For example, multiple appliances are used at the same time, and the appliances are not unplugged after use. In addition, the waste on various dining tables is even more shocking. According to incomplete statistics, the waste on the dining table in China is as high as 60 billion yuan a year, and the consumption of related resources behind it is also quite amazing, such as the waste of water resources and the emission of carbon dioxide and sulfur dioxide.
According to statistics, in 2002, the emissions of sulfur dioxide and carbon dioxide in China ranked first and second in the world respectively, and the economic losses caused by air pollution accounted for 3% ~ 7% of GDP. From the perspective of environmental capacity, the allowable emission of sulfur dioxide in China is 6.5438+0.66 million tons, which has actually reached 27.65438+0.9 million tons, and the nitrogen oxides should be 6.5438+0.88 million tons, which has actually reached 6.5438+0.98 million tons. There has been a serious environmental "overdraft" phenomenon, and carbon dioxide has reached the highest value in nearly 420 thousand years. Nowadays, air pollution has greatly exceeded the carrying capacity of the atmospheric environment and has become a "cancer" accompanying our survival and economic development.
There is only one earth, and resources are extremely precious. The energy issue is not only an economic issue, but also a political and strategic issue. Many international disputes are closely related to this. In the next 15 years, China will still be in the stage of rapid development of industrialization and urbanization, and the rapid development of national economy will further increase the intensity of resource consumption. We are facing severe challenges such as population growth, prominent resource constraints and increased environmental pressure.
In order to speed up China's modernization, realize the grand goal of building a well-off society in an all-round way, and for the well-being of future generations and the sustainable development of human society, let's take action and make due contributions to building a beautiful home and speeding up the construction of an economical society.
Reduce the huge waste in catering.
Reduce the waste of livestock products
Livestock products such as pork are indispensable dishes on our table, but eating meat will also cause huge energy waste. If each person wastes less than 0.5 kg of pork every year, it can save about 0.28 kg of standard coal and reduce 0.7 kg of carbon dioxide. If China wastes less than 0.5 kg of pork per capita every year, it can save at least about 353,000 tons of standard coal and reduce 9 1. 1.00 million tons of carbon dioxide every year.
Drink one less bottle of beer every month in summer
The summer heat is unbearable, and beer has become an indispensable drink on people's table. Drinking beer on a hot day is not a bad thing, but some people drink too much when they are drunk, and when they are drunk, they are full of ugliness.
Drunk has several disadvantages: first, it hurts the body; Second, wasting resources and energy; Third, it causes pollution and waste. In the hot three months in summer, if everyone drinks less 1 bottle of wine every month on average, then 1 person can save about 0.23 kg of standard coal and reduce 0.6 kg of carbon dioxide. Nationally, it can save about 297,000 tons of standard coal and reduce 780,000 tons of carbon dioxide emissions every year.
Drink less than 0.5 Jin of white wine every year.
Liquor is an indispensable wine on the table, and it has also made the splendid wine culture of the Chinese nation. However, being drunk can easily lead to accidents. If 1 person drinks less than 0.5 kg of liquor in 1 year, about 0.4 kg of standard coal can be saved, and the corresponding carbon dioxide emission reduction is 1 kg. If the national 200 million "drinkers" drink less than 0.5 kg of liquor every year on average, they can save about 80,000 tons of standard coal and reduce 200,000 tons of carbon dioxide emissions every year.
Smoke one less cigarette every day.
Smoking not only affects health, but also causes energy consumption in cigarette production. If everyone smokes less 1 cigarette within 1 day, it can save about 0.14kg of standard coal every year, and correspondingly reduce 0.37kg of carbon dioxide. If all the 350 million smokers in China do this, about 50,000 tons of standard coal and 6,543.8+0.3 million tons of carbon dioxide can be saved every year.
Eat a moderate buffet.
When eating buffet, "eat more" and "eat less" are the direct causes of waste, and both should be corrected. In fact, eating less and eating more is the correct way to eat, which can avoid unnecessary waste.
Can't eat. Pack up and leave
When eating out, you should order food in moderation and pack the food you can't finish home to avoid unnecessary waste.
Avoid using disposable chopsticks and other tableware.
Although China has a vast territory and a large population, the national forestry coverage area is quite low, and the widespread use of disposable chopsticks will cause a large area of trees to be cut down. If the use of disposable chopsticks in China is reduced by 10%, it can be equivalent to reducing carbon dioxide emissions by about103,000 tons every year.
In addition, the use of plastic products such as snack boxes, straws and disposable spoons should be minimized to avoid environmental pollution caused by plastic products that are difficult to degrade.
Methods of saving water in kitchen
Intermittent flushing water-saving method
If you want to effectively save water resources, then you must control the flow of the faucet, and change the uninterrupted flushing into intermittent flushing in the process of using the faucet, which can effectively save water.
Wash vegetables in order
When washing vegetables, don't wash them directly under the tap, try to put them in a container filled with water, and adjust the washing order. Peeled vegetables should be peeled and mud removed before cleaning. The general order of washing vegetables is: first wash leafy vegetables, fruit vegetables, and then wash root vegetables.
Wash vegetables in a basin with water.
Instead of washing directly under the tap, each household can save about 1.64 tons of water every year, and at the same time reduce the same amount of sewage discharge, and correspondingly reduce the carbon dioxide emission by 0.74 kg. If 65.438+0.8 billion urban households in China do this, it will save 5.65438+0 million tons of standard coal and reduce 6.5438+0.34 million tons of carbon dioxide emissions every year.
Install the dual-purpose water nozzle for cleaning.
The washing water faucet can be directly installed on the faucet in the family kitchen. If necessary, pull the small handle to change the water flow into a spray state, which can expand the washing area by four times, prevent splashing and accelerate the washing speed. Pull your hand back and the water will be concentrated. This can save 1/4 water consumption. Usually rice is washed once.
Rice contains essential nutrients for human body, but the nutrients on the surface of rice grains are usually lost with water when washing rice. Too many times of rice washing will not only lead to nutrient loss but also waste water. Generally, rice can be washed once.
Clever use of rice washing water
The remaining rice washing water can be used to wash other fruits and vegetables, water flowers or wash dishes. This practice can not only save water, but also not pollute the water quality.
Soak dried vegetables in rice.
Soaking dried vegetables such as kelp, carrots and cuttlefish with rice is not only easy to soak and wash, but also easy to cook and cook, saving water and energy.
Wash dishes with old corn flour
Washing dishes with old corn flour not only absorbs oil without hurting hands, but also is easy to wash, effectively reducing the amount of washing water, thus achieving the purpose of saving water.
Methods of decontamination and water saving in kitchen
Skillfully use noodle soup to remove oil stains.
Noodle soup and jiaozi soup have a certain degreasing effect and can be used for washing dishes and chopsticks. The method can reduce the accumulation of detergent in human body and the pollution to water quality.
A good way to remove oil stains from the ground.
Vinegar can effectively remove oil stains. As long as the right amount of vinegar is dripped on the mop, the oil stains on the floor can be easily removed. Usually, it is difficult to remove oil stains from cement floor. You can take some plant ash the night before, mix it with vinegar, sprinkle it on the floor, and then rinse it with clear water the next day, so that the cement floor can be brand-new and the amount of detergent and water can be effectively reduced.
Degreasing of stainless steel kitchenware
If you want to quickly treat the oil stains on the surface of stainless steel kitchenware, just sprinkle a little flour on the oil stains and then wipe them with waste soft plastic or cloth, which can effectively remove the oil stains, make them as bright as new, and reduce the amount of detergent and water.
Cleverly remove oil stains from the cooker.
Sticky rice soup can be spread on the oil pan. After the rice soup is crusted and dried, the oil can be scraped off gently with iron sheets. If you use thinner rice soup and noodle soup to clean the oil directly, the effect is also good.
Energy-saving method of kitchen cooker
Adjust the air inlet
If the cooker wants to save energy, we must first adjust the size of the air inlet to make the gas burn fully. The way to judge its full combustion is that the flame is clear and active, and it is pure blue; The height of the stove rack should make the outer flame of the flame fully contact with the bottom of the pot; Large-diameter pot is more fuel-efficient than pointed-bottom pot; It is best to use several holes of a furnace at the same time.
Energy-saving ring using furnace plate
If you put an energy-saving ring on the furnace plate, it is convenient, cheap and durable.
Avoid gas furnace leakage.
The gas stove has been used for a long time, and the fire outlet is easily blocked by dust, which not only affects the "firepower", but also causes air leakage, so the dust on the fire outlet should be thoroughly removed in time every once in a while.
Tighten the valve of the gas stove.
After boiling liquefied gas or gas, tighten the cylinder or pipeline valve first, and then turn off the gas stove. This can not only avoid the danger of gas leakage, but also reduce unnecessary waste.
Liquefied gas should be equipped with energy-saving hood and high-pressure valve.
If liquefied gas is used at home, an energy-saving cover and a high-pressure valve should be installed. After installing energy-saving equipment, the original 15 kg liquefied gas can be used for about 40 days, and it has been used for nearly two months, and the gas inside is particularly clean.
Energy-saving method using range hood
Reasonable selection of range hood
Ultra-thin range hood has general effect and is not easy to clean. It is recommended to choose a model with appropriate power, strong suction, low noise and simple cleaning.
Do not use the range hood as an exhaust fan.
Don't use the range hood as a ventilation device, only start the range hood when there is lampblack, which can prolong the service life of the range hood.
Try to avoid the range hood idling.
When cooking in the kitchen, it is necessary to reasonably arrange the use time of the range hood to avoid idling for a long time and wasting electricity. If the idling time of each range hood is reduced by 10 minute per day, 1 year can save electricity by 12.2 degrees, and the carbon dioxide emission will be correspondingly reduced by 1 1.7 kg. If this measure is taken for 80 million range hoods in China, 980 million kWh of electricity will be saved and 936,000 tons of carbon dioxide will be reduced every year.
