Over the past 200 years, with the deepening of industrialization, a large number of greenhouse gases, mainly carbon dioxide, have been emitted, which has led to global temperature rise and climate change. This is an indisputable fact. According to the report released by the World Meteorological Organization, the last 10 year was the hottest year in the world on record. In addition, global warming has caused Antarctic glaciers to begin to melt, which in turn has led to sea level rise.
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. "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. "Low-carbon life is actually very simple to do, such as: replacing the electronic alarm clock with a traditional clockwork alarm clock; Once the lights and air conditioners are not used, turn them off; Use jogging in the park instead of treadmill exercise; Replace light bulbs with energy-saving lamps; Do not drive, ride a bike, etc.
Climate change is not only concerned by environmentalists, experts and scholars, but also closely related to each of us. If you think that your own strength is insignificant to the whole planet, then why do you live a low-carbon life? Then you are wrong, you know? An energy-saving lamp and a solar water heater have really little contribution to energy conservation and emission reduction, but as long as110 of 300 million people use it, the energy saved and carbon emissions reduced will be astronomical!
Low-carbon life can make our bodies healthier and the environment more beautiful. Why not?
In recent years, energy shortage and environmental pollution have become the focus of world attention. Changing the traditional economic growth mode of high energy consumption and high pollution, vigorously promoting energy conservation and emission reduction, developing a low-carbon economy marked by low energy consumption and low emissions, and realizing sustainable development are becoming the common choices of economic development in all countries of the world.
As a large developing country, China's energy and environmental problems are particularly prominent. In 2007, the report of the 17th National Congress of the Communist Party of China first put forward the concept of "building an ecological civilization, basically forming an industrial structure, growth mode and consumption mode to save energy and resources and protect the ecological environment", which pointed out the direction for sustainable development and made people pay more attention to the rise of low-carbon economy.
The essence of low-carbon economy is the problem of high energy utilization efficiency and clean energy structure, and the core is the fundamental change of energy technology innovation, system innovation and human survival and development concept.
The development mode of low-carbon economy provides an operable interpretation for energy saving and emission reduction, developing circular economy and building a harmonious society. It is an all-round innovation and practice to implement Scientific Outlook on Development and build a conservation-oriented society, completely in line with the development ideas put forward in the report of the 17th National Congress of the Communist Party of China, and it is a global revolution involving modes of production, lifestyles and values.
Ma pointed out that we should pay attention to the boundary effect of resources, energy and environment. He said that in the face of the dual threats of energy and environment, we must deeply reflect on the shortcomings of the theory that consumption stimulates demand and promotes economic growth under the background of western scientific rationalism. It is time to find an economic growth model that pays more attention to the boundary effects of resources, energy and environment and explore new economic theories.
The process of human survival is the process of consuming energy and discharging substances harmful to the environment to nature. Carbon dioxide is the inevitable product of human consumption of energy and resources, and it is also the chief culprit of greenhouse effect and environmental problems. With the increase of population and the rapid expansion of activity energy, human activities have endangered the foundation of their own survival.
According to statistics, as the largest energy consumer in the world, the United States consumes 30% of the world's energy with 6% of the world's population. However, China's energy consumption per unit GDP is eight times that of Japan, and its population is several times that of the United States. According to this development model, we lack lasting innovation ability, and environmental degradation and energy shortage will be the biggest bottlenecks for China's development in the next 50 years. It has become an irreversible trend to save energy and reduce emissions, realize low-carbon development and build an ecological and civilized society.
The stern review, led by Nicholas Stern, the former chief economist of the World Bank, pointed out that the annual 1% GDP investment in the world can avoid the loss of 5% ~ 20% GDP in the future, and called for the global transition to a low-carbon economy. In July, 2007, the United States Senate put forward the Low-carbon Economy Act, which indicates that the development path of low-carbon economy is expected to become an important strategic choice for the United States in the future. Germany hopes that in 2020, the domestic low-carbon industry will surpass its automobile industry. The transition to a low-carbon economy has become the general trend of world economic development.
As a country with high energy consumption, we need to find the source of China's huge social waste and environmental pollution from the inherent laws of energy conservation, emission reduction and low-carbon development. We must abandon the specific technical problems that only focus on the "use" level, such as building energy conservation and efficient utilization of coal, while ignoring the chronic diseases existing in the "body" level, such as the negative impact of consumption-driven economic growth theory, the spatial layout of urban and rural areas, and the huge waste of national lifestyle. Therefore, only by innovating thinking, changing ideas, adhering to the combination of body and function, and starting from the perspective of overall situation and system theory, can we correctly understand and accelerate the development of low-carbon economy.
1. Advocate the concept of green consumption and green management, and form a low-carbon lifestyle. We must change the concepts of the public and society and do everything moderately and reasonably. For individuals, it is necessary to cultivate the concept that saving is a virtue and completely change the bad habits such as food waste that run counter to energy conservation and emission reduction; For enterprises, it is necessary to implement the concept of green management and establish a clean production mechanism and a lean production model; The state guides enterprises to incorporate environmental protection costs into production costs, helps enterprises to establish corporate citizenship awareness, and solves the misconception that energy conservation and emission reduction are not effective.
2. Solve the huge waste hidden in the spatial pattern and social development pattern. Effective energy conservation and emission reduction must be based on the relative concentration of industries, which can produce specialized division of labor, improve efficiency and save energy; At the same time, it promotes cluster innovation and constantly produces new technologies and processes, thus reducing material consumption.
3. Cultivate vein industry and establish a complete industrialization system. At present, people's understanding of circular economy system is still superficial, which is basically understood as waste residue utilization and tail gas recovery. The real circular economy system should be like the human body system. If the industrial manufacturing system is compared to the arterial system of the human body, then the recycling of our waste industrial products should be like the venous system of the human body. Recycling of industrial products-"vein" industry should be a huge industry.
4. Vigorously develop low-carbon technologies to solve the problems of independent innovation achievements and lack of talents. Low-carbon technologies include new technologies to effectively control greenhouse gas emissions in the fields of renewable energy and new energy, clean and efficient utilization of coal, exploration and development of oil and gas resources and coalbed methane, and carbon dioxide capture and storage. It is necessary to strengthen the ability of independent innovation, encourage enterprises to develop low-carbon technologies and low-carbon products, integrate existing low-carbon technologies in the market, and rapidly promote their application.
The accelerated development of low-carbon economy urgently needs the support of a large number of cutting-edge scientific and technological talents and achievements. Take the current situation of talents in the field of new energy as an example. At present, no more than 50 people in China wind power industry have received long-term professional and technical training. Today, two years after the implementation of China's Renewable Energy Law, only North China Electric Power University has established a renewable energy college. In addition, the traditional evaluation and certification system of innovation achievements has some embarrassing realities that the existing scientific system can't explain and the achievements can't be recognized. The major scientific and technological achievements in the future are likely to come from self-taught scientific workers. In the face of the results that cannot be explained by the existing scientific system, we should adopt the method of "non-knowledge principle" combined with empirical research to identify them.
5. Accelerate the construction of cultural and creative industries. Cultural and creative industries are at the high end of the value chain of technological innovation, research and development, and are high value-added industries and low-carbon consumption green industries. Vigorously developing the cultural and creative service industry can create huge wealth for the society and avoid the problems of excessive energy consumption and environmental pollution.
6. Control urban pollution from rain and sewage diversion. There are basically no rain and sewage diversion facilities in county-level cities across the country. Although the investment in rain and sewage diversion facilities in large and medium-sized cities is large, the implementation is not thorough enough, which leads to a large number of labor achievements of sewage treatment plants being "rejected by one vote" by the rain and sewage diversion measures that cannot be fully implemented.
7. Starting from China's energy structure and grasping the main aspects of contradictions, we can improve the efficiency of energy conservation and emission reduction. The main forms of energy consumption in China are electricity consumption, rural heating and urban central heating consumption, and electric energy consumption, of which about 68% of energy is converted from various energy sources and consumed. However, the problems of low operating efficiency and serious energy waste generally exist in China's power system, especially in the two links of power distribution and power consumption. The total energy saving potential is 65.438+0.2 billion kilowatts, accounting for 20% of China electric power. Focus on promoting major independent innovation projects in the field of power distribution and electricity consumption, which can greatly improve the efficiency of energy conservation and emission reduction.
8. The core of low-carbon economy is to build renewable energy in China and even the world.
The source system finally realizes the leap from "high carbon" era to "low carbon" era, and truly realizes the harmonious development between man and nature.
"Low-carbon life" refers to reducing the energy consumed in daily life as much as possible, thereby reducing the emission of carbon, especially carbon dioxide, thereby reducing the pollution to the atmosphere and slowing down the ecological deterioration, mainly changing the details of life from three aspects: electricity saving, solar terms and recycling.
Greenhouse gases give the earth a high fever. Over the past 200 years, with the deepening and development of industrialization, a large number of greenhouse gases, especially carbon dioxide, have been emitted, leading to global temperature rise and climate change. This is an indisputable fact. On February 8, 65438, the World Meteorological Organization released the report "Global Climate Situation in 2009" ahead of schedule, which pointed out that the recent 10 year was the hottest year in the world on record. In addition, global warming has caused Antarctic glaciers to begin to melt, which in turn has led to sea level rise. According to the latest survey published by Finnish and German scholars, the sea level may rise by 1.9 meters by the end of this century, directly threatening millions of urban residents from Tokyo to Shanghai to New Orleans. 65438+ A study published by American media on February 5th pointed out that the earth fever has also caused a huge crisis to human health. First, allergies are aggravated repeatedly. Studies show that with the gradual increase of carbon dioxide level and temperature, the flowering period is advanced, the pollen production is increased, and the spring allergy is aggravated and repeated. Secondly, species are becoming more and more "pocket-sized". With the global temperature rising, biological forms are shrinking, which has already appeared in Scottish sheep. Third, kidney calculi is increasing. Due to rising temperatures and dehydration, researchers predict that by 2050, there will be 2.2 million new patients with urinary calculi. Fourth, the outbreak of foreign infectious diseases, the increase of water environment temperature will make mosquitoes and plankton multiply, and dengue fever, malaria and encephalitis break out from time to time. Fifth, in summer, the lung infection is aggravated, the temperature rises and the cool wind decreases, which will aggravate ozone pollution and easily lead to lung infection. Sixth, algae flooding causes diseases, and the rising water temperature leads to the rapid reproduction of cyanobacteria, which will pollute natural lakes from municipal water supply system, thus causing diseases such as digestive system, nervous system, liver and skin. Low-carbon life has become a lifestyle that human beings urgently need to establish.
Low-carbon lifestyle
Here are some habits of low-carbon life, which are easy to think of and do. The key is to implement. 1. Daily rice washing water can be used to wash hands and clean furniture, which is clean and natural. Not only that, Taomi water can also be used to water flowers, wash hair and make free skin care products. 2. Don't throw away the used mask paper. Using it to wipe the surface of jewelry, furniture or belt will not only shine, but also leave the fragrance of mask paper; 3. Drink the tea residue, dry it and make it into a tea pillow, which is comfortable and helps to improve sleep; 4. Go shopping, bring your own environmental protection bag, whether it is a free or charged plastic bag, and reduce the use; 5. Bring your own drinking cups when you go out to reduce the use of disposable cups; 6. Use permanent chopsticks and lunch boxes, and try to avoid using disposable tableware; 7. Get into the habit of turning off the power supply of electrical appliances at will to avoid wasting electricity; 8. Try not to use refrigerators and air conditioners, and use electric fans or electric fans when it is hot. 9. Replace the electronic alarm clock with the traditional clockwork alarm clock every day; 10. Turn off the computer power during lunch break and after work; 1 1. Once the lights and air conditioners are not used, turn them off; Once the mobile phone is charged, unplug the charging plug immediately; 12. Choose to dry clothes and avoid using drum dryer; Replace 45 minutes of exercise on the treadmill with jogging in a place where the air is fresh and suitable for running, such as a nearby park; 13. Replace 60W bulbs with energy-saving lamps; 14. When using the computer, try to use low brightness and less startup programs. , thus saving electricity; 15. Go out on foot or by bus, and seldom by private car. 16. Use low-carbon and environmentally-friendly daily necessities, such as clothes made of bamboo fiber, towels, underwear, socks, etc., and try not to wear fur clothes. 17. Reduce shopping. If necessary, try to buy it online. 18. In diet, we should give priority to vegetarianism, not because of religious beliefs, but because animal husbandry needs to consume more energy, compared with much less fruits and vegetables. Try to drink less or almost no carbonated drinks such as fruit juice, and you should be more inclined to eat fresh fruit. Making fruit into juice, regardless of juice content, actually consumes a lot of unnecessary energy, creates a lot of unnecessary greenhouse gas emissions, and the container may not be degradable, causing pollution.
Tips for low-carbon life
You may not know about some low-carbon lifestyles, so here are some. 1. The amount of food stored in the refrigerator should be 60% of the volume. Too much or too little food consumes electricity. There should be a gap of about 10 mm between food and refrigerator. 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 startup time. 2. The instantaneous current of the 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 on the electric fan immediately after the air conditioner is turned on. You don't have to turn on the air conditioner all night at night, saving nearly 90% electricity. Set the air conditioner to dehumidification mode. At this time, even if the room temperature is slightly higher, it can make people feel cool and save electricity compared with refrigeration mode. 3. For the same long washing time, when the washing machine works in the weak gear, the motor starts more times, that is to say, using the strong gear actually saves electricity than the weak gear, which can prolong the service life of the 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. 4. Dry food in the microwave oven is mixed with water evenly, covered or wrapped with polyethylene plastic wrap before heating, or heated with heat-resistant glassware with cover. The amount of food heated or cooked at one 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 frequency of turning on and off the microwave oven when thawing food, food can be moved from the freezer to the freezer in advance and thawed slowly, so that the "cold energy" in frozen food can be fully utilized. 5. When the computer is not used for a short time, the energy consumption can be reduced to less than 50% by turning on the "sleep" mode of the computer; 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. Special attention should be paid to the use of notebook computers: fully 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/VISTA, the CPU automatically reduces the frequency through SpeedStep technology, and the power consumption can be reduced by 40%. 6. When cooking eggs and other meals with water to heat food, after the water is boiled, turn off the small fire appropriately, as long as the water temperature is not lowered (the highest temperature of water can only be 100℃, and the water temperature will remain unchanged regardless of whether it is lowered by fire or small fire). 7. Don't leave household appliances in standby state (if you don't understand what standby energy consumption is, please check it out-standby energy consumption). This is not only low-carbon, but also due to the excessive intake of fat, cholesterol and other substances in animals, more and more people suffer from diseases such as hypertension, while the intake of vitamins is very scarce. Even if you eat animals, try to choose herbivores. 9. If the traffic jam lasts too long, put out the fire first and wait for a while (if you don't understand the reason, please check it). 10 wedding is not the face you have struggled for 28 years, nor is it the PK accumulated by your family. Nowadays, simplicity and low carbon are the attached values of sweet civilization.
That's all. There are materials and essays, and you can summarize them yourself.
