Q: What is a one-time energy: Primary energy, also known as natural energy, refers to the use of natural resources that have not been changed or changed. Such as coal, crude oil, natural gas, water, wind energy, solar energy, ocean energy, tidal energy, geothermal energy, natural uranium, etc.. Primary energy is divided into renewable energy and non renewable energy, the former refers to the repeated generation of natural energy, the latter with a little less, mainly all kinds of fossil fuels, nuclear fuel.

Q: What is terminal energy consumption: 1 as fuel, power use of energy refers to the energy into a variety of heating, power and other equipment, the production of light, heat, power consumption of energy2 as the raw materials used in industrial production. Energy refers to energy activities, as raw material is put into use, after a series of chemical reactions, gradually transformed into a new non energy products, such as chemical fertilizer plant for the production of synthetic ammonia, chemical factory production of synthetic rubber products such as the consumption of natural gas and coal coke consumption; production of dyes, plastics, textile products of raw oil.

Q: What is a high value-added products: For example, river sand, chemical composition is silica

Q: What are the new energy products: Solar products: solar street lights, solar water heaters, etc.Nuclear energy: nuclear powerOcean Energy: wave power, tidal powerWind power: wind powerBiomass: made of liquid or gaseous fuels

Q: Which products need to be marked energy efficiency logo: China is the world's largest producer and consumer of household electrical appliances. The rapid growth of household appliances has brought huge energy consumption, but also increased the pollution of the environment. Countries around the world through the development and implementation of energy efficiency standards, the promotion of energy efficiency labeling system to improve energy efficiency of energy efficient products, and promote energy-saving technological progress, thereby reducing emissions of harmful substances and environmental protection.

Q: Total energy consumption and total energy production: Any of the two secondary energy products produced by the conversion of various energy sources (including other non - energy products and associated products)

Q: Energy Star certified product range: To do this, you can look for women, there is a laboratory to ensure that through, Baidu search: Ningbo Lan Xiaohua, we know, maybe a lot of places can help you in the future ~ ~ ~ ~ oh

Q: Trademark registration of energy and environmental protection is the first category: There are 45 categories of trademark classification in China. Firstly, it is necessary to choose the categories corresponding to the enterprises, and the trade mark should belong to the 11 category:Article 01: used in industry, science and photography, agriculture, horticulture and forestry chemicals, unprocessed artificial resins, unprocessed plastics material, fertilizer, fire extinguishing compositions, tempering and soldering preparations, preservation of food chemicals, tanning, industrial adhesives

Q: Mainly for PetroChina, Sinopec, the state-owned monopoly enterprises to discuss: So, what is "energy"? About the definition of energy, there are about 20 kinds. For example: the "Encyclopedia" of science and technology, said: "energy is from the heat, light and power and energy resources"; the "Encyclopedia Britannica" said: "energy is a include all fuel, water, sunlight and wind terms, humans can use appropriate means to make it provide the required conversion the energy for themselves"; "Japan encyclopedia" said: "in various production activities, we use energy, mechanical energy, energy and energy to work, can be used as the carrier of these various sources of power in nature, called energy"; China's "energy encyclopedia" said: "energy can be converted directly or by providing light, heat and power in any forms can be contained in energy resources needed for the human." It can be seen that energy is a source of energy in various forms.To be exact and simple, energy is a kind of material resources that can provide some form of energy for human beings.It is often referred to as sources of energy that can be used by humans to obtain useful energy.

Q: What is the difference between energy star and DLC: In the field of electronic energy consuming products, especially for the energy efficiency of lighting products, Anbotek as a EPA accredited laboratory in the United States, has more than and 10 years of experience, while obtaining the following authorization:EPA recognized Energy Star Testing LaboratoryCalifornia energy efficiency accreditation LaboratoryAccess to the U.S. Department of energy's LIGHTING FACTS LABEL authorized testing laboratory
