Q: Metro energy feedback products which good?: Before the subway brake is to use the electricity directly with the resistance to let go, so that it will cause a waste of electricity, as well as investment in two refrigeration equipment, this is very environmentally friendly. Shenzhen Sheng Hong electric for this problem has developed a product called UESS, to solve this problem, but also to solve the UESS Metro Traction voltage problem.

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: 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 new energy products: Traditionally, including thermal power, hydro power, nuclear power generation, as a result of the new energy is more extensive, in addition to the above said, such as wave power generation, biogas power generation, tidal power generation, etc., are new energy

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.
