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.
