How to do household chores is an eternal theme for everyone. Now that the number of double-income households is increasing, improving the efficiency of housework is an urgent issue. Whether it’s difficult to take care of your child, or if you’re exhausted After work and come home, the housework won’t wait.

However, if you accumulate it, the rest will be difficult! At such times, home appliances are a reliable tool. Home appliances that save labor in household chores, such as dishwashers, cleaning robots, electric cookers, and food processors, have become very popular. Of course, there are many home appliances in this era, such as lighting fixtures, minibars, TVs, and air conditioners.

Home appliances make our lives easier and more prosperous in this way, but what we are concerned about here is the electricity bill.

This time, I would like to think about tips for saving electricity bills and energy-saving home appliances.

Home appliances that use a lot of utilities and electricity

First of all, what percentage of the household budget is utility bills?

According to the Ministry of Internal Affairs and Communications’ Annual Household Survey (Household Income and Expenditure) 2018, the average consumption expenditure of households with two or more people is about 191080 rs. Of this amount, the utility bill is 14644. rs. Electricity charges account for about half of that. (* 1)

▼ Breakdown of utility bills for households with two or more people (2018, monthly average)

  • Utility costs 14644 rs
  • [Breakdown]
  • Electricity charge 7400 rs (49%)
  • Water charges 2345 rs (23%)
  • Gas charge 2000 rs (22%)
  • Other utilities costs 870 rs (6%)

After all, the electricity bill is not stupid. Can’t you save a little more? To find out how to do this, let’s see which of the many home appliances consumes the most power.

Although it is old data as of 2009, according to this, only four of “refrigerator”, “lighting equipment”, “TV” and “air conditioner” account for more than 40% of the total. Therefore, it can be considered that if the power consumption of home appliances is reduced by centering on these four, it is possible to save energy effectively, and as a result, it is possible to save electricity bills.

However, how you use energy depends on your area, family structure, housing structure, lifestyle, etc., so it is important to know what your household uses a lot of energy.

How to save electricity

“Power saving” is one of the ways to save electricity bills. What is generally known is to reduce standby power consumption. This standby power consumption accounts for about 5.1% (* 2) of the amount of power consumed by a household in one year, which is equivalent to an electric charge of about 6,160 yen. This cannot be overlooked.

According to the materials of the Ministry of Economy, Trade, and Industry, as a method of saving power consumption during standby, “turn off the main power”, “unplug from the outlet in case of a crisis that is not used for a long time” “,” use the auto OFF function or display OFF function “3 Introducing one. (* 3)

However, depending on the type of home appliance, turning off the main power or unplugging the outlet may cause safety problems such as the detection function for water leaks and gas leaks and the antifreeze function not working. .. Also, it is possible that the settings will be invalid on Blu-ray recorders. In such a case, it is necessary to take some measures such as using the display of function without removing the plug.

Even if there is no problem, it is surprisingly troublesome to unplug each time. The auto-off function is convenient in such cases. This function, which automatically turns off the power after a certain period of inactivity, is familiar to PCs and smartphones. This function is also attached to TVs, so if you set it on home appliances that tend to be left on, you can save power naturally.

Recently, you can also use “tap with switch” to save power wisely. It’s a lot easier than unplugging, so I think many households use it.

Power saving method for each home appliance

From here, we will look at individual power-saving methods for “refrigerators,” “lighting fixtures,” “TVs,” and “air conditioners,” which generally consume a lot of power.

How to save electricity in the refrigerator

Refrigerators can save electricity bills by organizing the inside of the refrigerator. Check for things that you don’t need to put in the fridge, and try to put less of what you really need.

How to save electricity in lighting equipment

By switching from incandescent light bulbs to LED lamps and fluorescent lamps, we can expect a power-saving effect of 2,000 yen or more per year. (* 4) As you know, LED lamps have the disadvantage of high initial cost, but because they have a long life and low running costs, they have better cost performance than incandescent lamps in the long run. Is.

How to save power on TV

For TVs, adjusting the brightness is the most effective. You can save 730 yen a year just by adjusting it appropriately according to the brightness of the room. (* 5) It is also a good idea to clean the screen before making adjustments. If the screen is dirty, it will feel dark and maybe adjusted brighter than necessary. If the device has a brightness sensor, turn it on and it will adjust to the brightness of the room.

How to save electricity in the air conditioner

It is important to adjust the set temperature of the air conditioner. The basic principle is “high in summer and low in winter”, but the following efforts are especially effective.

In addition, “do not put anything in the outlet of the outdoor unit” and “use a fan well to circulate the air” are also useful for saving electricity.

If you buy a new energy-saving home appliance

If we can save energy on refrigerators, lighting fixtures, TVs, and air conditioners, which consume the most power among home appliances, there is a possibility that electricity bills can be saved significantly. If you plan to replace your home appliances, choosing one with Low Standby Power Consumption Will Be Very Effective. The Technological Innovations Of Manufacturers Are Remarkable, So It Can Be Considered That The Newer The Product, The More Energy-Saving It Is.

The Average Years Of Use Of These Home Appliances Are As Follows (* 6).

▼ Average years of use of home appliances

  • Air conditioner 13.8 years
  • Refrigerator 12.8 years
  • TV 9.5 years

Since the average service life is as long as around 10 years, it seems that there are many people in the cycle of “use until the end of its life and replace it if it breaks down.”

How to choose a refrigerator

From here, we will look at home appliances individually. First of all, there are three main points to choosing a refrigerator.

The first is “size”. Choose a volume that suits the number of family members and the amount of stock. It cannot be said that the volume of the refrigerator is large = the annual power consumption is also large. If you buy a small volume and overload it, you can consider a slightly larger size.

The second is the “freezer size”. Power consumption is affected by the size of the freezer. Choose a size that suits your lifestyle and reduces power consumption.

The third is to “choose products with high energy efficiency.” Recent products that have introduced inverter control and environmentally friendly vacuum heat-insulating materials are highly energy efficient.

How to choose a TV

The energy-saving of TVs has improved significantly in the last few years, and we can expect a significant effect by replacing them with new ones. Annual consumption increases as the screen size increases or the functionality become more complex.

There are three points to choose from: “size,” “function,” and “satisfaction.” Since TVs are not only for obtaining information but also for entertainment, the number of pixels, video display speed, and functions are also important factors. Considering the size of the room, frequently used functions, mainly who, where, in what scene, and how you want to enjoy it, choosing it in consideration of the annual power consumption will lead to high satisfaction.

How to choose an air conditioner

The point is to choose an air conditioner that suits the room conditions, such as the structure of the house and the floor plan. Let’s consult with a specialist at the store and make a selection. In addition, the guideline for replacement by purchase is the following three points.

  • It’s getting colder lately / heating is weak on cold mornings
  • I feel that my electricity bill has increased
  • I’ve been worried about the driving noise and turned up the volume of the TV
  • Useful information for replacement by purchase

Lastly, I would like to introduce two useful pieces of information when you buy a new one. First of all, do you know the following labels that you often see at retail stores?

Ministry of Economy, Trade and Industry Agency for Natural Resources and Energy “Energy Saving Performance Catalog 2019 Edition for Home Use” p.10 is processed and used after screenshots.

This is called the “Unified Energy Saving Label” and shows the energy-saving performance of home appliances. The larger the number of stars, the higher the energy saving.

This label also contains information such as “energy-saving standard achievement rate”, ” energy consumption efficiency “, and” annual electricity bill guideline “. When you buy a new product, check the energy-saving performance of the product with this label and use it as one of the factors to make a purchase decision.

The second information is the ” Energy Saving Performance Catalog Electronic Version ” , which is updated daily by the Agency for Natural Resources and Energy. If you search by entering the type of home appliances in this catalog, the following information will appear.

When purchasing a new home appliance, it is a good idea to read it before going to the store and also refer to the information on the manufacturer’s website to narrow down the candidates in advance.

in conclusion

Home appliances are tools that help our household chores and enrich our lives. Energy saving is an act that not only reduces household spending but also reduces carbon dioxide emissions, which cause global warming and protect the global environment.

Why don’t you enjoy your life-saving electricity by getting along well with home appliances and living a rich life while paying a little attention to the other side of the richness?
