Participating groups in foreign countries, there are many works in the bright spots. India’s English media from a contestant on the concept of the school a “new concept car.” He advocated the use of electronic devices, save fuel and reduce pollution. For example, a red light, the car will automatically turn off the engine to save energy. Another example is installed in the car under an optical sensor, a traffic signal in the vicinity of any (especially more than 60 seconds of lights) lights installed underground. Automatically open when the red light, green light is automatically shut down. The project also demonstrates the car’s engine before the traffic lights to be turned off and be activated when the vehicle traffic to keep a safe distance, the driver only need to control the steering wheel.
Limited liability company by the German wind turbines manufacturer Enercon’s E-126 wind turbines, is currently the world’s largest wind turbine (see Figure 1). The unit’s rotor diameter of 126 m, about 413 feet, was previously installed capacity of 6MW of the E-112 model of the improved version. The company was established in the German city of this unit Emden, and its energy storage system of the unit test several times. At present, the first two batches of sample respectively in November 2007 and September 2008 to complete the installation. However, E-126 unit installed capacity is not yet clear, an argument remain 6MW, while another way is 7MW or 20000000kWh / y.
Rotor speed 12rmp. The unit has several unique small wind turbines characteristics: leaves on the spoiler extended to the design hub as well as pre-cast concrete base (see Figure 2). Advanced hub height and blade profile is expected to exceed the performance of E-112. In addition, E-126 does not set the gearbox, so a direct drive turbine generators. Generators installed in the largest office space cabin.
Wind turbine generator contract prices show the price in 2010 compared with 2008, in the second half of 2010 and 2011 delivered the first half of wind turbine prices will continue to be significantly reduced. According to Bloomberg New Energy Finance (BNEF) recently published the third phase of wind turbines price index (WTPI) shows that this decline by as much as 15%.
BNEF analysis shows that in 2008 signed the delivery of the first half of 2009 the price peaked turbine generator sets, the price reached 1.22 million euros / MW. However, due to the financing of wind power projects, the current oversupply of global wind power market, making 2010 the second half of 2010, signed in the first half of 2011, the delivery of wind power contract prices have fallen, the average price of 1.04 million euros / MW.
In addition, the recent being negotiated in the second half of 2011, reported out a contract to deliver the same price, there is no signal that the recent price rebound fan signs. Here’s the price including freight, but does not include VAT and all other construction costs.
The main wind turbine generator buyers expect in 2010 and 2011, prices will fall further, decreases were 4% and 1%, while the expected price rise will occur in 2013.
BNEF the wind observation services manager William Young said, “wind generators never expected the price so low, but the current excess supply situation will continue for a long time. Of course, this is not the wind turbine manufacturers are willing to look at to, but the industry is concerned, this will increase wind power and natural gas, coal and nuclear power more competitive.
Difficulties under the wind power industry will be how to achieve great development?
“Wind power industry based training to support the development of poor areas is a long-term goal, can be used as an obligation to implement, it requires effective legislation and policies to support industry. After re-address the issue of energy and environmental protection.” Long Yuan Electric Power Group Long Yuan Electric Power Group senior engineers YANG Xiao-sheng think.
In addition, due to the weak industrial base of wind turbines equipment, such as multinational brands in the technology to step up control on the Chinese side at the same time, research and development, procurement, facilities, manufacturing, marketing and other aspects have also strengthened the control of the industrial chain. “Of course, the domestic wind power companies, this is both a promotion, is also a challenge.” Association of Chinese Renewable Energy Professional Committee of Experts HE De Wind said.
Hunan Electric Group Chairman Jianxiong believe that this challenge is pioneering. He said that the time goes forward, non-renewable energy will become more intense; on wind generators, the power generation capacity is, the higher technology content, the lower the cost of wind power. The two eventually reach a balance point, wind power costs will be very close to or lower than current conventional power, wind power in energy supply and the role of reducing greenhouse gas emissions will become increasingly significant
Rigorous testing by the Texas Inspection and Quarantine Bureau after passing by the Hwa Ya Technology Co., Ltd. Ningjin County produced three sets of small wind turbines shipment exported to Italy, this is the first time, the city exported wind turbine products.
Wind energy as a clean, renewable energy, with a huge amount Yun, investment, safe and effective advantages, more and more attention around the world. The rapid development of wind energy products for the wind power provides a huge market, especially small wind turbines in Germany, Denmark, the Netherlands, Italy, the United States and other countries have great demand. Currently, our city has a Gateway to Texas century, Ning Jinhua Asian industrial production more than a dozen wind turbines, wind turbine blades and other wind power products.

In solar power, wind generators and other new advances today, many of the old life devices are constantly being green energy use by the concerned University of Leicester students TomBroadbent hotel shower in Yici whim, and fashioned this station Small four-blade turbines driven generators, the use of wastewater flows to generate electricity under the water.
According to Broadbent’s statistics, a 7-storey building after the installation of these units waste generator can save one thousand U.S. dollars per year of electricity. This water wind turbines phase generators have been a number of institutions, in the near future will enter the consumer market.
Jiaxing is located in Tongxiang City, United appropriate independent research and development of wind energy equipment Co., low-speed wind power generator , the technology to fill an international gap.
In the wind turbines industry, the average wind speed 3 meters per second is called the low wind velocity, wind speed in this wind turbine can not be generally normal power generation. And the company’s first low-speed small wind turbines have been settled in Ireland in April this year, low-speed wind, and create electricity 12 kwh per day of success, try being the best customers.
Recently, British researchers at the University of Edinburgh Institute of Foreign released the two C-GEN generators of the prototype. The latest research results will substantially increase the efficiency of wind turbines. This technology can enable a lightweight, direct-drive small wind turbine installations in place of the original complex transmissions. In addition, the device technology is simple, wear-resistant, easy maintenance. According to engineer, the new C-GEN technology allows direct drive 50% lighter than the original, This way will significantly reduce production and operating costs.
University of Edinburgh Institute of participation in C-GEN technical R & D, Dr. Miller spoke: “The technology to improve existing systems, make it easier to wind generator manufacture and reduces system weight and cost.” Some experts think that this technology will to make wind energy more affordable, efficient, and power enterprises to improve efficiency in the use of wind turbines, the technology eventually Samaranch reform the whole potential of the renewable energy industry.
m NextEra the next 20 years for data center power supply.
Less than 3 months ago, this Silicon Valley Internet wind turbines search giant just NextEra development and construction of North Dakota, two wind farms invested 38.8 million U.S. dollars, the two wind power generating sites for 55,000 household electricity.
Google senior vice president of operations Etzler (Urs Hoelzle), said the official blog, Google energy companies starting from July 30th’s Lova from NextEra wind to the proportion of pre-arranged to purchase wind power.
He also said: “Wind power generator will be so much into the company’s power supply portfolio is a tricky thing, but these power supply sufficient number of data centers.”
Google, through its charitable arm Google.org in addressing climate change has made some progress. This often made surprise at the end of 2007 the company had said that the next few years will invest in R & D companies and through its own production of cheap renewable energy.
Google’s energy sector was established in December last year, companies from the wholesale electricity market by the department to purchase a large number of renewable energy.
