Energy conservation is a comprehensive concept that requires the whole society to act
“Energy saving? The lights in the home corridor and kitchen are energy-saving lamps. The air conditioner in our house was adjusted to 26 degrees Celsius in the summer...†Miss Zhang, who lives in Tianhe, counted her fingers. However, she did not realize that the living room in the living room is a crystal lamp that is both hot and energy-consuming. The ceiling lamp of the balcony is a light bulb, the air conditioner and the refrigerator belong to the old household appliances, and there is no energy-saving label...
Miss Zhang is just a common example. When Guangzhou promoted the concept of “energy savingâ€, many citizens did not realize that energy conservation is also a comprehensive concept –

Price, blocking the pace of energy-saving products?
It is an indisputable topic that energy-saving lamps do not save electricity in the end. A qualified energy-saving lamp saves 80% of electricity compared to incandescent lamps (ie, ordinary bulbs). Li Hong, a member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), has calculated an astonishing account. If a 10 watt energy-saving lamp is used to replace a 60-watt incandescent lamp with a similar brightness, and 1.2 million units are used nationwide for 4 hours a day, a three-gorge dam can be saved annually. The amount of electricity generated!
However, the “threshold†of the price of energy-saving lamps is also surprisingly high – “a 35-watt incandescent lamp costs only 1 yuan, but a 7-watt energy-saving lamp costs 18 yuan!†Lao Li calculated the account. "I spent 75 yuan to buy three energy-saving lamps. After using it for more than a year, they have been broken. I have calculated that the three energy-saving lamps have saved less than 70 yuan in electricity costs a year, not enough. Light money."
"Buy or not to buy, the price has the final say." Miss Huang, who bought air conditioners last summer, said. She originally wanted to buy an energy-saving hot and cold machine, but she was hesitant about the price of 3,568 yuan above. The energy efficiency ratio of energy-saving air conditioners in cooling was 3.95, which exceeded the national standard of 3.48, but Miss Huang counted. An account: a wall-mounted air conditioner of the same brand is only 2,220 yuan. In other words, energy-saving air conditioners will have to save money after 6-8 years.
Like energy-saving air conditioners, energy-saving lamps and solar water heaters all encounter similar flaws. An energy-saving lamp is at least 5 times more expensive than an incandescent lamp of the same size, and it takes 2 years to recover the cost; a solar water heater may take 6-10 years to enter the money-saving phase - at that time, it may already be used End of the year.
In an incomplete investigation, the reporter found that more than 80% of the people who used energy-saving lamps in the house; only 40% of the people who have energy-saving lamps in the whole house; and 60% of the people have old air conditioners and refrigerators. Energy-saving labels, and these people do not intend to replace these appliances in the near future for energy saving. Zhu Dongsheng, deputy dean of the School of Chemical Engineering and Energy, South China University of Technology, pointed out: "Replacing existing equipment and purchasing energy-saving equipment, when to recover costs has become the most concerned issue for many companies, not to mention ordinary consumers."

Waste, in casual habits?
Is there a waste of energy-saving products? No! Behind the public’s inadvertent “small actionsâ€, there is a source of waste. "I obviously haven't opened any home appliances. Why is the meter still turning?" I believe many people have asked this question. In many cases, it is not a problem with electricity meters. Instead, the family hides "electric mice" - standby appliances. Almost every day, you can "steal" a power!
Experts from the Guangzhou Power Supply Bureau told the reporter that the standby energy consumption refers to the power consumption when the electrical product is connected to the power supply and is in a waiting state, and the main function is not running. Simply put, the remote control is turned off without turning off the electrical switch or the power supply. The power consumption in the case. “Everyone can not underestimate this standby energy consumption,†the expert pointed out: “Every electrical device consumes about 10% of its power-on power in standby mode, about 5-10 watts, which is also counted. A lot of accounts."
The reporter took a bit of a bit. Take the TV as an example. A TV has a standby power consumption of 0.02 kWh. If it is calculated by waiting 18 hours a day, it will consume 0.36 kWh per day, and it will cost 80 yuan more for one year. According to the conservative estimate of 350 million units of TV sets nationwide, it is necessary to use 46 billion kWh of electricity, worth 28 billion yuan. According to the survey, the average standby energy consumption of each household is equivalent to the use of a 15-30 watt long-lighting lamp every day. The standby energy consumption accounts for about 10% of the household electricity consumption in China.
During the use of the air conditioner, the indoor unit filter should be cleaned at least once a month, and the refrigerator should have proper ventilation space around it. Keep away from heat sources, avoid direct sunlight, reduce the number of times the refrigerator is opened and open the door, and frequently remove dust from the filter bag of the vacuum cleaner. Remove the scale of the electric kettle heat pipe and turn down the volume of the TV set... Don't underestimate this small "action", and the savings will come.
