Significance of developing new energy sources

Question 1: The significance of new energy development 1. Developing new energy economy is the historical trend and inevitable choice in today's world.

In recent years, the petrochemical energy, which supported the rapid development of human civilization in the 20th century, has encountered an unprecedented crisis. In addition to the continuous reduction of its reserves, more seriously, scientific research has found that carbon dioxide gas produced after the use of petrochemical energy is discharged into the atmosphere as a greenhouse gas, which artificially causes global warming, causing people's extensive concern and thinking about the driving force for future social development. The energy strategies of many countries have an obvious policy orientation-encouraging the development of new energy, which is not only caused by the high price pressure of traditional energy products such as oil in the international market (except in extraordinary times), but also the objective need of human sustainable development. Therefore, the development of new energy sources may become the most important engine of economic growth in the future and a new economic pillar with the greatest ability to create jobs and wealth. At present, global investment in new energy sources, especially wind energy, solar energy and biomass energy, has surged. There is a kind of knowledge being formed all over the world: only by taking the lead in the new energy technology revolution can we occupy a favorable position in the future world economic structure. Especially under the background that the global economy is seriously affected by the financial crisis, some experts believe that the development and utilization of new energy will be a new round of competition hotspot in the world economy after the global financial crisis. The promotion of traditional energy and the development of new energy technologies and products will give birth to a huge market, and the new energy industry will surely become an important breakthrough for all countries in the world to cultivate new economic growth points.

Second, the development of new energy economy can provide support for sound and rapid economic development.

There are abundant new energy resources and a certain foundation for new energy development, which provide support for the development of new energy economy. At present, vigorously promoting the development of new energy economy is an important period of strategic opportunities in development. Developing new energy economy can not only open up new energy supply channels, effectively increase new energy supply, but also effectively reduce environmental pollution, which is conducive to the implementation of the strategy of building an ecological province and an environment-friendly society. Moreover, from the perspective of industrial structure adjustment, the development of new energy economy will play an important role in the adjustment of current industrial structure, economic structure and development strategy, promoting the development of a series of related industries and improving the anti-risk ability of economic operation. Cultivating the new energy industry into a characteristic industry and a new economic growth point will surely promote the sound and rapid development of Qinghai's economy and become an important way to effectively meet challenges and seize development opportunities.

Third, the general idea of cultivating new energy economy.

To cultivate new energy economy, we should focus on the development and utilization of solar energy, take the solar energy industry as the leading factor in the development of new energy economy, accelerate the development of new energy sources with mature technologies and strong market competitiveness, such as solar energy, wind energy and biogas, and increase the proportion of new energy sources in the energy structure as soon as possible; Actively promote the industrialization of new energy technologies, such as biomass energy utilization, solar power generation and wind power generation, which are basically mature in technology and have great development potential, so as to lay a solid foundation for developing and utilizing new energy on a larger scale and cultivating and expanding the new energy economy. The roadmap for cultivating new energy economy should focus on the industrial chain development of solar energy, wind energy and biomass energy, and eventually form a complete industrial chain of polysilicon purification, monocrystalline silicon drawing, polycrystalline silicon ingot, crystalline silicon slicing, solar cells, module packaging and photovoltaic technology system application in photovoltaic industry, as well as an industrial development model in which solar energy and wind energy complement each other.

Question 3: The significance of developing new energy is of great strategic significance from the perspective of sustainable economic and social development, protecting the earth's ecological environment on which human beings depend, and solving the practical energy supply for some special purposes.

① New energy is the cornerstone of the future energy of human society, and it is the alternative energy of fossil energy.

In today's world energy structure, the energy used by human beings is mainly fossil energy such as oil, natural gas and coal. From 65438 to 0997, the world's total primary energy consumption was 12 156 billion. With the development of economy, the increase of population and the improvement of social life, it is predicted that the world energy consumption will increase by 2.7% every year in the future, and the total energy consumption in the world will reach10.95 billion tce by 2020. By the end of 1996, the global recoverable reserves of oil, natural gas and coal were 1.3 trillion tce. Although new reserves may be discovered in the future, according to the proven reserves and consumption of energy in the world at present, these energy resources can only be consumed by the world for about 172 years. According to the current international energy forecast, oil resources will be exhausted within 40 years, natural gas resources will be exhausted within 60 years, and coal resources can only be used for 220 years.

It can be seen that in the long history of human development and utilization of energy, the period in which fossil energy such as oil, natural gas and coal dominated is only a short period, and they will eventually be exhausted and replaced by new energy. Humans must plan ahead and find new alternative energy sources as soon as possible. Research and practice show that new energy resources are abundant, widely distributed, renewable and pollution-free, and it is recognized as an ideal alternative energy source by the international community. According to the prediction of international authoritative units, by the 265438+60s, that is, by 2060, the proportion of global new energy sources in the world will reach more than 50%, and it will become the cornerstone of the future energy of human society, the protagonist of the world energy stage, and also an alternative energy source of fossil energy that is widely burned at present.

(2) The new energy is clean, with less pollutant emissions, and it is a clean energy that is in harmony with the earth's ecological environment on which human beings depend.

The large-scale development and utilization of fossil energy is one of the main reasons for air and other types of environmental pollution and ecological destruction. How to protect the earth's ecological environment on which human beings depend while developing and utilizing energy has become a major global issue. Global climate change is a major global environmental problem that the international community is generally concerned about at present. It is mainly caused by the emission of greenhouse gases, such as CO2, produced by burning a large number of fossil fuels in the industrialization process of developed countries. Therefore, limiting and reducing the emission of greenhouse gases such as CO2 from fossil fuel combustion has become an important part of the international community to slow down global climate change.

Since the industrial revolution, about 80% of the additional climate forcing caused by greenhouse gases is caused by human activities, of which CO2 accounts for about 60%. The combustion of fossil fuels is the main source of CO2 emission in energy activities. It is estimated that the CO2 emissions caused by energy activities in China are about 580 million tons of carbon, accounting for 9.76% of the global CO2 emissions of fossil fuels.

Observation data show that in the past 100 years, the global average temperature rose by 0.3-0.6 degrees Celsius, and the global sea level rose by 10-25 cm. If greenhouse gas emission reduction measures are not taken, the global average temperature will increase by 0.2 degrees Celsius every 10 year and by 1-3.5 degrees Celsius in 2 100 year in the next few decades. In recent years, due to the substantial increase of urban cars, automobile exhaust produced by burning gasoline has become an important pollution source of urban environment.

The pollutant emission of new energy is very small. At present, the carbon emission rate of various power generation modes is G carbon (/kwh): conventional coal-fired power generation is 304, coal gasification combined cycle power generation is 270, gas combined cycle power generation is 1 18, solar thermal power generation with natural gas-fired standby unit is 47, geothermal power generation is 2.5, and photovoltaic power generation and wind power generation are 0. It can be seen that new energy is clean energy to protect the living environment. It is an important measure to protect the ecological environment and take the road of sustainable economic and social development to adopt new energy to gradually reduce and replace the use of fossil energy.

(3) New energy is a practical energy source for solving the power supply problem and special use of more than 2 billion people without electricity in underdeveloped countries.

Up to now, there are still more than 2 billion people in underdeveloped countries in the world without electricity, including about 60 million people in China. Because there is no electricity, most of these people still live a poor and backward life, working at sunrise and resting at sunset, far away from modern civilization. These places lack regular performances ... >>

Question 4: Science: Talk about the necessity of developing new energy. 1. New energy and renewable energy are the cornerstones of the future energy of human society, and they are the alternative energy of fossil energy.

2. New energy and renewable energy are clean, and there is almost no pollutant discharge. It is a clean energy source in harmony with the earth's ecological environment on which human beings depend.

3. New energy and renewable energy are practical energy sources for solving the power supply problem and special purposes of more than 2 billion people without electricity in underdeveloped countries.

There is less and less non-renewable energy in the world, and it will not be used up eventually. In this process, the prices of the energy we are using will become more and more expensive. Therefore, only the development of new energy is an important guarantee for future development. People who have no long-term worries will have near worries. This is a fact.

Question 5: Why should we develop new energy sources first? New energy is a relative concept. For example, the main energy source at the beginning of last century was coal, while the new energy source at that time was oil. For example, nuclear energy is a new energy source for most countries, but it is a conventional energy source for France (the utilization rate of nuclear energy is high).

Second, with the continuous development of economy, energy consumption is increasing, traditional fossil energy is unsustainable, and economic development is increasingly restricted by energy development and utilization. As an alternative energy source, new energy can greatly alleviate our energy demand and ensure the sustainable development of the future economy.

Thirdly, the environmental problems brought by the utilization of traditional fossil energy are becoming more and more serious, endangering human health and living environment, especially the massive emission of co2, which leads to global climate change, while new energy provides us with an alternative way to solve environmental problems, and most of them are renewable and pollution-free.

Fourth: From the national level, in order to occupy the commanding heights of future energy utilization competition, we should develop new energy technologies and equipment now to prepare for future global competition.

Question 6: Why develop new energy sources? Reason 1: Conventional energy sources are mainly non-renewable energy sources, such as coal, oil and natural gas. These energy sources are used less and less, and will be exhausted one day. Therefore, we must plan ahead and develop new energy sources to replace these conventional energy sources.

The second reason: with the rapid development of the world economy, the demand for energy is increasing, and the existing energy supply will become more and more tense, which also requires us to develop new energy sources.

Reason 3: Most of the new energy sources are clean energy, and replacing some conventional energy sources can reduce environmental pollution.

Question 7: What is the significance of developing and utilizing new energy? Hehe, it means a lot. Now many energy sources are non-renewable. If we don't develop new energy, it will be more difficult in the future.

Question 8: Why should China vigorously develop new energy sources? The shortage of traditional energy in China is becoming more and more serious. Both coal and oil are non-renewable energy sources, so the energy crisis will gradually emerge. New energy will alleviate the energy crisis, which is of practical significance to energy conservation and emission reduction in China. Countries all over the world are competing for new energy sources, looking for sustainable energy strategies for themselves and speeding up the meeting of energy resources necessary for economic development. Moreover, climate change requires us to develop clean energy, and the pollution of traditional energy to the environment is beyond doubt. The problem of climate change has sounded the alarm and is a problem faced by people all over the world.
