06 九 11 According to the World Wind Energy Association’s (WWEA) half-year report
After a somewhat listless year in 2010, the global home wind generator industry has gained momentum during the first half of 2011.
According to the World Wind Energy Association’s (WWEA) half-year report, 18.4 GW of new wind turbine installations occurred during the first half of 2011, with 43.9GW expected by the end of this year.
China, USA, Germany, Spain and India combined account for 74% of global wind turbines manufacturers capacity; with China having an overall installed capacity of around 52 GW by the end of June this year. China added 8 GW in the first 6 months of 2011, a record according to WWEA.
The US market has had a particularly strong year so far, adding 2.252 gigawatts of wind power capacity between January and June, 90% more than the same period last year.
Canada added 603 MW during the first half of 2011, with the province of Ontario the leading region due to favourable government policies.
The number of countries now using wind power has grown from 83 to 86, with Venezuela, Honduras, and Ethiopia the latest nations to be harvesting wind energy.
By the end of June, global wind capacity had reached 215 GW, representing growth of 22.9%. WWEA estimates total installed wind capacity by the end of 2011 is to reach 240.5GW, enough to provide for almost 3 % of the electricity demand all over the world.
“Although the deployment of the wind power generators worldwide is again speeding up, we still see relatively moderate growth rates, compared with previous years,” said Stefan Gsänger, WWEA Secretary General. “On the one hand, it is very encouraging that new countries are coming up. On the other hand, we need more support on the national as well as on the international level.”

10 八 11 U.S. offshore wind power development of the high cost constraints
Virginia Bureau of offshore wind power development has issued a survey report, the U.S. offshore wind power generation costs are high. The report cites the U.S. Department of Energy data indicate that the U.S. offshore wind power generation total cost of $ 243 per 1000 kwh, while the hair as much power, onshore wind power cost is only $ 97.
Moreover, compared with other forms of power generation, offshore wind power costs have to be much higher. According to the report, the cost per 1,000 kWh of electricity, solar photovoltaic power generation system for $ 211, $ 125 gas turbine power generation, nuclear power is $ 114, biomass power generation is $ 113 to $ 109 coal-fired power generation, combined cycle turbines power is only 66 dollars.
“Offshore wind power is a technically feasible power generation mode, and now we need to do is reduce costs.” Domini U.S. energy company Renewable Resources Program Director Guy Chapman said that with the positive development of Europe can renewable power, and the new wind farm development to deeper waters, the global cost of offshore wind power project gradually increase, and thus make the United States the cost of offshore wind power project increases.
However, the Virginia Board of offshore wind power development report also said that with offshore wind power industry in the United States has evolved in cost reduction is also possible. For an emerging industry, offshore wind power would have to be a relatively long period of development. U.S. industry insiders believe that the future of offshore wind power industry can develop more quickly, is still largely depends on government policy to support efforts.

13 七 11 China has grown into a global power in renewable energy
With Japan looking to hedge its bets on nuclear energy by exploring other renewable energy sources, Chinese companies are eagerly vying for a seat at the table, anteing up its leadership in wind and solar power technology.
While Japan has built 54 nuclear reactors, China has grown into a global power in renewable energy, although its domestic market is fraught with problems. China also has 13 nuclear reactors and is building 28 more.
Top manufacturers such as Goldwind Science and Technology Co. and Yingli Green Energy Holding Co. are looking to break into the Japanese market as wind turbine generator and solar power gets renewed attention following the accident at the Fukushima No. 1 nuclear power plant.
The Chinese government has committed public funds to improving the international competitiveness of manufacturers of renewable energy facilities.
The government adopted a policy of encouraging the use of local products until it was abolished in February in the face of criticism from the United States, who felt it was giving an unfair advantage to Chinese firms. Goldwind Science and Technology has produced 7,800 wind turbines, or triple the number installed in Japan, since it was established 13 years ago.
The company, based in Urumqi, Xinjiang Uighur Autonomous Region, ranks among the world’s five top makers of wind power generation facilities.
It has accumulated technologies by acquiring a German company and now exports to the United States.
Yingli Green Energy Holding Co., a major wind generator manufacturer of solar panels established in 1987, has increased its presence in European markets, working with a German partner.
The company, based in Baoding, Hebei province, operates offices in the United States, Germany, France, Italy and other countries.
Its credo is to provide “green energy affordable to the home wind turbines public.” To raise its profile, the company has become an official sponsor for the 2014 World Cup in Brazil, following upon its sponsorship of the 2010 World Cup in South Africa.

04 七 11 China will expand its offshore wind power installed capacity to 5 GW
According to Chinese Renewable Energy Industries Association, China will expand its offshore wind power installed capacity to 5 GW by 2015 and 30 GW by 2020.
CREIA forecast came during the announcement that Offshore Wind China 2011, the largest industrial seminar and exhibition of offshore windmill power in Asia is being held from June 15 to 17 in east China Shanghai City.
According to Mr Qin Haiyan secretary general of the China Wind Energy Association, Offshore wind development in China remains in the early stages due to complex operating environments for offshore turbines, high technological requirements and construction difficulties.
In 2009, China had only 63,000 kilowatts offshore wind turbines installed, about 21% of the newly installed offshore wind power in the United Kingdom the fastest growing country of the year. The year 2010 marked the start of China offshore wind power sector transition from research and pilot projects to operational wind farms.
In March 2010, Mr Shi Lishan deputy director of the New Energy and Renewable Energy Department of the National Energy Bureau said top priority would be given to developing offshore mini wind generator projects in the course of boosting the flourishing wind power industry.
In June 2010, the first stage project of East Sea Bridge Offshore Wind Farm went into operation in Shanghai. Totaling 102 MW, it is China first large-scale offshore homebuilt wind generator farm located to the east side of the Shanghai East Sea Bridge. It comprises 34 units of 3 MW Sinovel turbines.
Offshore wind power construction is a priority in China this year. In January, the NEB said China would kick off construction of 1 GW offshore wind power projects in 2011. The public tender for the 1 GW offshore concession projects, totaling four wind farms in east China Jiangsu Province was homemade wind generator announced in October 2010. They will use Sinovel, Goldwind and Shanghai Electric turbines.

China will increase its offshore wind power installed capacity to 5 gigawatts (GW) by 2015 and 30GW by 2020, the National Energy Administration said Wednesday.
The public tender for the second round of offshore wind power concession projects with a total installed capacity of 1.5GW to 2GW will be completed during the first half of 2012, the administration said at a meeting held in the city of Nantong, Jiangsu province.
Liu Qi, deputy director of the administration, said that relevant departments should recognize the importance and urgency of developing offshore wind power.
The country often faces severe power shortages in summers, with wind power generation and transmission systems unable to cope with rising demand.
China faces a 30GW power shortfall this summer, according to data from the China Electricity Council.
Liu said the country should expedite the establishment of an advanced and fully-equipped offshore wind power industry to boost its large-scale development.
In June 2010, Shanghai’s East Sea Bridge’s 100MW offshore wind farm project was completed. It is currently the only offshore wind turbine generator farm that has been put into operation outside of Europe.
