Q:Types of energy market in China
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:Coal washing products are primary energy, or the two energy?
It can be useful to calculate and analyze the efficiency of energy use, which can be divided into primary energy and two energy sources. The general criterion for division is that any source of energy that is directly from the natural world, which is not processed or converted, is called "primary energy".
Q:What is the general energy?What do we usually say about energy conservation?
Fourth energy conservation is a long-term strategic policy of the country's economic developmentThe State Council and of the provinces, autonomous regions, municipalities directly under the Central People's Government shall strengthen energy conservation, rational adjustment of industrial structure, enterprise structure, product structure and energy consumption structure, promote technological progress in energy conservation, reduce energy consumption per unit of output value and energy consumption per unit of product development, processing, conversion, transmission and supply of energy gradually improve, improve energy efficiency, promote the development of the national economy to energy saving.The State encourages the development and utilization of new and renewable sources of energyFifth countries to develop energy conservation policies, the preparation of energy-saving programs, and into the national economic and social development plan to protect the rational use of energy, and economic development and environmental protection coordination
Q:New energy (photovoltaic products) now foreign trade market?
Survival of enterprises will have a new world. But trade may be harder to do,
Q:Trademark registration of energy and environmental protection is the first category
There are 45 categories of trademark classification in China. Firstly, it is necessary to choose the categories corresponding to the enterprises, and the trade mark should belong to the 11 category:Article 01: used in industry, science and photography, agriculture, horticulture and forestry chemicals, unprocessed artificial resins, unprocessed plastics material, fertilizer, fire extinguishing compositions, tempering and soldering preparations, preservation of food chemicals, tanning, industrial adhesives
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 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: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: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 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.
