Q: How to solve the energy problem: Market economy is open, China should vigorously develop the international energy market, make full use of the international and domestic two kinds of resources, and expand the way and quantity of energy imports

Q: What are the types of new energy vehicles: 3, hydrogen power vehicle:A car that uses hydrogen as fuel. Hydrogen powered vehicles is a truly zero emission vehicles, emissions from pure water, zero emissions, has no pollution, abundant reserves and other advantages, therefore, hydrogen powered vehicles is the ideal alternative to traditional car. However, the hydrogen fuel cell costs are too high, and hydrogen storage and transportation of fuel in accordance with the current technical conditions are relatively difficult.

Q: What are the sources of energy that are common in life and the two energy sources: The two energy is converted into the form of energy. For example, if coal is used directly to burn, we are using the primary energy. If coal is used to generate electricity, the electricity generated is the two energy.

Q: What is terminal energy consumption: 1 as fuel, power use of energy refers to the energy into a variety of heating, power and other equipment, the production of light, heat, power consumption of energy2 as the raw materials used in industrial production. Energy refers to energy activities, as raw material is put into use, after a series of chemical reactions, gradually transformed into a new non energy products, such as chemical fertilizer plant for the production of synthetic ammonia, chemical factory production of synthetic rubber products such as the consumption of natural gas and coal coke consumption; production of dyes, plastics, textile products of raw oil.

Q: Which products need to be marked energy efficiency logo: As the first step in the construction of China's energy efficiency labeling system, household refrigerators and room air conditioner energy efficiency labeling system was officially implemented in March 1, 2005. According to the first batch of energy efficiency labeling product catalogue and related requirements, since March 1, 2005, every household air-conditioning and refrigerator production, sale, import Chinese must be labeled "Chinese energy label" label, no logo products will be allowed to market sales.

Q: What are the contents of bio energy: Bio fuels (2) biodiesel (3) biogas (1) biogas (4) bio butanol (5) microalgae oil (6) biomass power generation

Q: Energy Star certified product range: The premise is to have UL FCC to do energy starIn short, life and efficiency test

Q: What is the difference between energy star and DLC: In the field of electronic energy consuming products, especially for the energy efficiency of lighting products, Anbotek as a EPA accredited laboratory in the United States, has more than and 10 years of experience, while obtaining the following authorization:EPA recognized Energy Star Testing LaboratoryCalifornia energy efficiency accreditation LaboratoryAccess to the U.S. Department of energy's LIGHTING FACTS LABEL authorized testing laboratory

Q: And the world's oil futures and other energy futures prices related to China's domestic futures varieties which futures? Seek expert futures and futures experts cited. Thank you: Third: for example, methanol, linear low density polyethylene, polyvinyl chloride, sugar, purified terephthalic acid, etc.. Note: white sugar is a substitute for oil, so it is related to the rise and fall of oil

Q: What is the difference between primary and secondary energy sources two: Primary energy can be further divided into two categories of renewable energy and non renewable energy. Renewable energy including solar energy, wind power, wind energy, biomass energy, wave energy, tidal energy, ocean thermal energy, etc.. They can be recycled in nature. Renewable energy, including: coal, crude oil, natural gas, oil shale, nuclear energy, etc., they can not be recycled, with a little, then a little less.
