Current situation and prospect of new energy

Generation and development of new energy

With the acceleration of industrialization and urbanization in China, people's demand for energy is increasing. However, the traditional way of energy utilization has brought a series of environmental problems. With the enhancement of people's awareness of environmental protection and the progress of science and technology, new energy has gradually become the main development direction to replace traditional energy. This paper briefly introduces the origin, development and future development trend of new energy.

origin:

The concept of new energy originated in the early 20th century, when people realized that the traditional energy brought environmental pollution, harm to human health, people began to explore new energy. Solar energy is one of the earliest new energy sources in the world, Einstein published a paper on the photoelectric effect in 1905, which laid a solid foundation for the research of solar energy. Since then, people's research and application of solar energy has gradually increased, and by the 1960s, solar panels have been widely used.

Nuclear energy is another important new energy in addition to solar energy. It was not until the 1930s that human beings began to study nuclear fission, and in 1945, after the successful development of the first atomic bomb in the United States, nuclear energy really became a new type of energy and was widely used.

New energy is a new type of energy, and its development has experienced the process from minority to popularization. In recent decades, new energy such as solar energy, wind energy, biomass, geothermal energy, tidal energy and so on have attracted wide attention.

Solar energy is currently the most mature of a new energy, although the efficiency of photovoltaic power generation is relatively low, but with the progress of technology, the efficiency of photovoltaic power generation is getting higher and higher, the cost is getting lower and lower, more and more families, companies began to install solar photovoltaic panels, and the surplus power to the network, which makes photovoltaic power generation gradually popular.

Wind energy is widely used as a new energy source, especially in Denmark and Germany, two countries with long coastlines, where wind energy accounts for a larger proportion. Wind turbine works in the way of wind energy. Because of its relatively simple engineering implementation, it has high application value and low cost.

Biomass energy is a relatively new energy source, which uses biomass energy as raw material and is converted into energy by burning or other means. In addition to preparing biomass fuel, biomass energy can also be used to prepare biomass ethanol, biological gas, etc., which has broad application prospects.

Future trend:

With the increasing energy consumption in the world, the research of new energy technology has been paid more and more attention. In the past decade, China's new energy technology has made great progress, and breakthrough progress has been made in some key technologies. This paper focuses on the current situation and prospects of China's new energy technology development, including the breakthrough of new energy key technologies, the development of new energy industry chain, and the opportunities and challenges faced by new energy.

Key technological breakthrough:

With the development of science and technology, people's requirements for new energy technology are also increasing. In this context, a series of innovations and breakthroughs have emerged in the field of new energy. Among them, solar energy technology, wind energy technology, biomass energy technology, etc., are more mature technologies, while ocean energy technology, water energy technology, hydrogen energy technology, etc., are rapidly developing technical fields.

Solar power generation is the most mature new energy in the world today. With the development of solar technology, the photoelectric conversion efficiency of solar cells has been continuously improved, which has brought new development opportunities to the photovoltaic industry. In the construction process of photovoltaic power station, the use of new solar panels and modules can improve the output power of solar panels, improve efficiency, and extend the service life, which is the key to the breakthrough of solar technology.

At the same time, there have been major breakthroughs in wind power technology. With the continuous optimization of wind turbine structure, wind power efficiency continues to improve, and gradually develop to the direction of scale and technology. The development of wind power generation technology can not only reduce the environmental load, but also provide new impetus for the country's energy construction and development.

In addition, biomass energy technology has also been widely concerned. Biomass energy technology takes organic matter such as plants, trees and municipal waste as the main raw materials, and uses bioreactor, microbial fermentation, chemical reaction and other technologies to convert biomass energy into fuel, heat and other energy sources, which greatly improves the utilization rate of biomass energy resources.

We will develop the new energy industrial chain:

With the wide application of new energy technologies, the status of the new energy industry in the national economy will continue to improve. New energy industry chain refers to the new energy as the core, the construction of storage, transmission, energy conservation and other industrial chains, to achieve the development of the whole industry chain of new energy.

Take the solar industry as an example, the production of solar cells and modules is its most basic part. Today, China's solar cell and module manufacturing industry has gone abroad and become a global leader in solar cell manufacturing. In addition, in the construction of photovoltaic power stations, solar panels, inverters, DC cabinets, AC cabinets and other supporting equipment have been gradually scaled up, so that the solar energy industry chain has been comprehensively developed and improved.

The wind power industry chain is also evolving. In the whole wind power industry chain, the manufacturing and service of wind power equipment is the most core part. With the continuous progress of wind power technology, the wind power industry has become an important force in the development of new energy in China. In addition, wind power transmission and transformation lines, energy storage devices are also gradually established and improved.

The new energy industry chain not only plays a driving role in the new energy industry, but also plays a promoting role in other industrial chains. For example, the emergence of new energy electric vehicles not only promotes the construction of the new energy industry chain, but also has an important impact on the fields of automobile manufacturing, power transmission and energy storage.

Prospect and challenge；

New energy technology is a promising area, but also a challenging one. First of all, the cost of new energy technology is high, to give full play to its economic benefits, environmental benefits and other advantages, but also need to carry out technological innovation.

Second, at the current stage, new energy technologies are still facing stable and reliable challenges. Due to the influence of external environmental factors, the collection and conversion technology of solar energy, wind energy and other new energy still has some problems such as stability and reliability.

Finally, the support of new energy technology in policies, regulations and markets is also one of the key factors in the development of the new energy industry chain. Therefore, in terms of policies and market mechanisms, regulations and policies need to be further improved to create a better investment environment, market environment and business environment for the development of new energy technologies.

In short, new energy technologies play a pivotal role in economic development and environmental protection. The rapid development of the new energy industry requires breakthroughs in key technologies and industrial chains. Although new energy technologies still face many challenges, we believe that new energy technologies will be widely used in the near future.

outline:

New energy is the main direction of replacing traditional energy, although its development history is short, but the application prospect is broad, is an important direction of future energy development. In the process of practical application, we must also strengthen technological innovation and progress, open up new areas, improve the efficiency of new energy use, and jointly build a sustainable future.
