With the rapid development of industry and people's excessive pursuit of material enjoyment, and with the uncontrolled development and utilization of natural resources, the original features of the earth, such as blue sky, fresh air, green fields, lush mountains, dense forests, clear rivers, clear lakes and blue oceans, have gradually traveled in our field of vision and become increasingly blurred, replaced by mountains of garbage, scarce resources and blue oceans.
I have known since I was a child that the resources of the earth are limited. As middle school students, we should cherish these priceless treasures more. Energy conservation and emission reduction are closely related to everyone's life. Why do many people say that going to Europe is like heaven? Why is the ecological environment in Europe so good? Because Europeans pay attention to ecological environment! Like us, they didn't pay attention to energy conservation and emission reduction during the rapid development, and they also suffered losses. Because of this, they learned a lesson and thought about environmental protection when doing everything. We should also establish such environmental awareness and form good habits as soon as possible.
In the school bathroom, water often flows everywhere: between classmates, in order to win whose QQ number is high, they often hang on the line all day long; At home, you can turn on a light, but it is bright. Neon lights lit up all night, chimneys smoking black smoke, flowing water, faucets that nobody cares about ... I can't help but think of the famous warning: If we don't cherish precious water resources, then the last drop of water on the earth is probably our tears!
But people still don't know their mistakes. Facing the earth that has been seriously polluted by over-exploitation and waste of energy, the only thing we can do is to save energy as much as possible! In fact, energy conservation can start from the small things around us. Some simple changes can reduce energy consumption. For example, office workers who are close to home can commute by bike without driving; Choose trains instead of planes for short trips; When it is not necessary to continue charging, unplug the charger from the socket; If you don't use the computer within an hour, turn off the host and monitor conveniently; Taking a shower instead of bathing every day can reduce carbon dioxide emissions by about 0. 1 ton per person throughout the year. ...
Saving energy is everyone's responsibility. Energy is not inexhaustible. I hope people can save energy and reduce emissions, save limited energy and protect the earth on which we live!
With the decrease of energy, people pay more attention to energy conservation. When I was still in primary school, I taught us the concept of energy conservation, just for us humans to live on the earth forever. In real life, people still don't know how to save energy, so that saving energy is just talk and can't be done completely. Often due to the lack of scientific common sense and "tips", resulting in unnecessary waste. Now I want to introduce home power saving.
Tips for saving electricity in rice cookers
There are two kinds of rice cookers on the market now: one is mechanical rice cookers, and the other is computer rice cookers. When using the mechanical rice cooker, cover the rice cooker with a towel, and be careful not to cover the air outlet, which can reduce the heat loss. When the rice soup is boiling, raise the button to dry the rice soup with the waste heat of the electric heating plate, then press the button and stew for 15 minutes. Be sure to unplug the power plug after using the rice cooker, otherwise the temperature in the rice cooker will automatically turn on when it drops below 70 degrees, which will not only consume electricity but also shorten the service life. Try to choose a high-power rice cooker, because cooking the same amount of rice, a 700-watt rice cooker is more time-saving than a 500-watt rice cooker. Generally, the power of computer rice cookers is about 800 watts, which is more energy-saving, but the price is a bit expensive, generally between 500 yuan and 800 yuan.
Tips for saving electricity on TV sets
Television can save energy in the following ways: First, control the contrast and brightness. Generally, the power consumption of the brightest and darkest color TVs can range from 30W to 50W. It is suggested to turn on the low wattage fluorescent lamp indoors and adjust the contrast and brightness of the TV set to the middle. The second is to control the volume, which is loud and consumes high power. The third way to save electricity is to watch DVD, preferably AV status. Because in the AV state, the signal is directly connected, which reduces the work of the TV tuner and naturally reduces the power consumption. Fourth, after watching TV, don't turn it off with the remote control, but turn off the power on the TV. Because after the remote control is turned off, the TV is still in standby state and still using electricity. Under normal circumstances, the standby time is 10 hour, which is equivalent to consuming half a kilowatt hour. Finally, add a dust cover to the TV set. This can prevent the TV from inhaling dust and increase power consumption.
Tips for saving electricity in air conditioning
1. Don't adjust the temperature of the air conditioner too low during use. Because the lower the temperature controlled by the air conditioner, the more power is consumed, so it is generally enough to reduce the indoor temperature by 6 to 7 degrees.
2. When the cooling at room temperature is set to 1 degree and the heating is set to 2 degrees, it can save more than 10%, but the human body can hardly notice this subtle difference.
3. Set high cold/high heat at startup to achieve the control purpose at the fastest speed; When the temperature is suitable, change it to medium-low wind to reduce energy consumption and noise.
4. The "ventilation" switch cannot be in the normally open state, otherwise it will increase the power consumption.
5. Less doors and windows can reduce the heat entering the outdoor, which is conducive to saving electricity.
6. In air-conditioned rooms, it is best to use thick curtains to reduce the loss of cold air.
7. The connecting pipe between indoor unit and outdoor unit should not exceed the recommended length, which can enhance the cooling effect.
8. When installing air conditioning, try to choose the dark side of the room to avoid direct sunlight. If there is no such condition, cover the air conditioner with a sunshade.
9. Regularly remove the dust on the outdoor heat sink and keep it clean. Too much dust on the radiator will greatly increase power consumption.
Tips for saving electricity in refrigerator
At present, the a++ class energy-saving refrigerators on the market are more energy-saving than ordinary refrigerators. Household energy-saving refrigerators generally consume 0.5? 0.8 kWh/day, while ordinary refrigerators generally consume 1? 1.5 kwh/day, which can save electricity by about half. In addition, in the process of using the refrigerator, we should pay attention to the following issues:
1. Don't put the refrigerated goods too close, leaving a gap to facilitate the circulation of cold air, so that the food can be cooled faster, reducing the number of compressor operations and saving electricity.
When you put fresh fruits and vegetables in the refrigerator, you must spread them out. If fruits and vegetables are piled together, it will cause external cooling and internal heating, which will consume more electricity.
3. For those big foods, you can pack them separately according to the amount that a family eats at one time, and only take out the amount that they eat at one time, instead of taking out a large piece of food from the refrigerator and putting it back after use. Repeated freezing not only wastes electricity, but also damages food.
4. Thawing methods include water flushing and natural thawing. A few hours before eating, you can take the food from the cold room (about 4 degrees) to the micro-freezing room (about/kloc-0 degrees), because the cold air of frozen food can help keep the temperature and reduce the operation of the compressor, thus achieving the purpose of saving electricity.
The layout of the refrigerator is also exquisite. Generally, we should pay attention to the following two issues:
1. When the refrigerator is placed, it is usually 5? 10 cm, the space above 10 cm and behind 10 cm can help the refrigerator to dissipate heat.
2. Don't put it with audio, TV, microwave oven and other electrical appliances, the heat generated by these electrical appliances will increase the power consumption of the refrigerator.
Energy saving is very important. Everyone should use these skills and should not stop doing these things because it is too much trouble. These things are of great benefit to everyone, it's just a little effort. Relevant departments should also increase capacity and publicize more. Let all mankind save energy, which is not always available! Work hard for our future generations!
Family energy conservation and environmental protection proposal
All families in each residential area:
Today, various policies and measures for environmental protection and energy conservation have become the development trend of civilized life that we are familiar with. However, do we really know them well? Have we really done it in our daily work and life? Is it that when you listen, you are still focused, and then you talk about happy words, so you don't concentrate when you do it? Energy conservation and environmental protection can not be achieved by shouting a few more slogans. It needs us to really improve from real life, start from everything around us and practice.
As every family, it plays an irreplaceable role in promoting social development and human progress, and is the main strength pillar of our social development. Therefore, we should improve the comprehensive quality of families, truly understand the practical significance and great role of energy conservation and environmental protection, organize each family member, hold them together firmly, start to understand and improve from all aspects of life, and implement the theme of energy conservation and environmental protection.
To advocate energy conservation and environmental protection, we must first reduce our understanding of where energy consumption is in daily life. Where is the pollution? Aiming at the main problems, improve the efficiency of energy saving and environmental protection. So which is more serious, family pollution or social pollution?
Recent research shows that the pollution caused by social industrial production only accounts for 4 1% of the pollution sources, while the pollution caused by modern families accounts for 59%. Compared with society, although family is only a cell of society, it is relatively serious in terms of pollution. Hundreds of toxic and harmful substances have been detected, and there are more than ten common ones. There is a set of statistical data that can further prove the harmfulness of household pollution: that is, a household produces 1.8 kg of garbage every day on average, throwing away five non-degradable plastic bags and two or three disposable lunch boxes; A family produces an average of 200 kilograms of wastewater every day because of washing hair, bathing and washing clothes. A family uses an average of 20 grams of chemicals every day. These pollutants and domestic wastewater flowing into rivers have been polluting our land, rivers and oceans.
According to media reports, in an indoor pollution survey of more than 2,000 household samples, the results show that more than 50% of households have indoor pollution, and the "culprit" is household appliances. What is even more worrying is that most of the families surveyed are not aware of the pollution problem of household appliances. At present, common pollution caused by household appliances includes bacterial pollution, radiation pollution and noise pollution, which are harmful to health and even endanger people's lives.
Seeing this set of data can't help but surprise us. All along, we have to point the finger at industrial production. As we all know, the biggest pollution source is ourselves, that is, every family. We usually don't pay attention to the consequences of environmental protection and energy saving. In the final analysis, what hurts the most is ourselves, our beautiful home, a clean and peaceful global village.
In terms of energy waste, families also account for a considerable proportion. Multiple TVs are turned on at the same time; Multiple computers are used at the same time; Don't cut off the power supply when the TV is not watching, and stay in standby state for a long time; Dozens of incandescent lamps with hundreds of watts are turned on at the same time; When the sensor of the voice control light is broken, the light will be on day and night; The water dispenser operates 24 hours a day; Some electric heating households don't blink when they use several kilowatts of electric stoves in winter; Turn on the tap and let it run for a few minutes. Hot water is coming out, just wash it slowly. ...
Bit by bit, it seems insignificant. But it's like this, and the energy waste in residential areas is quite prominent. Check our behavior, the common "unconscious waste", there is too much precious energy wasted in family life. Habit becomes nature, and many wasteful phenomena are cultivated by people for a long time, so there is not much consideration for saving household energy. However, in real life, it is actually very simple for us to get rid of those "habits" that are wasted at will, and we only need to lift a finger.
A good living and working environment is the condition for our human survival, and protecting the environment means protecting ourselves. Facing the reality of the deterioration of the earth's ecological environment and the shortage of resources, we should clearly realize that saving the earth, protecting the environment and saving energy are our common responsibilities. Family energy conservation and environmental protection are closely related to our lives and are easy to carry out. Doing a good job in family energy conservation and environmental protection not only saves resources, but also saves some expenses for families, killing two birds with one stone. Therefore, we launched an initiative:
First of all, start with household electricity, save every kilowatt hour and put an end to household appliance pollution.
Every family should strive to do the following:
A, replace the incandescent lamp with the fourth-generation LED green light source. Under the same brightness, its power consumption is only one tenth of that of incandescent lamp, but its life span is 50 times that of incandescent lamp.
B chlorine-free green household appliances and solar household appliances should be selected, such as solar generators, solar cookers, solar lamps, solar caps, solar flashlights, solar dryers, solar water heaters and floor heating systems. , not only energy saving and environmental protection, but also safe and convenient, which not only contributes to the national energy saving and environmental protection work, but also leads the new trend of family green life.
C. when purchasing air conditioners, consider the number of people who are most suitable for the room size. And the air conditioning temperature is set at 26-28℃ in summer.
D, the food stored in the refrigerator should not be too full, and there should be a gap of more than 100mm between the food in the refrigerator and between the food and the box wall. This can save energy by 20% every day than sticking to the wall.
E. The power consumption of the washing machine depends on the use time. Generally, it takes 3 ~ 4 minutes to wash synthetic fibers and wool fabrics, 6 ~ 8 minutes to wash cotton and linen fabrics, and 10 ~ 12 minutes to wash extremely dirty clothes.
F, don't turn on the TV very bright, and don't turn it too loud, because every time you increase the audio power of 1 watt, you will increase the electrical power consumption of 3 ~ 4 watts.
G, it is best to use an electric cooker to wash rice in advance and cook with warm water or hot water, which can save electricity by 30%.
H. Unplug the electric cooker immediately after use. When the temperature in the pot drops below 70 degrees Celsius, it will automatically be electrified intermittently, which not only consumes electricity, but also shortens the service life.
First, as long as a special energy-saving film is attached to the ordinary glass window, the indoor temperature will drop by at least 3℃. If the sun is stronger, the temperature difference will be further widened and the energy saving effect will be more obvious. According to reports, after adopting this energy-saving film, it can not only filter ultraviolet rays, but also save energy by 30%, with a service life of 20 years.
The second is to mobilize the whole family to comprehensively strengthen the ideological understanding of environmental protection and energy conservation.
First of all, parents should set an example for their children. Parents are the first teachers of the children. Because children are plastic and imitative, parents' words and deeds can affect children. Therefore, parents themselves must firmly establish the awareness of energy conservation and environmental protection, constantly improve their own quality, consciously achieve "environmental protection and energy conservation starts with me, starting from daily trivial matters", and penetrate energy conservation protection into all aspects of family life, setting an example for children in energy conservation and environmental protection. Secondly, pay attention to cultivating children's awareness of energy conservation and environmental protection. Parents can use weekends and holidays to take their children to some scenic spots to experience the beauty of the environment, and then take their children to some places with serious environmental pollution, so that children can witness the scene of garbage everywhere and sewage flowing. Through this comparison, children can feel the harm of environmental pollution. Finally, create a good energy-saving and environmental protection atmosphere for children. In daily life, parents should put environmental awareness into action, so that children can form good environmental habits in a subtle way. For example, when shopping, we should pay attention to choosing pollution-free green products; Starting from ourselves, do a good job in family hygiene and strive to create a clean living environment. In this way, through educating children, on the one hand, parents' awareness of energy conservation and environmental protection is strengthened, on the other hand, family expenses are really reduced, and they can also contribute to China's energy conservation and environmental protection work, which can be called "endless benefits".
Third, save every drop of water in life and try to reduce water pollution.
With the rapid economic growth and increasing population, it has become a very urgent task to alleviate the contradiction of insufficient resources, continuously improve the ecological environment and realize sustainable development. China is one of the world's 12 water-poor countries, and the fresh water resources are less than the world's per capita14, so water conservation is imminent.
According to statistics, according to a city with a permanent population of * * * 1 70,000 and more than 6 million households, if each household saves1kwh of electricity every month, the city can save 60 million kwh of electricity a year, which is equivalent to the power generation of a small power plant; If each household saves 1 ton of water every month, the city can save 60 million tons of water a year, which is equivalent to the total domestic water consumption of a city with a population of 800,000.
Always pay attention to saving water and preventing water pollution. We can start from the following aspects:
Promote the use of water-saving water valves and sanitary ware; Turn off the tap after using water, and don't let the water run empty; Check and maintain the faucet at any time to prevent dripping; Advocate multi-use of one water, so that water can be reused; Save water, use vegetable washing and rice washing water to flush toilets and water flowers; Phosphorus-free washing powder for washing clothes to reduce pollution; If the rinsed water is left to the next batch of laundry water, 30-40 liters of clean water can be saved at a time; Use detergent carefully, use soap as much as possible, don't pollute the water source, and always tell yourself that protecting the water source means protecting life!
Fourth, save every piece of paper, use recycled paper, save paper and protect forest resources.
At present, the main raw material for papermaking is wood. China paper industry needs to consume 654.38 million cubic meters of wood every year. When we use and consume a lot of paper, we are actually consuming forest resources. Now, on average, 4000 square kilometers of forests disappear every year on the earth. Forests can provide oxygen, absorb carbon dioxide, prevent climate change, conserve water, prevent wind and sand, and maintain ecological balance. In order to protect forests and reduce development, it is necessary to reduce the demand for wood. Recycling waste paper 1 ton can produce 800 kilograms of recycled paper, which can cut down less trees 17, save more than half of papermaking raw materials and reduce water pollution by 35%. Each piece of waste paper can be recycled at least twice. Therefore, we should advocate actively recycling waste paper, try to use recycled paper and double-sided paper, give full play to the advantages of e-government, vigorously promote paperless office, try to use electronic media to modify manuscripts, and strive to reduce paper consumption. Saving paper is the best measure to protect forest and environment.
Save oil per liter and reduce air pollution sources.
Reduce the dependence on motor vehicles, use bicycles or walk as much as possible for short-distance travel, and reduce the urban traffic burden; Reduce official vehicles and reduce private vehicles without affecting official business and ensuring safety; When it is really necessary to use official vehicles for emergency official activities, try to concentrate on taking them. Let's all become bus people and strive to be cyclists!
In addition, if you drive by yourself, you can master the following energy-saving and environmental protection skills: 1. A family car with a displacement of 1.6 liter can save 10 liter of gasoline every month if it slides in the parking space. 2. When starting, the clutch should not be loosened too fast, otherwise it will consume oil and easily stall; 3. When speeding up, lightly step on the accelerator; 4. When encountering a red light or braking the vehicle in front, don't slam on the brakes when rushing forward in high gear; 5. Pay attention to the water thermometer when the car is driving. The normal water temperature of the engine should be kept between 80 degrees Celsius and 90 degrees Celsius. Too high or insufficient will increase fuel consumption; 6. Always check the tire pressure to keep it in the best condition. Insufficient tire pressure will increase fuel consumption; 7. Don't change the tire size at will. Choosing a wider tire may make the car look more "sports car", but the wider the tire, the greater the wheel resistance and the more fuel consumption; 8. Use engine oil with the lowest viscosity. The lower the viscosity of engine oil, the more "labor-saving" the engine will be, and the more fuel-efficient it will be. 9. Don't warm up too much. Some car owners like to warm up before driving in the morning, but too long warm-up time will consume more fuel. You can let the car drive slowly for one or two kilometers to achieve the effect of preheating. 10, don't overspeed. For ordinary cars, 80 kilometers per hour is the most fuel-efficient speed. Statistics show that for every increase of 1 km per hour, the fuel consumption will increase by 0.5%. There are also some fuel-saving tips besides driving: insufficient tire pressure will increase fuel consumption; Try to use low viscosity engine oil, which can also save fuel; Turn on the air conditioner to ensure that the doors and windows are closed; Cleaning the dust screen regularly can save electricity by 30%.
Six, every family should save every grain, develop the good habit of thrift.
Who knows that every grain of Chinese food is hard? Cooking at home, you should do what you can. There is not much food, but the nutrition is balanced. Overeating or overeating will affect human health, and extravagance and waste should be put an end to. Parents should set an example for their children and cultivate their children's good habits of thrift from an early age.
Seven, use less disposable products to protect the earth's environment and ecological balance.
Modern life is full of many disposable items: disposable tableware, disposable tablecloths, disposable diapers, disposable toothbrushes, disposable cameras ... disposable items bring temporary convenience to people, but bring disasters to the ecological environment; They have accelerated the depletion of the earth's resources and brought environmental pollution to the earth. Using less disposable articles, using more durable articles and reusing articles should become a new social atmosphere and a new way of life. Reduce the waste of resources and energy, let us get rid of the temptation of "one-time consumption", we can use rechargeable batteries instead of ordinary batteries; Use handkerchiefs instead of paper towels; Use porcelain cups and glasses instead of paper cups; Use cloth bags instead of plastic bags; Use mechanical pencil instead of wooden pencils. If you often go out for dinner on business trips, you can bring a pair of chopsticks, a spoon, toothbrush, toothpaste, razor, shampoo, etc. to make your life environmentally friendly everywhere. When going out for a family trip, you should take all kinds of things with you to reduce the pollution and waste in disposable goods. At the same time, we should also convince friends around us to make energy conservation and environmental protection rooted in every family.
Eight, bring your own shopping bags to reduce white pollution.
In our life, plastic bags have become an indispensable thing. Whether in supermarkets, vegetable markets or street vendors, it seems natural to provide customers with plastic bags. In contrast, some consumers rely too much on plastic bags when shopping. Those disposable plastic bags not only cause huge waste of resources, but also increase the amount of garbage. Most consumers take supermarket plastic bags home as garbage bags, which will cause secondary pollution to the environment after being discarded. White pollution caused by plastic bags has become the enemy of urban environment.
The annual plastic waste in China exceeds 6,543,800 tons. If each plastic bag is spread out on an average of 0.6 square meters, then the area of plastic film discarded by each person every year is 240 square meters. Some plastic bags used by street vendors still have serious hygiene problems. Using less or not using plastic bags should be the first green life we advocate.
Household plastic bags are the focus of white pollution. Whether shopping in the supermarket or buying food in the street, plastic bags are essential. Therefore, every family should bring their own bamboo baskets when they go out to buy food, which is both beautiful and environmentally friendly.
Nine, pay attention to the small details of daily life.
1, use less coal stoves for cooking, use liquefied gas, and don't wait for the oil to smoke when cooking, so as to minimize air pollution.
2, all kinds of bonsai flowers on the balcony at home, often clean the room, often bask in the quilt, keep the air in the family environment fresh and pleasant.
3. Reduce noise pollution, and try to lower the volume when talking or playing a tape recorder.
4. Properly dispose of wastes, classify domestic garbage and reasonably discharge domestic water.
5. Protect wild animals and plants, do not eat wild animals, and protect ecological balance.
6. Advise family members, relatives and friends not to smoke and burn garbage at will, maintain family health and keep the environment clean.
7. Plastic bottles, waste paper, etc. After collection, it is sold to waste collection stations to reduce waste discharge.
8. Take good care of pets kept at home, prevent neighbors from resting and fecal pollution, and maintain a harmonious living community and environment.
Family, friends and national mobilization are the basis of building a resource-saving society. We long for a clean earth and a green, healthy and clean living space.
Let's actively respond to the content of the initiative, join hands, start from me, start from every family, start from bit by bit, protect the environment, save resources, be kind to the earth, let all of us consciously be propagandists and practitioners of environmental protection and energy conservation, and make our due contribution to building an economical society and realizing the green and sustainable development of China.
