Q: What is the C type of the product type in the notebook computer?: Product characteristics and brand image as important; B products such as food, medicine, etc., D products such as snacks, beer, beverages, etc..

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: What are the contents of bio energy: Bio energy is a kind of renewable energy, which can convert biomass, water and other inorganic substances into biogas, hydrogen and other flammable gases or ethanol, oil and combustible liquid.

Q: China's new energy situation? The biggest obstacle? What can be learned abroad?What is the most important countermeasure in our country?: (1) the basic purchase characteristics of target consumers(2) target consumers' evaluation of target areas and projects(3) analysis of the characteristics of target consumers' purchase of competing products(4) consumers' cognition and cognitive approach to target market

Q: Can the total energy consumption (equal value) be calculated in terms of the sum of the equal value of electricity and other energy: Equivalent value is a measure of the energy of the unit itself

Q: Definition of low carbon energy: Low carbon energy is an alternative to high carbon energy sources, it refers to carbon dioxide and other greenhouse gas emissions low or zero emissions of energy products, including nuclear energy and a part of renewable energy.

Q: What are the new energy sources?: Combustible ice: This is a solid compound of methane and water, which is similar in appearance to ice". Combustible ice is stable at low temperature and high pressure, and the combustible gas released by ice melting is 100 times that of the original solid. It is estimated that the amount of combustible ice is more than the total amount of coal, oil and natural gas on earth.Coalbed methane: during the formation of coal due to the increase in temperature and pressure, while the deterioration of the release of combustible gas. From peat to lignite, per ton of coal produced 68m3 gas; from peat to coal per ton of coal produced 130m3 gas; from peat to anthracite coal per ton of coal produced gas 400m3. Scientists estimate that the earth's coal-bed methane up to 2000Tm3.

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 cost effectiveness ratio of energy management in energy quality?: The laws of the state set the maximum value for the former, which set the minimum value; as a rigid index of energy efficiency regulationsAlthough different countries have different national conditions according to different national conditions, these two points are regarded as the final judging index

Q: What is mobile energy? A new kind of energy? There is no actual product?: Mobile energy is not a specific thing, is a new way of energy use. This is a new concept of Hienergy raised last year, which is not subject to local constraints can provide energy, and can move, no matter where, as long as the sun, it can provide power.
