What is the danger of energy crisis?

A series of problems such as transportation, finance, industry and commerce caused by the exhaustion of traditional fossil energy such as oil and coal and the failure to establish a new energy production and supply system are collectively called energy crisis. According to the general estimation of economists and scientists, by the middle of this century, that is, around 2050, oil resources will be exhausted and its price will rise to a high level that is not suitable for popularization and application. If the new energy system is not established, the energy crisis will sweep across the world, especially in developed countries in Europe and America that rely heavily on oil resources. The most serious state is that the industry has shrunk dramatically, and even war has been triggered by seizing the remaining oil resources. In order to avoid the above difficulties, the United States, Canada, Japan and the European Union are actively developing renewable new energy sources such as solar energy, wind energy and ocean energy (including tidal energy and wave energy), or turning their attention to new fossil energy sources such as submarine combustible ice (hydrated natural gas). At the same time, hydrogen, methanol and other fuels, as substitutes for gasoline and diesel, have also received extensive attention. At present, the hydrogen fuel cell electric vehicle, which is being studied enthusiastically at home and abroad, is a typical representative of this kind of energy intermediary application. Energy is the most basic driving force for the development and economic growth of the whole world and the foundation of human survival. Since the industrial revolution, energy security has emerged. 19 13, when the British navy began to use oil instead of coal as its power, Churchill, then an admiral, put forward the principle of "never relying on only one oil, one process, one country and one oil field", which is still not outdated. With the increasing demand for energy in human society, energy security is gradually closely linked with political and economic security. In the two world wars, energy has become an important factor affecting the outcome of the war and determining the fate of the country. French Prime Minister clemenceau once said, "A drop of oil is equivalent to a drop of blood of our soldiers". It can be seen that the importance of energy security has been widely recognized by the international community at that time. The two oil crises that broke out in 1970s greatly expanded the connotation of energy security. In particular, the International Energy Agency (IEA) established in 1974 formally put forward the concept of energy security with stable oil supply and price as its core, and western countries have also formulated energy policies with energy supply security as its core. In the following two decades, with the support of stable energy supply, the world economy has achieved tremendous growth. However, while enjoying the benefits of economic development and scientific and technological progress brought by energy, mankind has also encountered a series of inevitable energy security challenges. Energy shortage, resource competition and environmental pollution caused by excessive use of energy threaten the survival and development of mankind. At present, some conventional energy reserves in the world can only last for half a century (such as oil) and can meet the needs of human survival for one or two centuries at most (such as coal). Today, the population of the world has exceeded 6 billion, more than twice that of the end of last century, and the energy consumption has increased by 16 times according to statistics. No matter how many people talk about "saving" and "using solar energy" or "drilling more oil wells or gas wells" or "discovering more and larger coal fields", the supply of energy can't keep up with the human demand for energy. At present, the world's energy consumption is dominated by fossil resources, among which a few countries such as China are dominated by coal, and most other countries are dominated by oil and natural gas. According to the current consumption, experts predict that oil and natural gas can only last less than half a century at most, and coal can only last for one or two centuries. Therefore, no matter what kind of conventional energy structure, the energy crisis facing mankind is becoming more and more serious. At present, the energy security problem facing the world presents new features and changes that are obviously different from the previous oil crisis. It is not only an energy supply security issue, but also a comprehensive risk and threat including energy supply, energy demand, energy price, energy transportation, energy use and other security issues. China is the largest developing country in the world, and it is also a big producer and consumer of energy. Energy output is second only to the United States and Russia, ranking third in the world; Basic energy consumption accounts for L/ 10 of the world's total consumption, ranking second in the world after the United States. China is also a country with coal as the main energy source, and the contradiction between economic development and environmental pollution is more prominent. In recent years, energy security has increasingly become the focus of national life and even the whole society, and has increasingly become a hidden danger of China's strategic security and a bottleneck restricting the sustainable development of economy and society. Since 1990s, the sustained and rapid economic development in China has led to a sharp rise in energy consumption. Since 1993, China has changed from a net exporter of energy to a net importer. The total energy consumption has exceeded the total supply, and the external dependence of energy demand has risen rapidly. There are gaps in energy sources such as coal, electricity, oil and natural gas in China. Among them, the huge increase in oil demand and the structural contradictions caused by it have increasingly become the biggest problem facing China's energy security. In the foreseeable future, the number of automobiles will not be greatly reduced, but the oil crisis will indeed have a certain impact on the automobile industry, such as developing new automobiles (such as hybrid, fuel cell, hydrogen power, solar energy, etc.). Reduce dependence on oil, reduce unnecessary car use (mainly private cars) to save fuel, etc. But on the whole, there is no need to worry about the reduction of cars.

Law of Conservation of Energy: Energy will neither be generated nor disappear, it will only be transformed from one form to another.

Plants absorb the energy of the sun and grow. Animals eat plants to replenish energy. At the same time, animal waste is also a fertilizer for plants. Plants absorb carbon dioxide and release oxygen, while animals absorb oxygen and release carbon dioxide. Therefore, plants and animals subsidize each other, and they depend on each other to survive.

So because of the energy of the sun, there will be plants and animals, and all the energy on the earth comes from the sun.

I suggest that the state encourage farmers to farm scientifically, reduce the waste of resources, fertilize plants with more animal manure, and then use plants that cannot be eaten by people as animal feed to circulate energy between plants and animals. Try to keep the grain for a long time, and don't let it rot and deteriorate too quickly. Use more renewable energy such as solar energy, wind energy and biogas to reduce pollution. Family planning, maintaining a balanced relationship between plants and animals. People should not overeat, resulting in overnutrition, easy to get high blood pressure, hyperlipidemia, hyperglycemia, high cholesterol and other diseases, and maintain a healthy weight to live longer.
