Abstract: Energy consumption occurs in our lives all the time. my country is the third largest country in energy consumption in the world. With the rapid development of productivity, energy consumption is also increasing. Among them, oil and coal consumption account for a large proportion. However, with the gradual warming of the global climate and the depletion of oil resources in recent years, the development of new energy sources is extremely urgent. This paper mainly takes biomass energy as an example, and analyzes the current development status and existing technologies to carry out new energy sources. The future of technology.
1 Development status of new energy technologies
Energy has always played an irreplaceable role in our lives. The development of human society is inseparable from the emergence of high-quality energy and the use of advanced energy. Since ancient times, my country's energy consumption has been dominated by primary energy such as oil and coal. Years later, with the outbreak of the oil crisis, people began to realize the problem of the energy crisis. Oil and coal are not inexhaustible. in an energy crisis. At the same time, the global climate problem has become increasingly serious in recent years, and the greenhouse effect caused by excessive carbon dioxide emissions has begun to attract people's attention. Therefore, based on two points, the country vigorously develops clean, non-polluting and renewable energy technologies and regards them as energy development. An important part of the strategy to solve the problems of traditional energy consumption.
It is often said that "the 21st century is the century of biotechnology, the century of information technology, and the century of the ocean." At present, my country's new energy technologies are mainly reflected in nuclear fusion technology, biomass energy technology, the development of marine energy, the development of solar energy, In the future, the development of lunar energy, etc., will use a more advanced and pollution-free way to utilize energy.
2 Biomass energy technology
Biomass energy mainly refers to solar energy in the form of chemical energy, which is absorbed into the body by the chlorophyll of green plants through photosynthesis and stored. It can be converted into solid, liquid and gas fuels through technology. It belongs to renewable energy, mainly including straw. , sugarcane, municipal waste, forestry waste and other waste gas materials. The utilization of biomass energy technology solves the problem of carbon energy depletion to a certain extent, and at the same time, its advantages of non-polluting emissions also alleviate the phenomenon of global warming to a certain extent. Since biomass energy is mainly the utilization of crops and other materials, it has played a certain role in promoting the development of rural areas in my country. In 1998, the total domestic energy consumption in rural areas was 365 million tons of standard coal, of which straw and firewood were 207 million tons of standard coal, accounting for 56.7%. From this, it can be seen that the development of biomass energy technology plays an important role in the development of these regions, and it is the driving force for vigorously developing the economy in poor rural areas and moving towards a well-off society.
Biomass energy has the advantages of renewable, clean and low-carbon, substitution advantages, and abundant raw materials. It is the fourth largest energy source after coal, oil and natural gas, and is the most extensive renewable resource. Every year, the total amount of waste crops produced in my country is Biomass is abundant, and if it is not used rationally, it will easily lead to waste of resources and low utilization rate. Therefore, the development of biomass technology is particularly important. Countries are constantly developing in terms of biomass technology. The United States has formulated a series of policies to carry out The utilization process of biomass technology provides support and guarantee. For the traditional fossil fuel substitute fuel ethanol, which has attracted much attention today, the production volume of the United States ranks first in the world; the EU mainly produces biodiesel through biomass technology. , to replace traditional diesel oil, and use energy in a greener way; the bioenergy utilization technologies currently being developed in my country mainly include thermochemical conversion technology, biochemical conversion technology, and biomass briquetting technology. It mainly produces combustible gas, tar, charcoal, biogas, alcohol, high-density solid fuel, etc., and further supports the development of biomass technology by formulating relevant policies, so as to broaden the field and vigorously develop new energy technology.
3 Future Prospects of New Energy Technology
As a new way of energy utilization, new energy technology is unrealistic to completely replace traditional energy utilization. First of all, it is reflected in people's lack of attention and understanding of this energy. Taking biomass energy as an example, as a traditional A major agricultural town, Tanfang Town, Qingzhou City, Shandong Province has an area of 150,000 mu of arable land. Only agricultural production produces about 600,000 tons of plant straw every year. According to the survey, 50% of farmers choose to burn the straw directly in order to save trouble. , is relatively unfamiliar with the concept of "turning waste into treasure", and is not aware of the efficient utilization of energy from straw, so this is the first problem to be solved at present.
Secondly, it is reflected in the brain drain and technical limitations. Most of the new energy product manufacturers in my country are too scattered and not centralized, and the technological equipment is limited in terms of advanced nature, so the development of biomass technology is limited to a certain extent, and there is also a lack of technical education and lack of relevant fields. Advanced education, or relevant personnel choose to work in foreign companies, resulting in the phenomenon of brain drain.
In response to the above problems, we can improve and solve them from the following aspects: increase policy efforts. Vigorously publicize the advantages of new energy technology development, provide policy support, so that people can understand the trend of new energy utilization, and provide policy guarantees for new energy utilization.
The cultivation of independent innovation ability. At present, on the issue of developing new energy technologies in my country, key and core technologies are highly dependent on foreign countries, and independent innovation is insufficient. The most fundamental limitation of my country's new energy utilization is this. The introduction of foreign advanced technology is a phenomenon that exists at present. The phenomenon that this core technology is controlled by people due to its own lack of innovation is largely restricted. With the development of my country's new energy technology utilization, it is particularly important to improve the ability of independent innovation.
New energy technology utilizes resources in a more advanced and pollution-free way, which will undoubtedly have a huge impetus for the sustainable development of society in the future.
