Entering the era of low-carbon economy

many people have chosen a more environmentally friendly low-carbon life

the United Nations climate change conference will end on December 18. Some people say that this is another global action after the Kyoto Protocol, which is described as "the last opportunity to save mankind"

coping with climate change and developing a low-carbon economy have increasingly become the consensus of the international community. The central economic work conference proposed that next year we should "carry out pilot projects of low-carbon economy and strive to control greenhouse gas emissions", which is also the meaning of strengthening economic restructuring and improving the quality and efficiency of economic development

what is a low-carbon economy? What impact will it have on China's future development? How much change will it bring to our daily life? How can China walk out of its own low-carbon road? Employees of the power system also have their own views on this

China's commitment to carbon emission reduction and the way to achieve it

China's commitment to emission reduction is the right choice for a large developing country to actively undertake international commitments based on its national conditions

the United Nations climate change conference is coming to an end. On the eve of the conference, the Chinese government promised the world that by 2020, the carbon dioxide emissions per unit of GDP will be reduced by 40% to 45% compared with 2005. The government will take this goal as a binding indicator, incorporate it into the medium and long-term planning of national economic and social development, and formulate corresponding statistics, monitoring and assessment methods

how to correctly understand this emission reduction commitment? Different from the total emission reduction target announced by the United States that "greenhouse gas emissions will be reduced by about 17% on the basis of 2005 by 2020", China's proposed emission reduction target is a unit, and those who simply believe that China's emission reduction target is much higher than that of the United States are incorrect

an important feature of developed and mature economies such as the United States is that economic growth begins to slow down; As a developing country, China's economic development is far from reaching a mature level. As long as policies are appropriate, rapid economic growth can be achieved. Even if the emissions per unit of GDP are significantly reduced, the total emissions may still increase under high-speed economic growth, which is a very simple mathematical calculation problem. Therefore, China's emission reduction commitment is in line with the economic development characteristics of developing countries. It is the right choice for a large developing country to actively undertake international cooperation based on its national conditions. It not only shows China's determination to actively respond to climate change, but also reflects the confidence of the Chinese government to maintain high-speed economic growth

to realize the emission reduction commitment, the government must clearly realize that with the deepening of emission reduction, the potential of energy conservation and emission reduction is getting smaller and smaller, and the realization of unit emission reduction will become more and more difficult. In addition to giving full play to the energy-saving potential, it will become more and more important to improve the value content of unit products. Reducing the energy consumption per unit product and increasing the value of per unit product seem to be the same, which will ultimately promote the realization of the emission reduction target per unit GDP. However, the emphasis of the two is obviously different, and the technical routes chosen are naturally different, so they must be correctly distinguished

the government must also be soberly aware that the role of publicity and education in raising the awareness of energy conservation in the whole society is very limited; Even if our publicity and education are surprisingly successful and everyone has achieved the goal of "turning off the lights at will", the goal of energy conservation and emission reduction will still not be achieved. Of course, we should not deny the existing energy conservation publicity and education, but we must rely on the market, price and economic means to achieve the goal of energy conservation and emission reduction

the establishment of market mechanism should mainly focus on two areas: first, accelerate the market-oriented reform of energy prices, so that energy prices can truly reflect the relationship between supply and demand and scarcity, and fully consider the environmental cost of developing energy, and establish a reasonable price comparison relationship between various types of energy; The second is to give full play to the role of the market in pollution emission control, improve the emission trading system, and reduce the negative externalities of production enterprises in the environment through economic means. If the price of energy and sewage really becomes the indicator of resource allocation, those enterprises and equipment with low energy efficiency and serious pollution will choose to eliminate by themselves, and the implementation of the government's emission reduction plan will be easier, or the government does not need to make a plan in this regard at all

while the market plays a leading role, the government should pay attention to strengthening supervision, maintaining market order, and correcting and making up for market failures in a timely and effective manner. At present, it is more urgent for the government to use economic support policies to vigorously promote the development and application of new and renewable energy, and promote the change of energy consumption structure by changing the energy supply structure

the government should actively guide the economic structure test electromagnetic clutch to develop in the direction of low carbon, gradually increase the proportion of high and low carbon economy in the overall economic scale in storage and transportation, and constantly consolidate the economic foundation of energy conservation and emission reduction, so as to ensure the sustainability of emission reduction per unit of GDP

how the power industry meets the low-carbon era

energy conservation and emission reduction can save more resources for economic development and free up greater environmental capacity

in the face of the global call to control the greenhouse effect, low-carbon economy has become the trend of world development. In the next 10 years, China's economy will continue to maintain rapid development, and the living standards and quality of life of the people will also be further improved. Correspondingly, China's total carbon emissions and energy consumption will also continue to increase. In this case, it is difficult to achieve the goal of reducing carbon emissions by 40% - 45% by 2020. As Ma Heng, a researcher in the new energy industry at the China Investment Securities Research Institute, said, China took the lead in making emission reduction commitments this time, which reflects the Chinese government's willingness to take practical actions to promote the successful conclusion of the Copenhagen conference. At the same time, it is also a response and counterattack to western countries' requirements that China and developed countries undertake the same emission reduction

then, how should the power industry, one of China's key emission reduction industries, deal with the challenge of low-carbon economy? First of all, on the basis of continuing to shut down small thermal power units, such as oxide skin, metal debris, etc., we should pay close attention to the energy conservation and emission reduction links of large units, seek a more suitable survival mode, and meet the arrival of the low-carbon era. The power industry is not only the creator of high-quality clean energy, but also a major consumer of primary energy and pollutant emissions. Therefore, it is also a key area for the country to implement energy conservation and emission reduction. At present, the key to the power industry is to increase scientific and technological research, strengthen technological transformation, and actively develop green coal-fired power technology. For example, extend and expand technologies and products such as plasma ignition, steam turbine flow transformation, boiler dry slag removal, unit detection, combustion optimization, frequency conversion and energy saving transformation, and strive to improve energy conversion and utilization efficiency and reduce environmental pollutants and carbon dioxide emissions. At the same time, carbon capture and storage technology should be further strengthened to reduce the direct emission of pollutants

secondly, we should vigorously develop renewable and clean energy. Developing new energy can not only reduce the dependence on coal and oil, but also reduce carbon dioxide emissions. As Wu Jiang, a researcher at the Research Office of the State Electricity Regulatory Commission, said, using renewable energy such as wind and solar energy to directly replace fossil fuels not only has energy efficiency close to 100%, but also has direct pollutant emissions close to zero. When the cost of wind and solar power generation is high, the technology is relatively backward, and large-scale development is unrealistic, hydropower can be given priority. According to the current survey and design level, China has 2.47 trillion kwh of hydropower technology development. If fully developed, it can provide at least 1 billion to 1.3 billion tons of raw coal energy every year. It can be seen that the development of hydropower can effectively improve China's energy structure. Making good use of abundant hydropower resources is not only the inevitable choice of China's energy policy, but also an important measure to achieve the goal of reducing carbon emissions by 40% - 45% by 2020

low carbon economy is the "touchstone" of scientific development. For a region, an industry and a unit, truly paying attention to and doing a good job in energy conservation and emission reduction can save more resources and free up greater environmental capacity for economic development, find effective entry points and breakthroughs for transforming the growth mode, and promote economic and social development to effectively turn into the track of scientific development, which will have a lasting momentum for development. I believe that with green mountains and clear waters, we will be able to earn back more gold and silver mountains

low carbon economy is beneficial to everyone

to cope with climate change, you can participate by raising your hand; At the end of the year, China has put forward the goal of independent action to deal with climate change, and the Chinese people have a clearer understanding of how to take the "low-carbon" road. Developing low-carbon economy is the only way to deal with climate change

there is such a set of data in the report on coal sustainable utilization and pollution control policies issued by the China Council for international cooperation on environment and development in 2009: by the end of 2008, China's installed power capacity had reached 792million kW, including 600million kW of coal power. By increasing the size and suppressing the size, China's thermal power generation has improved the average efficiency. In 2008, the coal consumption per kilowatt hour has fallen to 349 grams of standard coal, lower than the level of the United States and Germany in 2005. The report also cites a gratifying figure: by the end of June this year, the country had completed the task of shutting down 50million kW small thermal power plants stipulated in the 11th five year plan one and a half years in advance

low carbon economy benefits everyone. While optimizing the energy efficiency and cleanliness level of coal utilization, clean energy such as wind energy, solar energy, hydro energy, nuclear energy and biomass energy are "shining". The article "carbon reduction, China has been acting" published by the people provides a set of data: "At the end of 2008, the proportion of clean energy in China's total primary energy consumption has reached 9%. The installed capacity of hydropower, the scale of nuclear power under construction, the collector area of solar water heaters and the cumulative capacity of solar photovoltaic power generation all rank first in the world, and the installed capacity of wind power ranks fourth in the world. This is a major achievement of China's adjustment of economic structure and transformation of development mode, and also a positive contribution to global climate change in the past 。”

in response to climate change, we also pay attention to forest carbon sink, that is, forest plants absorb carbon dioxide in the atmosphere and fix it in vegetation or soil, so as to reduce the concentration of carbon dioxide in the atmosphere. Relevant data show that every hectare of forest can absorb 20 ~ 40 tons of carbon dioxide and release 15 ~ 20 tons of oxygen every year

to develop a low-carbon economy, everyone is responsible, everyone benefits, and everyone can participate in it by raising his hand; The sky is blue and the water is clear when you raise your hand. Why don't we start with saving water, electricity and paper? Why don't we start by producing less garbage and using more old things? Why don't we start by advocating a lifestyle of walking, cycling, taking more buses and driving less

we are duty bound to carry out the development of low-carbon economy to the end
