Ensuring energy security and promoting energy revolution with the goal of "double carbon"

A model of pumped storage power station is composed of photovoltaic panels all over the mountains, wind power stations standing one after another, a surface reservoir and an abandoned mine. At the 2022 China (Taiyuan) International Energy Industry Expo held during the forum, this project, which combines traditional coal mines with green power, attracted many viewers’ attention.

"Using the roadway of the closed mine and the accumulated mine water in Taiyuan Dongshan Coal Mine to form the’ underground reservoir’ of the pumped storage power station can not only reduce investment, but also promote the consumption of new energy in the surrounding areas." Wang Pengjie, director of China Huaneng Group Clean Energy Technology Research Institute Co., Ltd. said.

Pumped storage in abandoned mines, hydrogen production from electrolyzed water, carbon dioxide capture devices, green mining in coal mines … The words green, energy saving and carbon reduction can be seen everywhere at forums and exhibitions, which has become the epitome of China’s deepening energy revolution and actively and steadily promoting the goal of carbon neutrality in peak carbon dioxide emissions.

According to the data from the National Development and Reform Commission and the National Energy Administration, since 2012, China’s energy consumption intensity has decreased by more than 26%, the proportion of coal in energy consumption has decreased by 12.5 percentage points, and the installed capacity of renewable energy power generation has exceeded 1.1 billion kilowatts. The installed capacity of hydropower, wind power and photovoltaic power generation has ranked first in the world for many years.

"As the largest developing country, China will complete the largest decline in carbon emission intensity in the world and move from the peak of carbon emission to carbon neutrality in the shortest time in history. This is not easy to achieve and requires hard work." Xie Zhenhua, China’s special envoy for climate change, said.

Based on the basic national conditions of being rich in coal but poor in oil and gas, it is an important task for China to promote high-quality energy development by promoting green and low-carbon transformation on the premise of ensuring energy security.

As a pilot project of comprehensive reform of the national energy revolution, Shanxi seized the strategic opportunity and accelerated the adjustment of industrial structure and energy structure. At present, the advanced coal production capacity in the province accounts for 79.4%, all coal-fired generating units in service have achieved ultra-low emissions, and the total installed capacity of wind power and photovoltaic has reached 31.8%. Breakthroughs in cutting-edge technologies such as hydrogen energy, sodium ion batteries, smart mines and energy Internet have been accelerated.

The main person in charge of the Shanxi Provincial Party Committee said at the forum that based on the present and facing the future, Shanxi will take the "five integrations" of coal and coal power, coal power and new energy, coal and coal chemical industry, coal industry and digital technology, coal industry and carbon reduction technology as the main direction, and strive to embark on a green and low-carbon development road with Shanxi characteristics.

Low-carbon transformation of new technologies, new industries and new occupations has spawned more opportunities.

Achieving peak carbon dioxide emissions and carbon neutrality is an extensive and profound systematic economic and social change. Participants believe that this is not only a huge challenge, but also a valuable development opportunity.

-New technology accelerates iteration. At this forum, a new energy vehicle attracted public attention. In the past three months, this "Longji Green Energy" exhibition car, which is full of photovoltaic sophisticated scientific and technological achievements and solutions, has crossed many cities in China from south to north.

Yao Feng, vice president of Longji Green Energy Technology Co., Ltd. in China, said that Longji Green Energy broke through the conversion efficiency of photovoltaic single crystal cells for 10 times in a year and became the world record holder of the conversion efficiency of photovoltaic single crystal cells.

"’Double Carbon’ is pushing global science and technology to accelerate innovation." Qian Zhimin, chairman of the State Power Investment Group, said that the current integration and innovation of energy, digitalization and intelligence has made it possible for China to develop rapidly in energy-related science and technology fields.

-New industries developed rapidly. Not long ago, Shanxi Xiangrui Energy Co., Ltd. officially unveiled the electric carbon fusion laboratory established by a number of institutions, trying to link the electricity market with the carbon market and provide data analysis services for market participants. This four-year-old enterprise has seized the opportunity of low-carbon development and quickly laid out low-carbon cloud accounts, virtual power plants and other businesses, and has become one of the leading enterprises in dual-carbon services in Shanxi Province.

Huang Di, director of the Microgrid Division of Zhejiang Oupeng Technology Co., Ltd., said that he came to Shanxi for the first time to participate in the exhibition, and his fancy was the emphasis on low-carbon transportation in various places. The scale effect of new energy commercial vehicles will bring development opportunities for the power exchange model.

"Forestry will be promising in the new round of energy revolution, and bio-based materials, biomass materials and carbon reduction and carbon fixation technologies will usher in the spring of development." Yu Honghui, chairman of China Forestry Group, said that the role and status of forest carbon sinks will become increasingly prominent in the future.

-New occupations are constantly emerging. Rong Shujie from Shanxi Hepo Power Generation Co., Ltd. is an electricity trader. As a "trader", she undertakes important tasks such as daily trading declaration, contract decomposition, settlement management and information disclosure of power plants. In July this year, power traders, carbon emission managers, carbon sink appraisers, and building energy conservation and emission reduction consultants were included in the newly revised People’s Republic of China (PRC) Occupational Classification Ceremony (2022 Edition).

"The energy transformation that will limit the global temperature rise to 1.5℃ higher than the pre-industrial level by 2050 is expected to create more than 120 million jobs in the global energy industry." UN Assistant Secretary-General Navid Hanif said.

China’s energy transformation has provided new development opportunities for the world. "Our factories are located in more than 10 cities in China, and we have set up innovation centers in 4 cities." Ke Weimao, president and global chief operating officer of Honeywell, said that Honeywell has established contacts with many China enterprises to help their products become smarter and safer.

Iceland’s Prime Minister Katerina Jakob Sdottir said that the energy cooperation between China and Iceland was initiated more than 40 years ago, and the cooperation in the field of geothermal energy has expanded from the enterprise level to the fields of education and technology transfer.

Not only bring in, but also go out. The travel cost per kilometer of a car is only in 0.3 yuan, which can reduce the carbon emission by 0.8 tons every 10,000 kilometers, and the fuel cost of a heavy truck is about 1 yuan compared with that of a traditional diesel vehicle … Geely methanol hybrid car and methanol heavy truck were delivered in Jinzhong City, Shanxi Province a few days ago. Relying on mature methanol technology, methanol vehicles have gone to Iceland, Denmark and other countries.

In March this year, the methanol car and long-distance methanol heavy truck developed and produced by China Zhejiang Geely Holding Group started the test and demonstration operation in aalborg Port. "I think it is very important to have strong cooperation in this field. This is not only about ourselves, but also about the well-being of future generations. " Trina Bramsen, Danish Minister of Transport, said.

"I welcome China’s global leadership in the field of renewable energy investment, and express my appreciation for China’s grand development plan put forward in the 14 th Five-Year Plan." UN Assistant Secretary-General Navid Hanif said. (Reporter Zhao Donghui, Chai Hailiang, Liang Xiaofei, Wang Jinyu)

　　The Beijing Municipal Center for Disease Control and Prevention recently issued the Guidelines on Key Prevention and Control Measures that the public should always adhere to, suggesting that people should always wear masks, keep social distance, maintain hand hygiene, cooperate with health monitoring, do a good job in food hygiene, and do a good job in daily cleaning and disinfection.

　　Summer has arrived, and the epidemic in COVID-19 is still raging.

　　According to Yu Xuejie, dean of the School of Health of Wuhan University and an infectious disease expert, at present, it is summer in the northern hemisphere and winter in the southern hemisphere. However, Covid-19 is not afraid of cold and heat, and it continues to spread all over the world. Some experts believe that Covid-19 may not be completely eliminated in a few years, and people must accept the fact that it will exist for a long time. Especially with the resumption of work, the return of a large number of people and students, the increase of traveling residents, and the risk of importing cases, the epidemic prevention and control work is still arduous and arduous.

　　High temperature and epidemic prevention pressure

　　The World Health Organization (WHO) and the World Meteorological Organization (WMO) held an expert video conference not long ago, pointing out that the superposition of COVID-19 epidemic and the adverse health effects of this summer’s heat wave will bring new challenges to epidemic prevention and control and public health safety, reminding countries to attach great importance to it and do a good job in coping with the heat wave under this year’s epidemic.

　　There have been some speculations that the high temperature in summer may delay the spread of Covid-19. However, WHO said that the latest research did not find that meteorological factors such as temperature, humidity and ultraviolet radiation were significantly related to the spread of Covid-19. Therefore, experts pointed out that even if the hot summer comes, people should still be highly vigilant against Covid-19, especially in the hot and humid environment, the risk of transmission of Covid-19 still exists, and it is necessary to seriously abide by various prevention and control measures. At the same time, the World Meteorological Organization warned that although the influence of high temperature on the spread of Covid-19 is not obvious, the heat wave will cause other damages to human health and health system.

　　Countdown to The Lancet 2030 reports that people in all parts of the world are extremely vulnerable to extreme high temperatures. High temperature, high humidity and strong radiation weather can cause a series of physiological function changes in human body temperature regulation, water and salt metabolism, circulatory system, nervous system and urinary system. Once the body can’t adapt, it will cause abnormal temperature rise and lead to heatstroke. At the same time, extreme high temperature will also worsen chronic diseases such as cardiovascular and cerebrovascular diseases, respiratory diseases and diabetes, and increase the number of deaths.

　　A Guide to Epidemic Prevention in Hot Weather edited by the World Meteorological Organization says that all diseases and deaths related to hot weather can be prevented, and full preparations should be made according to the actual situation in COVID-19.

　　Should I wear a mask?

　　As a "protective standard" when going out, people have gradually become accustomed to its existence. However, as the weather gets hotter and the ultraviolet rays strengthen, the sultry feeling of wearing a mask and some skin problems become more and more prominent. Therefore, how to do personal protection in hot summer has become a problem for many people.

　　It is undeniable that wearing a mask is an effective way to block the spread of Covid-19. However, in a hot environment, does wearing a mask increase the risk of heatstroke?

　　Disease control experts pointed out that it is necessary to adhere to the scientific wearing of masks and develop a good habit of carrying masks with you. Regarding whether or not to wear masks, low-risk areas should wear masks according to the Guidelines for Wearing Masks for Public Science (Revised Edition) issued by National Health Commission.

　　Wang Chen, an academician of China Academy of Engineering and dean of China Academy of Medical Sciences, said that wearing a mask should be judged according to different situations, and it is not necessary to wear a mask in an open, ventilated and sparsely populated place; Wear masks when taking public transportation (cars, trains, planes, ships, etc.), going to closed spaces such as shopping malls, vegetable markets, office buildings, and going to hospitals; If you are not sure whether you should wear a mask when you go out, you can always keep a mask with you so that you can wear it when you should. In addition, for some key people, such as doctors, staff in closed places, patients with chronic diseases, the elderly, etc., masks should be worn in public places; People with respiratory symptoms should take the initiative to wear masks.

　　Scientific use of air conditioning

　　When the heat wave strikes, it is inevitable to use air conditioning. If you are too worried about the spread of Covid-19 and don’t use air conditioning, it will lead to health hazards such as heatstroke, but excessive use of air conditioning will also lead to the decline of human immunity and make you more susceptible to diseases.

　　In this regard, experts said that people who use household air conditioners need to disinfect the air conditioners, and it is not advisable to keep the indoor temperature below 26 degrees Celsius, and pay attention to opening windows frequently for ventilation; Public places and offices that use central air-conditioning and ventilation systems should also use central air-conditioning and ventilation systems safely, and take various measures to prevent and control epidemic situations in public places.

　　When using central air conditioning, it is required to turn off the return air and run with fresh air, and the air between rooms is required to be independent, and the fresh air should be opened as much as possible. If there is a disinfection device or purification device, the central air conditioner should be turned on during the epidemic period, and the filters at the air outlet and return air outlet should be cleaned every week.

　　Experts pointed out that it is necessary to keep indoor air circulation and standardize the use of air conditioners to avoid air pollution. Air conditioning and fresh air system are two independent indoor systems, one for adjusting temperature and the other for improving indoor air quality. The central air conditioner should be able to release enough fresh air and ensure independent return air or no return air. If the central air conditioner in the indoor place cannot meet the above standards, the central air conditioner should be turned off, and the independent single air conditioner can be used. If it is not clear whether there are infected people in the people covered by central air conditioning, then everyone should wear a mask (indoors) until the risk is reduced.

　　Can mosquitoes spread viruses?

　　As the weather gets hotter and hotter, there are more mosquitoes. Many people are worried about whether Covid-19 will be spread by mosquitoes.

　　Lin Minggui, Executive Director of Infectious Diseases Department of Tsinghua Chang Gung Hospital, pointed out that mosquito bites can indeed infect many diseases, but there is no evidence that Covid-19 can be spread by mosquitoes at present, so the public need not panic. But in any case, keeping the family and the surrounding environment clean and reducing the appearance of mosquitoes can not be ignored.

　　"Malaria, dengue fever, Japanese encephalitis, filariasis, etc. can all be spread by mosquitoes." Lin Minggui said that when summer comes, we should take active actions to comprehensively and scientifically prevent and control mosquito hazards. For example, vases and aquatic plants at home should be changed frequently, at least once a week, and the accumulated water in the bottom plates or trays of flowerpots should be kept clean. We should pay special attention to the places with water in dark corners and clean up the air-conditioned trays, bathrooms and kitchen floor drains in time. Besides, many people think there are no mosquitoes during the day, so there is no need to be afraid. Lin Minggui said that mosquitoes are not all from Nocturnal Animals, so it is also necessary to prevent mosquitoes during the day, especially when going out to places with more plants and water.

　　Pay attention to susceptible people

　　The elderly over 65 years old are susceptible to Covid-19 and heat wave, and the mortality rate of Covid-19 infection and the risk of heatstroke will increase with age. In addition, people suffering from chronic basic diseases such as cardiovascular diseases, lung diseases, kidney diseases, diabetes, obesity, outdoor workers, medical workers and social service providers, pregnant women, etc., especially need to be protected.

　　Public health experts suggest that the public should try to avoid going out during the heat wave, work outdoors in the shade as much as possible and pay attention to replenish water in time; Pay attention to keep the living and working environment cool; Ensure effective contact with susceptible people who are isolated or living alone, and provide timely assistance in case of heatstroke reaction; Ensure that medical workers and social service personnel wearing protective devices are in a cool working environment.
