29 一 12 failures and malfunctions of wind turbines
However, there is a dark side to this story of rapid success. China has witnessed, by far, the highest number of accidents caused by failures and malfunctions of wind turbines, including massive power outages and even some fatalities. With its domestic market saturated and clear signs of overcapacity and upcoming consolidation, some of the biggest Chinese producers have announced plans for international expansion, she explains.
While there is no doubt of the Chinese wind generators manufacturers’ ability to learn quickly, adapt and alter the technology to bring the costs down, F&S believes that the wind power market presents a tougher challenge for the Chinese to crack.
“Firstly, there are a number of technology- related quality issues that the Chinese manu- facturers will have to sort out before they are able to deliver a technology solution on a par with the established Western manufacturers. The technology gap is expanding, with US industrial group GE, residential wind generator company Vestas, diversified technology group Siemens and other companies investing in improvements that increase their turbines’ availability and reliability.
“A technical fault leading to reduced availability presents a huge risk to a developer and can wipe out a large chunk of expected profits. A faultless operating record will have a posi- tive impact on project developers, who will be more confident in the quality of the Chinese turbines. But we need to [take into consideration] that it will take years to build this trust. We are witnessing Chinese wind turbine manufacturers taking the first steps in the right direction, although the government had to step in and set stricter regulations”, adds Bakhareva.
The State Electricity Regulatory Commission has released stricter technical regulations, especially for low-voltage ride-through (LVRT) reformation. Additionally, 18 industry standards were released in November last year by the National Bureau of Energy.

24 一 12 US investigation into exports of wind turbines towers
he Chinese government has hit back against a US investigation into exports of wind turbines towers, warning that the escalating trade spat runs counter to global efforts to curb carbon emissions and could damage clean-energy co-operation between the two countries.
The US Commerce Department announced last week that it will respond to a complaint by a group of American wind turbine tower manufacturers over low-cost towers imported from China and Vietnam by launching a formal probe into whether the imports breach trade rules.
However, China’s Ministry of Commerce responded immediately, issuing a statement on its website in which it criticised the investigation and offered a thinly veiled threat that China could take retaliatory action if the US government imposes import tariffs.
“This investigation will not only be harmful to the development of Sino-US new-energy cooperation; it will harm the interests of the US industry, and is not in line with global efforts on climate change and energy security,” it said.
The ministry also urged the US to stand by commitments made at the G20 to avoid introducing new protectionist measures.
However, some critics maintain that the generous subsidies and preferential treatment the Chinese government offers many of its clean-tech firms amount to unfair competition.
China’s reaction to the new probe almost precisely mirrors its initial reaction to news wind generator last year that the US would investigate whether imports of solar technologies are in line with World Trade Organisation rules.
Chinese officials escalated the row last November by announcing they would launch their own investigation into the level of subsidy the US government has provided its domestic clean-energy firms.
“The Ministry of Commerce has decided to initiate a trade barrier investigation into policy support and subsidies for the US renewable energy sector,” it said in a statement, adding that US policies “constitute a trade barrier against the export of Chinese renewable energy products to the United States” and “ small wind turbines violated the United States’ commitments under World Trade Organisation rules, and are an unreasonable barrier and restriction on China’s renewable energy industry, reducing the competitiveness of Chinese products in the US market”.

08 十二 11 China’s cumulative carbon emissions
The chief economist of the International Energy Agency said China will be the leader in small wind turbines clean-tech products by 2030 but it simply won’t be enough to cut down on its carbon emissions.
“China will be the champion of wind turbine smanufacturers wind and solar products as well as electric vehicles in 20 years,” said the IEA’s Fatih Birol. “China is making great efforts in clean energy and experimental carbon caps in many provinces, a move we do not see in many places in the world.”
China recently laid out a plan to control greenhouse gas emissions in the coming five years with a goal of cutting 17 percent for each unit of GDP by 2015 from 2010 levels. The 17-percent goal has been localized to provincial governments and to certain industries.
But despite China’s efforts to cut greenhouse gases, the country’s energy demand will continue to grow at an incredible pace. China and India are expected to contribute 50 percent of growth to emerging markets, whose energy demand is expected to spike, Birol said.
China’s cumulative carbon emissions will overtake the European Union in 2035 as the world’s second-largest emitter after the United States, according to the IEA’s estimates. Cumulative CO2 emissions are the total CO2 emissions of a country, region or group during a specific time span. The US, EU and China are the world’s top emitters.
China has been making strides in improving its clean energy industries; renewable energy is one of China’s seven strategic industries. The country is aiming for home wind generator industries in clean energy to push for 15-percent market share of energy industries in the nation by 2020.
China’s wind turbine generator manufacturers — Sinovel and Xinjiang Goldwind — ranked among the world’s four largest by market share in 2010, according to the BTM consulting. Sinovel and Xinjiang Goldwind may overtake Denmark’s Vestas Wind Systems A/S, the world’s biggest supplier, by 2015, according to a Bloomberg New Energy Finance report.

26 十一 11 U.S. researchers have developed high-altitude wind turbines
U.S. researchers have developed high-altitude wind turbines called “Alto Rose” (Altaeros). The generator looks like a turbine engine aircraft under the wing, but the former is to produce energy, which consumes energy. Since there is no power, then the “Alto Rose” How can floating in the air it? It turned out that a pneumatic generator. Generator is cylindrical outer bag, which is full of helium is much lighter than air, so that it can be suspended in the air. Thus, this generator is also known as balloon generator. Some people worry that the wind turbine generator will affect aviation safety air bag, in fact, it just is not particularly close to the airport from the aircraft would not be affected because of its suspension height can be 50 to be adjusted within the range of 3,000 meters, near the airport can be installed too low a number.
Airbag power generator wind turbine components and the ground is no different, mainly with a few blades of a turbine. When the high-altitude wind is blowing, when pushing the turbine rotation, electric power is produced. Have a slender wire connected with the generator, power transmission along the wire to the ground. Rod fixed to the ground with wind turbines, this kind of high-altitude small wind turbine design that can move at any time. Generator is very convenient retractable airbags, a person can easily retractable. If you do not need such a place wind turbines, the pulling of a wire, as close as kites can easily pull the generator on the ground. Then, let go of the helium balloon, the balloon folded, the generator can easily be transported to other needed areas.
