Q: How to solve the energy problem: Actively play the basic role of the market in resource allocation, increase the energy development investment, increase energy supply, and play the role of national macro-control, coordination of energy development in China, to increase the energy development policy support, to ensure the stable and rapid development of China's energy production.

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: State approved products called new energy foods: New resource food management approach provides that the new resource food has the following characteristics:Animals, plants and microorganisms in China without eating habits;(two) new varieties of microorganisms used in food processing;(three) because of the use of new technology to produce food ingredients that result in changes in the original composition or structure.

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: What are the tax policies for renewable energy companies?: The national development and Reform Commission had issued the "renewable energy and long-term development plan" put forward, to 2020 the proportion of renewable energy in the energy structure to reach 16%, the proportion is still less than 1%. plan to increase financial input, the implementation of preferential tax policies "set down as a principle of the development and utilization of renewable energy.

Q: China's new energy situation? The biggest obstacle? What can be learned abroad?What is the most important countermeasure in our country?: Take real estate as an exampleReal estate dataPart I: Research SectionSection 1: Market Research

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: 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.

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 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: At present, what are the main types of new energy vehicles?: Fuel cell electric vehicle (FCEV):The utility model relates to a motor which is driven by a chemical reaction, and is driven by a motor.
