At the end of the year, household electricity consumption often soars like a spring tide, and with it, electricity bills soar like a tidal wave. Have you ever encountered that "electricity bill assassin"? In fact, these high electricity bills are closely related to the bad electricity habits we form in our daily life, but they are often ignored by us. According to the data, the power consumption of household appliances in standby mode in China is as high as 200 billion kWh a year, which is almost equivalent to the annual power output of the Three Gorges Hydropower Station. When people turn off household appliances, they often ignore the action of pulling the plug, and this small habit makes the monthly electricity bill an extra unnecessary expense. As for the following four electrical appliances, if you do not pull the plug after using it for a long time, then the annual household electricity bill may cost hundreds or even thousands of yuan more. They are like stealthy electricity bill thieves who steal our money quietly. So, for the sake of our wallets, let's work together to correct these bad electricity habits. 
In our daily life, the TV set-top box is a very inconspicuous existence. Its output power is usually between 15 and 20W, and only 5W in standby. It seems that a TV set-top box in standby mode does not consume much power. However, in reality, when the TV goes into standby, the TV set-top box is still working silently, undertaking the important task of signal conversion. That is, as long as the TV is in standby, the TV set-top box has already started working, but it just doesn't display the image on the screen. When most people turn off the TV, they will use the remote control to operate, often ignoring the existence of the TV set-top box. This way, if you don't cut off the power to the TV or unplug it, the TV will be in standby mode. Some TVs will still have their power on lights up. According to statistics, the output power of mainstream TVs in China is between 100 and 200W, and the output power of a few large TVs can even reach 300W. If you take into account the standby power consumption of the TV set-top box, then the average power consumption will increase by nearly 20 kWh per month. Although the frequency of TV use in domestic households is not very high at the moment, occasional neglect can lead to an increase in additional costs. For households that don't turn on the TV often, it is recommended to unplug the power plug directly and completely isolate the power supply. And for people who use TVs a lot, unnecessary power consumption can be reduced by turning off the standby mode. In addition, the energy consumption of a TV is closely related to the material and size of its screen. For those users who have high requirements for eye protection and energy consumption functions of their TV, it is recommended to choose an LCD screen instead of an OLED screen. After all, saving energy is both for our wallets and for our shared planet. Compared to the TV, the air conditioner is undoubtedly in the home"A large consumer of electricity"。Especially in the scorching heat and cold winter, it has almost become a soaring electricity bill"The culprit"。1.A 5 hp air conditioner consumes about 1 watt per hour on a hot summer day2 to 1between 5 degrees, while a 2 hp air conditioner can be as high as 25 degrees. This considerable electricity consumption, if you add in the tiered electricity price, many families may be surprised by the sudden high electricity bill at the end of the year. In order to save trouble, many people often do not unplug the power supply of the air conditioner, but who knows, this practice not only wastes electricity, but also may shorten the life of the air conditioner. What you may not know is that even if the remote control has turned off the air conditioner, if the power is not cut off, it will still be in standby mode, and the power consumption may only be a few watts to a dozen watts, but this number may gradually increase over time. Long-term downtime increases the risk of aging lines, electrical failures, and even fires. The air conditioner is at its peak when it is turned on, and when the indoor temperature stabilizes, its energy consumption is greatly reduced. Therefore, frequent switching is not a wise choice. Of course, air conditioning also has its own ways to save electricity, such as adjusting the air outlet angle, setting the right temperature, etc. However, the most effective way to save electricity is to clean the filter regularly, which not only improves the efficiency of the air supply, but also ensures the freshness of the indoor air. 
Advances in modern technology have provided us with more power-saving modes, such as timer or sleep mode. As long as we make good use of it, we can enjoy comfort while minimizing unnecessary electricity bills. In the busy center of the family, the kitchen is full of all kinds of "master" level appliances, refrigerators, range hoods, induction cookers, etc. However, among the many conspicuous big guys, some seemingly insignificant small household appliances may become hidden "electricity bill assassins". Microwave ovens and rice cookers, for example, have a power as low as 1 3W when they are in standby, but over time, the standby power consumption gradually accumulates, and we are often reluctant to unplug the power because we are afraid of trouble. The mainstream microwave ovens on the market are fully functional and proficient in defrosting, steaming or dehydrating. As soon as the knob is turned, the function is switched, and the standby power of the microwave oven also changes, quietly consuming electrical energy. The rice cooker does not automatically turn off the power after performing the specified task, and when the power is turned on, it quietly goes into keep warm mode, which continues to consume electricity. Although the power of small kitchen appliances is not large, the long standby time is enough to cause considerable power consumption, and may also affect its service life. When it comes to small appliances in the kitchen, the energy-saving strategy is not just about unplugging the power. We can also use the waste heat from the heating equipment or opt for more energy-efficient equipment. Domestic rice cookers are mostly level 2 or level 3 energy efficiency, while microwave ovens have class 1 energy efficiency products for us to choose from. Keep in mind, though, that less power and less power is better, it's the right fit. Clever use of these small appliances in the kitchen, such as cooking or baking food at regular intervals, can make them more effective. In the complex world of household appliances, electric water heaters are undoubtedly a controversial role. Whether it should be unplugged or not has become a hot topic. Zhengfang believes that there is no need to unplug the plug, because it can enjoy the convenience of bathing at any time, and the constant temperature mode designed by the manufacturer can also reduce the wear and tear of the equipment. The opposing side, however, advocates unplugging when explicitly not in use, which saves power and extends the life of the device. An electric water heater will undoubtedly consume a certain amount of electricity if it is powered on for a long time. Taking a 2 kilowatt electric water heater as an example, the power consumption in all-day insulation mode is about 2 kWh, which can reach 60 kWh per month. However, for those electric water heaters in standby mode all day, the daily power consumption can be maintained at 0Below 5 degrees. The consumption of a single day may not be much, but it is also a large expense when accumulated over a long period of time. In addition, the pricing model of electricity tariffs is changing, gradually shifting from tiered electricity prices to peak-to-valley electricity prices. This means that residents who do not unplug their electric water heaters for a long time may have to pay more extra costs. When choosing an electric water heater, it is recommended to try to choose a first-class energy efficiency product, and according to the life rules of family members, heat at the wrong time, avoid the water heater running around the clock, so as to control the water temperature. At the same time, regular cleaning of the internal water tank and heating rod of the water heater can also achieve efficient heating and reduce energy consumption. Today, when smart home has become a trend, we can use intelligent operation methods to get rid of the constraints of time, place and other conditions. By remotely controlling the heating time and temperature of the electric water heater, we can easily achieve the goal of reducing energy consumption. With the green and low-carbon lifestyle gradually gaining popularity, the energy consumption of household appliances has also received more and more attention. In fact, electricity bills should not be a muddy account, we should reject those "electricity bill assassins" and rationally plan our electricity consumption patterns. However, some casual electricity habits, like the "electricity bill assassins" lurking around us, can make us unknowingly waste a lot of electricity. 
Set-top boxes, air conditioner standby status, and various kitchen appliances are all representatives of these "electricity bill assassins". In addition to choosing electrical products with higher energy efficiency levels when purchasing, we also need to use electrical appliances reasonably and cultivate good electricity habits according to the design specifications in the manual. Becoming an "electricity bill assassin" is not the scariest thing, what is really frightening is that despite knowing that we can optimize our electricity consumption patterns, we still choose to compromise with the so-called "convenience". Therefore, we need to rationally plan our own electricity consumption mode, refuse the "electricity bill assassin", and make our lives more energy-efficient and environmentally friendly.
