PConline skills may not be known to everybody. Due to some of our bad habits, we have always been lurking around us with a "electric mouse." It steals our electricity bill all the time. It is the standby power consumption of electrical appliances. Standby power consumption refers to the energy consumed when the appliance is in a non-operating state but is powered up. So, how much impact does the "power mouse" of standby power consumption have on our monthly electricity bill? Please follow the home appliance detective J Jun to see what it is!
This time we use the power meter to test the standby power consumption of household appliances and calculate the corresponding electricity tariff according to the price standard of Guangzhou residents (0.61 yuan/kWh).

TV standby power consumption
First of all, we are testing a 55-inch flat-panel TV and putting it in a standby state. As can be seen from the picture, the measured standby power consumption of the TV set is 0.66W , which will generate 3.53 yuan in electricity bills in a year.

Then came out the small air-conditioner with the head “Power Consumption†title. After turning it off with a remote control, the standby power consumption was measured as 1.19W , and the electricity cost was 6.36 yuan a year .

Standby power consumption of washing machine
I do not know whether you have a small partner with this detective feel the same, in the winter when you can have a washing machine for your own laundry is really too happy, after all, no one likes to hit the cold water in the winter it! Well, dragging away, we immediately measured the standby power consumption of the washing machine. The results showed that the power consumption of the washing machine is 0.6W when it is in standby, and the electricity charge is 3.21 yuan for a year in standby.

Summary: It can be known from the test that large appliances still generate electricity when they are on standby. Although it seems that the amount of electricity generated is not too much, combined with such a large number of households across the country, the electricity bill is a huge sum of money.

Computer hosts
I believe many young partners are just shutting down the system for the computer, and will never unplug the plug, then let this detective to open up the mystery of computer standby power for everyone! Look at the picture!

It can be seen from the test pictures that the power plug of the computer main body is plugged into the socket, which will still generate 0.61W of power consumption. Over the course of a year, it will increase 3.26 yuan for the home.

TV box
Like television sets, we are also accustomed to using the remote control to turn off the TV box. But do not underestimate this small TV box, and its standby power consumption will be even higher than the big home appliances, do not believe you see!

After the actual measurement can be derived specific data, television box standby power consumption was 4.84W , is 4 times the water heater, washing machine 8 times! In this way, we can increase the electricity fee by 25.86 yuan .

Wifi power consumption
Including the detective, the home wireless router (wifi) will always let its power, but after testing, measured its power consumption is 1.94W , which means that it can increase 10.37 yuan a year. Therefore, the detective decided to unplug the WiFi plug before going to bed tonight.

Then the "unfortunate" was caught by the air purifier. We are considering how to punish it if its standby power consumption is too large. The data is coming out. Fortunately, the power consumption is also 0.3W , but it's a The year will also increase the electricity charge by 1.6 yuan .

Checked for so long, the detective also felt a little thirsty, came to the drinking fountains to drink before drinking, just to catch it and test the test. After turning on the heating function of the water dispenser, the power consumption instantly reached 511.3W.

After a while, the water dispenser is in standby state. From the reading of the power meter, it can be seen that the standby power consumption of the water dispenser is 0.34W . If it is not for many years, the electricity fee will increase by 1.82 yuan .

Summary: small appliances so small appearance, often gives people a "not too power-consuming" illusion, but absolutely did not think that looks the most lovely TV box, the standby power consumption can even as high as 4.84W! Therefore, for these small household appliances, we still unplug the plug when it is not in use.
After testing, the above household appliances do not pull plugs and wait for standby. A total of 61.62 yuan in electricity costs are generated in one year. However, if the households in the country are wasting 61.62 yuan, then the country's annual electricity bills are also very scary. Moreover, there are other electrical appliances that have not been tested one by one. Therefore, the electrical charges generated during the standby period of electrical appliances for one year are not all that much. Therefore, it is necessary to remove the plug when the appliance is not used!

Summary: There is a cloud in the old saying, "Do not treat evil as small and not as good as small." For the standby power consumption of household appliances, we cannot choose to ignore them because of the low electricity bills. Although electricity is a renewable energy source, the country will pay a certain price for every single kilowatt-hour of electricity produced. Therefore, when we go out or don’t use electric appliances, we may develop a good habit to unplug electric appliances, save energy and reduce emissions, and live a low-carbon life. We will start from now and start from ourselves.
