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 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: What is the classification of energy?: , more new energy has begun to meet human needs

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: What is the energy consumption per unit product: (2) the individual energy consumption per unit product output refers to the amount of a certain amount of energy consumed in the production of a particular product. The index reflects the quantitative relationship between inputs and outputs. (3) the energy consumption per unit of comparable products refers to the total energy consumption per unit product of the same product in accordance with the standard process or standard product output under the same production conditions. Index Interpretation: this indicator reflects the level of production technology, product quality and management level of various industries and enterprises. It is the main index to evaluate the economic benefit and energy saving plan of the enterprise, and it is the important basis to formulate and modify the energy consumption quota and the product cost accounting. The characteristics of this index is, in the same industry between the various business units energy consumption comparable to eliminate similar between enterprises, because the product structure, production process, supply and demand structure caused by the different energy consumption are not comparable to the effect.

Q: What is the cost effectiveness ratio of energy management in energy quality?: More and more countries pay attention to the energy efficiency of electrical products in the world, and now many countries regard the energy efficiency requirements as one of the mandatory targets for the sale of the products:EU: ErP (instead of EuP), European flower, CoC...United States: Energy Star (Energy Star), CEC, DoE...Canada: NRCan,Australia: MEPS,Korea: MEPS,China: CECP,

Q: And the world's oil futures and other energy futures prices related to China's domestic futures varieties which futures? Seek expert futures and futures experts cited. Thank you: Third: for example, methanol, linear low density polyethylene, polyvinyl chloride, sugar, purified terephthalic acid, etc.. Note: white sugar is a substitute for oil, so it is related to the rise and fall of oil

Q: What is the difference between primary and secondary energy sources two: An energy is taken directly from nature without a variety of energy and resources, processing including coal, crude oil, natural gas, oil shale, nuclear, solar, hydro, wind, wave energy, tidal energy, geothermal energy, biomass energy and ocean thermal energy and so on.
