air conditioning
1. The instantaneous current of the air conditioner is large, and the frequent switching is quite power-consuming and easy to damage the compressor. Therefore, in order to prolong the service life of the air conditioner, it is necessary to avoid turning it on and off.
2. Turn off the air conditioner after a few hours, turn on the electric fan immediately, use this method at night, you don't need to turn on the air conditioner all night, save nearly 50% of electricity, and it is good for health. Place the fan under the air conditioner and use the wind power of the fan to improve the cooling effect. Set the air conditioner to work in dehumidification mode, which makes the room feel cooler and saves power than cooling mode, even if the room temperature is slightly higher.
washer
In the same long washing time, the motor starts more times when working in weak mode, that is, using strong gear actually saves power compared to weak gear, and can extend the life of the washing machine.
According to the speed of 1680 rpm (only applicable to turbine type) dehydration for 1 minute, the dehydration rate can reach 55%, generally dehydration does not exceed 3 minutes, and it is of little significance to extend the dehydration time.
microwave oven
To reduce the number of times you need to turn on and off the microwave oven when defrosting food, move the food from the freezer compartment to the freezer compartment in advance, thaw it slowly and then put it in the microwave oven.
Computer
When you don't use your computer for a short period of time, enable your computer's "sleep" mode to reduce energy consumption to less than 50%.
Turn off unused programs and peripheral devices such as speakers and printers, and let hard disks, floppy disks, and optical discs work at the same time. Reducing the brightness of the display can reduce power consumption.
Special attention should be paid to the complete discharge of the battery with a notebook. Try not to use external devices. Turn off devices and interfaces that are not in use and turn off screen savers.
Reasonably choose the shutdown mode, and use "standby" when you need to recover immediately.
Select "Sleep" for battery use, and do not choose "Shutdown" for a long time. When the battery is in use, under Windows XP; With SpeedStep technology, the CPU automatically reduces power consumption by up to 40%.
Gas
Cooking over high heat is shorter than low heat, which reduces heat loss. However, it is also advisable to let the fire go beyond the bottom of the pot to avoid wasting gas.
In summer, when the temperature is high, the water should not be covered before boiling, so that the water with a lower temperature than the air can be exchanged with the air, and then covered and boiled when the natural temperature rises to the air temperature, which can save gas.
Before boiling, wipe the water droplets outside the pot, try not to cook the food that can be cooked without steaming, and the food that is not easy to cook is boiled in a pressure cooker or smoke-free stainless steel pot, and heating the cooked food in the microwave oven and other methods also help to save gas.
Emission reduction
1. Choose a small displacement car
Compared with a 2.0-liter car, a car with a displacement of 1.3 liters can save 294 liters of fuel per year, and the corresponding emission reduction of 647 kg of carbon dioxide. If the exhaust volume of newly sold cars (about 3,828,900 units) in the country is reduced by an average of 0.1 liters every year, then 160 million liters of fuel can be saved and 354,000 tons of carbon dioxide can be reduced.
2. Replace plastic bags with cloth bags
Although the production of one less plastic bag can only save about 0.04 grams of standard coal, and the corresponding reduction of carbon dioxide emissions is 0.1 grams, due to the large daily use of plastic bags, if the country reduces the use of plastic bags by 10%, then it can save about 12,000 tons of standard coal and reduce carbon dioxide emissions by 31,000 tons per year.
3. Reduce the use of disposable chopsticks
If the country reduces the use of disposable chopsticks by 10%, it can be equivalent to reducing carbon dioxide emissions by about 103,000 tons per year.
4. Try to use the elevator as little as possible
At present, the annual power consumption of elevators in the country is about 30 billion kWh, and the elevator electricity consumption can be reduced by about 10% by changing the stairs on the lower floors and only partially opening multiple elevators during the rest time.
Doing a good job in energy conservation and emission reduction requires everyone to work together, and the specific methods are far more than these. Actively understanding the knowledge of environmental protection science is conducive to our better environmental protection activities.
Ecological and environmental protection science knowledge
1. What is indoor air pollution?
(1) Combustibles: toxic and harmful gases produced by coal stoves, gas stoves, and indoor smoking;
(2) Biological substances: bacteria multiplying in refrigerators and cooling systems, fungi breeding in air conditioning filters, dust mites growing in dust, and pollen brought in from indoor and outdoor areas;
(3) Chemical residues: benzene, formaldehyde released from various pesticides, household decoration or furniture plywood, etc.;
(4) Radioactive materials: Radon is released from cement, marble and other materials used in housing construction (according to surveys, 54% of the radioactive contamination currently known to mankind comes from radon);
(5) Asbestos: asbestos pipes made of shells, ventilation pipes made of asbestos corrugated paper, etc., cause indoor pollution due to wear and weathering.
The easiest way to control indoor air pollution is to ventilate, keep doors and windows open, keep the breeze open, and always be healthy.
2. Household noise - invisible pollution
Biologically speaking, all unpleasant sounds are noise. While people are more and more concerned about whether the outdoor environment is quiet and comfortable, they should also be concerned about whether the sound environment in the living room is environmentally friendly.
It is predicted that the noise generated by TVs and cassette recorders used in homes can reach 60-80 decibels, and washing machines are 42-70 decibels. According to clinical medical statistics, if you live in a noisy environment above 80 decibels, 50% of people will be deaf, and 85 decibels will make people feel upset and reduce work efficiency. Therefore, the volume and switching time of household appliances and other sound-generating appliances should be strictly controlled in the family room.
3. Be cautious with detergents and detergents
Detergents and detergents are mostly chemical products, and long-term improper use of detergents and detergents will manipulate the human nervous system and hinder people's intellectual development. Detergents and detergents remain on clothes, which can irritate skin allergies, and long-term use of high-concentration detergents and detergents will cause carcinogens to enter the human body from the skin and mouth, damaging health.
4. Why promote the use of phosphorus-free laundry detergent?
Laundry detergents sold in the market generally use sodium phosphate as a detergent. After washing, phosphorus-containing wastewater continues to flow into rivers and lakes, causing the rapid growth of cyanobacteria, causing "eutrophication" of fish and other aquatic animals in the water body due to lack of oxygen, until the water quality deteriorates or even stinks. High-phosphorus laundry detergent has direct irritation to the skin, which can cause burning pain, and washed clothes can sometimes cause itchy skin when worn on the body. As a result, high-phosphorus laundry detergents have become a source of irritation for common skin diseases such as contact dermatitis, baby diaper rash, and anteloderma plantar.
5. Don't use plastic bags for food
There are three kinds of plastic bags used by people now: one is that they can neither touch the skin nor put food, and can only be used to hold building materials; One is used for clothing; There is also a kind of food that can be barely used to hold food.
Most of these three plastic bags contain "toxins", such as polyvinyl chloride plastic is a toxic variety, although the raw materials are non-toxic, but stabilizers are added in the production process, and these additives are mainly lead stearate, which is toxic. These lead salts are very easy to precipitate, and once they enter the human body, they will cause accumulated lead poisoning, so plastic bags should never be used indiscriminately when loading food.
Popularization of environmental protection science knowledge
1. Green behavior of citizens in the 21st century
Get close to nature, take care of every green space, and actively participate in tree planting activities.
Change your eating Xi that is not good for the environment and use renewable materials.
Care about and actively participate in science and technology, so that it can become a driving force for improving the environmental situation.
Every activity is carried out with due consideration for its impact on the environment and precautions are taken.
2. Urban green space - the lungs of mankind
Urban green spaces have at least four major functions:
One is to purify the air. Absorb carbon dioxide, hydrogen fluoride, ammonia, chlorine and other toxic and harmful gases in the atmosphere, 100 square meters of grassland can absorb 1500 grams of carbon digasification for 10 hours, and release 100 grams of oxygen at the same time.
The second is to regulate the temperature of the atmosphere. 1 hectare of lawn evaporates about 6,300 kg of water per day, increasing the air temperature by 5-9%.
The third is vacuuming and sterilization. Larger green squares can reduce noise by 20-30 decibels.
3. What is indoor air pollution?
People spend more than 80% of their lives indoors, do you know what is the general air pollution?
(1) Combustibles: toxic and harmful gases produced by coal stoves, gas stoves, and indoor smoking;
(2) Biological substances: bacteria multiplying in refrigerators and cooling systems, fungi breeding in air conditioning filters, dust mites growing in dust, and pollen brought in from indoor and outdoor areas;
(3) Chemical residues: benzene, formaldehyde released from various pesticides, household decoration or furniture plywood, etc.;
(4) Radioactive materials: Radon is released from cement, marble and other materials used in housing construction (according to surveys, 54% of the radioactive contamination currently known to mankind comes from radon);
(5) Asbestos: asbestos pipes made of shells, ventilation pipes made of asbestos corrugated paper, etc., cause indoor pollution due to wear and weathering.

According to clinical medical statistics, if you live in a noisy environment above 80 decibels, 50% of people will be deaf, and 85 decibels will make people feel upset and reduce work efficiency. Therefore, the volume and switching time of household appliances and other sound-generating appliances should be strictly controlled in the family room.
5. Don't underestimate the harm of nitrogen oxides to the human body
As piped gas, natural gas, and liquefied petroleum gas replace honeycomb coal, nitrogen oxides have become a significant source of pollution in kitchens.
Nitrogen oxides are nitric oxide and nitric oxide, nitric oxide is colorless and odorless, and the binding ability with hemoglobin is stronger than carbon monoxide. Nitrogen dioxide is 4-5 times more toxic than nitric oxide. Although the amount of nitrogen oxides emitted from the kitchen is not enough to cause immediate death, it can continue to invade the human body and cause various diseases. Nitrogen oxides can directly reach the bronchioles and alveoli in the deep respiratory tract, irritating alveolar tissues, causing pulmonary edema, and in severe cases, lung cancer. For housewives, nitrogen oxides can also damage skin tissue, destroy delicate skin, and make people look aged. Therefore, it is recommended that housewives should turn on the range hood for a long time before and after cooking to minimize pollution in the kitchen.
6. Be cautious with detergents and detergents
Detergents and detergents are mostly chemical products, and long-term improper use of detergents and detergents will manipulate the human nervous system and hinder people's intellectual development. Detergents and detergents remain on clothes, which can irritate skin allergies, and long-term use of high-concentration detergents and detergents will cause carcinogens to enter the human body from the skin and mouth, damaging health.

These lead salts are very easy to precipitate, and once they enter the human body, they will cause accumulated lead poisoning, so plastic bags should never be used indiscriminately when loading food.
9. Several foods that should not be eaten more
Instant noodles: Instant noodles contain pigments and preservatives, which are harmful to the human body when eaten regularly.
MSG: Excessive intake of MSG will increase glutamate in the blood, causing short-term headaches, heartbeat, nausea and other symptoms, and will also adversely affect the life and death system of people.
Pickles: Pickles contain nitrite amines, which are often eaten and pose a carcinogenic hazard.
Fritters: In the production process of fried dough sticks, alum (potassium aluminum sulfate) must be added, aluminum is enriched in the kidneys and difficult to discharge, resulting in toxins to the brain and nerve cells, which can easily cause Alzheimer's disease.
Stinky tofu: Stinky tofu is easily contaminated by microorganisms during fermentation, and it also contains a large amount of volatile star salt ammonia and hydrogen sulfide, which deteriorates and decomposes proteins.
Songhua eggs: Songhua eggs use a certain amount of lead in the production process, and regular consumption will cause lead poisoning.
Spinach: Spinach contains oxalic acid, which will be excreted in the form of compounds in combination with zinc and calcium in food, causing a deficiency of zinc and calcium in the human body.
10. "Environmental protection" is not equal to "sanitation"
"Environmental protection" is environmental protection, and its main task is to protect and improve the production environment and ecological environment, prevent and control pollution and other public hazards, and focus on the prevention and control of water pollution, air pollution, noise pollution, solid waste pollution, etc. Its management body is the administrative department of environmental protection of the people's governments at all levels. "Sanitation" is environmental sanitation, and its main task is to eliminate the pollution of human life and its hazards, such as cleaning the streets, eliminating domestic garbage, human and animal feces, and eliminating mosquitoes, flies and rodents. Its management body is the urban construction or urban management department of the people's government at all levels.
