Q: What is a one-time energy: Primary energy refers to the exploitation of natural resources, the direct use of energy, natural resources (such as coal, crude oil, sunlight, uranium, etc.) contained in the human without conversion or conversion of energy.

Q: New energy technology applications, including the professional: 4 related to power generation, (our country has only one qualification qualification, registered electrical engineer. Among them, there are two directions, power transmission and distribution, power distribution XX class is very sorry, although wind power, photovoltaic power generation is the country but only recognized the development of power transmission and distribution and other professional;

Q: What are the sources of energy that are common in life and the two energy sources: The energy product obtained after the primary energy is processed and converted is called the two energy source, such as electricity, diesel oil, gasoline, etc.

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: 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: I would like to ask you, China's electronic products have the use of energy classification, if so, what is the specific classification?: Level 4 indicates that the energy efficiency of the product is lower than the market average;Level 5 is the market access indicators, below the grade requirements of the product does not allow production and sales.

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: Article 02: paint, varnish, paint, rust and wood preservatives, colorants, mordant, raw natural resins, painters, decorators, printers and artists with metal foil and powderArticle 03: laundry bleach and other materials, cleaning, polishing, scouring and abrasive preparations, soap, spices, essential oils, cosmetics, shampoo, toothpaste

Q: What is the comprehensive calculation of energy production?: Energy production is not equal to the sum of all kinds of energy into standard coal, because the two energy is generated by the primary energy conversion, so the total energy production can only be a variety of primary energy production and the standard coal

Q: What are the new energy sources?: New energy and new materials is a new concept of science and technology, which is based on the concept of environmental protection.New energy and new material features: superior performance of some materials, with better performance than traditional materials.
