Oil will always run out one day. To save for a rainy day, mankind in order to solve the energy problem is looking for alternatives. With the development of science and technology, the energy structure is changing. Renewable energy is gradually coming into view, wind energy, water energy, geothermal energy, solar energy and other clean energy is being developed and utilized, oil, coal and other fossil energy use ratio is reduced year by year. New energy sources such as combustible ice, oil shale and shale gas will also be exploited in large quantities in the near future, and may even replace oil. In recent years, China's atomic energy technology has developed rapidly. The construction of the Hualong II nuclear power unit, which provides a guarantee for the safety of nuclear power generation, is bound to be vigorously promoted. The nuclear fission small sun developed by China University of Science and Technology can extract deuterium and tritium from seawater, and if popularized, there will be an inexhaustible source of energy for human use. The use of oil will be reduced year by year, and eventually stop using it.
Oil is a natural resource. Human use of oil has a long history, China is the first country to discover and use oil. Petroleum from the ancient zezhong fire, to modern metallurgy, the use of internal combustion engines, and even through the petroleum products derived from a variety of raw materials, including textiles, biopharmaceuticals, rubber, polymers, and other industries can be seen in the figure of petroleum. Including the production of non-woven fabrics for face masks during the new Crown Pneumonia epidemic, the polypropylene needed is extracted from petroleum. So oil resources are widely used in a variety of industries, fields, and human life is closely related.
Then the development of science and technology has brought about innovations, and the ability of human beings to transform nature has continued to improve, and science and technology have brought more and more far-reaching impact on human life. But the development is endless, the nature of human transformation of the objective world has not changed, oil as a natural resource, is also the object of transformation. From this point of view, human beings will not be far away from the day of oil, but will be closer. But the method of use and the degree of utilization will be more scientific rather than abusive. There is no contradiction between the correct use and protection of oil resources.
In the field of energy, mankind through the effective transformation of solar energy, wind energy, tidal energy, geothermal resources, nuclear energy, and hydrogen energy through the gradual development of synthetic technology, through science and technology to effectively transform these natural resources into new energy, to replace the non-renewable resources of oil is facing the depletion of the bottleneck to provide different solutions to the path. Promoting the effective transformation of other renewable energies is a scientific way of preserving oil resources. It will leave a legacy of well-being for future generations. But it does not mean abandoning the use of oil.
From the production of raw materials, petroleum applications also have a broad stage, far from the manufacture of chemical products, close to the life of the goods everywhere, nowhere to be seen in its figure, can be said to be closely related to life and work. No matter from what point of view to evaluate the oil, we can not refuse its existence. It is like a god, always take care of our quality of life.
The effective use of oil for the development of human civilization to provide broad space, through the effective and rational use of natural resources, human wings to fly farther. Oil was used in ancient times, and is still being used, and should be used again in the future. The only difference is that through the productivity of science and technology, different driving forces have been generated, so that the oil is playing its due value of existence.
With the development of technology, the day when new energy can replace oil is not far away.
Hello, I am Shuanghuan CNC, glad to answer your question.
Humans are not far from the day when we don't need to use oil, and it is possible to realize it within a hundred years. If you and I can live to be more than a hundred years old, we can definitely see it, and we can think about it from several aspects.
One, the Earth's oil reserves are limited.
According to the American Petroleum Institute's estimates, there are less than two trillion barrels of crude oil reserves on the planet that can be exploited by human beings for less than 95 years. And according to the global oil consumption now, in 2050 before the oil will be depleted, after the days of energy can only burn coal and minerals. So in our generation, we need to use energy sparingly, and in our children's and grandchildren's generation, we are afraid that there will be no energy available.
The development of new energy sources. We have realized that energy will run out of the day, in our generation we have to leave wealth and energy for future generations, such as solar energy, electric cars instead of fuel cars, wind power generation, natural gas development, shale oil development, combustible ice development, etc., are for no oil to find a good way out. Oil can be used sparingly, can not be exploited do not exploit, like the United States is very cunning, the domestic large tracts of oil fields are always not exploited, every day thinking about how to grab the Middle East oil, and so on other people's homes run out of oil, their own home pots and bowls are all oil.
Three, take the road of sustainable development. The country and even the world are advocating the path of sustainable development, in the development of the same time to reduce the earth's pollution, saving environmental protection. Instead of sacrificing the environment for the country's rapid development and overuse of the Earth's resources, people are rich, the country is also developed, but our planet our home has been devastated, full of holes, industrial waste heaps, garbage into the mountains, which is not our hope of home, but hell on earth.
Fourth, at the end of the day, maybe people think they don't care, it doesn't matter to them.
I can't even afford to buy a car right now, but I'm still worried about oil. The oil is not only a source of energy for cars, but also for many industries, machinery, healthcare, transportation, communications, clothing, and so on, all of which are interconnected. If there is no oil, we may still go back to the Stone Age and live a primitive life.
Humans can certainly develop alternative sources of energy to oil in the future, but it is unlikely in the short term.Oil is the blood that guarantees production and has always been the lifeblood of every country. But because several major oil-producing regions in the international arena have joined forces and then control this lifeline, so some countries are studying how to wind power, hydropower, nuclear power, especially solar power instead of oil, as far as possible to get rid of the dependence on the oil countries. But this requires a very difficult process.
Why is oil so hard to get rid of dependence?As a fuel class. Even if the new energy family car can be popularized, in terms of load, in terms of construction machinery vehicles, in many ways can not be separated from oil.
Oil in the chemical use is also difficult to replace, because the cracking of crude oil will become a lot of basic raw materials, such as ethylene, toluene and so on, these basic raw materials and then synthesized into a series of products, such as synthetic leather, fibers, chemical fertilizers, plastics, synthetic rubber, coatings, adhesives, and so on, equal to say that our food, clothing, housing, and transportation can not be separated from the oil.
With the acceleration of technological breakthroughs, the development of new energy technologies that are more practical, less dependent on oil, and more cost-effective, should also be accelerated.
One oil price fluctuation is enough to trigger an economic crisis, so the world is accelerating its research and development of clean energy.
It is worthwhile to be vigilant that once our country does not have independent mastery of the new technology, then, like oil, will still be controlled by foreign countries.
Accelerating the protection of science and technology personnel is to protect ourselves.
Not far
It's possible to be independent of petroleum energy, but it's probably not until the 22nd century.
Far away.
You can see that countries around the world have been fighting over oil for a long time
With the development of human science and technology, it's not far from the day when we leave oil, it's not only that we can't leave it, but that we should continue to develop and utilize it.
Here only on behalf of personal views and perspectives to talk about some of the things related to oil:
One oil as energy
1 Now known energy sources, there are the following types:
Physical energy, chemical energy, nuclear physical energy, energy, antimatter energy. Separate explanations:
Physical energy: before and after the reaction is only a change in the position of the object and its own form of change, the release of energy is relatively small; with the later kinetic energy weapons are different.
Chemical energy: After the reaction, a new substance is created, but the new substance is still composed of the relevant elements of the substance before the reaction; the release of energy is larger.
Nuclear energy: the reaction creates a new substance, which is really new and has completely different elemental properties from the substance before the reaction; the energy released is huge.
Antimatter energy: nothing is created after the reaction, it is really "nothing", and the energy released is very large. (E = 1/2mv?, v is the speed of light)
2 Throughout the history of the development of human society, is the gradual escalation in the use of energy in the history; from the performance of these historical inference, the whole process of the development of human society, to the present only in the juvenile stage.
Human society from the history of written records, only a few thousand years; the use of energy is only physical energy to support the industry in this period is very little, hunting agriculture and animal husbandry development is the main body.
3 Oil and coal development and utilization
The first industrial revolution, mechanized production instead of manual operation, the invention and use of the steam engine, the use of coal as a chemical energy source provides prospects; the second industrial revolution, the realization of electrified production, oil and coal as the basis of the power of energy began to comprehensively serve mankind; the third industrial revolution, the arrival of automation technology, but also the The third industrial revolution, the advent of automation technology, also oil coal and other chemical energy as the basis for a wide range of large-scale applications in agriculture, industry, defense and other fields, greatly stimulating the overall development of human society.

Second, oil as an industrial raw material
Oil in its smelting and processing process, as a power energy has been widely used; in its by-products and derivatives of the development and utilization is still underway, in people's food, clothing, housing, transportation, medical care and health, industrial and agricultural production and national defense construction has a wide range of uses in some of the cutting-edge aspects of science and technology are also being developed and utilized. development and utilization.
At present, the human society really want to leave the oil coal, its other resources can be utilized is certainly overstretched. So, oil and coal will not be abandoned for a long time; on the contrary, people will rely on oil and coal, and their derivatives, for industrial raw materials.

Third, the use of oil and coal in the off-topic
People are always worried that millions of years of biological crustal changes in the formation of oil, humans in less than 200 years will be consumed.
In fact, there is no need to worry, the conversion of inorganic salts into organic matter is also the effective range of nature's ability to change the material; nature's ability to change this change may exceed people's imagination a lot of very wide.
The limited consumption of materials on the Earth's surface may also have some natural links to human self-preservation, that is, the material energy in nature is originally for other material animals or humans to consume in a limited way; if it is never used, it will also seriously affect its own progress, and may evolve into a disaster for human beings.
Forest fires
To cite a few extreme examples for reference:
1 Forest fires
Today, the world's people with brains generally believe that extensive greening is the most advantageous means of protecting nature and themselves, so cutting down trees is prohibited in order to protect the ecosystem.
The forest fires in the United States, Brazil, Australia, and China remind us that it is also important to have a reasonable density of forest trees, or artificial intercropping, and that it is necessary to cut away excess trees and have a reasonable area of fire distance. Of course, slash and burn is absolutely not allowed.
2 Oil and coal
"Journey to the West" in the Flaming Mountains, estimated with the spontaneous combustion of coal is very much linked to the exposed coal in the ground, after a long time shall not be developed and used, there will be spontaneous combustion formation, and once they are spontaneous combustion on the environment of the degree of destruction and we use the equivalent of coal to generate electricity, why we can not be used to generate electricity from fossil fuels.
The use of oil is also similar to the role of coal. If we humans don't exploit it, then it will naturally be used to destroy it, and that process is equivalent to the human equivalent of utilizing it.
It is said that the extinctions in history were the result of planetary impacts; in fact, there is another force that could have caused this: the global ravages of fire. The cause of these fires is methane, a petroleum gas.
Sewers, swamps, and surface seepage in oil-rich places can produce large quantities of methane gas, and there is a country in the CIS that has a perennial gas flare-up, which is indicative of the magnitude of this gas; the combustible ice in the South China Sea is also a methane hydrate crystallization. If there are crustal shifts, it could also tumble to the surface in a chaotic manner.
And if these gases are not consumed and utilized artificially, after a long geologic time, they will burn up in the air on a large scale, and the resulting excessively low pressure will roll up the seawater, which is estimated to cause a major extinction of the Earth's organisms.
In summary, human beings should correspond to their development activities in accordance with the laws of nature, and anything too extreme is undesirable.
Full respect for nature, in accordance with the objective law, can be sustainable development and progress.
To say that not far away, to say that not close, mankind to completely get rid of the dependence on oil resources, mainly depends on the global human spiritual awakening awakening degree, this civilization is whether the civilization for the next alternative? Will mankind be able to get out of the closed space of dualistic understanding? If in the near future, global humanity is fortunate enough to have a great awakening! The overall level of consciousness and soul of the global human race will be raised, then the magnetic civilization will meet unexpectedly, and only at this time can we human beings talk about truly getting rid of our dependence on the earth's coal and petroleum energy. Otherwise, according to the ugly consciousness of modern civilization development, human beings can't talk about getting rid of the dependence on coal and oil? Can human beings sustain this civilization? It is still a huge unknown!
