than one family.

1. Cable box: Devices that provide cable or satellite TV service have different power consumption. The one that consumes the most, according to the study, is the one with the “video recorder” mode.
2. Laptops: The laptops we have at home can consume up to 8.9 watts per hour. In standby or hibernation mode, this consumption can reach 15.7W.
3. Music device: if the device integrates the radio and remains on, the consumption reaches 14.4 w.
4. Desktop computers: If you leave the PC in sleep mode, the consumption increases to 21.1 watts and if it is turned on without utilities even if the monitor is off, it can consume 73.9w.
5. The coffee machine: consumes a little more than 1w/hour when plugged in without use. While the game console: when it is turned off and remains connected, it consumes around 1w, but if we leave it in “ready to use” mode, it increases to 23.3w.
6. Television: LCD screens tend to consume less power. However, some models can consume twice as much as the old cathode ray model.
7. Microwave oven: this appliance multiplies its consumption up to 8 times if the door is open. Consumption is 3.08 w, but with the door open it is 25.79 w.
8. Cordless telephone: if the telephone has an answering machine, consumption can reach 2.9w/hour.
9. Chargers for mobile phones: this is the one that consumes the least. However, you don’t need to leave it plugged in when you’re not charging your phone.
In short, before going to bed perhaps it is better to take a walk to unplug the devices that you do not need.
