The so-called "low-carbon life" is to reduce the energy consumed 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, and pay attention to saving electricity, water, oil and solar terms. In addition to planting trees, some people buy goods with short transportation mileage. Some people insist on climbing stairs, some are interesting, and some are hard to avoid trouble. 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 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 Beijing ......
What kind of lifestyle is low-carbon life?
Environmental protection lifestyle, reduce environmental pollution and carbon dioxide emissions, such as taking more public transport, driving less private cars, turning off the air conditioning faucet when walking, and riding more bicycles.
What is low carbon?
Low carbon means lower emissions of greenhouse gases (mainly carbon dioxide). With the development of world industrial economy.
Low-carbon life advocates a low-energy, low-consumption and low-cost lifestyle to minimize energy consumption, thus reducing carbon dioxide emissions and protecting the global environment from the impact of continuous warming.
What do you think is a low-carbon life? What can be done?
1, use less disposable chopsticks, protect forests and live a low-carbon life. 2. Every piece of office paper is printed on both sides, which is equivalent to retaining the second half of the forest that was originally to be cut down; 3. Turn off the lights, switch and unplug at will, which is the first step and the embodiment of personal cultivation; Don't take the elevator to climb the stairs, save everyone's electricity and change health; 5, the use of environmental protection bags, yes, a plastic bag is fifty cents, but the pollution it causes may be 50 times that of fifty cents; 7. Save electricity, turn off unused computer programs, reduce the workload of hard disk, save electricity and maintain your computer; 9. Considering the contribution of public transportation to the world environment, it can at least offset the sense of superiority brought by driving a private car; 10, use disposable toothbrushes, disposable plastic bags and disposable water cups as little as possible ... because the oil used to make them is also disposable; 1 1. In fact, as an environmentally friendly energy source, the simplest way to use solar energy is to do work as much as possible during the day; 12, eating too much meat hurts at least three objects: animals, themselves and the earth; 13, we can confidently say that saving a bucket of clothes before washing is not because of laziness, but to save water and electricity; 14, cleaning the air conditioner regularly is not only for health, but also saves a lot of electricity; 16, scientific thrift is a fine tradition; After the leftovers are cooled, wrap them with plastic wrap and send them to the refrigerator; Hot steam not only increases the work of refrigerator, but also frosts and wastes electricity. 17, the washing machine is more energy-saving than the weak gear, and it can also prolong the life of the machine; 19. If you use a lot of hot water, you might as well keep the water heater energized to moisturize, because the electricity used for moisturizing one day is lower than that of a box of cold water burned to the same temperature; 20. When cleaning the same car, the water consumption for washing with buckets is only 1/8 of that for washing with faucets. ...
What kind of lifestyle is low-carbon life? 20 points
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.
Low carbon means lower emissions of greenhouse gases (mainly carbon dioxide). It is a low-energy and low-consumption lifestyle. Simply understood, low-carbon life is to return to nature and carry out activities between man and nature. Therefore, low-carbon life is a lifestyle advocated today.
Two examples of low-carbon lifestyle editing
refrigerator
The amount of food stored in the refrigerator should be 60% of the volume. When there is too little food in the refrigerator, the heat capacity will decrease. Opening the refrigerator door will accelerate the release of cold air, and the compressor will start frequently, which will increase the electricity consumption. If the stored food is too full, it is not conducive to the circulation of cold air, and the refrigerator is easy to freeze, which will increase the execution time of the compressor and increase the power consumption. .
There is a gap of more than 10 mm between foods.
air conditioning equipment
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.
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.
washing machine
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.
microwave oven
Dry food is mixed with water, covered with polypropylene 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.
flammable gas
The cooking time of large fire is shorter than that of small fire, which can reduce 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 naturally heats up 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, without oil fume. Heating the cooked food in a microwave oven will also help to save gas.
prescribe a diet
According to the report published by the United Nations in 2006, the greenhouse gas emissions of animal husbandry and aquaculture exceeded the total emissions of all vehicles in the world, including airplanes, trains, cars and motorcycles. Dr. Rajendra K. Pachauri, chairman of the Intergovernmental Panel on Climate Change (IPCC) of the United Nations and winner of the 2007 Nobel Prize, said: "No meat, no cycling and less consumption will help curb global warming".
At the Paris press conference in June, 5438+October, 2008/KLOC-0, he pointed out that the report they released last year emphasized "the importance of changing lifestyle". He said: "This is a concept that the IPCC did not dare to express earlier, but now we must make it public. He appealed to people all over the world, "Please eat less meat! Meat is a product with high carbon emission. "
computer
When the computer is not used for a short time, the energy consumption can be reduced to below 50% by turning on the "sleep" mode of the computer; Turn off unused programs and peripherals, such as speakers and printers; Less hard disk, floppy disk and CD-ROM 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 devices; 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%.

3. Take the stairs instead of the elevator. ......
Introduce what a low-carbon life is in 50 words.
This means that we should do our best to reduce energy consumption, especially carbon dioxide emissions, so as to reduce atmospheric pollution and slow down ecological deterioration. Change the details of life mainly from three aspects: electricity saving, solar terms and recycling. Mobile phone code word is not easy!
When did the low-carbon life begin to be implemented? What is included?
The low-carbon action was first launched in Britain in April 2007, and it is still an important action in the field of climate change in Britain. At present, it has been launched in Australia and the United States, and the operations in China and India have also started. On June 5, 2008, the United Nations Environment Programme put forward a personal "low-carbon lifestyle". Content: The so-called "low-carbon life" is to reduce the energy consumed in daily life as much as possible, thus reducing carbon dioxide emissions.
