    New Review: China to develop clean energy

    China’s largest production base of solar power facilities - Yingli New Energy Resources Co., Ltd. Industrial Park Phase III photovoltaic Baoding in recent high-tech zones in the foundation, in an increasingly tight energy crisis background dell latitude d820 battery,dell latitude d830 battery,dell latitude x300 battery, this project shows that the production of unusual message: China will vigorously develop clean energy.

    Since 2003 the construction of Yingli national high-tech industrialization demonstration project - polycrystalline silicon solar cells and applications projects, the company will embark on a rapid development. In 2004, the company put into operation all three production lines, annual output of six megawatts of silicon, the battery 10 MW, 50 MW components. These products have passed a series of international certification, successfully entered the international market. With the second phase of production expansion project, so that China’s domestic polysilicon ingot, slicing and battery again to upgrade the overall capacity, production technology to achieve new breakthroughs in China also marks the level of R & D and manufacturing of photovoltaic industry has now entered advanced in the world. In 2005 the company achieved sales revenues of 530 million yuan, profit billion, exports more than 50 million U.S. dollars.

    Experts believe that China’s large population and low per capita energy resources, development of renewable energy is an inevitable choice for China, including solar power generation is the most promising technologies.

    Experts predict that within the next twenty to thirty years, the global energy mix will be a fundamental change in the fifties of this century, new energy and renewable energy will account for the entire energy constitutes 50%. Solar energy as a great potential for development of new and renewable sources of energy, has long drawn the world attention.

    Under the authority of the world’s energy analysis, the world has proven a major fossil fuel reserves and production can not be optimistic about the world. Length of remaining recoverable oil only, length of remaining recoverable natural gas dell xps m140 battery,dell xps m1210 battery, dell 6y270 battery, remaining recoverable coal age, length of remaining recoverable uranium.

    Traditional fuel energy is being reduced day by day, energy issues can not be ignored have become global issues. Search for new energy sources, has become a top priority. And abundant solar radiation is inexhaustible and pollution-free, low-cost, free use of human energy and become the best choice for people. It is learned that the solar energy per second to reach the ground up to 800,000 kilowatts of energy, if the earth’s surface of 0.1% of solar energy to electrical energy, the change rate of 5%, equivalent to annual power generation of the world’s energy consumption about four times. China is rich in solar energy resources in the world. China has a desert area of 1,080,000 square kilometers, mainly distributed in the light of the northwest region is rich in resources. Area of one square kilometers can be installed 100 megawatts of photovoltaic arrays, generating 150 million a year degrees; 1% if the development and utilization of the desert, the Chinese will be issued in 2003 is equivalent to the annual power consumption.

    Tianwei Yingli in the second phase project put into operation immediately on the construction of three projects, the construction of the expansion of focus from a single shift production capacity and R & D both through the three projects Yingli became the world’s leading international photovoltaic industry of optical V Group. Yingli to build the third phase, China’s photovoltaic industry is the biggest investment ever, the largest capacity, most complete industry chain projects. The project total investment of three billion yuan, completed and put into production in 2008 will build 500 megawatts at the same time production base dell 75uyf battery,dell c1295, photovoltaic system research and development centers, training centers and other professionals, the actual annual production value of up to 16 billion yuan .

    Experts believe that the completion of the project will allow Yingli PV industry in one fell swoop into the international level, square, and domestic and foreign-led the development of related industries to enhance the overall development of China’s photovoltaic industry level; and on renewable energy in China applications, to promote and improve the environment and sustainable development, play an active role in promoting.

    How are we going to boost for the future “sunshine industries”

    Shih Rong-an in the “Bird’s Nest” main channel on the 12 solar photovoltaic power generation system for the entire industry a new opportunity for development. Although compared with the “Bird’s Nest,” a huge consumption of electricity, with a total installed capacity of 130 kilowatts of solar system small, but the industry are more willing to interpret such a move: China’s solar energy photovoltaic power generation, represented by the “sunshine industry” will usher dell gd761 battery,dell kd476 in a vibrant era.

    Tak hit the industry very attractive miracle.

    5 years ago, Shi Zhengrong, with 10 solar photovoltaic technology patents and 250,000 U.S. dollars from Australia home business, today, his Suntech Power Co., Ltd. has become the forefront of the world’s solar photovoltaic industry, with total assets of 1.8 billion yuan, the profit reached 400 million yuan. Even more surprising is that a short period of six months, Shi Zhengrong Suntech promote not only the New York Stock Exchange, and succeeded in “sunshine” into the nest.

    show more attractive prospects for the industry.

    Rizhao China is rich in resources, land surface solar radiation each year equivalent to 4900 billion tons of standard coal, the country 2 / 3 of the land area of more than 2200 hours of sunshine in, if all of these solar energy for electricity generation, which is equivalent to tens of thousands across the Three Gorges Power Station.

    Quartz sand resources in China is a big country, about the world’s production of metallurgical-grade silicon material of the 1 / 3. Quartz sand is the production of polysilicon raw materials, and polycrystalline silicon solar PV cells is the most critical raw material.

    In addition to resources, China’s “sunlight industry” also has broad market prospects. At present there are about 26 million of China’s population without electricity, to solve this problem, mainly by the development of renewable energy, especially solar energy photovoltaic power generation system.

    Tempting cake attracted the attention of investors.

    Silica - crystalline silicon - silicon ingots (silicon rods) - silicon - cells - cell module, in this solar energy photovoltaic industry chain, China’s enterprises are in a battery and battery-chip modules for the end of the main products c1295 battery,dell gd761 battery,dell kd476 , which entered the low threshold. Thus, even clothing companies are looking at solar energy photovoltaic industry is full of investment in a non-rational impulse. “Two engineers, coupled with 50 million yuan, will be able to engage in a solar photovoltaic plant,” the joke of the industry experts shows helpless.

    It does not know that the announcement came Shi Zhengrong does not belong to the whole industry. “Sunshine industries trip” filled with the same difficulties and frustrations.

    Technology is a rigid constraint. Polysilicon control of the lifeblood of solar photovoltaic industry, the core technology to produce a few multinational companies are monopolies. The world’s top 10 multinational companies accounted for the global market share of 85 percent, virtually controls the high-purity polysilicon production and sales joint venture or cooperation does not.

    Due to the lack of key technical support, although our country has an abundance of silica sand resources, but only one U.S. dollars per kilogram price of a large number of quartz sand will be exported to foreign countries, and then tens of dollars per kilogram price of imported processed from quartz sand of high purity crystalline silicon! “90% of quartz sand exports, imports 90% of the polysilicon,” This is the solar photovoltaic industry in China had to face the situation.

    Cost is another of China’s photovoltaic industry secret anguish, the data showed that the PV industry the impact of the rise of the international market price of polysilicon from the beginning of 2003 rose to 23 U.S. dollars per kilogram in 2005 at the end of 80 U.S. dollars per kilogram. “Topsy money should not even think about solar power on” is popular within the photovoltaic industry are also described from a side like this embarrassment.

    And cost is directly related to the scale. Data show that the current international economic scale photovoltaic industry for more than 1000 MW, while China’s largest photovoltaic —- Suntech, one of the scale of less than 200 MW.

    More serious is that in recent years, China’s solar photovoltaic industry 95% growth from abroad, especially in the current production capacity of the European demand is now also the European countries to develop photovoltaic industry is expected to achieve in 2007 about the basic between capacity and demand balance. If the pull of China’s domestic demand is not strong, then, China’s photovoltaic industry will be plunged into a crisis of excess.

    Right now, most of the concern is how the future of photovoltaic industry xps m140 battery,dell xps m1210 battery, dell 6y270 battery,dell 75uyf battery and the introduction of more and better “sunshine”?

    I rely on technology. “Over silicon for King”, which is the consensus of photovoltaic industry. Chain of the world photovoltaic industry is showing the trend of upper and lower opening, a number of silicon ingots and silicon wafer manufacturers have begun to set foot in the field of battery manufacturers. Let no doubt that PV companies in China face more severe challenges, in which case, the Chinese PV companies in order to grasp the initiative in development, independent innovation has become China’s photovoltaic business to survive, the only option for development .

    Second on the scale. “King of the middle class”, said that the scale effect. For small scale industries located in low-end chain of the status quo, the state should step up to support the photovoltaic industry development. Data show that in the early stages of development, all countries of the European photovoltaic industry to support the development of policy, such as Germany to raise funds to build large-scale adoption of solar power field, encourage private purchase of photovoltaic power generation systems, in Germany last year added 600 megawatts of solar power generation volume, measured down to spend more per month per € 1 only. For China’s national conditions, the industry suggested that the focus of the state can do to support several large-scale PV companies to extend latitude d820 battery,dell latitude d830 battery,dell latitude x300 battery the industrial chain, cultivating industry flagship.

    Renewable energy policy incentives and expansion of solar energy industry

    In new renewable energy policy incentives, China’s domestic supply chain in all areas toward the expansion of solar power in the direction - of polysilicon feedstock, wafer, cell and module. Investment bank Piper Jaffray analyst Jesse Pichel said in a report, China last month promulgated a renewable energy project involves 3.5 billion U.S. dollars of investment dell latitude d510 battery,dell latitude d520 battery,dell latitude d600 battery, designed in 2010 in the domestic solar power generation capacity to 500 megawatts. China also plans to solar power by 2020 will amount to 3,000 megawatts in 2050 to 6,000 megawatts.

    “In China, promulgated in February of renewable energy plan under the impetus of China’s solar energy needs are expected to be substantial growth over the next few years.” He said, “apart from less than 200 dollars a month in labor costs, China’s solar energy company may also be lower because the cost of management, research and development costs and external costs to benefit. ”

    According to the analyst, by 2008, China’s total module production capacity from 450 megawatts (MW) increased to 1,200 MW, the domestic solar cell production capacity increased from the current 200MW to 1,200 MW. 2005 China wafer capacity of 100MW, is expected to grow in 2008 to around 800MW, mainly from the signing of polysilicon supply, as well as contracts for the supply of a large number of polyethylene.

    He said that China’s solar manufacturing equipment industry will also expand. At present, the three Chinese polysilicon manufacturers monopolized the domestic market, but it is still a shortage of supply of material.

    “By 2007, Sichuan Xinguang silicon industry is still at an early stage of production and construction, planned in 2008 to 1,250 tons of annual production,” Pichel said, “LSCS current annual capacity of 300 tons, production capacity in 2007 reached 1,000 tons. Another year the current ESM about 100 tons of production capacity. “polysilicon high price to 200 U.S. dollars per kg, most solar manufacturers can accept the OEM dell latitude d610 battery,dell latitude d620 battery price is about 170 U.S. dollars per kilogram.

    Hydrogen bus speed of 80 kilometers at present to accelerate the research

    “51″ period, a new type of blue and white city bus, quiet park in Shanghai industrial zone Fengxian base of hydrogen fuel cells, hydrogen as the Shanghai section of a bus, which had been in April in the safe operation of more than 3000 kilometers, hydrogen fuel cell system is still very healthy. General Manager of Shanghai Dr. Hu Liqing told reporters, Do not “drink” is hydrogen, this bus can reach a top speed of 80 kilometers, driving mileage continued to reach more than 300 kilometers.

    The first hydrogen bus in Shanghai a run, only to speed up the Shanghai R & D of new energy automobiles in microcosm. Recently, the bear has 863 hydrogen fuel cell vehicle program, has a relatively strong R & D Shanghai-based enterprises and research institutions concerned, from the car into the bus, from the engine system research and development into the body, the major transmission systems, such as follow-up , new energy to the Shanghai Automotive is serialized, fast moving industry.

    Cars, the major mainstream hybrid vehicle research and development enterprises no moment to relax. General manager of Shanghai Volkswagen, revealed to reporters a few days ago Chih-Hsin Chen, Shanghai Volkswagen Touran models based on a hybrid platform development is actively in progress, this hybrid Touran is completely meaningless hybrid power system, the huge Touran body, only the 1.4L engine-driven fuel, motor vehicle, you can start to speed up or help when climbing, so that car can easily travel.

    Compared with ordinary Touran, the car can be more than 25% more fuel-efficient, even if the engine does not work on fuel, motor vehicles can also run 5-10 km, in accordance with the plan, in 2008, this will be a hybrid Touran production. Shanghai Maple is also the rapid development of hybrid research and development this year, with Shanghai Jiaotong University, Tongji R & D cooperation with the signing of the agreement, called a sea of 506 hybrid-type dell latitude d800 battery,dell latitude d810 battery is expected at the end of the Beijing auto show appearance, and in the next year small batch production before the Shanghai auto show.

    To better address the problems of urban public transport energy consumption and pollution research and development of new energy bus momentum letting a hundred flowers blossom there. Shanghai by the end of March this year into one of the first hydrogen bus is Shanghai Science and Technology in Jiangsu Golden Dragon Bus Company and the product of co-operation; SAIC shares in the new energy vehicle development schedule, its own research and development of hydrogen fuel cell bus is also will complete the development of a prototype vehicle.

Shanghai Automobile Gear Works in the R & D center, the future of hydrogen fuel cell system applies to the transmission models have begun to research and development, it will allow the future to drink hydrogen cars, and speed in time to start becoming more agile and smooth.

    Recycling used batteries contain a ton of great opportunities to sell 30,000 yuan

    From now on, when you throw away batteries weigh to weigh - and these things can be sold for money, but also expensive. According to yesterday’s Grammy from Shenzhen companies have found that the market price of scrap batteries as many as 30,000 yuan per ton maximum, is used several times the price of newspapers.

    Grammy is a precious metals production enterprises dell latitude d610 battery,dell latitude d620 battery, annual production capacity of ultra-fine cobalt powder, nickel powder 500 tons, 150 million yuan output value. A significant portion of its raw materials from used batteries. Production is now an annual 1500 tons of used batteries digestible. According to the company’s chairman, said Xu Kai, the battery can be extracted from the zinc, manganese, cadmium, nickel, cobalt, copper and other metal. Them from the market to buy these batteries have an average of 10,000 yuan per ton or so. If all of a lithium battery, to pay 30,000 yuan per ton; If nickel batteries, more than 20,000 yuan per ton. Ordinary alkaline batteries as a result of the value of lower price per ton between 3000-5000 yuan.

    Now there is no national comprehensive recycling system for used batteries. Grammy waste Recycle Bin from the acquisition of two used batteries, Hubei, Henan, Hebei more goods, accounting for more than 70%.

    Hsu Kai-hua said that the Shenzhen local cell recovery rate is not high enough. Statistical point of view based on an average, each person should use about a year the battery 4 to 50 grams each calculation, such as Shenzhen, the resident population of eight million cities, should be generated each year about 1600 tons of used batteries, which contain the business opportunities which great.

    He called for the establishment of the recycling system of used items so that items used to enter through the regular channels to deal with business in line with the qualifications. At the same time, enterprises and the public should also encourage the use of recycled products.

    Shenzhen has been dedicated to recycling used batteries. King, Futian District, in the farmers market to engage in quartz watch repair Chen told reporters, on every one around here, some of his acquisitions, foreign imports of certain high-end cell only a few grams dell latitude d510 battery,dell latitude d520 battery,dell latitude d600 battery, such as soy beans so much, but 0.3 yuan to the sale.
