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:What are the contents of bio energy
Many types of biomass specific plants, the main and we often see the wood, crop (straw, rice straw, wheat straw, cotton stalk, bean stalk, rice husk, weed and algae etc.). Among the non plant species, there are mainly animal manure, animal carcasses, organic components in wastewater and organic components in waste.
Q:What is the energy consumption per unit product
Definition: refers to the amount of energy consumed per unit of production, mainly has the following three kinds: (1) the comprehensive energy consumption per unit of product yield, refers to the number of all kinds of energy can produce average actual consumption, comprehensive energy consumption and corresponding product yield ratio.
Q:What is the classification of energy?
, more new energy has begun to meet human needs
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 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:How to solve the energy problem
The increase of investment in science and technology energy, and actively develop new products for energy saving, develop clean and renewable energy, and on China's high energy consumption, waste of resources of industrial enterprises to accelerate the technological transformation and upgrading, and actively optimize the industrial structure, promote energy conservation, improve energy utilization rate.
Q:Which products need to be marked energy efficiency logo
That nearly two years of practice, energy efficiency labeling system can promote the improvement of energy efficiency and energy saving technology, promote energy product market to efficient market transformation, plays an important role in regulating the energy product market, energy saving, protect the environment. Based on the severe energy situation and significant implementation effect, the promotion of energy efficiency labeling system is imperative. September 18, 2006, electric washing machines and air conditioning units are also included in the energy efficiency labeling products directory, for the relevant enterprises, they face not only challenges, but also more opportunities.
Q:State approved products called new energy foods
The difference between new resource food and health food:1 health food refers to food with specific health functions, and approval must also be clear that what has a health care function, and the need for a health care function marked and defined on the product packaging, the new food resource has one or more functions are not on the product introduction mark in detail.2 new resources of food and health food for the application of the crowd is different, the former applies to any population, while the latter is suitable for specific populations.
Q:What are the economic operating standards for energy equipment and systems?
The core of building a resource conserving society is to correctly handle the relationship between man and nature, through the efficient use of resources, rational allocation and effective protection, economic and social and ecological sustainable development. The basic symbol of a resource conserving society is the harmony between man and nature. 1, the establishment of national policies and laws and regulations to conserve resources to strengthen the country in all areas of growth and comprehensive conservation management. In the organization of the preparation of the "11th Five-Year" national economic and social development master plan, special planning, regional planning and urban planning, we should save resources in the central position. The government should improve and perfect the resource conservation policies and regulations and supervision system, formulate corresponding policies and measures to encourage the economical use of resources, improve regulations and standards, the implementation of resource consumption and pollutant emission control strictly, and strengthen the binding force of saving resources work. To study and formulate "energy conservation law" and the "Cleaner Production Promotion Law) supporting regulations and regulations comprehensive utilization of resources, recycling of renewable resources, develop the industry of high consumption of resources to improve market access standards, the main energy efficiency standard, organization revised the main energy consuming industries for energy conservation design, develop key industry clean production evaluation index system.
