Electricity — the benefits of civilization, but the cost of a kilowatt-hour is gradually increasing and energy saving are becoming more acute and important. What measures can be taken, each of us saving is not an extra penny? Try to understand!
Cultural use of gadgets and home appliances
At first, with practice, one doesn't do it — disconnect from the mains chargers, Televisions, home appliances. The charger went in the outlet, still works, it is called idle, and the power consumption depends on the circuit and power the device. It has any power sources, such as the transformer, and the pulse. Any modern home appliances, for example microwave, conditioner, TV-in or TV-tuner's indicators – display, Led-lights, and so They also consume energy, and the power source, for example, when the TV is switched off and the "remote" continues to operate in the standby mode. In the standby mode, the standby mode of the devices, wait, it can signal the remote control, or set the timer for an hour. This topic network is a lot of research, we collected and averaged the data obtained on the consumption of some devices in sleep mode or standby mode, and mixed them together in a list:
- Satellite receiver or tuner in digital TV 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 hibernate mode, 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 w (0.9 kW/year);
- - Air conditioning — 3-5 W (44 kWh/year);
- Router (he is always running mode, not standby) and 3-5 W (44 kWh/year).
If in each case the figures are not particularly savings, but the amount of work a considerable amount. In addition, unused equipment that you leave connected to the network, there is a danger of ignition and fire. So unplug the devices, if you don't use them. You should also not keep your COMPUTER or laptop all the time. The computer screen can consume 100 watts or more, even if only idle (and during the games, consumption can increase and a half kilowatt hours), the average laptop is 40-60 watts. By the way, it is already possible to conclude that, if there is no need for a stationary machine – the laptop will burn a smaller amount of electricity during operation. If you don't need a computer or laptop computer, send it to sleep or hibernate, so its consumption drops to a few watts. The same applies to tablets to mobile phones. Site access statistics show that the majority of the traffic in 2019 – mobile device. In addition, the small size and independence note and profitability. For example, the tablet installed battery capacity of almost 9000 mA/h, voltage of about 3.7 V, which tells us that it is the stored power of 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 lasts for up to 40-50 Watts of electricity, taking into account the efficiency of the battery, the charger and the consumption of the tablet during charging. This energy is enough for a full day of work or surfing the Internet, as a full-fledged computer will consume two more per hour. It is in any case not to advertise Apple devices from the manufacturer, but just an example. The same can be said for any other device differ only in the number of hours of work and the amount of watts required for this. Prioritize and clearly define which device you have enough work.
Before leaving, extinguish the light!
If the year 2019, it is difficult to say something new efficiency led and fluorescent lamps, it is not superfluous to remind of the need to use lighting effectively. Forgotten night lighting significantly hit the wallet, even when using led lamps. Let's say, you can leave it for a night light in the bathroom or in the hallway, how much is it? If we talk about the led lamp, the greatest demand is for lamps with a capacity of 7-10 watts, will take a higher value. Before going to bed you forget to turn off or deliberately left the lights on in the room, people sleep about 7-8 hours, then:
10*8 = 80 w/hours per night and natural light, and years:
80*365=29.2 kWh
But if the lights are on in several rooms throughout the night? But added to this devices are in standby mode, which we talked about above? If you are using incandescent bulbs – these figures can be multiplied 10 times. In addition to the neglected light bulbs are not all the people understand the difference between General and local lighting and chandeliers spiral powerful lamps. Significantly reduce the cost of lighting, if you use a table, lamp, and General (overhead) lighting is dimmer. This will help you dimmer or distribution of the lighting group. There are also motion detectors to light these areas to help save money, how to do it we spoke in another article.
Counter
The installation of tariff meters a lot to help significantly save money. There are several options – two-zone and three-zone billing. For example, such prices:
- - One-tariff meter is 5.38 p per 1 kW/h
- Two-zone pricing: night (23:00 to 07:00) to 2.29 p / 1 kW/h a day (07:00-23:00) 6.1 p per 1 kWh;
- Three tariff meters night 2.29 R, half peak area (late afternoon and evening 10.00-17.00 and 21.00-23.00) is a 5.38 R and peak times (morning and evening 07:00 to 10:00 and 17:00-21:00) 7 rubles per 1 kW/h.
Who benefits? Almost everyone who works a day job, and in the evening at home – cheaper Buda washing, bathing (if you're using an electric water heater), cooking (if electric stove). Also many of the customs of the counter to reduce over-heating, if you have your own house or apartment in which an additional electrical heating system (induction cooker, boiler, Heat Energy Heaters, etc.). So you can, when you're not home, lowering the capacity of the boiler or disable it (a mild cold), and came home on top and the whole night a warm home. Using a Wi-Fi relay, or timer, or other means to home automation, so this process is automatic, that is, the output will adjust without your participation. That is, you can specify the inclusion of heating for an hour before coming to work, not go to the chilled 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 savings, people understand the installation of led or energy-saving bulbs, and buy LED Tvs and monitors. However, it is not so. Improving energy efficiency is one of the main contemporary tasks of engineers and scientists, and it applies as well to take advantage of new technologies and devices, which is different from old actions (same inverter motors-compressors, refrigerators, washing machines, or led-light) and a different approach to the usual operating elements and circuits, such as improved frequency of switching power sources, optimization of operation modes of the semiconductor switches, the purpose of which is to increase the efficiency of the instrument as a whole. I saw all the equipment is divided into categories of energy efficiency, it is marked with Latin letters A-G, but most of the current devices with higher classes A+, A and A+++, and they are described in this document, such as the "Directive on the label energy efficiency No. 2010/30/EU".
The energy efficiency class is determined on the basis of the amount of electricity consumed in the process and other factors, each type of technology has its own scale. Don't go into the details, we show the difference in class to a real example. Yandex.the market has chosen 2 different refrigerator and good reviews and rating, but in a different class of efficiency. The difference between consumption almost in 2 times. But the price is half. But modern technology "energy efficiency" is not limited. To conserve 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 thin walls and pull from under the baseboards and Windows – no matter what boiler and how reasonable you make the heating circuit – still heat in the street! Insulation, sealing of joints, use of modern materials in construction significantly reduces heat loss. To give exact figures are unsustainable, because they depend on the particular house and other factors, such as the quality of the joining walls, stacking blocks, sealing in all the places where it can blow (cold bridges) and by giving the frequency and intensity of wind in your area.
Five rules to save
So, in summary:
- 1. Unplug appliances and chargers from the network, do not want to always pull the plug? There are extension cords, plugs, and even plugs to change.
- 2. Use energy saving or led bulb.
- 3. When you buy a new refrigerator or washing machine, pay attention to the technique top-notch
- 4. Install multi-tariff meter.
- 5. Check your home for heat loss (there is a lot of professionals also offer inspection with a thermal camera) and isolate problem areas.
