Russians are waiting for current therapy

How much electricity is necessary to modern man, not to feel in the middle Ages? And will be able to meet even the most modest citizens in the scope of offered power?
With these questions, we turned to the experts mosenergosbyta. The data obtained was transferred to a unit of measure that is used in our receipts, — kW/h. Recall that, in houses equipped with electric stoves, 1 kWh costs 3 roubles 52 kopecks, in houses with gas cookers — 5 roubles, 03 kopecks. for single-rate counters. Per unit time we took 1 hour, so that readers may choose to divide, multiply and add up.
Of course, for some devices it is difficult to determine the exact figure because different times and in different modes, they consume different amounts of electricity.
— Refrigerator — the most energy-intensive appliance in our household because he works all day and night, constantly turning on and off, — told «MK» chief specialist of the center for energy conservation mosenergosbyta Mikhail Muravyov. — Its capacity at the time the compressor is on average 0.1 to 0.2 kW. If the housing is heated, for example, under sunlight or the refrigerator is at the plate or battery, power consumption is increased by 30%. The old type refrigerators «ZIL», «Minsk», «Biryusa», «Saratov» consume 2 times the power, meaning their power consumption is 0.6 kW. This is because often the compressor, and because old refrigerators have low energy efficiency class. The fridge takes 30% of all consumed in the house electricity.
30% of electricity necessary for lighting, since being on the 56th latitude, we use artificial light for 1500 hours in a year. Another 30% takes an electric stove. And only the remaining 10%, usually accounts for the remaining appliances.
Because the compressor of the refrigerator is switched on only when the appliance considers it necessary to lower the temperature, that is not always appropriate to use average figures specified by the manufacturers. When energy efficiency class B — 445 kWh (per year), A — 376 kW And+ — 248 kW.
Cookers consume 1 kW/h per burner regardless of, whether you have an induction cooker or an old, cast iron «pancakes». Induction just makes it much faster and therefore is more economical. So, five liters of water on a conventional stove to boil for 20-30 minutes, and on induction for five and a half.
Difficult to determine how much consumes the washing machine, because the working conditions vary from 35 minutes, with the temperature of heating water to 40 degrees (requires 0.5 kW/h), up to 2 hours of soaking, wash at 90 degrees and drying (8 kWh). The most commonly used wash cycle, according to the specialist, is 1-2 hours at a temperature of 40 degrees (1-2 kWh per 1 hour of washing).
Working computer monitor consumes 0.1 kW/h — if you check my email, prints the text «walk» on the Internet. But, once you start to work in the graphical editor, watch the movie in high quality or play the game with a big load on the graphics card, the power consumption is doubled to 0.2 kWh. Laptops are less powerful — 0.05 kW/h.
The TV, which is so like our pensioners, is also not the easiest device. The old lamp consumes per hour 0,15 kW, small LCD — 0,05 kW, and that’s a huge «plasma» — 0.2 kW.
It is clear that the family structure strongly influences the amount of consumed kilowatt. Try to calculate the «electric» minimum for a modest family of two Moscow pensioners. So: old television (8 hours per day), 3 fluorescent lamps (8 hours per day), fridge (let it be new, maybe good at grandma’s grandchildren), electric cooker (4 hours a day — Breakfast, lunch, dinner, Oh and to drink tea), Laundry service (4 times per month for 1.5 hours), iron (4 times a week for an hour), vacuum cleaner (4 times per month at 0.5 hours), total sum amounts to no less than 250 kWh per month. Of course, we took into account the winter when it is dark outside and for a walk not pull. But our brave pensioners somehow manage to do 100-150 kWh per month even if the household appliance. Apparently, they’re watching evening TV in the dark, we walk a lot, manage to keep clean with a broom and dustpan, hot water for tea, once boiled, keep it in a thermos, and my few belongings washed by hand.
And now for a real example, let’s calculate how much energy that takes the family of five with two children. The apartment has three computers, two TVs, two refrigerators and a washing machine that runs five times a week. One of the adults constantly work on the computer at home. The end result is that less 360 kWh per month (at a conservative estimate!) to use will not work. Really we are talking about 500-600 kW (again without much glamour). Meanwhile, the authorities now decide whether to limit the ratio of 50 kWh per month per person, or allow all people to freely spend 150-190.
However, experts mosenergosbyta gave some advice on energy saving. For example, to set createreply counter (it will cost 4200 rubles) and run washing machine and dishwasher and slow cooker at night, plus configure all of the computers power-saving mode and replace all bulbs to led.
By the way, in the Wake of the crisis in Moscow intensified the scammers, offering to citizens the so-called «energy Saver» device, which supposedly helps to reduce the consumption of electricity. Staff mosenergosbyta tested this device on their equipment and have even taken it apart. Nothing, except the bulb, it was not. I should add that the «energy Saver» not only saves electricity but also releases it, and the light’s got to Shine…
