Power consumption is one of the main characteristics of electrical appliances. Therefore, on any electrical appliance or in the instructions for it, there must be accurate information about the number of watts required for its operation.

Of course, the amount of electricity consumed can vary. For example, the amount of power consumed by a computer depends on the power of the power supply and the workload of the computer. In the case of a refrigerator, it depends on its volume and the amount of food stored in it, and with a washing machine - on the washing mode, set temperature, weight of laundry, etc. The rating below shows the approximate power of household electrical appliances in descending order:

Note that watt (kilowatt) and watt-hour (kilowatt-hour) are two different units of measurement and they refer to different physical quantities. Due to similar names, these concepts are often confused in everyday use, especially when it comes to electrical appliances. In watts (W) and kilowatts (kW), power is measured, that is, the amount of energy consumed by the device per unit of time. A watt-hour (Wh) or kilowatt-hour (kWh) are units of measurement of energy produced or work performed by an electrical appliance, and are mainly used to measure electricity consumption in everyday life or in the economy.

These two quantities are related in the following way. If a 1000 watt air conditioner worked for 1 hour, its operation required 1000 watt-hours (or 1 kilowatt-hour). A 1-watt answering machine will consume the same amount of power in 1000 hours.

100 Ways to Save Energy at Home

The largest German energy company E.ON has proposed some ways and methods to save energy, applicable for domestic use within their home or apartment. They will help us reduce the emission of harmful combustion products and save our money. So, here are 100 tips on how to save energy.

Kitchen

1. Size matters - never put a small pan on a large hotplate - it's a waste of energy and money.
2. Always cover the pan when cooking to save cooking time.
3. Use the inner ring of the hotplate if you have double hotplates on the stove - the food will cook at the same speed, but with less energy.
4. Make sure your gas stove is set for the correct gas flow - if the flame is too high - you can save money here by reducing the flow.
5. Finely chopped food is cooked faster and therefore more economical.
6. Start using a double boiler - you can cook several dishes at the same time using only one heat source.
7. Use energy saving kettles to boil water.
8. Descale the kettle regularly - it is not only harmful, but also forces you to apply more heat to boil the same volume of water.
9. Don't be delayed - many modern stoves have blowing fans, which make the heating process faster.
10. Use the entire space of your stove - you can cook at the same time what you just need to defrost.

11. Use an electric toaster - it will make your toast faster and more economically than any other appliance.
12. Use deep fryers - they are safer and more economical than cooking on the stove.
13. Try a pressure cooker - it cooks faster due to the higher temperatures and pressures inside the pot.
14. Use a slowcooker - you can cook the whole dish in it.
15. If you are looking for a new cooker, try an inductive cooker. They are more efficient, easier to clean and manage.
16. Grill if possible - this speeds up the cooking process and preserves the healthiness of the food.
17. Try to skip simmering.
18. Keep the glass of your stove clean - this will allow you to control the degree of cookiness of the dish without opening the door, thus not releasing precious heat from the oven.
19. Use microwave ovens - they work quickly, efficiently and economically.

Lighting

20. Use energy efficient bulbs - they last 10 times longer and will save you a lot of money.
21. Use fluorescent lights in your kitchen - they last longer.
22. Leaving the room - turn off the light, you lose money, leaving the light on where it is not needed.
23. Equip the luminaires in the stairwell and stairwells with motion sensors - this will allow them to be used only for their intended purpose.
24. Try using low-power bulbs - they will give you sufficient light, but will cost less and consume less.
25. Find an opportunity to install circuit breakers for TV, computer and laptop.
26. Do not leave TVs, DVD-players or computers on "Stand-by" mode, it wastes your energy, which means money!
27. Do not leave or forget electrical devices on charging more than is necessary to fully charge the battery.
28. Use photovoltaic lamps for your yard, they do not consume electricity.

Heat supply

29. Install a thermostatic valve on your radiator, and you will be able to regulate the amount of heat carrier that you consume.
30. Reducing the temperature set by the thermostat by 1 ° C throughout the house will save up to 10% on heat bills.
31. Use window ventilators for ventilation, do not open windows - you lose heat, for which you pay.
32. Avoid installing heaters in drafts.
33. Use underfloor heating to save central heating.
34. Do not use heating devices when you are not in the room.
35. Heat the water with an electric boiler, it will be very economical.
36. Select the size of the heater according to the size of the room, you should not be cold or hot.
37. Do not cover heating devices with clothing or furniture - this makes them less efficient.
38. Avoid overheating at night while sleeping - the blanket will make you comfortable.

39. Remember to check your heating system annually to make sure it is working efficiently.
40. Bleed air from heating devices (batteries) with hot water - this will allow the coolant to circulate fully.
41. Geysers lose their effectiveness after 15 years of operation - think about replacing outdated equipment.
42. When replacing the boiler, you should also change the entire control system.
43. Leave the inner doors open - this will distribute heat evenly throughout the volume thanks to natural circulation.

Hot water

44. Try washing your hands in cold water - this will save a lot of hot water.
45. If you are taking a bath, choose the optimal filling level.
46. ​​Install the sensor on the hot water tap - water will flow only when hands are brought to the tap.
47. Use a bowl for washing dishes in the kitchen - this way you will spend much less hot water.
48. Shower instead of bath - A full bath uses three times more water than a full shower.
49. Use thermal insulation on open pipes with hot water - this will conserve heat and prevent them from collapsing.
50. Boil water in an electric kettle if you need a small amount of hot water.
51. Adequate temperature for hot water - + 60 ° C, all sanitary standards will be met.
52. Remember to close the taps when not in use to ensure that no water is lost.
53. Install sensors-thermostats on your hot water supply system.

54. Consider using a solar hot water system - it starts to pay off from day one.
55. Install meters for hot and cold water - this will allow you to visually study the effectiveness of the measures you have taken to save.
56. If you are leaving, turn off the hot and cold water taps, your home and wallet will be safe.
57. Replace dripping taps - You lose a huge amount of water and nerves a year.
58. Remember - in order to prepare hot water in a boiler room, it is necessary to burn natural gas, which is in short supply, and its combustion products destroy the environment.
59. Use insulation for hot water pipes throughout your home and insulate tanks.

Insulation

60. Insulate the attic with mineral wool - it is estimated that 25% of the heat from the house is lost through the roof!
61. Do not forget about the insulation of the attic hatch.
62. Use a spray sealant on hard-to-reach areas such as hot water inlet and outlet to protect them from cooling. Remember to use a mask.
63.33% of heat is lost through walls that are not properly insulated.
64. Use extruded polystyrene foam or its modern counterparts.
65. A comfortable and thick carpet will create a cozy atmosphere and minimize wastage through the floor.
66. The optimum insulation thickness for mineral wool is 250 mm. This is the real path to energy efficiency and comfort.
67. Eliminate drafts!
68. Consider replacing windows with modern ones that are energy efficient. Double glazing will reduce losses through window openings.
69. Install new windows flush with the outer wall of the house - this will eliminate the "cold bridges".

70. Use insulating tape for old windows - it's still cheap and effective.
71. When it's cold outside, close the curtains - this will help keep the warmth inside the house.
72. Keep windows and doors closed to keep warm inside.
73. Initiate the installation of a metering unit for heat energy consumption for each consumer - this will allow you to see the real result of your work on energy saving.
74. Consider upgrading your ventilation system to avoid opening windows for ventilation.
75. Recovering waste heat from the ventilation system and returning it to the room is a real way to save money.
76. The door to the outside of the house or apartment must be insulated from drafts and heat leaks.

Cold is also energy

77. Keeping the back of the refrigerator and freezer clean is an essential rule.
78. Do not overload the refrigerator - cold air must circulate, and clutter will prevent it.
79. Try to leave a quarter of the space in the refrigerator free - this will enable it to work efficiently.
80. Be sure to close the refrigerator and freezer doors tightly.
81. Install the refrigerator away from stoves, heaters and direct sunlight. The laws of physics cannot be fooled - the warm will warm the cold.
82. Replace your refrigerator with a more modern - energy efficient model of the "A" series.

83. Do not keep the door open longer than necessary. You lose cold, which means you will have to generate it again using electricity.
84. Put a thermometer in your refrigerator - the optimum temperature is 0-5 ° C.
85. Allow hot food to cool before placing it in the refrigerator. Hot food will make the refrigerator work harder.
86. Defrost your freezer regularly. Ice thicknesses greater than 6 mm contribute to inefficient freezer operation.
87. Be careful when throwing out old refrigerators - for sure you will be helped where you get a new one.

Economical cleanliness

88. Do not use the dishwasher until it is completely full. This will save you money.
89. Choose the size of all equipment adequate to the size of your home.
90. Try a cold wash. 85% of the energy in washing is spent on heating the water to the set temperature.
91. Do not forget to hand wash - this will save the quality of your clothes and your money.
92. Just try to wring or dry clothes outside the washing machine - this will significantly save energy.
93. An imperceptible difference of 10 ° C in the washing mode will allow you to really save money.
94. Use the "economical" mode when operating any home appliances.
95. Use a tumble dryer - you get the same result, but cheaper.
96. Radiators for heating, not drying clothes.
97. When buying new equipment, pay attention to the energy efficiency rating. Search with index "A".

To save electricity in an apartment, you need to learn how to use it rationally. At the same time, in addition to significantly saving money when paying for energy, you make a very important contribution to solving global environmental problems.

Every year, the cost of electricity and heating increases due to higher tariffs and an increase in the number of used electrical appliances.

Since the reserves of energy resources are very limited, the cost of electricity increases annually and, accordingly, our payments for electricity also increase.

Therefore, more and more people are starting to think about how to save electricity at home.

In addition, saving electricity will reduce the consumption of natural resources and reduce emissions of harmful substances into the atmosphere, which means that we can make a feasible contribution to the preservation of our rivers, lakes and forests.

By saving 100 watts of electricity, we can save 48 kg of coal, or 33 liters of oil, or 35 m3 of natural gas.

On average, a family of three living in an apartment of 50 m2 pays for energy resources about 59% of the total amount of utility bills, of which: 32% are heating and hot water supply, 15% - electricity, 12% - gas.

Tips on how to keep your home warm.

These tips are relevant for those who have heat meters or electric heaters.

1. Insulate door and window openings with a special insulation.

After all, the main heat leaks occur through windows and doors.

2. Install new energy efficient windows, preferably double glazed windows.

If you have a balcony or loggia, then glaze them too.

This is the most effective way to keep your home warm.

3. It is necessary to properly ventilate the room.

Ventilate when the heating is off!

Full ventilation for 2 minutes every 3-4 hours retains much more heat than permanent partial ventilation.

In winter, 2-3 minutes of complete ventilation is enough. In spring and autumn - up to 15 minutes.

4. Do not cover batteries with curtains and decorative plates and panels.

1. Check the integrity of the house wiring.

This will prevent electricity leakage (losses can be up to 30%)

and will reduce the risk of home appliance breakdown and short circuit.

2. Switch off electrical appliances that are in "standby" mode - TV, stereo system, DVD-player.

Most devices are active for several hours a day, and the rest of the time they are in standby mode, and a significant amount of energy is wasted.

3. Organize the right lighting.

but. Make the most of natural light

(use light curtains, light colors of walls and ceilings, wash windows more often, do not litter window sills.) This will make the room brighter.

b. Use the principle of area lighting - it is necessary to rationally use general lighting and local lighting.

General lighting is intended for general lighting of the room (chandelier).

Local lighting (lamps, sconces) allows you to illuminate dark corners of the room. The combination of local and general lighting (combined lighting) allows you to use the light more efficiently

Light only the part of the room that we need.

As a result of the combined lighting device for a room of 18-20 m2, up to 200 kW / h is saved.

4. Replace traditional incandescent bulbs with energy efficient ones.

They consume several times less electricity, and serve several times longer.

5. Turn off lighting and other electrical appliances that you do not need at the moment.

When leaving, turn off the light.

6. Wash lamps and shades more often.

How to save energy in the kitchen and when cooking

An electric stove is the most energy-intensive household appliance, it accounts for more than half of all electricity consumed. By following simple rules and techniques when preparing food, you can save a significant amount of electricity.

1. When cooking in a saucepan, turn on the hotplate at full power only until the water boils. As soon as the water boils, immediately switch the heating of the burner to the minimum position, while the energy consumption will sharply decrease, and the cooking time will not increase.

2. Make sure to close the pot tightly with the lid. When cooking in an open container, energy consumption increases by 2.5 times. Even if the lid is slightly open, it is tantamount to the fact that there is no lid at all. heat is lost with the leaving steam.

3. Use a pan with a base diameter that matches the size of the hotplate. The diameters of the pan bottoms must be greater than or equal to the diameters of the burners of the electric stoves on which they are placed.

4. Do not allow water to boil vigorously on the burner turned on at full power, because much less power is enough for boiling on a heated stove.

5.If you turn off the electric hob a little earlier before the end of cooking, you will save energy due to residual heat.

6. When cooking vegetables, use the minimum amount of water in pots.

7. Select the size of pots for the amount of food you need. If you need to cook a small amount of food, then it is better to do it in a small one. saucepan on the smallest burner.

8. The bottoms of pots and pans must be level and clean so that there is close contact with the burners. Cookware with a crooked bottom or carbon deposits requires 60% more electricity.

9. When buying cookware, choose pans and pans with a thick bottom and glass lids.

10. Use pressure cookers. They are very energy and time saving.

The cooking time in them is reduced by three times, and the power consumption is halved. This is achieved due to the tightness of the pressure cookers and a special cooking mode - the temperature inside the dishes reaches 120 degrees due to the excess steam pressure.

11. Stainless steel cookware with a thick polished bottom ensures good contact with the stove and saves energy. Enamelled, Teflon-coated aluminum cookware is not economical.

12. The condition of the hob burners is of great importance. If one or two coils are burnt in the hotplate or the hotplate is swollen from overheating, the energy consumption increases up to 50%. It needs to be changed urgently.

13. Use special electric heating devices (pans, pots, grills, coffee makers, etc.), in which the dishes are tastier and of higher quality, and much less electricity is spent. Use an electric kettle that saves energy by itself, turning off automatically when water boils in it.

Boil just enough water at a time.

14. Timely descaling inside electric kettles can significantly reduce energy consumption.

15. Use thermoses or potters to keep food and water warm for a long time.

16. Do not use the included burners of the electric stove to heat the room, it is uneconomical, ineffective and dangerous.

17. Use microwave ovens to heat up and cook food, they will save you time and energy.

What we usually do uneconomically:

¦ choose the wrong dishes - energy losses 10% -15%

¦ Do not close the dishes tightly when cooking. - losses 2% - 6%

¦ We use too much water - losses 5% - 9%

¦ We use dishes that are not the size of the burner - losses 5% -10%

¦ We do not use residual heat - losses 10% -15%

Not so long ago, the idea came to me to organize a competition of children's drawings on our blog about how they see energy. Yesterday I found out that I was ahead. On the corporate website of Bashkirenergo started children's drawing competition "Energy through the eyes of children"... Unfortunately, only corporate network users can view and vote for their favorite pictures. I downloaded some drawings from there and decided to post them on our blog.

Hopefully next year we will organize several similar contests ourselves.

Most of the drawings that I looked through contained the main "attributes of energy": chimneys, smoke itself, light bulbs, wires, sockets, batteries and other things that are usually associated with light and heat. There are many drawings with congratulations for the day of the power engineer, with poems and words of gratitude for the light and warmth.

The most active participants were schoolchildren from Buturlinovsky, Verkhnekhavsky, Nizhnedevitsky, Pavlovsky, Ertilsky districts.

The creativity of the children was assessed by the public relations specialists and labor protection engineers of Voronezhenergo. First of all, the experts paid attention to the originality of the ideas of the drawings.

The first place in the "junior" nomination (grades 1-4) was taken by Yulia Klimova, a second-grader from the Mosalsky school from the Kashirsky district. Julia portrayed harmful mice, for whom playing with an electrical outlet became an instructive lesson: the rodents were painfully electrocuted. For her work, the girl composed a poem, which ends with the words: "You, baby, must remember:" Be careful with the socket! "

The second place was taken by Artem Chernyshov, a 1st grade student of the Uglyanskaya Secondary School (Verkhnekhavsky District) with the drawing "Uncle Tok".

Third - second-grader of Buturlinovskaya secondary school Alina Lyashenko with the work "Don't play with electricity!"

In the category "Grades 5-8" the jury awarded the first place to Tatyana Sharapova, a sixth-grader of the Voronezh secondary school No. 18, with the drawing "Don't touch the bare wire!", Made in 3D format.

The second place was shared by Yulia Zatsepina from MKOU "Nizhnevedugskaya secondary school" (Semiluksky district) with a series of works "Electricity is not a toy!" and Irina Getmanova from the Poltava secondary school of the Bogucharsky district for the drawing "A charger left in an outlet can close!"

In third place - Katrin Nasoil from MCOU "Sokolovskaya Secondary School" (Ertilsky District) with the work "Electricity is not a toy!"

The children's drawing competition was held within the framework of an agreement on the prevention of electrical injuries, which Voronezhenergo concluded with the regional department of education, science and youth policy, said Ivan Kleimenov, Deputy General Director of IDGC of Center, JSC, Voronezhenergo Branch Director.

“I would like to thank the head of the department, Oleg Mosolov, for the organizational support of our action,” added Ivan Kleimenov.

According to him, Voronezhenergo, like other branches of IDGC of Center, pays special attention to the prevention of electrical injuries among children. Voronezh power engineers on an ongoing basis conduct open lessons on electrical safety in schools and children's health camps.
