Energy is an important material foundation for the development of national economy, because of the need to develop means to change the original appearance, also is to change, and everything in the world changes are accompanied by energy consumption. Hence the need for energy.
In modern industrial production, any production machinery and transport operation, need a mechanical power enough to guarantee, no energy (power), any advanced production equipment and transportation tools will become a pile of scrap metal. A country's industrial and agricultural production is more developed, more products are produced, it energy consumption is more and more, so the development level and speed of the energy industry is a measure of a country's economic strength - 'vital signs. Especially for some consume a large amount of primary energy departments such as metallurgy, chemical industry, electric power, etc., especially
Explicit Twilight
In modern agriculture, greatly the improvement of agricultural production needs to consume large amounts of energy. Farming, irrigation, harvesting, drying, storage, transportation and so on, are required to direct consumption of energy. The use of chemical fertilizers, pesticides, herbicides, and indirect energy consumption. For example, the production of LT synthetic ammonia consume the equivalent of 2; a 3.ot standard coal energy, the production of 1t pesticide average equivalent to L 5T of standard coal energy. The United States in 1945 - 1975, the average per ton of grain's energy consumption by the equivalent of 20k8 of standard coal increased to quite dry 67kx standard coal, but the yield per acre by flat 204kg increases to 486k8. that is to say, the yield increased. 1.4 times, while energy consumption has increased Ding 2.4 times. Therefore, if there is not enough fuel and dynamic
Power is provided, the agricultural production of modernization cannot be. As the degree of modernization of agriculture of our country continues to improve, agricultural mechanization, electrification is rapid development, the need for chemical fertilizers, pesticides, herbicides, are more and more, not the development of the energy industry to be guaranteed
Card, the realization of agricultural modernization is an empty word.
In the modern transportation, coal, petroleum, without power, no matter is the train, car, ship, or aircraft, car, can not be running, why talk about the transport of goods and people. Without the development of the energy industry, transportation industry could not develop.
In the modern national defense, their power sources, in addition to nuclear energy, currently there is no other energy to replace oil. The use of modern national defense transportation tools and weapons, such as automobile, motorcycle tank, etc., all need oil. Is the jet aircraft, rocket, missile modernization, also need to consume a large amount of oil resources. So to realize the modernization of national defense, must also be the development of energy industry first.
With the improvement of people's living standard, daily life energy consumption in the proportion is increasing. In our life, gas, TV, refrigerator, air conditioning, heating, which is not far from the energy. In the developed capitalist countries, civil consumption of energy to total energy consumption countries with T: 20 pecks, while only 10% in our country, of course, these countries the people's standard of living is much higher than in China.
The development history of the human society, the industrial revolution or the rapid development and wide application of energy is to develop new for the pilot.
The first industrial revolution is due to the widespread use of coal and petroleum. Due to the use of coal. The steam engine is widely used in industry, the production gradually realize mechanization and semi-mechanization, greatly improve plant productivity. Due to the use of oil, the engine, the power machine with higher efficiency, smaller volume, higher power, can be miniaturized. Especially with the development of transportation, the automobile, aircraft, if there is no oil, coal is used to make airplane power source is unthinkable.

First: big turning point is widely used in.19 century 70's of electricity, steam turbine and generator, and promote the rapid development of power industry. Power applications is a great revolution in energy science and technology, it makes the thermal energy of the fuel is converted into electrical energy, and then used in the production of electric energy is called. "The universal form of" energy, it is convenient for centralized supply, easy dispersion, with transmission quickly and have low consumption, transportation, use, management are very convenient, and can be transformed into various forms of energy. Lenin has long said, "communism is the Soviet power plus electrification", importance a visible. We are now in a will, no electrical products, equipment and components, our life always cannot do without electricity. Due to the widespread use of electricity, will bring human beings into a highly civilized society.
The third major turning point is greatly increased oil consumption has driven the rapid development of the world economy. This is because the oil and coal compared with many advantages: one is the oil exploration and mining easy. Build a million tons of coal, in 10 years time and a lot of money, but the oil easier much, much less investment. Secondly, oil is used as fuel, high heat value, convenient use, convenient transportation and clean. Thirdly, the oil can be used as industrial raw materials, with oil as raw material for industrial products have more than five thousand kinds. People wear, hold, use, many of which are petroleum products, or even to eat the (Medicine) also have the petroleum products. The above chemical industrial raw material 70% capitalist countries for oil, Britain and Japan 80%, West Germany 93%, the United States has reached 9. The fourth is the oil can be processed into high-grade lubricating oil, provides a condition for power machinery to improve the power of its unit weight
