How to save electricity (electrician tips)

Electricity — the benefit of the civilization, but the cost of a kilowatt-hour is gradually increasing, and the energy conservation are becoming increasingly acute and important. What measures can be take each of us to save is not an extra penny? Try to understand!


The culture of using equipment and appliances

To start with, that virtually no one that — the disconnection of the network chargers, Televisions, household appliances. Charger left in the socket, it is still working, and that is called inactive, and the current consumption is based on the system of circuits and the power of the device. Is any type of sources of energy such as a transformer, and the pulse. In any modern household appliances, for example, in the microwave oven, the conditioner, the TV or the TV tuner has indicators, displays, LEDs, and They consume energy, and the energy source, for example, when the TV is off with "remote" continues to run in standby mode. Standby is standby, the equipment, the wait can signal the remote control, or set the timer hours. On this subject the network has a large amount of research, we have collected and an average of the data obtained on the consumption of some devices in idle or in standby mode) and mix them in a list:

  • Satellite receiver or TV tuner digital — 5.7 W (50 kWh/year);
  • - Game console — 0.7-1 W (8,7 kWh/year);
  • - TV — 0.3-0.5 W (4,4 kWh/year);
  • The computer is in a mode of hibernation 3-4 watts (35 kW/year);
  • - Monitor — 1W (8,7 kWh/year);
  • - Laptop — 0.5 W (4,4 kWh/year);
  • - Coffee maker — 1.5 W (13 kWh/year);
  • - Washing machine — 0.1 watts (0.9 kW/year);
  • - Air conditioning — 3-5 W (44 kWh/year);
  • Router (he's always in a running mode, not in standby) and 3 to 5 W (44 kWh/year).

If in each case the figures are not especially saving, but the amount of work a considerable number. In addition, any unused appliance that you leave connected to the network is a danger of ignition and of fire. So unplug appliances if you are not using them. You should also not keep the PC or laptop at all times. A computer monitor can consume 100 watts or more, even if only idle (and during the games, the consumption can increase to half a kilowatt), the average laptop is 40-60 watts. By the way, it is possible to conclude that, if there is no need for a stationary machine portable burn a small amount of electricity during operation. However, if you don't need a computer or laptop computer, send it in sleep mode or hibernation, then your consumption will drop to a few watts. The same applies to tablets and mobile phones. Access to the site statistics show that the majority of traffic in 2019 – mobile device. In addition to the small size and autonomy of the note and profitability. For example, in the tablet installed battery capacity of almost 9000 mA/h, voltage of about 3.7 V, which tells us that it is stored power up to 33 W/h. the Manufacturer claims up to 10 hours of continuous operation, which is confirmed by the test observers. What does it mean? The fact that a full charge takes up to 40-50 Watts of electricity, taking into account the efficiency of the battery charger and the consumption of the tablet during the charging process. This energy is enough for a full day of work or surfing the Internet, then as a full-fledged computer, it consumes two more per hour. It is in any case not advertising Apple equipment from the manufacturer, but only an example. The same can be said about any other type of device may differ only in the number of hours of work and the amount of watts needed for this. Prioritize and clearly define what the device enough for the job.

Before you leave turn off the light!

If in 2019 it is difficult to say something new about the efficiency of led and fluorescent lamps, it will not be superfluous to remind about the need to use lighting efficiently. Forgotten for the night lighting significantly hit in the pocket, even using led lights. Suppose you let a night light in the bathroom or in the hallway, how much is it? If we are talking about the led lights, the greatest demand is for light bulbs with a capacity of 7 to 10 watts, will have a large value. Before you go to sleep you forgot to turn it off or purposely leave the lights on in a room, people sleep about 7-8 hours, then:

10*8 = 80 watts/hour for evening and natural light, and in the year:

80*365=29.2 kWh

But if the lights are in different rooms all night? But added to this device is in the standby mode, about which we have talked about before? If you're using incandescent bulbs– these numbers can be multiplied more than 10 times. In addition to the neglected light bulbs not all people understand the difference between General and local lighting and chandeliers turn on powerful lights. Significantly reduce the cost of the lighting, if you use a table lamp, and General (overhead) lighting to be less bright. This will help you a dimmer or a breakdown of the lighting in groups. Also install motion sensors to light in these rooms helps to save money, how to do it we spoke in another article.


The installation of tariff meter very significantly helps to save money. There are several options – two area and three area of billing. For example, this type of rates:

  • - For a fee, meter is 5.38 p per 1 kW/h
  • For two of the area of fixation of prices: night (23:00 to 07:00) of 2.29 p for 1 kW/h a day (from 07:00 to 23:00) 6.1 p per 1 kWh;
  • For three tariff meters night of 2.29 R, the half peak area (at the end of the afternoon and at night, from 10.00 to 17.00 hrs and from 21.00 to 23.00) is 5.38 R and peak hours (morning and evening from 07:00 to 10:00 and from 17:00 to 21:00) to 7 rubles per 1 kW/h.

Who benefits? Almost everyone who works a day job and a night at home – the cheaper of the Buddha, wash, bathe (if you're using an electric water heater), cooking (if electric stove). Also many of the rates tab is to reduce the amount of over heating, if you have a private house or apartment with electric auxiliary heating system (induction boiler, boiler with Heat Energy by Heaters, etc.). So you can, while you are not at home, which reduces the capacity of the boiler or disable it (with a mild cold), and go home to turn on and all night to heat the house. Using a Wi-Fi relay, or timer, or other means of home automation to make this process automatic, that is to say, the power can be adjusted without your participation. That is to say, you can configure the inclusion of heating for an hour before coming to work, not to go in the cold apartment.

Energy efficiency

The concept of energy efficiency is large enough and in the eyes of ordinary people is uncertain. In most cases, under the energy efficiency and energy saving to the people to understand the installation of led or energy-saving bulbs, and buy LED Tvs and monitors. However, it is not so. Energy efficiency improvement is one of the main contemporary tasks of scientists and engineers, and applies both to exploit the potential of new technologies and devices with different from old actions (same inverter motors for compressors of refrigerators, washing machines, or led light sources) and a different approach to the usual control elements and circuits, as well as the improvement of the switching frequency power sources, the optimization of the operation modes of the semiconductor switches with the aim of increasing the efficiency of the instrument as a whole. Therefore, all of the material is divided into classes of energy efficiency, which is denoted by the letters a to G, but most of the current devices with higher classes A+, A++ and A+++, and that are described in this document as "the Directive on the marking label, the energy efficiency No. 2010/30/EU".

The energy efficiency class is determined on the basis of the volume of electricity consumed in the process and other factors, for each type of technology has its own scale. We will not go into detail we show the difference of classes in a real-life example. In selected 2 different refrigerator with good reviews and rating, but a different class of efficiency. The difference in consumption almost in 2 times. But the price is half. But with the modern technology of the "energy efficiency" is not limited. To save energy, it is important not to waste energy in vain. This is especially true for those who heat their homes with electricity. If you have a thin wall and pulls out from under the baseboards and Windows – no matter what the boiler and rational how to make the circuit of heating – will still be by the heat of the street! Insulation, sealing of joints, use of modern materials in the construction significantly reduces the loss of heat. To give specific figures are unsustainable because they depend on the specific house and other factors such as the quality of the union of the walls, stacking blocks, sealing of all the places where you can blow (cold bridges) and giving the frequency and the strength of the wind in your area.

Five rules to save

So, to summarize:

  1. 1. Unplug appliances and chargers of the network, we do not want every time to pull the plug? There are extension cables, plugs, and even plugs with switch.
  2. 2. Use the energy saving or led light bulb.
  3. 3. When buying a new fridge and washing machine, pay attention to the technique of the highest class
  4. 4. Install many corresponding rate.
  5. 5. Inspect the house for heat loss (there are a lot of professionals also offer inspection with a thermal imager) and isolate the problem areas.
