The sustainable development of energy demand
In 1987, the World Commission on environment and development entitled "our common future" (OurCo + onFutMre) report, first expounded the "sustainable development" (SustaiMbleDevel. The concept of Pment), it includes the needs of present and future generations, national sovereignty, international justice, natural resources, ecological carrying capacity, is an important content of environment and development. Sustainable development is from the perspective of environmental protection to promote maintain the progress and development of human society, it calls for people to increase production at the same time, we must pay attention to the protection and improvement of ecological environment. Sustainable development is a related to economic, social, cultural, technological and natural environment of the comprehensive concept, three aspects of sustainable development, including natural resources and the ecological environment and economic and social sustainable development. Sustainable development is the sustainable use of natural resources and a good ecological environment as the basis; two is the economic sustainable development as the premise; three is to seek the comprehensive progress of society as the goal. Sustainable development is not only an economic problem, but also is not only a social or ecological problems, but is a complex of the mutual influence of the three. Put forward in the concept of sustainable development, has aroused great interest and attention of scholars around the world, so that the theory of sustainable development in the past twenty years has been the rapid development and improvement, has formed the theoretical system of sustainable development of complete. The theory of sustainable development makes people gradually realize that the past development is not sustainable, at least for not enough, so it is not desirable, the world only development road of the choice is to take the road of sustainable development. Put forward the concept of sustainable development, the common identity of all countries with different economic levels and different culture background. Sustainable development is the developing and developed countries can achieve the goal, the developing countries are actively engaged in the practice of sustainable development is also an important reason for the theory of sustainable development all over the world.
In the process of rapid economic development, energy consumption will increase by a large margin, but also exacerbated environmental pollution and environmental protection pressure. Energy is an essential material basis for human survival and development, which restricted the development of human society in the 'extent. If the use of unreasonable energy, will damage the environment, and even a threat to the survival of human beings. The strategy of sustainable development calls for the establishment of energy for sustainable development support system and does not harm the environment energy use. With the development of world economy and the increase of population, human demand for energy is more and more big. Under normal circumstances, the greater energy consumption, GDP is high, the energy shortage will affect the development of national economy. As in the 1974 world energy crisis, energy shortage USA 1.16 x lo. T standard coal, GDP fell by $93000000000; the Japanese energy shortage 6 x 10 't of standard coal, GDP fell by $48500000000. Generally speaking, the economic loss caused by the shortage of energy about the value of its energy from 20 to 60 times. Therefore, no matter which country any time, if you want to speed up the development of national economy, we must ensure that the corresponding increase in energy consumption, to sustainable economic development, we must take the road of energy production and consumption and trade sustainable.
In the rapid growth of economy, the energy industry is facing double pressure of economic growth with environmental protection. Economic growth leads to the increase of energy consumption, and in use of energy conversion process, the pollution of the environment. In the whole world, and before the middle of the twenty-first Century, fossil fuels will still occupy a major proportion in primary energy. In the use of fossil fuels, greenhouse gas each year about 2 x 10 "on the T, the concentration of carbon dioxide in the atmosphere every year and other greenhouse gases continue to rise. Large amounts of greenhouse gases resulting rise in global temperatures, and caused a series of environmental problems. At present, energy demand in developing countries is growing at an annual rate of 7% in developed countries, the annual energy growth rate is about 3%. Because of the population in developing countries is three times more than the population of developed countries, so developing countries the potential demand for energy is industrialized countries several fossil fuels as non renewable energy sources, in order to guarantee the sustainable development of economy, in improving the fossil fuel energy use string at the same time to develop and promote the application of new energy and renewable energy, to meet the human sustainable the growth in demand for energy. Only human beings still rely on the ability of science and technology, scientific spirit and rational to ensure global, human survival and sustainable development, in order to make the population, crab source, energy, environment and development elements constitute towards rational direction changes, thus forming regions and generations; sustainable development. |
