15 十 11 Onshore wind turbines manufacturers projects in Brazil and China
Asset financing of utility-scale renewable energy projects was 27 percent lower in the third quarter last year at $33 billion.
The increase in financing was mainly driven by offshore wind investment. Three large offshore wind farms in the North Sea totaled more than 1 gigawatt in capacity and $6.3 billion in investment.
There were also large financings for photovoltaic (PV), solar thermal and biofuel projects in the United States, a geothermal plant in Indonesia and onshore wind turbines manufacturers projects in Brazil and China, the report said.
“Over the past three years we have seen extraordinary falls in the prices of clean energy equipment — wind turbines and solar photovoltaic panels. As these figures show, this has driven up installation rates and asset investment levels,” Michael Liebreich, chief executive of Bloomberg New Energy Finance, said in a statement.
“However, there is still not enough demand to soak up significant over-supply, so prices and margins have remained under pressure and manufacturers’ share prices are being crushed,” he added.
The average price of PV modules has fallen by a third since autumn 2010 and by 70 percent since mid-2008, while wind turbine prices have fallen by 20 percent since 2009, the report showed.
This has made renewable energy technologies more cost-competitive with fossil fuel power sources but have been painful for supply chains.
However, renewable energy stocks have lagged fossil fuel energy and wider global stocks over the past few months and the year to date, underperforming as world shares slid on concerns about slow global economic growth.
Wind power generator shares have fallen sharply as the risk of f

05 八 11 Sinovel took full advantage of the boom in the Chinese market
Vestas is still the world’s top wind turbine generator manufacturer in terms of its percentage of market volume, but GE Energy lost its title as the second largest supplier to China’s Sinovel. Together Vestas and Sinovel delivered 10,228 MW of capacity in 2010. The two leading suppliers’ share of the total deliveries to the market was 25.9 percent in the year, which is a one percent increase compared with that of 2009 from the two players.
Sinovel took full advantage of the boom in the Chinese market, enabling it to move up from the third position in 2009 to second in 2010. Conversely, GE Energy dropped to third place due to the economic downturns in the US market. And, GE Energy is closely followed by another Chinese supplier, Goldwind, which installed almost the same number of turbines as GE in 2010. German Enercon ranks at No. 5 in the world, and is followed by Indian-based Suzlon Group at No. 6.
In their home wind power generator market Chinese domestic turbine manufacturers made further gains, while foreign-owned manufacturers only achieved a 10.5 percent market share in 2010 – a 3.5 percent drop from the previous year. Along with Sinovel and Goldwind, two other Chinese wind turbines manufacturers were listed in this year’s top 10 in terms of global capacity delivered. Dongfang, the third largest Chinese manufacturer, first entered the top 10 list in 2009, and United Power entered for the first time in 2010. Meanwhile, other Chinese companies Mingyang, Sewind and Hara XEMC, listed as No. 11, No. 14 and No. 15 in the world respectively, are emerging to challenge the positions of the traditional market leaders from Europe and the US.
It is worth noting that 2010 also saw more MW-rated Chinese manufactured turbines exported. During the year, five Chinese turbine suppliers installed 13 machines in five different foreign markets. Following its first three 1.5-MW direct drive wind turbines installed in the US in 2009, Goldwind installed six units of its 750-kW-rated gear drive turbines in Cuba. Meanwhile, Mingyang and A-Power installed their first wind turbines in the US market in 2010 and HEAG also installed three 1.5-MW turbines in Chile and White Russia.

01 八 11 Wind turbines are getting really big
Wind turbines are getting really big — some with blades as long as a football field — and more powerful, often generating 50 times more electricity than the first generation of wind-power machines built in the 1980s.
But scientists are also studying how to harness the wind in different ways that could help allay concerns that today’s turbines are unattractive, noisy and sometimes even dangerous.
Already in the works: Turbines that float and small wind turbines that fly. Turbines without blades and turbines with blades fat enough to fit a double-decker bus inside.
They won’t just be on hillsides either. Some will be in the ocean, while others will be on rooftops and light poles. A few will even be in the sky.
One design was inspired by the humble bumblebee.
Sabri Sansoy, a graduate of the Massachusetts Institute of Technology and former rocket engineer, has built a 19-foot-tall prototype whose blades, rather than spin in a circle, move in a figure-eight motion like the insect’s wings. Sansoy hopes the design will generate more electricity than turbines of similar size.
“I’ve been called everything from brilliant to a nincompoop over this,” said Sansoy, whose Marina del Rey, Calif., company, Green Wavelength, is looking to commercialize the technology.
But “there’s a lot of people interested in this kind of thing, taking energy out of the wind,” he said.
That’s because there’s a lot of money being poured into finding ways to ease off coal-based electricity. Last year, the Department of Energy set aside a record $79 million for its wind generators -program budget — nearly $20 million more than its previous top allotment in 1980.

08 七 11 Chinese wind blows strong in Ireland
A week of industrial-scale initiatives in wind and solar had as its highlight Chinese wind turbine manufacturer Sinovel’s capture of a deal to supply 1GW of turbines to Ireland. The transaction will be by far the largest coup for a Chinese wind turbine maker in Europe so far, and will create some anxiety in countries such as Germany, Spain and Denmark that have established turbine assembly industries.
Sinovel will supply the machines for €1.5 billion ($US2.2 billion) worth of wind farms under development over the next five years by Irish company Mainstream Renewable Power.
Mainstream, headed by Eddie O’Connor, the entrepreneur behind Airtricity, one of the most active wind farm developers of the last decade, says it will get debt finance for the new projects from China Development Bank, the state-owned lender.
The deal between Mainstream and Sinovel for small wind turbines will shine a spotlight on the dilemma facing political leaders in Europe and North America over the supply of renewable energy technology. China produces many of the cheapest wind turbines and solar panels in the world, providing the opportunity for countries to install low-cost renewable power. On the other hand, importing Chinese hardware will not create the “green jobs” that politicians crave.
Sinovel is attempting to assuage this concern by raising the prospect of inward investment in Ireland, or nearby. Lecheng Li, the company’s senior vice president, said: “As we gain certainty on project execution schedules, we will review our plans for localising operation and maintenance activities as well as possible component manufacturing.”
Ireland is not the first European country to see the prospect of the installation of Chinese-made turbines. In April, Sinovel agreed to team up with Athens-based Public Power Corporation to develop wind farms in Greece.
And the US has been the scene of a number of deals involving Chinese home turbine turbines makers in the last two years. Mainstream is developing a 106.5-megawatt project in Illinois with China’s Xinjiang Goldwind Science & Technology, and Goldwind also has projects in Minnesota, Ohio and Rhode Island.
