The power industry is the basic industry of the national economy, providing reliable energy security for social development. The power industry involves various links such as power generation, power transmission, power distribution and electricity consumption, which is an important part of modern society. The status of the power industry in the national economy Energy supply The power industry is one of the important pillar industries of the national economy, providing stable energy supply for various industries and promoting socio-economic development.

The water treatment industry refers to the whole industrial chain system covering the development, utilization, protection, intelligent management and related services of water resources, the research and development and manufacturing of technical equipment, including raw water, water supply, water conservation, drainage, sewage treatment and water resources recycling, which has basic and strategic industrial attributes. The core goal of this industry is to promote the safe and efficient use of water resources and the healthy and sustainable development of the water ecosystem.

The chemical industry includes chemical, oil refining, metallurgy, energy, light industry, petrochemical, environment, pharmaceutical, environmental protection and military departments engaged in engineering design, fine and daily chemical industry, energy and power, technology development, production technology management and scientific research.

The oil industry is the industrial sector that extracts oil (including natural oil, oil shale, natural gas) and refines and processes it. It is composed of oilfield geological exploration, oilfield development and oil exploitation, transportation, refining and processing and other units. Petroleum is the "blood" of industry and an important industrial energy source.

The metallurgical industry refers to the industry of refining, processing and manufacturing metal ores, metal scraps, etc. by using physical, chemical and mechanical principles and technologies related to metals. The metallurgical industry covers a wide range of fields, including metallurgical raw material mining, metallurgical process technology, metallurgical equipment manufacturing, etc. According to the different links and characteristics of the metallurgical industry chain, the metallurgical industry can be classified.

Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud and volcanic gas, coalbed methane and biogenerated gas, etc.). The use of natural gas as energy can reduce the amount of coal and oil, thus greatly improving the problem of environmental pollution;

The pharmaceutical industry is an important part of China's national economy and an industry that combines traditional and modern industries. Its main categories include: chemical raw materials and preparations, traditional Chinese medicinal materials, traditional Chinese medicine slices, proprietary Chinese medicine, antibiotics, biological products, biochemical drugs, radioactive drugs, medical devices, sanitary materials, pharmaceutical machinery, medicinal packaging materials and pharmaceutical commerce. The pharmaceutical industry plays a very important role in protecting and improving people's health, improving the quality of life, family planning, disaster relief and epidemic prevention, munition preparation, and promoting economic development and social progress.

New energy is relative to traditional energy sources such as coal, oil and natural gas. It is also known as unconventional energy, which refers to various forms of energy other than traditional energy. It refers to the energy that has just begun to be developed and utilized or is being actively researched and promoted [7]. Including solar energy, geothermal energy, wind energy, ocean energy, biomass energy and nuclear fusion energy, etc., with green and low-carbon, no risk of resource depletion, falling energy prices and other characteristics, it is the key area of energy development in the future.
