Low-carbon life is to reduce energy consumption in daily life, thus reducing carbon, especially carbon dioxide emissions. Simply understood, low-carbon life is to return to nature and carry out activities between man and nature, mainly changing the details of life from three aspects: saving electricity and saving solar terms and recycling. If environmental protection concepts such as protecting the environment, protecting animals and saving energy have become the code of conduct, then low-carbon life is a green lifestyle that we urgently need to establish.

The United Nations Climate Change Conference held on February 7th, 65438 made the word "low carbon" the focus. For many citizens, the "low-carbon economy" and "low-carbon industry" that have been widely concerned recently seem to make everyone feel distant and unfamiliar, but in fact, everyone's life is closely related to carbon emissions, and everyone is affecting the changes in the global environment. Recently, the "low-carbon life" model has quietly emerged in this city. Tianjin, as the first pilot city of "National Low Carbon Action Plan", 330 families participated in the household carbon emission tracking survey; Among the young people in Jincheng, it has become a fashion to calculate carbon emissions and be a "low-carbon expert".

White-collar workers with cars emit nearly 10 tons of carbon every year.

Recently, an online "personal carbon footprint" calculator has become popular among many young people in this city. As long as you input the amount of food, clothing, housing and transportation on this calculator, you can calculate the amount of carbon dioxide you emit every year. The reporter saw on the calculator's web page that the number of clothes purchased, the number of washing powder used, the number of smoking and drinking, and the number of flights and trains have all become the calculation contents.

The shocking figures have made some office workers in this city consciously start "low-carbon action", and low-carbon life has gradually become popular among young people. ChristianRandPhillips, 25, is one of them. ChristianRandPhillips, who works in a foreign company, is an out-and-out "low-carbon family". She told reporters that since she volunteered to be an environmental volunteer, she has used the online "carbon emission calculator" to calculate her "low carbon life" every day. "Take the stairs as far as possible, turn on the air conditioner less at work or at home, replace the light bulbs at home with energy-saving ones, try to take the subway and bus when not driving, and use paper on both sides when printing ... In fact, a' low-carbon' life is to make every detail in your life as economical and green as possible."

Low-carbon life refers to reducing energy consumption in daily life as much as possible, thus reducing carbon dioxide emissions. Low-carbon life is an attitude, not an ability, for ordinary people. We should actively advocate and practice a low-carbon life, pay attention to saving electricity, oil and solar terms, and start from scratch. In addition to planting trees, some people buy goods with short transportation mileage. Some people insist on climbing stairs in various ways, some of which are interesting and some of which are unavoidable. But people who care about global warming have actually brought carbon dioxide reduction into their lives.

The ideal form of low carbon economy is to fully develop sunshine economy, wind energy economy, hydrogen energy economy and biomass energy economy. But at present, the cost of solar power generation is 5- 10 times that of coal-fired hydropower, and the price of wind power generation in some areas is higher than that of coal-fired hydropower; As a secondary energy, hydrogen energy is far from the commercialization goal of extracting clean energy such as wind energy and solar energy. Developing biofuels at the expense of consuming a large number of grain and oil crops has caused the prices of grain, meat and edible oil to rise to some extent. Globally, it is estimated that solar power generation will only reach 65,438+00% of the world's electricity supply by 2030, and the world's proven oil, natural gas and coal reserves will be exhausted in the next 40 years, 60 years and 65,438+000 years respectively. Therefore, one of the important meanings of "low-carbon economy" and "low-carbon life" is to save fossil energy consumption and provide time guarantee for the popularization and utilization of new energy in the next few decades when "carbon fuel civilization era" is in transition to "solar energy civilization era" (wind energy and biomass energy are both conversion forms of solar energy). Especially from the energy structure of China, low carbon means energy saving, and low carbon economy is based on low energy consumption and low pollution.

"Give up hobbies! The theme of Low-carbon Economy Environment Day reminds people that "low-carbon economy" not only means that the manufacturing industry should speed up the elimination of backward production capacity with high energy consumption and high pollution, but also means guiding the public to reflect on which habitual consumption patterns and lifestyles are bad habits of wasting energy and increasing pollution, so as to fully tap the great potential of energy conservation and emission reduction in the service industry and consumers' lives.

One of the important ways to turn to low-carbon economy and low-carbon lifestyle is to get rid of the hobby of "convenient consumption" at the expense of high energy consumption. Convenience is a universal value in modern commercial marketing and consumer life. Many convenient consumption methods are inadvertently wasting huge energy. For example, according to the estimation of refrigeration technology experts, 70% of the electricity consumption of supermarkets is used for freezers, while the electricity consumption of open freezers is 20% higher than that of glass door freezers. Based on this calculation, an open freezer in a medium-sized supermarket consumes about 4% more than a year. 80,000 kWh, equivalent to consuming about 19 tons of standard coal, emitting about 48 tons of carbon dioxide and consuming about190,000 liters of clean water. There are about 800 large and medium-sized supermarkets and 6000 supermarket convenience stores in Shanghai. If glass door freezers are widely used in large and medium-sized supermarkets, customers can save about 452 10000 kWh a year, which is equivalent to saving about 1. 80,000 tons of standard coal, reducing emissions by about 4. Fifty thousand tons of carbon dioxide.

In China, the annual per capita CO2 emission is 2.7 tons, but even if a white-collar worker in a city only has 40 square meters of living space, driving a car 1.6L after work and flying 12 times a year, the carbon emission will be 26 1 1 ton. From this point of view, energy conservation and emission reduction is imperative.

If environmental protection concepts such as protecting the environment, protecting animals and saving energy have become the code of conduct, then low-carbon life is a green lifestyle that we urgently need to establish.

Although "low-carbon life" is a new concept, it raises an old problem of sustainable development in the world, which reflects the concern for the future caused by climate change, and the world is increasingly aware of this problem. Climate problems such as global warming make human beings have to consider the current ecological environment. Humans realize that excessive carbon emissions in the process of production and consumption are one of the important factors that cause climate problems, so to reduce carbon emissions, some consumption and production activities should be optimized and restrained accordingly. Although some scholars still have different views on the causes of climate change, the concept of "low-carbon life" is at least in line with the prudent principle of "preparing for a rainy day" and the psychology and ideal of pursuing perfection, so it is better to believe what it has than not, and the concept of "low-carbon life" is gradually accepted by all countries in the world.

The emergence of a low-carbon life not only tells people what you can do to reduce carbon, but also tells people what you can do. When this lifestyle gradually rises, people begin to care, have I done anything to reduce carbon today? In Badaling, Beijing, a carbon sink forest farm has begun to take shape. If you want to offset your carbon emissions, you can come here to buy carbon sinks or plant trees. Forestry carbon sinks absorb and fix carbon dioxide in the atmosphere and release oxygen through afforestation, forest management and vegetation restoration, thus reducing carbon dioxide in the air. The idea of buying carbon sinks is more popular than driving less and turning on the air conditioner. At present, the main measures to slow down climate warming are to reduce emissions and increase foreign exchange. Compared with emission reduction measures, forestry carbon sequestration measures have become an important means to slow down climate warming because of their low cost, multiple benefits and operability.

What kind of people can be regarded as "low carbon people" and what does "low carbon" mean? Simply put, "low carbon" is a living habit, and saving all kinds of resources around you is a natural habit. As long as you are willing to discipline yourself and improve your living habits, you can join in. Of course, low carbon doesn't mean that you should be frugal and give up some enjoyment of life. As long as we can save more and not waste, we can also live a comfortable "low-carbon life". Since the Copenhagen Climate Change Summit opened on February 7th, 65438, it has been given various heavyweight titles such as "the most important conference in history" and "the conference that changed the fate of the earth". This conference attempts to establish a global framework for greenhouse gas emissions, and it also makes many people begin to deeply reflect on the current production and lifestyle of human beings.

I used to turn on the light all night, and the water dripped from night till tomorrow morning, and the refrigerator was full of sundries. In this way, water and electricity are wasted. ...

Now, I heard that the city is promoting a low-carbon life, and I gradually understand. I started a "low carbon life".

First of all, a low-carbon lifestyle is to pay attention to energy saving and consumption reduction in the details of life. Except that you must turn on the light when you do your homework, everything else depends on the light outside the window. Because our living room is large, the lights outside the window can clearly see everything in the room. When eating, it's really like "candlelight dinner". This is really "natural light!"

As long as it is washed, I will screw the tap tightly to prevent the water from "running out", so I will feel at ease. But I'm worried about whether mom and dad will do well. Every time I see my parents go into the bathroom to wash their hands and turn off the tap naturally, I am very happy. I hope that "low-carbon families" will do better.

There is a mess in the refrigerator, and my mother says it's a waste of electricity. I had a brainwave and came up with a coup: so I picked up the cardboard piled up before and made it into boxes of different sizes, and put various classification marks on it. Then, I sorted it according to the classification. After a while, the refrigerator became clean and tidy, brand-new, and I saw the neat things at a glance. In this way, it not only helps us, but also saves electricity.

It turns out that even a small cell phone battery will emit terrible carbon dioxide when it is plugged into the socket when the appliance is on. As long as you are charging, you should take out the battery immediately. I thought that carbon dioxide would only be emitted from automobile exhaust and coal burning, but I didn't expect that there were weak "carbon" everywhere in our lives that were infringing on our lives and the earth.

Whenever I see my mother trying to throw away that bucket of washing powder, I will come forward to stop it. I will make it into a small trash can, some like dolls, with a pink face, so cute! Some are like small animals, lifelike, really like a beautiful "landscape"!

As night falls, after dinner, neon lights on the roadside add a luster to the night. Dad always turns off all the lights in the house, leaving only an opaque darkness. Then, he lay in the window and sang a song: "The moon represents my heart …" It was really messy.

Growing flowers is my mother's hobby. The orchids and ivy at home are full of green all year round. Every hot summer, my mother always brings flowers into the house. Everyone looks at the green and allows them to suck. Suddenly I feel a little cold in my heart and the air is so beautiful. It's killing two birds with one stone!

Such a good home environment is full of creative fun.

Trying "low-carbon life" and "low-carbon life" is to reduce the energy consumed in daily life, thereby reducing carbon, especially carbon dioxide emissions. Low-carbon life, for ordinary people, is an attitude, not an ability. We should actively advocate and practice a "low carbon" life, pay attention to saving electricity, oil and solar terms, and start from scratch.

It is imperative to save energy and reduce emissions.

If environmental protection concepts such as protecting the environment, protecting animals and saving energy have become the code of conduct, then low-carbon life is a green lifestyle that we urgently need to establish. Simple understanding, low-carbon life is to return to nature to carry out human and natural activities, mainly from the three aspects of saving electricity and saving solar terms and recycling to change the details of life, including the following good living habits:

refrigerator

■ There should be a gap of about 10 mm between foods and between foods and refrigerators.

■ Using several plastic boxes to hold water, making ice cubes in the freezer and putting them in the freezer can prolong the downtime and reduce the start-up time.

The instantaneous current of air conditioner is large, and frequent switching consumes considerable power, which is easy to damage the compressor.

■ Put the fan under the air conditioner and use the wind power of the fan to improve the cooling effect.

■ Turn off the air conditioner after a few hours and turn on the electric fan immediately. Using this method at night, you don't need to turn on the air conditioner all night, saving nearly 50% electricity.

■ Setting the air conditioner to dehumidification mode can make people feel cool even if the room temperature is slightly higher, which saves more electricity than refrigeration mode.

For the same long washing time, the motor starts more times when it works in weak gear, that is to say, using strong gear actually saves electricity than weak gear and can prolong the life of washing machine.

■ According to the rotation speed 1680 rpm (only applicable to turbine type) and dehydration time 1 min, the dehydration rate can reach 55%. Generally, dehydration does not exceed 3 minutes. Prolonging dehydration time is of little significance.

■ Dry food is mixed with water evenly, covered or wrapped with polypropylene plastic wrap before heating, or heated with heat-resistant glassware with cover.

■ The food heated or cooked at a time should not exceed 0.5 kg, and it is best to cut it into small pieces. When the quantity is large, it should be heated in different periods and stirred in the middle.

■ Use "high firepower" as much as possible.

■ In order to reduce the switching frequency of the microwave oven when thawing food, food can be moved from the freezer to the freezer in advance and slowly thawed, so that the "cold energy" in frozen food can be fully utilized.

computer

■ When the computer is not used for a short time, turning on the "sleep" mode of the computer can reduce the energy consumption to below 50%; Turn off unused programs and peripherals, such as speakers and printers; Do not let the hard disk, floppy disk and CD work at the same time; Reduce the brightness of the display appropriately.

■ Pay special attention to the use of notebook computers: completely discharge the battery; Try not to use external equipment; Shut down temporarily unused equipment and interfaces; Close the screen saver; Reasonable shutdown mode: use "standby" when immediate recovery is needed, "sleep" when battery is used, and "shutdown" is not needed for a long time; When using the battery, under WindowsXP, the CPU automatically reduces the frequency through SpeedStep technology, and the power consumption can be reduced by 40%.

flammable gas

■ The cooking time of big fire is shorter than that of small fire, which can reduce the heat loss. But it is not advisable to let the fire exceed the bottom of the pot to avoid wasting gas.

■ When the temperature is high in summer, don't cover the water before boiling, let the water with lower temperature than air exchange heat with the air, and then cover the water when the water is naturally heated to the air temperature, which can save gas.

■ Before cooking, dry the water droplets outside the pot. Try not to steam the food that can be cooked. Cook the food that is not easy to cook in a pressure cooker or stainless steel pot, and do not use oil fumes. Heat the cooked food in a microwave oven. It also helps to save gasoline.

■ Holding short meetings is also a kind of saving. Lighting, air conditioning and power for public address can be saved. Perfume that is about to expire can be sprayed on dried flowers stuffed in pillows, on washing water and on mopping the floor.

■ Unplug any electrical appliances as soon as they are not used.

■ Use public transportation as much as possible, make shopping plans when driving out, and try to buy at one time. Walk more, ride a bike, take the light rail subway and drive less.

■ Energy-saving when driving: avoid cold start, reduce idle time, avoid sudden speed change, choose appropriate gear to avoid high-speed and low-speed operation, change oil regularly, do not open the window at high speed, and have appropriate tire pressure.

■ Use instant messaging tools such as e-mail and MSN more, and use fax printers less.

■ A variety of trees.

What is a low-carbon diet?

"low-carbon diet"

1972, Dr. Atkins's "New Diet Revolution" was first published, which proposed a brand-new diet. Prior to this, dieting methods either advocated reducing the daily intake of calories or reducing the intake of fat and carbohydrates at the same time. However, the diet proposed by Dr. Atkins only focuses on strictly limiting carbohydrate intake. So, what are carbohydrates?

You may have heard of "carbohydrates" and "complex carbohydrates". Carbohydrates come from a wide range of sources, such as rice, pasta, bread, biscuits, grains, fruits and vegetables. Carbohydrates provide basic energy for the human body. You can compare the relationship between body and carbohydrate to the relationship between car engine and gasoline.

The simplest carbohydrate is glucose. Glucose, also known as "blood sugar" or "glucose", flows with blood, so it can be used by cells all over the body. Cells in the body absorb glucose and convert it into energy needed for cell activities.

The word carbohydrate comes from the fact that glucose is composed of carbon and water. The chemical molecular formula of glucose is C6H 12O6.

[Edit this paragraph] Low-carbon life-low-carbon interesting talk in entertainment circle

Do you know that?/You know what? Do you know that?/You know what? Madonna, the music queen, has been criticized recently. Environmental experts predict that her global concert tour will cause 65,438+0,635 tons of exhaust pollution. Look at the account calculated by environmental experts for her: 95 tons of exhaust gas from private jets; 250 staff members take passenger planes, with carbon pollution 1080 tons; Freight traffic, carbon emissions reached 460 tons.

Although "low-carbon life" is a new concept, it reflects the old problem of sustainable development in the world, it reflects the concern for the future caused by climate change, and the world is increasingly aware of this problem. Climate problems such as global warming force human beings around the world to consider the current ecological environment.
