When the electrical appliances at home are not in use, the electricity meter is running quietly. Many people do not know that this phenomenon is standby energy consumption. A recent interview by a reporter found that waste of standby energy consumption is relatively common in my country, and the public's awareness of this waste is seriously insufficient, and it is necessary to prevent standby energy consumption from becoming "hidden waste."
He consumes 10 kilowatt-hours of electricity in one month after leaving home.
The waste of energy in standby needs to be taken seriously.
Mr. Li’s work requires frequent business trips. Not long ago, he discovered that even if there is no one at home and all appliances are turned off, he will consume about 10 kilowatt-hours of electricity every month. , several inspections failed to find the cause, so I contacted the power department for a door-to-door inspection. It turned out that it was the central air conditioner at home that was causing trouble. Although Mr. Li would turn off the air conditioner every time he went out, the central air conditioner that was powered on and on standby would still consume a lot of standby energy.
is not running but still connected to the power supply. The resulting power consumption is called standby energy consumption . Unlike the effective energy consumption generated by electrical appliances during use, standby energy consumption is basically a waste of energy, and it is often a "hidden waste" that is not easily discovered.
reporters randomly visited more than ten households and found that waste of standby energy consumption is relatively common. Except for one or two elderly families, most of the TV sets and set-top boxes are turned off with the remote control, without turning off the switch or cutting off the power supply; common household appliances such as air conditioners, range hoods, and washing machines are turned off all year round. Power on standby state . The reporter also found that the electric water heaters and kitchen treasure in more than half of the households run 24 hours a day and will not be turned off even when people are not at home.
Yang Jiawei, account manager of Taiyuan Power Supply Company of State Grid Shanxi Electric Power Company, told reporters that according to his observation, many families do not notice the power consumption in standby mode. "For example, air conditioners are rarely used by most families in the north except in summer, but few people unplug and . Some people don't know that this will consume electricity, and some people know it, but they don't care."
During the interview, the reporter asked about their understanding of their own standby energy consumption. Most users said they were "not sure", "probably not much" or "never paid attention to it".

Standby energy consumption adds up to a lot
The total amount is huge
Interviewees pointed out that standby energy consumption is difficult to detect because it is a waste that "adds up to a lot". Yang Jiawei told reporters that taking a router with a standby power of 12W as an example, if calculated based on a daily standby time of 15 hours, the standby energy consumption of a router per day is 0.18 kilowatt-hours, which may not seem like much, but after a year it will It consumes 65.7 kWh of electricity. "The standby power consumption of in two or three years is enough to buy another router. "
In order to estimate the total standby energy consumption, the reporter conducted multiple interviews. Wang Fei, director of the Haier Air Industry Performance Research Institute, said that his team has measured the standby energy consumption of common household appliances. The five types of appliances in a household, including air conditioners, washing machines, TVs, microwave ovens, and rice cookers, were calculated. The standby power is 12W. To 15W, the standby energy consumption is about 3 to 5 days per kilowatt hour, that is, 0.2 to 0.33 kilowatt hour of electricity per day.
Zhang Min, a senior engineer at the Electric Power Research Institute of the State Grid Shanxi Electric Power Company made a simple calculation for reporters. includes 12 types of electrical appliances such as TVs, set-top boxes, and routers that are common in urban households. The daily standby energy consumption of a household is about 0.86 kilowatt-hours. If electric water heaters and kitchen appliances that are always running but not used are added, the daily energy consumption of a household can reach 1.52 kWh.
The reporter also invited a number of power account managers who have been serving households for many years to make estimates. The feedback results showed that the daily standby energy consumption of each household is between 0.3 kilowatt-hours and 1 kilowatt-hours of electricity.
Taken together, even if the daily standby energy consumption per household is 0.2 kilowatt-hours, a city with a population of 5 million (based on 1.9 million households) will consume nearly 139 million kilowatt-hours of electricity in standby throughout the year.

It is urgent to curb the unnecessary waste of standby energy consumption
The interviewed experts pointed out that under the current situation of tight power supply and demand, it is realistic and urgent to curb the waste of standby energy consumption. Reducing unnecessary waste of standby energy consumption can reduce coal consumption and carbon emissions. It can also reduce base load and alleviate load pressure during peak power consumption periods.
"The electricity cost caused by standby energy consumption is not large and is easily ignored by users." Zhang Min said, but must resolutely curb the waste of standby energy consumption that is meaningless, unnecessary, and does not produce value. .
Professor Han Xiaoqing, School of Electrical and Power Engineering, Taiyuan University of Technology, Han Xiaoqing suggested increasing the research, development, application and promotion of related energy-saving technologies. "Technological innovation is an important way to effectively reduce standby energy consumption. Scientific research institutes and enterprises should be encouraged to develop more low standby power consumption technologies and promote the application and promotion of related technologies."
Wang Fei said that my country's energy efficiency labeling system It has played a positive role in promoting enterprises to reduce the standby energy consumption of their products. However, as various new electrical products are emerging in an endless stream, should be included in the national compulsory access in a timely manner for those new products with high market maturity and large standby energy consumption. standards to guide its energy-saving development of .
Zhang Zhaoming, deputy chief engineer of the Living Appliances Testing Center of the China Household Electrical Appliances Research Institute, said that while the market regulatory authorities have stepped up supervision and spot checks on the energy-saving indicators promoted by enterprises, they can also give full play to the role of third-party testing agencies to measure standby power. The representative energy efficiency, energy conservation and other indicators are objectively evaluated, which plays a supervisory and motivational role.
Many interviewees also proposed that the public’s knowledge and awareness of energy conservation should be further strengthened, while also creating conditions for cultivating energy-saving habits and guiding the public to develop an energy-saving lifestyle.
