Turn off the electric meter quietly -prevent standby energy from being "hidden waste"

The electrical appliances at home are not used, but the meter is quietly walking. Many people don't know yet. This phenomenon is standby energy consumption. Recently, the reporter's interview found that the phenomenon of waste energy consumption in my country is more common, and the public's knowledge of this waste must be seriously lacking, and the energy consumption of standby energy is required to prevent the energy consumption of "hidden waste."

Pay attention to the phenomenon of waste energy consumption in ten degrees from home in January

Mr. Li's work requires a business trip all year round. Soon, he found that even if there was no one at home and the electrical appliances, he would walk about ten degrees per month. He could not find the reason for several inspections, so he contacted the power department to check. It turned out that the central air conditioner in the home was "making monsters". Although Mr. Li turned off the air conditioner every time he went out, the central air conditioner of the power -standing standby would still generate a lot of standby energy consumption.

It is still connected to the power supply without running, and the power consumption is called standby energy consumption. Unlike the effective energy consumption generated in the use of electrical appliances, the standby energy consumption is basically a kind of energy waste, and it is often a "hidden waste" that is not easy to find.

The reporter visited more than ten families randomly and found that the waste of standby energy consumption was generally common. Except for one or two elderly families, most families' TVs and set -top boxes are only turned off with remote controls, and they do not turn off the switch or cut off the power. The common home appliances such as air conditioners, range hoods, and washing machines are all -in -year standby. The reporter also found that more than half of the family's electric water heater and kitchen treasure all run 24 hours, even when people are not at home, they will not turn off.

Yang Jiawei, the customer manager of Taiyuan Power Supply Company of the State Grid Shanxi Province, told reporters that according to his observations, many families will not notice the electricity consumption in the standby state. "For example, air conditioning, most of the families in the north are rarely used in addition to other summer times, but few people will pull out the market. Some people do not know that they will consume power. Some people know, but do not care."

During the interview, the reporter asked about their own standby energy consumption. Most users said that "not clear", "should not be much" or "never paid attention".

Stand -up energy consumption accumulation is small and large total amount is huge

Interviewees pointed out that the standby energy consumption is difficult to detect because it is a waste of "accumulating less". Yang Jiawei told reporters that taking a router with a standby power of 12W as an example, if calculated by 15 hours of standby time, then a router's one -day standby energy consumption is 0.18 degrees. It takes 65.7 degrees. "After two or three years of standby power consumption, it is enough to buy another router."

In order to estimate the total standby energy consumption, the reporter conducted interviews from various parties. Wang Fei, director of the Haier Air Industry Institute, said that his team had calculated the standby energy consumption of common home appliances to calculate the five types of electrical appliances of air conditioning, washing machine, television, microwave oven, and rice cooker of a family. The standby power was 12W By 15W, the standby energy consumption is about 3 to 5 days, that is, 0.2 degrees to 0.33 degrees per day.

Zhang Min, a senior engineer of the Electric Power Science Research Institute of State Grid Shanxi Province, made a simple calculation for reporters. Calculate the 12 kinds of electrical appliances such as TV, set -top boxes, and routers commonly used in urban families. A family's daily standby energy consumption is about 0.86 degrees. If the electric water heater and kitchen treasure that has been running but not used, the daily energy consumption of a family can reach 1.52 degrees of electricity daily.

The reporter also invited a number of electricity customer managers of many households to serve for an estimation. The feedback results showed that the daily standby energy consumption of each household was between 0.3 degrees and 1 degree.

In summary, even if it is calculated by 0.2 meters per day of standby energy per household, a city with a population of 5 million people (according to 1.9 million family households), the annual standby energy consumption is nearly 139 million kWh.

Urgently need to curb unnecessary standby energy consumption waste

Experts interviewed pointed out that under the current situation of power supply and demand, it is realistic and urgent to curb the waste of standby energy consumption. Reducing unnecessary standby energy consumption waste can reduce coal consumption, reduce carbon emissions, can also reduce basic load, alleviate the load pressure during the peak period of electricity consumption.

"The electricity costs brought by standby energy consumption are not much expensive, and it is easy to be ignored by users." Zhang Min said, but it is necessary to resolutely curb for waste of free, unnecessary, and valuable standing energy consumption.

Han Xiaoqing, a professor at the School of Electrical and Power Engineering of Taiyuan University of Technology, suggested that it will increase the research and 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 -standing power consumption technology and promote the application and promotion of related technologies."

Wang Fei said that my country's energy efficiency logo system has played a positive role in promoting the reducing product standing energy consumption, but the current new electrical products are emerging endlessly. For new products with high market maturity and large standby energy, they should be Incorporate the national compulsory access standards in a timely manner to guide its energy -saving development.

Zhang Zhaoming, deputy chief engineer of the China Household Electric Research Institute's Daily Electric Inspection Center, said that while the energy -saving indicators promoted by the enterprise, while the market regulatory authorities increased their supervision and random inspections, they could also give full play to the role of third -party testing institutions and represented by standby power.Energy efficiency, energy conservation and other indicators are objectively evaluated to supervise and incentive.Many interviewees have also proposed that they should further strengthen the knowledge of energy conservation and awareness of the masses. At the same time, they should also create conditions for cultivating energy -saving habits and guide the masses to develop energy -saving lifestyles.
