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: 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 is the classification of energy?: Energy can also be divided into different types. There are seven main points: the source is divided into the following 3 categories: the energy of the earth itself usually refers to the earth...

Q: Total energy consumption and total energy production: The output of the refinery, gasoline, kerosene, diesel oil, fuel oil, liquefied petroleum gas, refinery gas and other petroleum products (naphtha, solvent oil, raw oil, paraffin wax, lubricating oil, asphalt, etc.) gas output is the coke gas and other gas, coke and other coking products (coal tar crude, etc.).

Q: Definition of low carbon energy: The implementation of low-carbon energy refers to the development of clean energy, including wind energy, solar energy, nuclear energy, geothermal energy and biomass energy to replace coal, oil and other fossil fuels to reduce carbon emissions

Q: Trademark registration of energy and environmental protection is the first category: Article 06: common metals and their alloys, metal building materials, transportable buildings of metal, metal rails, non electrical cables wires, five metal fittings, officer, safe, general metal products not included in other classes, oreClass 07: machines and machine tools, motors and engines (except for land vehicles), machine transmission couplings and transmission parts (except for land vehicles), non manual agricultural tools, incubatorsArticle 08: hand tools and implements (manual), cutlery, knives, razorArticle 09: Science, navigation, surveying, electrical, photography, film, optical, weighing, measuring, signal, inspection (supervision), ambulance (rescue) and teaching apparatus and instruments, apparatus recording, transmission or reproduction of sound and image, magnetic data carriers, recording discs, since the mechanical structure dynamic sales device and coin operated devices, cash register, computer and data processing device, fire extinguishing apparatus

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 comprehensive calculation of energy production?: Energy production [statistics] the statistics reflect energy production scale, energy production structure, main indicators of production results and development speed, for the preparation of energy production plan, check the energy production schedule, reasonable composition analysis by energy, provide an important basis for the rational development of energy. According to the origin of energy, it can be divided into primary energy output and two energy output.

Q: Coal washing products are primary energy, or the two energy?: Based on this, I think it is wrong to put the coal washing products (washed coal, washed coal, washed coal, etc.) as the two energy. This is because the coal washing and processing is different from the general primary energy products to secondary energy products. Coal is mainly through jigging and flotation process will be different, the proportion of the physical size of the coal area separated from the mixed gangue in the coal removed

Q: What is the difference between primary and secondary energy sources two: The primary energy obtained by processing the converted energy products, known as the two energy, such as electricity, steam, gas, gasoline, diesel oil, heavy oil, liquefied petroleum gas, ethanol, methane, hydrogen and coke etc..
