Wind Power|Wind Power Energy

According to Danish wind energy author Uffe Geertsen, the idea of using wind power was inspired by the rural surroundings near the Danish Askov folk high school in the late 19th century where a teacher there, Poul la Cour, developed a hydrogen storage system that could store energy from wind. The power collected was used to electrify the lights in the school and eventually one of la Cour’s students, Johannes Juul, continued the research and created the first modern wind turbine with a capacity of 200 kilowatts at the Danish city of Gedser in 1957.

However it wasn’t until the first oil crisis hit in 1973 that the Danes realised the potential and importance of this new source of energy.

“The Danes realised that the oil-producing countries could politically use their oil to pressure the West,” Geertsen said.

It was from here that the Danish wind power genenerators industry grew.

Although it started as a blacksmith shop on the barren and windswept west coast of Denmark, in the small village of Lem, the company of Vestas is now the world’s leading producer of wind turbines.

It began producing wind turbines in 1978 and by the late 1990s it had over 22.1 percent of the global wind power measured in megawatt.

In 2004, Vestas merged with NEG Micon, Denmark’s second-largest wind turbine maker, to form the world’s largest wind turbine company with the lion’s share of more than 32 percent of the global market.

“Growth and reducing your energy consumption is possible. Since 1980, Denmark has had an increase in its economy by about 80 percent. At the same time, our energy consumption is more or less stable, and our carbon dioxide emissions have also been more or less stable,” Lykke Friis, Denmark’s climate and energy minister, told Xinhua during the Global Green Growth conference held last month in Copenhagen.

“It is possible to do both and that is the core lesson one can learn from Denmark. We need to transform and adapt to more low-carbon growth.”

In 1989, China’s Xinjiang Goldwind Science & Technology Company bought 13 150-kW wind turbines from Denmark. It has since grown into one of the largest wind turbine producers in the world, accounting for 7.2 percent of the world market, a report from consulting house BTM Consult showed.

Vestas opened business in China wind turbines in 2006, and there are currently six production facilities there. In its 2009 annual report, it hailed China’s great potential in wind power development.

It has increased investment in China to more than 3 billion yuan (about $439 million), while China became Vestas’ second largest market worldwide in terms of delivered megawatt capacity in 2010.

Vestas CEO Ditlev Engel recently also called for more small wind turbines policy support for clean energy among the G20 countries to combat climate change and generate more green growth and more green jobs.

“Creating green jobs on a massive scale is a two-way street. Give us the policy frameworks, and we will give you the results. We will make the investment, we will take the risks, and we will create the jobs,” he said.

In China alone, Vestas currently employs more than 2,000 people, and over 20,000 around the world.

Xinjiang Goldwind Science and Technology Co announces that one of its units has won a contract to sell wind power in Illinois in the United States, and it sees this transaction as a key step to tap the global wind power market.

Under the agreement, a wind farm to be built by Xinjiang Goldwind’s wholly-owned unit TianRun Shady Oaks LLC will supply 20 years of power to Commonwealth Edison Co from 2012, the Urumqi-based firm said in a filing to the Shenzhen Stock Exchange yesterday.

Construction of the 106.5-megawatt project, expected to cost US$150 million to US$200 million, will begin in 2011, the firm said.

“Winning the contract is significant step in the company’s strategy to go international after being listed in Hong Kong in early October,” Essence Securities wrote in a research report yesterday.

“Goldwind is expected to benefit from providing wind turbine and engineering services after transferring the power plant to future buyers, as this has been the usual case for its domestic operations,” it said.

Just a few years time, China has become the United States, Germany, Spain, after the world’s fourth largest wind power state. The wind power as a clean energy, one that in itself does not exist in excess, surplus wind power generators equipment. In 2005, the enterprise, the fan industry is undoubtedly a meat and potatoes. Because the country that year only 50 million kilowatts of installed capacity, and policy planning is to achieve 30 million kilowatts by 2020, installed capacity, which means 60 times the market has great development space. In terms of profitability, in 2007 the largest fan manufacturers – Goldwind machine’s gross profit margin reached 29%, that is, selling one million yuan worth of fans, basically you can earn 300 million is astounding wealth of myths continue to unfold, a large number of central enterprises, state-owned enterprises, private capital can no longer contain himself, rushed into the market will fall into place.

“As early as 2004, China embarked on a crazy fan industry to expand the road from 6 in 2004 soared to more than 70 now, more than 10 times the number of firms increase; wind power installed capacity from 2002 years ago 46.8 million kilowatts, the rapid development of the end of 2008 1,200 million kilowatts, an increase of 7 years, a full 25 times. the rapid pace of development of wind power, but also to the State enacted in 2007 to 30 million kilowatts by 2020, the long-term goals , just two years after outdated, because next year, the domestic wind power development is likely to break that goal. ” National Development and Reform Commission, said Li Junfeng, deputy director of the Energy Research Institute.

And energy in support of national policy against the backdrop of tight supply, the rapid rise of wind power equipment manufacturing industry, as many companies in the eyes of new economic growth point, the fan industry has become synonymous with the myth of wealth. However, the small wind turbines volume growth has not led the violent rise in quality, in fact, “technology hollowing out” has been the major drawbacks of wind power industry. In 2009, China’s wind power installed capacity of 13.8 million kilowatts new wind power installed capacity to overtake Germany to become the second, but in the process of joint development of new models continue to be each other design-based, China has not fully grasp the total wind turbine design, and most businesses do not have the core technology, only function is to act as assembly plants. This domestic wind power equipment enterprises, some enterprises in the fish in troubled waters, R & D capacity is weak, high profit-driven hastily wind power and other factors are inseparable, resulting in the purely generic products, wind power equipment manufacturing technology heavily dependent on the introduction of the defects become more prominent.

“Tarzan sit tight line business, a little second-tier companies waves, or third-line companies seeking to sell the joint, mainly on the core competencies in technology and large enterprises do not dare to directly touched.” Ningbo, a manufacturer of wind power companies Lei told small wind generators reporters that they plant currently has 200 watts to 20 kW wind turbine manufacturing capacity is being familiar with the companies considering joint ventures formed.

Long way to go for renewable energy development

China already has abundant renewable energy resource conditions and certain industrial base in recent years, rapid development of renewable energy in the stage, some of which technology has been at or near the level of commercial development, from the resources, technology and industry point of view, have the potential for large-scale development.

Government development of renewable energy given full attention, according to China’s development goals set in 2020, the proportion of renewable energy generation can reach more than 15% after 2040 up to 30% or higher level, has become an important alternative energy sources. After years of cultivation, renewable energy has begun in our country’s energy supply role to play in the future 5-10 years will be China’s wind power, photovoltaic power generation and biomass large-scale utilization of the initial stage, can seize the opportunity , lay a solid foundation, the rapid formation of the renewable energy market and industry is to promote large-scale application of renewable energy the key.

“In a sense, the wind has many advantages, but also a valuable source of income.” Kunming Hydroelectric Investigation Design Institute of Engineers Consulting Group, said Jiang Tao.

In short, the development of renewable energy in China has great potential and broad prospects, but the development of technology and industry are still many obstacles to the development of wind power industry can be described as long way to go, need the government’s active support, but also need industry, research institutions, etc. sustained community efforts.

December 7, Hubei Lichuanqiyue wind farm to the final commissioning. The wind farm is listed as one of the top ten wind farms, is supported by the state development of renewable clean energy projects in three phases, with total installed capacity of 150 MW. One of the installed capacity of 49.3 MW phase of the project, totaling 850 kW wind turbines installed 58 sets of total project investment of about 5.6 billion, is expected to be completed mid-grid.

It is understood that wind energy as a clean, renewable energy, more and more world attention. Yun huge amount of its global wind energy is about 2.74 × 109MW, of which wind energy can be used for the 2 × 107MW, more than the earth can be developed using the water volume 10 times bigger. Wind has long been used – mainly through the windmill power to pump water, grinding, etc., and now, people are interested in how to use wind to generate electricity. As of December 31, 2009, China installed capacity of over 1000MW of wind power accumulated over nine provinces, of which more than 2000MW of 4 provinces, namely Inner Mongolia, Hebei, Liaoning and Jilin

Shaanxi no history of wind power in the November 20 was rewritten. That day, State Power Shaanxi Traditional food groove Dingbian first wind turbine wind farm success and power generation, this new investment projects with the energy industry means that the first wind farm in Shaanxi Province was put into operation.
In fact, when one fan rotation, Shaanxi Province, a large number of wind generators manufacturer related industries have been “Follower of fashion.” Expected value of wind power equipment manufacturing industry will exceed 100 billion mark, a new bright spot of economic development of Shaanxi.
December 7, reporters came to Xi’an, China Economic Net Gold Wind Technology Co., Ltd., where one of the busy, the workers are working overtime, at full capacity to ensure that the order be completed on schedule.
As a key equipment manufacturing enterprises in Shaanxi Province, Xi’an Golden Wind Technology Co., Ltd. with an annual output of 200 megawatt-class wind turbines and the production capacity of 1,000 generators. Its main product is proprietary, the international leading level of 1.5 MW, 2.5 MW direct drive permanent magnet wind turbine, and will be based Jingwei Metro wind turbine generators manufacturing base gradually building measuring and testing centers and spare parts logistics center.
Little is known about a few months ago, the company even if there are orders, but also not so full capacity. Today, orders, such as flying like snowflakes, and even the maximum daily output of up to 6 units, “the year 1000 we will achieve megawatt-class wind turbine production tasks, to accomplish such a task is not anticipated.” Deputy General Manager of Xi’an Goldwind Zhang Liang said.
“Our wind turbine is to stop the production of transport processes, to produce the number of how many will Sinotrans, otherwise it will generate a lot of backlog can not result in our production.” Zhang Liang told the China Economic Net, Goldwind production of wind power equipment – direct drive wind turbines manufacturer, each product up to 4.98 m in diameter and weighs 45 tons.
As the market continues to improve, Shaanxi wind power equipment  generators industry has become increasingly mature. Ming Yang, Guangdong whole production wind power company already has a production base in Xi’an, an annual output of 150 MW of wind power production capacity of machine; Xi’an Golden Wind Technology Co., Ltd. has formed an annual output of 200 MW wind power machine The production capacity; Xi’an Research Institute of Marine Engineering Co., Ltd. the first 1.5 MW wind power machine has been offline Follower of fashion “

Samsung Corporation Inc. and the Ontario Provincial Government of Canada issued a statement, announced that Samsung Corporation will build a wind turbine manufacturer in the Windsor plant. This will create 300 local manufacturing jobs and 400 indirect construction and service industry jobs.

Windsor is Canada’s highest unemployment rate in the city. Francis said Windsor Mayor, Samsung Corporation Company in the end is to build a new plant, or use an existing vacant plant questions to the end of this year will be announced.

Canadian Energy Minister Brad Duguid said the reason Windsor is selected not only because it has access to other Canadian provinces and the northeastern United States and convenient road, rail and shipping, but also because the region has a relatively skilled labor force in the automotive design and manufacturing skills.

2014 Ontario plans to create 50,000 jobs in the green energy sector and stop the use of coal energy.

Wind the engine will arm (hereinafter referred to as “wind motivation”) associated with the wind  generator can be formed direct drive, semi-direct drive, with gear boxes and other forms of wind turbines, each equipped with air can be a motive, two or more generators. Wind motivation used in wind power generation will cause a significant impact on wind power, mainly in the following areas:
1, the motivation for the work of the sail the wind at zero to the maximum working area can be adjusted between, in the grid is running, except under the wind conditions on wind turbine automatically adjusted to maintain a relatively stable power output and reduce the impact on the grid, but also can flexibly adjust the dispatching instruction to meet the power requirements for wind farms, wind turbines can not be resolved to conduct a comprehensive scheduling problems, truly realized the power of wind turbine operation and change the wind turbine in the nature and status of the grid, and then realize a large-scale wind power grid wishes.
2, according to the motives of the structure and characteristics of the wind, its wind speed to work effectively a large range of low rated wind speed, the equivalent number of hours to increase electricity generation, which now makes some low-velocity wind can also have a use value, and then expand the wind energy area, increasing the total amount of wind resource utilization.
3, due to lower wind speed rating of motivation, small wind turbines according to the frequency distribution of wind we can see that the output power generators can remain stable in a wide range, and network will be more stable; the same time, the equivalent units increased use of time, power generation increased, reduce the cost of electricity.
4, the wind is the motive power output using multi-axis, can be connected to multiple motors, making it easier for manufacturing large-capacity stand-alone. The motor is running, can be a single work, but also combinations of two or more grading work, which can make full use of wind energy resources, but also make the grid more flexible scheduling; the same time, installation of generators and other major components At the bottom, and can be assembled at the scene, making the equipment installation, maintenance, operation more convenient, easier, wider temperature operating environment, installation, maintenance, operation and lower cost.
5, the wind lifted bulky motivation propeller, making the transport of wind power equipment simpler, easier, lower transportation and installation costs, but also expanded the use of wind turbine installation and range areas, thus expanding the wind resources use area.
6, for these reasons Article 3,4,5, wind farm construction costs, operating costs will be lower, making the lower cost of power generation, thereby increasing the capacity of the purchase price, can meet the low-cost green energy requirements, but also improve the wind farm investment.

Siemens established its first Chinese limited company of blades production for wind turbines Tuesday in Shanghai, according to the China Business News (CBN) Wednesday.

With a total investment of 35 million euro ($45 million), the wind turbine manufacturing plant in China is expected to produce over 600 units of blades for wind turbines yearly, with the first to be out still in 2010- a 12-tonner.

Siemens has recently hired 120 employees,and the number will extend to 210 next year, said the report.

In China and Poland, people to the windmill edge wedding photography. British “Economist” Global Wind Energy Council official quoted the words of Steve, to refute those who believe that windmills not pretty, especially those so people who oppose the offshore wind power.
In the U.S., because the Kennedy family and other prominent opposition figures – windmill to these rich people’s beach Summer homes created a “visual impairment”, the Government had to modify a 10-billion offshore wind power construction program, the number of wind turbines from 170 were reduced to 130, windmill construction group will be more elongated strip 30 kilometers away from the town’s waters. The plan in April approved by the U.S. President Barack Obama, installed 468,000 kilowatts, is expected to become the first U.S. offshore wind power station.
Obviously, for China, a developing country’s growing energy consumption, on the windmill is “unsightly” discussion is clearly too extravagant. Moreover, offshore wind power generation has not refuse, without water, almost no land, and many other advantages. We are more concerned about is: How far offshore wind ionization we?
In September the end of the first round of one million kilowatts of domestic offshore wind turbines concession in the coastal Jiangsu Province, Sheyang, Dongtai, Dafeng 4 100 megawatts of offshore wind farm concession projects announced. This indicates that the Chinese offshore wind power project has been to promote demonstration projects into the commercial stage.
