Today, the three main sources of energy consumption in the world are coal, oil and natural gas. Various new energy sources only account for less than 20% of energy consumption. They are still in their infancy and development space. is huge.
The two fundamental problems facing humanity in the 21st century are energy problems and environmental problems. The development of new energies is the only way to solve these two problems.
So, what are the new energy majors? Which schools are the best? How is employment development taking place?
1. New energy majors
New energy majors are energy sources that are being developed and used or are being actively researched and are to be promoted using new technologies. and new materials. The trialIts use is often recyclable and causes little or no pollution to the environment.
Such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy and nuclear fusion energy and other application technologies in various industries.
Solar energy is mainly photothermal and photovoltaic, mainly photovoltaic. The basic principle of electricity production is the “photovoltaic effect”.
Biomass energy mainly uses biological conversion technology and thermochemical conversion technology to convert biomass into fuel materials.
For example: wheat straw, rice husk, sawdust, branches, bark and other agricultural and forestry wastes can become the main materials for energy production from biomass and be converted into various sources of prop energyre, such as biogas, fuel. ethanol, etc.
1. New energy science and engineering
New energy science and engineering mainly studies the types, characteristics, applications and future development trends of new energy, as well as related engineering technologies , including wind energy, solar energy, biomass energy, nuclear energy, etc.
New energy science and engineering belongs to the category of energy and energy, while new energy materials and devices belong to the category of materials.
2. New materials and energy devices
The connotation of the profession of new materials and energy devices lies in the integration of new materials and energy devices.
Take the example of electric vehicles. The development of power battery technologyevolves every day. For example, lithium titanate anode batteries have the advantages of fast charging performance, long life and high safety. The disadvantages are low energy density and high price, and are suitable for use in buses. Recently, carbon anode fast charging batteries have made rapid progress. They have high energy density and low cost and are expected to replace lithium titanate anode batteries.
3. New energy vehicle engineering
The specialization in new energy vehicle engineering takes mechanical engineering, electrical engineering and vehicle engineering as the main disciplines to train people who can engage in the design, manufacturing, and engineering in the field of new energy vehicle engineering. High-level, application-oriented talent with knowledgeprocess skills and capacity reserves for the development, production, testing and application of parts.
