Q:What are the contents of bio energy

Biomass includes plants, animals and their waste, garbage and organic waste water and other categories.

Q:Mainly for PetroChina, Sinopec, the state-owned monopoly enterprises to discuss

The term "energy", in the past, was rarely talked about. It was the two oil crisis that made it a hot topic. Energy is the basic driving force for the development of the whole world and economic growth. Since the industrial revolution, energy security issues began to appear. With the rapid development of the global economy today, the international energy security has risen to the height of the country, all countries have developed energy security as the core energy policy. Over the next more than and 20 years, with the support of stable energy supply, the world economy has grown considerably. However, in the enjoyment of human beings from energy economic development, technological progress and other interests, also encountered a series of inevitable challenges of energy security, energy shortage, resource competition and excessive use of energy and environmental pollution caused by problems such as the threat to human survival and development.

Class C mainly refers to household appliances, electrical appliances, electronic products in this regard

Q:I would like to ask you, China's electronic products have the use of energy classification, if so, what is the specific classification?

At present, more than and 100 countries have implemented energy efficiency labeling system. For the blue and white background color identification, divided into 1, 2, 3, 4, 5 a total of 5 grades,Level 1 indicates that the product has reached the international advanced level, the most energy saving, the lowest energy consumption;

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.

Q:Trademark registration of energy and environmental protection is the first category

Article 06: common metals and their alloys, metal building materials, transportable buildings of metal, metal rails, non electrical cables wires, five metal fittings, officer, safe, general metal products not included in other classes, oreClass 07: machines and machine tools, motors and engines (except for land vehicles), machine transmission couplings and transmission parts (except for land vehicles), non manual agricultural tools, incubatorsArticle 08: hand tools and implements (manual), cutlery, knives, razorArticle 09: Science, navigation, surveying, electrical, photography, film, optical, weighing, measuring, signal, inspection (supervision), ambulance (rescue) and teaching apparatus and instruments, apparatus recording, transmission or reproduction of sound and image, magnetic data carriers, recording discs, since the mechanical structure dynamic sales device and coin operated devices, cash register, computer and data processing device, fire extinguishing apparatus

Q:What are the new energy sources?

Generally there:Superconductive material, solar cell material, hydrogen storage material, solid oxide battery material intelligent material, magnetic material, nano material.Several new energy and new materials in the futureWave energy: ocean wave energy. This is an inexhaustible, renewable energy without pollution. It is speculated that the earth's Shanghai ocean wave energy stored up to 9 x 104TW. In recent years, the utilization of wave energy has occupied a place in the country's new energy development plan. Despite the high cost of wave energy generation, the need for further improvement, but the current progress has shown the potential commercial value of this new energy. A wave power plant in Japan has been running for 8 years, although the cost of generating electricity is higher than that of other power generation methods, it can save the cost of power transmission and so on. Currently, the United States, Britain, India and other countries have built dozens of wave power stations, and are running well.
