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. ...

We can also make appropriate adjustments according to different environments and locations.

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 led to a certain increase in the prices of food, meat, edible oil and other items. 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 a low-carbon economy and a 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 1 10,000 kwh of electricity a year, which is equivalent to saving about10.8 million tons of standard coal and reducing carbon dioxide emissions by about 45,000 tons. 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 kg. 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.

My low carbon life

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.

Global warming, iceberg melting, sea level rising, species extinction, people fleeing everywhere. How horrible! The movie "20 12" describes "the end of the world"? In the face of global warming, all countries are doing the work of preventing global warming. Such as planting trees and reducing carbon dioxide emissions.

The earth is our home. As the masters of the earth, we should take good care of it. Now the city is not a civilized environment, as long as it does not pollute the earth's environment and waste the earth's energy. Can make the city greener and more environmentally friendly. If you have an idea, you must act. "Low carbon emission reduction" is not far from us. Let's start with the details of life. For example, people who have cars at home drive less and ride more, even if they drive less than one day a month. It seems like a meager act, but you have made contributions to the country. Everyone learns from your actions, so your contribution to the world is immeasurable. Let's go! Do our best, do our little bit!

Like me, I have made a modest contribution in my life. I usually water vegetables with leftover rice. Taomi water is more nutritious to vegetables than clean water, which not only saves water, but also makes flowers and plants grow better. Besides, the water from washing clothes in my house is collected for flushing toilets and mopping the floor. Although it takes a lot of effort, I will save the amount of napkins and toilet paper, because I can make full use of water resources and use degradable plastic bags as garbage bags at home. Every day, 270,000 trees are cut down to produce paper towels. What a terrible number! Everyone must save using napkins and toilet paper!

Students and friends, achieving low-carbon environmental protection is only an attitude, not an ability. "An energy-saving lamp environmental protection bag has little effect on energy conservation and emission reduction, but as long as110 of 654.38 billion people use it to save energy and emission reduction, it will be astronomical! Waste less paper, save electricity and strive for a low-carbon life. Let's pay attention to the climate, save energy and reduce consumption, protect the environment and contribute to saving the earth!

With the development of science and technology, most people live a well-off life. In addition to ensuring food and drink, private cars are gradually increasing. People's lives are getting richer and richer.

At the beginning of the new century, mankind paid a price for this: a large number of polluted gases were discharged, which destroyed the oxygen layer of the earth, and the oxygen layer over Antarctica was destroyed, resulting in a big hole. Glaciers in the North and South poles have melted one after another, threatening polar creatures. Without the protection of the large oxygen layer, the greenhouse effect also threatens the whole earth. Global warming is caused by the destruction of the oxygen layer, and the ultraviolet rays generated by the sun irradiate the earth, which makes the earth warm ... If this continues, the earth will become a fireball!

Is there any saving? Of course there is. As long as from now on, starting from us, take practical actions to protect the earth and save ourselves-live a low-carbon life.

Low-carbon life mainly starts with basic necessities of life. Buying less unnecessary clothes can reduce carbon dioxide emissions by 2.5 kilograms. Eat more vegetarian food and reduce carbon dioxide emissions from meat. Choose a small apartment without excessive decoration. Drive less and take more buses, which can reduce carbon dioxide.

In addition to these necessities, there are some tips for saving.

The water pipe under the washbasin can be replaced with a waste bucket. Good water flows into the bucket along the hole, and the water can be used to flush the toilet.

I also made a "descaler" with waste bottle caps, and staggered five or six beer bottles or beverage bottle caps on a board, leaving the handle. Using this self-made brand "scale remover" is not only convenient and economical, but also really low-carbon!

A box of milk, what should I do if I run out of milk? The first thought is to throw it away! This can't be done. If you want to be "low-carbon", you must learn to transform the law!

The milk box is transformed into a desk lamp: the milk box is placed horizontally, and the drinking water port is cut with scissors to make a cuboid with holes. Cut a hole in the wide face, put a water pipe, put the wire in, connect the light bulb and put the light bulb in the box. Fix it on the table with another milk box!

The milk box was transformed into a storage box. Small things that are usually lost are perfect in a box. The storage box is also very simple, just cut a hole on both sides to put things!

The milk box of the third of the eighteen martial arts turned into a lovely and beautiful pen container. Clean the box first, then carefully cut off the top of the box with a knife, and the box becomes a cuboid without a cover. Next, you can wrap it in paper or decorate some patterns on your favorite garbage bag!

Achieving "low carbon" is simple. I believe that anyone can contribute to the earth.

low carbon life

The global crisis caused by carbon dioxide has aroused people's sense of urgency. Even though countries around the world are still trying to reduce emissions, the concept of low carbon has almost been widely recognized.

Low-carbon life represents a healthier, more natural and safer life, and it is also a low-cost and low-cost lifestyle. Low carbon is not only a corporate behavior, but also a lifestyle that conforms to the trend of the times.

What should we do for a low-carbon life? Start with the details:

Use less paper towels, pick up handkerchiefs and print every piece of paper on both sides, which is equivalent to retaining the second half of the forest that was originally to be cut down; Planting trees pays for the carbon dioxide you emit, how much you discharge and how much you suck; Greening is not only planting trees in the suburbs, but also planting some flowers and plants at home without driving.

Turn off unused computer programs, reduce the workload of hard disk, save electricity and maintain your computer; The power consumption of a TV set in standby state is generally about 10% of its starting power, which is really not small. /kloc-throwing batteries around 0/0 years ago can be ignored, and now it is completely irresponsible; If you just use the computer to listen to music, the monitor can only be dimmed or turned off altogether.

Some people, especially women, use forty or fifty liters of water for a bath, and cleanliness is not so exaggerated; It's just a psychological effect to think that turning on the faucet to the maximum can wash the dishes more cleanly. It can be said that climate warming is partly due to revenge for excessive use of air conditioning and heating.

There are many, many things above, which are small things within our power. Everyone contributes to the earth, and everyone treats our earth well. The earth will definitely make our life better! Reduce the energy cost of power consumption

With the end of the Copenhagen World Climate Conference held on June 5438+February 19, 2009, it clearly indicates that the low-carbon era has come, and all countries and enterprises will soon be involved in this low-carbon trend. At the two sessions in March, low carbon, energy saving and environmental protection also became one of the hot topics for delegates.

Low carbon economy is one of the most popular words in recent years. Just a few years ago, many people may not have heard of the term low-carbon economy at all, but now, this term is everywhere, even the aunt of the neighbor will say it. The so-called low-carbon economy is a green economy based on low energy consumption and low pollution. Its core is to promote the development and application of energy efficiency improvement technology, energy saving technology, renewable energy technology and greenhouse gas emission reduction technology, and to promote the transformation of the whole social economy to the mode of high energy efficiency, low energy consumption and low carbon emission.

At present, many countries in the world, including China, are actively developing low-carbon economy and have set off a low-carbon economic revolution. Taking China as an example, we are not only vigorously adjusting the industrial structure of the energy industry, increasing the proportion of emerging energy sources such as wind power generation, solar power generation and nuclear power generation, but also reducing the proportion of thermal power generation, so as to make the energy industry develop in the direction of low carbon and non-carbonization. We also actively develop low-carbon new materials, life sciences, biomedicine, information networks, space ocean development and geological exploration, and strive to reduce carbon emissions per unit of GDP by 40% in 2020 compared with 2005.

Draw a perfect carbon footprint

In low-carbon economy, enterprises play a decisive role. This is because compared with individuals, enterprises undoubtedly have greater energy consumption and carbon emissions. At the same time, as individuals, most of the day is spent in enterprises, and their energy consumption and carbon emissions are also closely related to their enterprises. Therefore, in order to actively participate in the low-carbon economy, enterprises should start from me, fulfill their civic responsibilities, pay attention to energy conservation and environmental protection from all aspects of enterprises, and draw a clear carbon footprint.

The easiest thing to do is that enterprises can control the air conditioning temperature (not too low in summer and not too high in winter) according to national requirements, and adopt energy-saving lamps and other measures to achieve the effect of energy saving and emission reduction. Further, IT is to strengthen the monitoring of carbon footprint of IT products. With the continuous improvement of office automation and informatization, enterprises are increasingly dependent on IT products, and there are more and more IT equipment. If you look around, IT is not difficult to find that employees in enterprises spend most of their time using various IT equipment (such as computers, printers, networks and other products), and enterprises must also pay attention to the important role of these IT products in energy conservation and emission reduction.

In fact, with the widespread popularity of computers and other products in enterprises, the carbon emissions of these products are also rising in the whole carbon emissions-data show that the carbon emissions of ICT industry (information and communication technology industry, including IT industry and communication industry) were 530 million tons in 2002, and this figure will soon climb to 65.438+0.43 billion tons in 2020, accounting for 4% of the total carbon emissions. This is undoubtedly a huge number. As an enterprise, we must choose those green and energy-saving IT products and use advanced information technology to reduce energy consumption.

For example, enterprises can choose computers or servers with high overall performance-to-power ratio to reduce overall power consumption. At the same time, more consideration should be given to similar computer and server products with power conversion efficiency over 90%, which can perfectly and effectively reduce power consumption. Alternatively, enterprises can use laptops instead of desktops, thus reducing overall power consumption.

In the construction of enterprise network environment, enterprises can also make it greener through various strategies. For example, enterprises can use wireless LAN instead of wired LAN, which can reduce cables, energy consumption and environmental pollution. More importantly, enterprises should pay attention to the choice of green products when choosing network equipment-compared with PC, most network equipment such as switches and routers need to run 24 hours, which requires more attention to the green energy-saving characteristics of products. Therefore, the adoption of HP ProCurve series network products with high energy efficiency and low heat dissipation will greatly reduce energy consumption and power cost, greatly improve the return on investment and depict a perfect carbon footprint. For example, HP ProCurve network products have variable speed cooling fans for efficient cooling. The distributed computing structure can be adjusted according to the deployment scale of switches, thus optimizing power consumption; Support remote management of each port, and also reduce power consumption and energy costs; What everyone can do is "a drop in the ocean"

Discussion on low-carbon life of energy saving and emission reduction

Now the most popular slogan is "energy saving and emission reduction, low-carbon life". First of all, what is energy saving and emission reduction? As the name implies, it is to save energy and reduce pollution emissions. Knowing the significance of energy conservation and emission reduction, let's talk about the most important and practical problems. How to save energy and reduce emissions? "Save water and electricity, save paper, treat waste water and waste gas ..." Many people will say so. Generally speaking, this is probably the case, but the specific implementation needs specific methods. For factories, environmentally friendly and economical equipment is essential. In our daily life, starting from every detail of life, the situation will be greatly improved. First of all, we should learn to save energy. The water resources that our earth has now; Forest resources; Biological resources; Atmospheric resources are limited and can be continuously regenerated. However, due to our wanton destruction and abuse of chemicals, they not only cannot be regenerated, but also cause a series of ecological disasters, which pose a serious threat to our human survival. Take our water resources as an example! Although we are often called on to save water in the news now. For example, we can mop the floor with vegetable washing water and then flush the toilet with dirty water, but people still don't pay attention to it and waste water resources. In my unit, the sound of water "ticking" is often heard, which is caused by people's carelessness in saving water. Although wasting a drop of water will not have much impact on society, let's imagine that if everyone wastes a liter of water with this mentality, the population of more than 65.438+300 million in China will waste 65.438+300 million liters of water a day. Simply understood, low-carbon life is to return to nature and carry out activities between human beings and nature. Low-carbon life represents a healthier, more natural and safer life. At the same time, it is also a low-cost and low-cost lifestyle, and it is also a lifestyle that conforms to the trend of the times. Let's start from this moment, bit by bit, and let "low carbon lead" lead the new fashion of life.
