U.S. Interior Department has repeatedly said, offshore wind turbines offshore to provide sufficient electricity to meet current U.S. electricity demand. Relatively shallow waters of the sea is the most easy to erect wind turbines, technically the most feasible site, Salazar said, only the use of these waters, small wind turbines can meet most U.S. coastal states at least 20% of electricity demand. Salazar released a report completed by the Ministry of the Interior Mineral Resources Authority’s report in detail for the U.S. Outer Continental Shelf oil and natural gas and renewable energy development potential.

Atlantic coast of the United States the greatest potential for wind power, according to the report estimates that can produce one billion kilowatts of electricity, enough to meet U.S. 1 / 4 power needs. The report also noted that although the California coast, including wind power, including the Pacific coast has great potential, but in deeper waters, wind turbines may face increasingly serious challenges.

It is predicted that the U.S. offshore wind power potential of up to 400 megawatts. But analysts believe that this is only theoretical figure, if all constraints into account, including economic feasibility, wind conditions, the United States can large-scale commercial offshore wind power generation capacity of approximately 127 million kilowatts.

U.S. offshore wind power development goals first lock the shallows, and then developed into deep water, mainly in a unit capacity of 5 MW or more fans. According to reports, the U.S. set a goal that by 2012 the price of four shallow 5 cents / kWh. Currently, the U.S. is studying deep-water technology, as technology advances, the cost will also be well controlled to ensure the healthy development of offshore wind power.

U.S. media believes that oil prices in the period, on behalf of the Republican Party has been vigorous development of oil and shouting, so offshore energy problem has become particularly urgent. Critics also accused Obama and Salazar deliberately delaying new oil and gas drilling. Oil drilling proponents say the latest estimates of offshore energy can be found in more offshore oil potential. And Salazar said that the future of offshore wind power is the protagonist. He promised that as soon as possible to develop offshore wind power development of guidance and regulations to complete the United States during the Bush administration failed to complete the work.

CSR motor stators made 1.5MW wind power generators was first proposed in the international arena and increase the use of mica tape around the bag film sintered wire, coil insulation to improve strength and moisture resistance; and the first in the overall immersion and the use of large motor rotating baking technology.

Complete motor vehicles in recent years, Southern Science and Technology, “October” major scientific and technological support projects and over 1.5MW wind turbine permanent magnet synchronous development and industrialization, Hunan Science and Technology Department and the major science projects over 2.0MW direct drive permanent magnet wind generating research, and with the domestic wind power industry giants cooperate to form a national Goldwind Wind Engineering Research Center Motor Research. Quickly and successfully developed series of asynchronous, double-fed, direct-drive permanent, semi-direct drive permanent magnet wind generators, high-speed permanent magnet wind generator, wind power industry of China has made great contributions.

In the field of wind power, motor vehicles licensed patents south 12 to complete the identification of two scientific and technological achievements. “Megawatt-class wind turbine permanent magnet synchronous industrial project” successfully passed the National Development and Reform Commission and acceptance of new energy tech industry. “2 MW to the development of permanent magnet synchronous generators and industrial projects,” won first prize for scientific and technological progress in Hunan Province, Zhuzhou Science and Technology Progress Award. 2008 Beijing Olympic Games, provided by the CSR 33 sets of 1.5MW motor direct drive permanent magnet synchronous wind turbine wind farm in Beijing Guanting Green Olympics in China has made a significant contribution to the project.

Motor vehicles in Southern China has become the largest small wind turbine production base, the National Standardization Technical Committee members of the wind mechanical units.

Due to the over draining of water, more than 10,000 mu (667 hectares) of saltwater lakes and 1,000 mu of freshwater lakes in the oases have dried up, he said.

The water level of the Yueya Spring, which is a crescent-shaped lake and also a famous scenic spot in Dunhuang, has dropped from five meters to one meter in the past 60 years. Therefore, the government has had to encourage farmers to plant less water-consuming crops and reduce the wind power generation area of farmland to conserve water, but the moves have hampered the development of the economy.

“Although technology and money remain challenges for Dunhuang to embark on the new energy economy, its development path makes full use of its own advantages and will benefit the local economy and environment as well,” said Xi Wenhua, an official with the United Nations Industrial Development Organization.

Dunhuang boasts abundant renewable resources, as it receives 3,257 hours of sunshine as well as possessing rich wind resources and spacious wastelands, according to the small wind generator city government’s data.

More than 3,500 square kilometers of wasteland on the edge of oases in the city can be used to build solar and wind energy facilities, with the potential installed capability reaching 100 million kilowatts, according to the data.

China’s first photovoltaic power station with a net capacity of 20 megawatts has been completed in Dunhuang, and the construction of an even larger one with a capacity of 100 megawatts is under way in the city.

To meet its obligations to combat climate change and wind turbine generator adjust the domestic energy-consumption structure, China has accelerated its development of renewable energy.

Earlier this year, Liang Zhipeng, deputy director of the Department of New Energy and Renewable Energy of NEA, said China plans to build pilot zones of microgrids in regions with rich solar and wind resources and establish 100 pilot cities of new energy development from 2011 to 2015.

Wind power is the world’s fastest-growing new energy, offshore wind represents the current wind power technology, the highest level, requires equipment, high reliability, easy installation, easy maintenance, great size of the market, the risk is high, equipment by the countries concerned, are set off investment boom. Currently more than 100 countries and regions began to develop wind power, concentrated in major markets in Europe, Asia and North America.

According to “five” renewable energy plan, wind power renewable energy as an important new force continue to develop, plan in 2015 China’s offshore wind power installed capacity of 500 million kilowatts, planned offshore wind power by 2020, 30 million kilowatts installed capacity .

Offshore wind power the fastest-growing New England in 2009 to achieve installed capacity of 306,000 kilowatts, a total installed capacity of 894,000 kilowatts in 2010, the British offshore wind power capacity exceeded 100 million kilowatts. As at the end of 2010, China’s offshore wind power installed capacity of only 142,500 kilowatts in 2010, the world’s offshore wind installed capacity of 3.5 million kilowatts of electricity accounts for only about 4%.

China stabling of offshore wind power project in Shanghai East Sea Bridge, 100,000 kilowatts project, Jiangsu Dafeng intertidal 300,000 kilowatts last year, the wind turbines government first round of demonstration projects and 100 thousands of Wahe upwind power tender. Domestic and foreign professionals believe that by 2020, the only country outside Europe will be a rapid development of offshore wind power market, especially the next five years, China’s offshore wind power will enter a period of accelerated development.

It is reported that 100 thousands Wahe tender upwind power project development will be completed in four years, for our future large-scale development of offshore wind power, the development of tariff policy and management mechanisms useful to explore.

It is understood that the first half of next year the National Energy Board may also start the second round of offshore wind power concession projects, bidding to be the size of 200 million kilowatts, compared with the first round of bidding double. Some experts assert that with the accelerated development of offshore wind power, wind power will become the coastal provinces and cities along the main source of future energy supply.

According to Deputy Chief Engineer of Water Water Planning and Design Easy Yuechun introduced the National Energy Board is organizing the provinces, autonomous regions and municipalities to carry out offshore wind power planning, promote the construction of offshore wind turbine generator demonstration projects, focusing on development and construction of Jiangsu, Shandong offshore wind power base, promote Hebei, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi, Hainan and other provinces offshore wind power construction.

National Energy Board will organize relevant units in the summary of each province offshore wind power planning based on the results, considering the wind farm project the progress of preparatory work, construction and power-consumptive market conditions and other factors, the preliminary work program effective arrangements to implement the wind electricity planning objectives.

China’s offshore wind resource is abundant, especially the eastern coast of Jiangsu coastal beaches and offshore wind power has developed very good condition, large-scale development of the basic conditions have been met. According to preliminary results of detailed investigation of wind energy resources, China Meteorological Administration, China’s measured depth of 5 meters to 25 meters within the coastal zone line, 50 meters above sea level, wind power can be installed capacity of about 200 million kilowatts, 70 meters can be installed capacity of about 500 million kilowatts.

In addition, China has initially with the offshore wind power design, construction and equipment manufacturing capacity, development and construction of a number of offshore wind power demonstration project, Hua Rui, Jin Feng, Shanghai Electric and other eight plant units with a total of 54 offshore wind power operating results for future large-scale development of offshore wind power has gained experience and training of a professional team, such as CCCC Third Harbor Bureau, Nantong ocean water to build more than 10 involved in the construction of offshore wind power company, for the development and construction of offshore wind power to lay a solid foundation.

Developing countries invested more in renewable energy than their developed counterparts for the first time last year, according to a report commissioned by the UN Environment Programme (UNEP).
Investment in large-scale renewable projects such as solar and wind power generation farms totalled $72 billion in the developing world, outstripping industrialised economies by $2 billion in 2010. China accounted for 70 per cent, pumping $50 billion into clean energy projects, mostly in the form of wind technology. Excluding the BRIC countries, the Middle East and Africa saw the biggest jump in investment, doubling to $5 billion.
Udo Steffens, president of the Frankfurt School of Management that collaborated with UNEP on the report, said the trend was likely to continue: “The investment activity in the developing world is not only leading to innovations in renewable energy technologies” he said. “It home wind turbines will also open up new markets, as first mover investors are facilitating a range of new business models supporting entrepreneurship in the developing world”.
With Chinese investment soaring, Europe may be in danger of falling away. Chinese companies have leapfrogged the west as leading producers of solar panels and wind turbines over the last two years but positive growth is not matched on the continent, where investment in large-scale renewable projects was down 22% from 2009. In contrast to the developing economies, European green investment was concentrated on smaller scale projects such as rooftop solar installations in Germany.
However, in a record year for renewables, worldwide investment reached $211 billion, up a third on 2009. Green energy now accounts for over 5% of the world’s total power generation but is still below the targets of most developed nations. The EU has a base target of 20 per cent of total power generation from renewables by 2020.
The report also predicts further drops in the costs of solar and wind technologies. Wind turbine prices have dropped 18 per cent per megawatt in the last two years but the low price of natural gas continues to hurt the green sector. Competition from wind generators burning cheap gas contributed to a drop in clean energy share prices of nearly 15 per cent and M&A in the form of takeovers and acquisitions of windfarms, also fell 10 per cent in 2010.

Recently, the Chinese wind power equipment R & D and manufacturing leader Goldwind Science and Technology Co., Ltd. announced that the company’s first direct-drive permanent magnet 6.0MW offshore wind turbine generator prototype of the first half of 2012 and power generation, mass production in 2014 .
There were indications, 2015, China’s offshore wind power installed capacity will reach 500 million kilowatts in 2020 will reach 30 million kilowatts. Goldwind Chief Engineer Cui Xinwei that the unit will be large-scale offshore wind turbine development trends, 6 MW offshore wind turbine will power the future of the mainstream models.
Up to now, the wind technology has accumulated a certain amount of offshore wind turbine operation and maintenance experience. November 8, 2007, Goldwind developed Asia’s first Taiwan Strait upwind turbine 1.5MW direct drive permanent magnet in the Bohai Bay and network operation, since 2011, more than 98% availability. July 24, 2010, Goldwind Dafeng offshore wind power industry base a project put into production. Goldwind Rudong and sound of water offshore of a 2.5MW direct drive permanent magnet wind turbine and network operation is also nearly a year, so far running well, may have reached more than 95% utilization. Last October, Long Yuan Electric Power co Goldwind winning the first round of national offshore small wind turbines concession bidding Dafeng 20 million Wahe upper hand electric project, the successful direct-drive permanent magnet unit of 2.5MW offshore wind turbine, the current project is progressing well , the second half of 2013 and net run.

China wind power equipment manufacturers are actively developing large-scale wind turbines, promising to promote the development of offshore wind power.

30 pm, Xinjiang Gold Wind Technologies AG, the media communication will be held in Beijing, announced that the company’s first direct-drive permanent magnet 6 MW offshore wind turbine prototype of the first half of next year, and power generation, mass production in 2014.

Goldwind Chief Engineer Cuixin Wei said: “The large-scale offshore wind turbine will be the trend by increasing the unit capacity, we can enhance the unit wind farm construction in the proportion of the cost, effectively reducing the total offshore wind farm construction costs. “However, compared with onshore wind farms, offshore wind farm capacity of the same capital investment of about 40% higher.

Recently, the United States electric power technology Co., Ltd., Shanghai Electric, CSIC (Chongqing) Sea Windpower Equipment Co., Ltd. and other companies have said will be the year or early next year at sea off the assembly line for the 5 MW or 6 MW wind turbine. Last October, China’s largest wind turbine manufacturer, Sinovel and XEMC Limited were off the assembly line manufacture of self-developed 5 MW offshore wind turbines.

Industry experts believe that China’s wind power equipment manufacturing companies to launch such a large fan-intensive, marking China’s offshore wind power  generators has entered the era from 3 MW 5 MW and 6 MW of the transition. Experts point out that offshore wind power capacity must be in stand-alone unit total installed capacity of wind farms have reached a certain scale before profitability.

Liu Qi, deputy director of the National Energy Board recently said that the future maritime unit capacity should be developed gradually from 3 MW to 5 MW or more above the intertidal zone unit capacity of the project should not be less than 2 MW.

Offshore wind power has rich resources, hours of high electricity use, not suitable for large-scale occupation of land and development characteristics. Rich in wind resources offshore China, after a preliminary assessment, China’s offshore wind energy resources can be developed shallow waters about 200 million kilowatts.

China Renewable Energy Association Committee Vice Chairman Shi Pengfei that, with high-speed land-based wind power development, the Chinese offshore wind power is still at an early and exploratory stage, Chinese technical support for offshore wind power is relatively weak.

In the offshore wind farm construction, China has built offshore small wind turbines project 138,000 kilowatts, accounting for total installed wind power capacity of less than 1% of the world’s offshore wind power installed capacity of around 4%. Have been incorporated into national macro-vision of the project there are 2.588 million kilowatts.

Liu Qi said, “five-second” period, China will be “safe, positive” to promote offshore wind power development, and “the scale of development, advanced technology,” China’s offshore wind power is one of the principles of work. National Energy Bureau, China’s offshore wind power development goals for 2015 reached 500 million kilowatts in 2020 to reach 30 million kilowatts. This year, the National Energy Board will start the second offshore wind power concession projects tender preparation, tender is expected to be completed early next year, with a total construction scale of 1.5 to 2 million kilowatts.

China WindPower Group Ltd said on June 20 it had received the green light from the Hong Kong stock exchange to spin off and list its wind power tower tube manufacturing operations.

Via the move, the company seeks to focus on its core activities and to more efficiently allocate financial resources. China WindPower’s core operations include the development of wind farm projects and the provision of engineering and construction, operations and maintenance and other services to wind power facilities.

At present, two wholly-owned units of the company are in charge of its wind power tower tube business. The company plans to reorganize it so that its subsidiary Tianhe New Energy Equipment Ltd becomes the holding company. As part of the plan, Tianhe is to gradually expand its business to include solar power equipment wind turbines  manufacturing.

The spin-off and listing are pending the go-ahead from China WindPower and Tianhe’s boards.

Hands pinch, bamboo dragonfly into the sky. We are not familiar with this scene. Large model, you may not believe, today’s “Bamboo Dragonfly” has been transformed, can be used to generate electricity up. The High-Tech Expo at the current meeting, a group developed by Hangzhou Dazhuang bamboo composite wind turbine blades is especially attractive to the eye.

Currently, the production of domestic and foreign wind turbine generator blades typically use fiberglass or carbon fiber as the main material, which is a composite bamboo leaves in green, natural ecological materials – bamboo paddle as the matrix material.

Bamboo film to growth in southern China’s natural Chi bamboo as raw material, compared to traditional glass fiber reinforced blades with a simple process, performance, stability, ease of recycling and other advantages, we can directly reduce the cost of materials 25%, power generation efficiency is increased by 15%. Bamboo and recyclable bamboo film, breaking the glass fibers present status of high carbon emissions, development potential, which makes the production of bamboo composite material composed of a real wind turbine wind turbine green. Previously, using the bamboo composite wind turbine blades have been successfully installed in Hebei Zhangbei, while achieving grid. At present, the village has been famous with the wind power business, has begun the mass production and supply of bamboo sheet bamboo composites.

In similar enterprises in May last year, Shandong Century Gateway to the domestic production of the first 40.3 meters, 1.5 MW bamboo pieces Vaillant was born in the century, followed by a static load test and dynamic load test. After several design optimization, after 12 months, bamboo chip technology by China’s new energy certification authority, the indicators fully meet international standards. Currently, the small wind turbines century has produced bamboo Vaillant film 6, for installation of two generating units, will be held in Huaneng and Datang to hang up wind farms under test.

You can see, bamboo slice technology has already begun the process of marketization. In time, the development of scientific research or for the market development of wind power into the new growth point.

The 32-story turbines of the Jersey-Atlantic Wind Farm have so dramatically changed Atlantic City’s skyline – perhaps more than any casino could – that tourists haven’t stopped asking questions about them since they went up five years ago along a back-bay salt marsh.

Some casino hotel guests are so fascinated that they small wind turbines ask for rooms with a view of the five delicate fans, resort operators say.

So the Atlantic County Utilities Authority is cranking open the security gates at the Route 30 wastewater-treatment facility that houses the turbines for twice-a-week tours in June, July, and August.

The tours were offered by appointment only last summer – to see whether anyone was interested. This year, they are scheduled for noon Mondays and Fridays, no appointment necessary. About 15,000 people a year – mostly school groups – had previously visited since the wind  turbines were erected.

The tour covers the industrial-looking grounds of the wastewater-treatment facility, where a rotten-egg smell emanates from the containment basins and water-clarifying stations. But standing at the concrete base of one of the massive turbines gives visitors a better understanding of just how this operation saves 24,000 barrels of crude oil a year with the hybrid energy projects in use here.

While visitors can’t go inside and climb the winding staircases of the 385-foot carbon-steel structures, they can get close enough to the bases to hear the unique “whoosh” of the 120-foot blades.

Most of the time the turbines are silent sentries, turning between 10 and 20 revolutions per minute, and when the wind averages about 15 m.p.h., the tips of the blades go as fast as 120 m.p.h., said Chris Harris, director of wastewater operations for the plant, who led a recent tour.

“This entire plant, with the wind turbines generator as a centerpiece, is actually the largest demonstration of hybrid energy in the U.S.,” Harris bragged as he showed the group how the wind energy, combined with a solar array on the site, supplies more than 60 percent of the electricity required to operate the plant.
