    Chapter 89 Characteristics of Hydropower Energy

    Through this period of study with Song Bolin, Liu Shuangxi became very interested in Mathematical Olympiad. He did not hope to achieve brilliant results. What was attractive was that there were indeed many interesting things in it.  If something hadn't happened in the capital, he would have been reluctant to put aside the exam he was preparing for and rush back.

    The cause of the matter was that in early June, after reviewing the preliminary calculation of the scale of capital construction of the Seventh Five-Year Plan proposed by the State Planning Commission and the report of the Ministry of Finance on financial issues, Mr. Deng made relevant instructions: "The current situation is that there are too many funds.  Scattered, how can we live like this? Some things must be stopped, which may require some losses. We would rather lose some than stop and focus on the key points. If we want to be able to carry out the next twenty years, we must not focus on the key points now.  Especially key projects such as energy, transportation, and communications. If we don't do it now, we won't be able to do other things in the future. Now I'm worried about whether the energy in this plan is enough? Especially whether the electricity is enough? If electricity is quadrupled by the end of this century, electricity will only be enough.  Can it be increased by one point or three times? Now it is not only industrial electricity, but also domestic electricity. Many people have washing machines and refrigerators at home. Rural areas need to use electricity to replace firewood. This cannot be solved by quadrupling.  Problem. Be more ruthless, this is related to the speed of development in the future" Shortly after giving this instruction, the relevant departments' proposal for the construction of the Three Gorges Hydropower Station was placed on the desk. Mr. Deng immediately remembered that Liu Dong had told him some time ago  As mentioned before, when Liu Shuangxi was in Xiangjiang, he suggested that Li Chaoren invest in this project, and the old man summoned him back.

    The focus of the conversation was of course on electricity. Not long after Liu Shuangxi arrived at this inconspicuous little courtyard with gray walls and gray tiles on the back street of Jingshan, Mr. Deng said directly: "You have also seen the relevant documents. Our country's electricity is not bad for the time being.  Wealthy, but judging from the current development trend, there will definitely be a huge gap. Since you and Li Chaoren have suggested investing in the Three Gorges Project, tell me the reasons for your idea."

    Liu Shuangxi felt very relaxed every time he came to this small courtyard of the Deng Family to chat with the elderly. After all, the environment here was not as tense as in the Deng Family Courtyard. However, the topic today covered a wide range of topics. He organized his words and said: "In Deng's family, Grandpa, you have already mentioned in your previous conversation that there may be a huge gap in electricity in the future. LetĄŻs first take a look at the current power generation model. First of all, letĄŻs talk about thermal power generation, which occupies the largest market share. As the name suggests, it uses coal, oil, and natural gas. The heat energy generated when solid, liquid, and gaseous fuels are burned is converted into electrical energy through a power generation device. Although it is the most stable energy source, it is not affected by climate, the output is controllable, and it can provide continuous energy supply. However, its disadvantages The impact is also huge. For example, the burning of coal will release a large amount of acid gases such as sulfur dioxide, which will cause an increase in acid rain. The fly ash near the power plant will also cause adverse effects on people's lives and the growth of plants. As for the development of thermal power, Fundamentally, my countryĄŻs current proven remaining reserves and exploitable years of conventional energy are very limited. Among them, the remaining reserves and exploitable years of fossil energy, such as coal, are only over a hundred years old, oil is less than forty years old, only half of the worldĄŻs reserve-production ratio, and natural gasĄŻs The reserves are only eighty years old, so it can be said that high-quality energy is very scarce.Ą±

    Deng Lao sighed and said: "It is said that China has a vast land and rich resources, but in fact, after truly understanding it, there are not many resources for our development, especially these non-renewable resources, which will be consumed sooner or later."

    Liu Shuangxi said: "Compared with thermal power, hydropower is a clean and renewable energy source, and it is also the second largest energy resource after coal. According to statistics from a census in the past few years, my country's current theoretical reserves of a single river are 087.6 million kwĄ€ There are 3019 rivers above h/a, with a total theoretical reserve of 5.7 trillion kwĄ€h/a; after adding some smaller rivers, the total is 5.92 trillion kwĄ€h/a (water energy resources in Baodao Province are not counted ), ranking first in the world. According to statistics, there are more than 11,000 developable hydropower stations with a single station installed capacity of 500kw and above, with a total installed capacity of 378.53 million kw and a multi-year average annual power generation of 1.9233 billion kwĄ€h. All major regions and regions across the country Based on the theoretical reserves of the water system and the distribution of technically exploitable resources, it is initially estimated that the economically exploitable resources are an installed capacity of 290 million kw and a multi-year average annual power generation of 1.26 trillion kwĄ€h."

    After the data came out, Mr. Deng said with a smile: "It seems that you are satisfied with your preparations. In this case, tell me about the characteristics of hydropower energy in detail."

    Liu Shuangxi really didnĄŻt prepare it specially. All this information was seen in the political research office in his previous life. The report on ChinaĄŻs water conservancy development made detailed records. He excerpted a part of the report and said: "Hydropower energy follows the natural environment.  It can be repeatedly regenerated according to the hydrological cycle and can be used by humans over and over again. People often use "inexhaustible, inexhaustible" to vividly describe the renewable nature of hydropower energy. Hydropower energy does not consume fuel during production and operation.  Excretion of harmful substances, its management and operation costs, power generation costs and impact on the environment are much lower than thermal power generation. It is a low-cost green energy. Hydropower energy has good regulation performance and fast start-up, and is widely used in the power grid.It plays the role of peak shaving during operation, which is fast and effective. It can reduce the power supply loss of the power grid under extraordinary circumstances and accidents and ensure the safety of power supply.  Hydropower energy and mineral energy both belong to resource primary energy. After being converted into electrical energy, it is called secondary energy. Hydropower energy development is the simultaneous completion of primary energy development and secondary energy production. It has both primary energy construction and secondary energy construction.  Dual function; no primary energy mineral mining, transportation and storage costs are required, greatly reducing fuel costs.  Hydropower development and construction of reservoirs will change the ecological environment of local areas. On the one hand, it needs to submerge part of the land and cause the relocation of immigrants. On the other hand, it can repair the microclimate of the area and form a new water ecological environment, which is conducive to the survival of organisms and is beneficial to the survival of organisms.  Humans carry out flood control, irrigation, tourism and development of shipping.  "

    Mr. Deng said: "Experts do believe that the Three Gorges Project you mentioned has many disadvantages, such as the impact of project construction on the environment, the test of our country's financial resources, the loss of intangible and tangible assets, and the possibility of future wars.  Becoming a key target of attack, etc., how do you feel about this?"

    Liu Shuangxi said: "The benefits of the Three Gorges Project are mainly concentrated in flood control, power generation and shipping. If the project is built, the primary effect will be to generate a huge adjustment storage capacity, which can very effectively improve the flood control standards downstream, and can also effectively  Delay river sedimentation. After the construction of the Three Gorges Dam, it can control the flood that occurs once in a century, and the flood that occurs in a thousand years ensures the safety of the middle and lower reaches. It can be said that the history of China is the history of river management. Without flood control, the country cannot be stabilized. The storage capacity of 22.1 billion refers to  The Three Gorges Reservoir has such a large capacity to block floods during the flood season. This will ensure the safety of 23 million acres of cultivated land and 15 million people in the middle and lower reaches.

    Its power generation is expected to account for 3% of the country's total annual power generation and 20% of the country's hydropower generation. In addition to bringing some fiscal revenue to the country, its benefits also solve the problem of power supply in Central China, East China, South China and other regions after the construction of the Three Gorges Dam.  The rolling river water works for the Three Gorges Hydropower Station, generates electricity, and back-regulates the shipping cascade between the Three Gorges and Gezhouba Dam, and then works for the Gezhouba Hydropower Station to generate electricity. As a result, the total annual power generation of the Three Gorges and Gezhouba Dam will reach 105 billion kWh.  If the electricity price per kilowatt hour is 0.1 yuan, the annual present value is 10.5 billion yuan; if the electricity output value is 5 yuan per kilowatt hour, the country can create an additional output value of 525 billion yuan every year; if the per capita annual output value is 10,000 yuan, 5.25 million people can be accommodated  People are unemployed.  The Three Gorges Hydropower Station is located in an important area in my country. The transmission distance to major load centers in the country is about 1,000 kilometers. It will be the center of major domestic power grids in the future.  After the power grid is connected to the Internet, it can not only complement other domestic thermal, hydro, and nuclear power plants, but also greatly improve the quality and efficiency of the power grid operation.  In addition, the annual power generation of the Three Gorges Hydropower Station after completion is equivalent to burning 50 million tons of coal. Since coal is replaced with water, 120 million tons of carbon dioxide can be avoided in the atmosphere every year.  It can also reduce acid rain caused by carbon dioxide.  This is not only an improvement for China's environment, but also meaningful for the improvement of the entire global environment.

    Ą°Also, the Three Gorges Project can effectively improve the local transportation environment. It is also a golden opportunity for development in the poorer reservoir areas.  The Yi-Chongqing River section with a total length of 660 kilometers has a large gap. There are more than 100 beach hazards, dozens of single-mileage sections, and dozens of sections where heavy-loaded freighters need towing. The annual one-way shipping capacity is less than 10 million tons.  After the construction of the Three Gorges Dam, all beach hazards, single navigation sections and towing sections will be submerged. The waterway will be much wider. The 10,000-ton fleet will be able to reach the river and the sea. Shipping costs will be greatly reduced. The annual one-way shipping capacity will exceed 50 million tons.  The formation of golden waterways across the east and west of China is very beneficial to the development and prosperity of the economy from both sides of the Yangtze River to the coastal areas.  Generally speaking, in hydropower project planning, as long as overall considerations are taken and the adverse impact on the ecological environment is reduced to a minimum, the development of the Three Gorges Hydropower Station will have more advantages than disadvantages.  "

    Liu Shuangxi paused for a while, and when Mr. Deng had finished digesting it, he continued: "As for the so-called experts' concerns about security issues, I can guarantee that in the next 40 years, only small-scale local wars will occur. The main reason is the competition for energy.  The right to speak and the purpose of military training in some Western countries. As for a large-scale war against China, or even the world, it will definitely not happen during this period. By the time a large-scale conflict occurs, the Three Gorges Project has already brought benefits to China.  ItĄŻs not a matter of a day or two.Ą±

    Hearing the statement that there would be no global war in the next half century, Deng Gong asked curiously: "You guys are really so sure. You know, none of us old men who have been fighting for a lifetime dare to do such a thing."  judgment."

    (Because I have to run for a living, the number of updates in the past two days has been poor. Lao Jiu would like to apologize. I will try my best to make up for the lack of quantity with exciting plots. I believe everyone will like it.)
