China's energy runs out of acceleration
Changes in social electricity consumption, the rise and fall of gasoline prices, and the rise and fall of coal prices? The energy situation has never affected the nerves of the entire Chinese economy and even ordinary people like today.
Through all kinds of mixed appearances of reality, a profound and serious question has never left the vision of the Chinese people and the world: can China's energy support a large country with a 1.4 billion population and a high-quality economic train to move forward smoothly?
The "Report on Energy Development Achievements in the 70th Anniversary of the Founding of New China" released by the National Bureau of Statistics not long ago shows that in the 70 years since the founding of New China, my country's total energy has continued to grow, and the domestic energy production quantity and energy structure have undergone earth-shaking changes. The total energy production has increased by 157.8 times, and the per capita energy consumption has increased by 34.8 times. Natural gas, primary electricity and other energy sources in the energy structure have steadily increased, providing strong support and guarantee for the development of the national economy and the improvement of people's lives.
Energy production to achieve leapfrog development
The role of basic security continues to strengthen
As the basic material basis for human survival and the fuel power of national economic development, energy has always played an important role in improving people's quality of life, promoting national economic growth, geopolitics and international diplomacy.
On June 29, the 500 kV power transmission and transformation project of Shuzhou-Danjing III was successfully transmitted. This four-time flight over the railway line and the transmission line connected by 169 iron towers was successfully put into operation, marking another new clean energy consumption channel in Sichuan.
This is a new passage and a new beginning. From "serious power shortage" to "first delivery", 70 years after the founding of New China, Sichuan electric power industry has grown from scratch, from small to large, from weak to strong, the voltage level of the power grid has been rising, and the transmission capacity has continued to break through.
The great development and change of Sichuan power industry is only a microcosm of the development of China's power industry. Oil, coal, natural gas? In the past 70 years, various fields of energy have also created one miracle after another. China's economic take-off led to the rapid development of the energy industry, strong contrast everywhere:
In 2018, my country's total energy production reached 3.77 billion tons of standard coal, an increase of 157.8 times over 1949, with an average annual growth rate of 7.6.
In 1949, China's crude oil production was only 120000 tons, reaching 0.19 billion tons in 2018, an increase of 1574.9 times, with an average annual growth rate of 11.3 percent.
Raw coal production was only 0.03 billion tons in 1949 and reached 3.68 billion tons in 2018, an increase of 114 times over 1949 and an average annual growth rate of 7.1 percent.
Natural gas production was only 0.01 billion cubic meters in 1949, and reached 160.27 billion cubic meters in 2018, an increase of 22894.7 times, with an average annual growth rate of 15.7.
Electricity generation was only 4.3 billion kWh in 1949 and reached 7111.77 billion kWh in 2018, an increase of 1652.9 times and an average annual growth rate of 11.3 percent.
The "Report on Energy Development Achievements in the 70th Anniversary of the Founding of New China" shows that in the early days of the founding of New China, my country's energy production capacity was insufficient and the level was not high. In 1949, the total energy production was only 0.02 billion tons of standard coal. After 70 years of rapid development, my country's energy production has gradually grown from weak to strong, and its production capacity and level have been greatly improved. It has become the world's largest energy producer, and has basically formed a multi-wheel drive of coal, oil, gas, and renewable energy. The energy production system has given full play to a solid and powerful basic guarantee role.
The constantly refreshing and changing figures not only meet the growing life needs of the public, but also provide an inexhaustible "power" for the rapid progress of China's economic train ".
After rapid jumps, China has moved from the dilemma of poor and weak energy supply to a well-deserved "energy power": the world's largest energy producer and the world's largest energy consumer.
From a serious shortage to a strong guarantee, this is not only the hard-won achievement of China's energy industry, but also the confidence of China's economic development in the future.
From "One Coal" to "Clean Development":
Highlight the energy responsibility of big countries
In people's memory, as early as 60 years ago, cooking, heating, train driving-all with coal. Indeed, in the early days of the founding of New China, China's coal consumption accounted for more than 90% of the total primary energy consumption, and China's economy is an out-and-out "coal economy".
But now, the situation has changed dramatically: coal has gradually faded out of the daily life of residents, and the transportation power is basically invisible. Instead, another colorful picture of life: electric cars, solar and wind power, gas stoves, electric heating?
Not long ago, on August 8, Sun Haoran, who grew up in Tianjin, came to Taiyuan for the first time on the occasion of the second National Youth Games held in Shanxi. "In my imagination, Shanxi is full of places with broken mountains and serious pollution. Unexpectedly, Taiyuan still has a natural water track with excellent water quality." Sun Haoran said. In fact, at this sports meeting, a sports field in Xishan, Taiyuan was transformed from the fly ash warehouse of the power plant. From urban pollution sources to sports and leisure venues, this change is admirable and a microcosm of Shanxi's energy transformation. Today, Shanxi, which is heavily dependent on coal, is setting off an energy revolution and embarking on the road of green development. According to statistics from relevant departments in Shanxi, in the three years from 2016 to 2018 alone, Shanxi has withdrawn nearly 90 million tons of excess coal production capacity, and advanced coal production capacity accounts for more than 57%.
Shanxi's practice reflects precisely the adjustment and optimization of China's energy structure.
According to data from the National Bureau of Statistics, in the early days of the founding of New China, my country's raw coal accounted for as much as 96.3 percent of total energy production, while other varieties such as crude oil accounted for only 0.7 percent, and hydropower accounted for 3 percent.
By 2018, the proportion of raw coal in total energy production has dropped to 69.3 per cent; the proportion of crude oil has steadily increased to a high of 24.8 per cent in 1976 and then gradually declined to 7.2 per cent in 2018; natural gas has increased from a low of 0.1 per cent in 1957 to a high of 5.5 per cent in 2018; primary electricity and other energy sources have increased from 3.0 per cent in 1949 to a high of 18.0 per cent in 2018.
Compared with traditional energy, in recent years, China's rapid development of clean energy is undoubtedly more meaningful:
In 2018, China's nuclear power generation was 286.511 billion kWh, accounting for about 4.22 percent of the country's cumulative power generation.
In 2018, China's nuclear power generation increased by 15.78 compared with 2017, accounting for 15.83 percent of non-fossil energy generation.
In 2018, China's wind power generation 366 billion kWh, accounting for 5.2 of the total power generation, an increase of 0.4 percentage points over 2017.
In 2018, the national photovoltaic power generation 177.5 billion kWh, an increase of 50% year-on-year.
In 2018, clean energy (including non-fossil energy and natural gas) accounted for about 22.2 percent of China's total primary energy consumption.
These are the epitome of China's energy structure adjustment. The person in charge of the National Energy Administration said: There are various uncertain factors in the future energy situation, but China's direction of optimizing the energy structure and transforming the development mode will never change.
Just as gasoline and electricity are the driving force for cars, economic development cannot be separated from the driving force of energy. Every energy revolution in history will bring a wave of industrial revolution, and countries that seize the opportunity of a new round of energy and industrial revolution will rise, just as peat is to the Netherlands, coal is to Britain, and oil is to the United States. At a time when the supply of fossil energy is increasingly scarce and the use of fossil energy is facing strict carbon constraints, the new energy revolution has begun. In this wave of energy revolution and the industrial revolution triggered by it, China is undoubtedly ahead.
energy science and technology innovation capacity:
From "running" to "running" to "leading"
In Shangwan Town, Ejinhuoluo Banner, Ordos, Inner Mongolia, there is a large chemical plant covering an area of more than 3000 acres. Pulverized coal finer than flour enters the pipeline and reactor. After more than 20 hours of high temperature, high pressure and hydrogenation, the coal becomes high-end oil products such as diesel and naphtha as clear as mineral water. This is the direct liquefied oil production line of million tons of coal in Ordos Coal to Oil Branch of National Energy Group.
Wang established, general manager of Ordos coal-to-liquid branch, said proudly: "This production line can be said to be the country's most important weapon, China is rich in coal, lack of oil, less gas, coal into oil, carrying China's energy security strategy. So far, China is the only country in the world that has mastered the key technology of direct liquefaction of million tons of coal."
After years of development, at present, China's energy science and technology innovation capability has gone from "following" and "running side by side" to "leading" in part ".
In the energy field that affects the future and is full of competition, the level of science and technology not only represents the current strength, but also indicates the future potential.
In the 70 years since the founding of New China, a series of eye-catching scientific and technological achievements have continued to emerge in the field of China's energy industry: progress has been made in the in-depth exploration of fossil energy resources and the application of green mining technology, and the exploration and development of shale gas, large-scale natural gas liquefaction, etc. Major breakthroughs have been made in research and development of research and equipment. At the same time, new energy and renewable energy technologies have gradually matured, the world's largest 800000-kilowatt hydropower unit has been built and put into operation, a complete wind power manufacturing system has been basically established, and the independent innovation capabilities of photovoltaic manufacturing technology have been greatly improved. Important breakthroughs have been made in ocean energy technology, and the third-generation nuclear power AP1000 design and equipment manufacturing technology have been basically mastered.
The scientific and technological strength of the power industry has shown a trend of rapid progress: China has fully mastered the world's most advanced core technology for UHV construction, and has built the world's highest voltage level and largest capacity AC and DC transmission project; built a complete electric vehicle and power lithium battery industry Chain; ultra-supercritical units have been independently developed, and the number and total capacity of million-kilowatt ultra-supercritical units put into operation rank first in the world.
In addition, China has established an internationally competitive energy equipment technology industry in some areas, and some energy technologies have even reached the world's leading level, providing strong support for ensuring national energy security and promoting energy clean and low-carbon transformation.
The successful test mining of natural gas hydrate in the sea area, the independent third-generation nuclear power technology "Hualong One" to the world, and the creation of a new era of world hydropower million-kilowatt-class hydroelectric generating units? These scientific and technological innovations recorded in the history of world energy are all marked by the proud Chinese brand, all demonstrating China's position and weight in the global energy field.
Supported by the continuous progress of energy technology innovation capabilities, my country's GDP has grown rapidly from 367.9 billion yuan in 1978 to 82.48 trillion yuan in 2017, an increase of 34.5 times, with an average annual growth rate of 9.5.
It is foreseeable that with the opening of the door of the "combustible ice era" and breakthroughs in more core technologies, my country's core competitiveness in the world's energy field will gradually increase, and the right to speak will be further strengthened. (From China Energy Network)
