Secret Eaters

    I turned off the light, “put to sleep” the computer, pulled out the refrigerator from the outlet and looked at how much electricity the meter shows.

    80 watts This is 700 kWh per year, for which you have to pay up to 3525 rubles!

    In any modern apartment, the network constantly includes many devices operating in standby mode. Although they are turned off, these devices consume some of the energy needed to turn on from a remote control or button.

    Usually, on the blog, I talk about LED bulbs that consume 6-10 times less than traditional ones and can significantly save on electricity costs. Today I want to touch on another aspect of saving.

    At home, I found 28 devices that were plugged in and consumed electricity. I measured their consumption in standby mode using a power meter .

    Boneco air purifier - 0.4 W (10.28 rubles a year)
    Openbox satellite receiver - 5.7 W (167.01 rubles a year)
    Xbox 360 game console - 0.7 W (20.51 rubles a year)
    Yamaha 861 receiver - 0.1 W (2.93 rubles a year) per year)
    Panasonic 50ST30 Plasma TV - 0.3 W (8.79 rubles per year)
    Pioneer 575 DVD player - 0.1 W (2.93 rubles per year)
    Computer in sleep mode - 1.3 W (38.09 rubles per year)
    Viewsonic VA926 monitor - 0.7 W (20.51 rubles per year)
    Notebook - 0.5 W (14.65 rubles per year)
    The lifting base of the Ikea bed is 2.8 W (82.04 rubles a year)
    The second lifting base of Ikea is 2.8 W (82.04 rubles a year)
    Philips light alarm clock is 1.7 W (49.81 rubles a year)
    Sony 26 "LCD TV - 0.2 W ( 5.86 rubles a year)
    Pioneer receiver - 1.2 W (35.16 rubles a year)
    Radio alarm clock with a Vitek projector - 1.7 W (49.81 rubles a year)
    Delonghi ESAM-2600 coffee machine - 1.3 W (38.09 rubles a year)
    Philips LCD TV 20 "- 1.0 W (29.3 rubles a year)
    Cremesso Uno coffee machine - 0.2 W (5.86 rubles a year)
    Sony HX30 music center - 0.1 W (2.93 rubles a year)
    LG 12400NDK washing machine - 0.1 W (2.93 rubles a year) per year)
    Samsung Air Conditioner - 1.1 W (32.23 rubles per year)
    Hitachi Inverter air conditioner - 5.6 W (164.08 rubles per year)

    In addition, there are several constantly working devices at home:

    Zyxel Keenetic router - 3.5 W (102.55 rubles per year)
    Switch D-Link DES-1024D - 2.8 W (82.04 rubles per year)
    Video surveillance system (recorder and 4 cameras) - 16.2 W (474.66 rubles per year)
    Charging station for a Gigaset cordless telephone with a fully charged phone on it - 0.6 W (17.58 rubles per year)
    Gigaset cordless telephone base - 1.2 W (35.16 rubles. per year)
    The CO2 level meter - 0.4 W (11.72 rubles per year)

    In total, 54.3 W was obtained, but the meter has a measurement accuracy of 0.1 W and may be wrong. Measurement graduation at the counter 0.02 kW (20 W).

    I pay for electricity 3.90 rubles. from 7.00 to 23.00 and 1 rub. from 23.00 to 7.00 (two-tariff accounting for houses with electric stoves), the maximum tariff in Moscow is now 5.03 rubles. (one-rate accounting for houses without electric stoves).

    Thus, the 700 kWh that these devices consume costs me 2055 rubles per year.

    Surprisingly, the most gluttonous in standby mode was a small satellite receiver. I use it only a few times a year, so of course I immediately turned it off, as did half of the devices listed. Consumption halved.

    At the same time, I measured the consumption of several more devices:

    Technics CD player - 3.1 W
    Toshiba DVD recorder - 6.8 W
    Computer in off mode - 0.8 W
    Laptop memory - 0.2 W

    I wonder how the Panasonic and Sony TVs behave, as well as the LG washing machine. After shutdown, they consume quite a lot (Sony LCD 17.2 W, Panasonic 50ST30 plasma TV - 13.9 W, LG 12400NDK washing machine - 3.0 W), but after a few minutes the relay clicks in them and the consumption becomes very low (0.2, 0.3 and 0.1 W, respectively) )

    But the consumption of some devices in the operating mode:

    Panasonic 50ST30 plasma TV - 270 W
    Viewsonic VA926 monitor - 25.4 W
    Computer (Pentium G3258 / 8Gb / 128SSD + 1500HDD) - 30 W
    Notebook (Core i3 / 4/500 / nvidia) - 66 W

    Take a walk around the house and see what you have on the network. Using an electric meter, determine how much your appliances eat in standby mode. To do this, at a regular counter, you need to measure the number of disk revolutions in 5 minutes, divide by the indicated number of revolutions per kW * H (for example, 1280 revolutions per kW * H) and multiply by 12 (the number of five-minute intervals per hour). Electronic meters can show the current consumption (on mine you need to press the top button once).

    It may be time to turn off most of them and turn them on only if necessary, and at the same time reduce the risk of fire due to devices that are constantly connected to the network.
