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: What is a one-time energy: Primary energy: refers to the natural form of the original form, the conversion of energy resources without processing. Natural energy.

Q: What is terminal energy consumption: The term energy consumption is mainly used in the energy industry, especially in the power industry. The following is a detailed description of the form of energy consumption: terminal energy consumptionThere are two forms of energy consumption, one is the direct consumption, also known as the terminal consumption; the other is the processing and conversion of consumption, also known as intermediate consumptionTerminal consumption is for intermediate consumption, refers to the energy is not used for intermediate processing conversion, but directly into a variety of heating, power and other equipment for production and non production activities of consumption, including:

Q: State approved products called new energy foods: What you say should be a new resource food?In China, the newly developed, newly discovered, the introduction of no eating habits, in line with the basic requirements of food, non-toxic harmless to the human body, said the new resources of food.

Q: Can the total energy consumption (equal value) be calculated in terms of the sum of the equal value of electricity and other energy: Energy consumption: unit energy consumption is the main index to reflect the level of energy consumption and energy saving, the ratio of primary energy supply to gross domestic product (GDP) is an indicator of energy efficiency. The index shows the degree of energy utilization in a country's economic activities, reflecting changes in economic structure and energy efficiency.

Q: Definition of low carbon energy: The implementation of low-carbon energy refers to the development of clean energy, including wind energy, solar energy, nuclear energy, geothermal energy and biomass energy to replace coal, oil and other fossil fuels to reduce carbon emissions

Q: Energy Star certified product range: Upstairs to answer the news, is the United States energy saving certification, a lot of IT, TV/AV products have to do energy star; but the United States has a California CEC certification, but also energy-saving certification, but different from the energy star

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?: As for mobile energy products, it is recommended that you can search for a mother's film innovative product competition, look, there are many interesting things.
