The grand U.S. ambitions of Indian wind-turbine manufacturer Suzlon Energy Ltd. are facing mounting problems. The Indian company -- the world's fifth-largest wind-turbine maker by sales -- earlier this year acknowledged that 65 giant blades on turbines it had sold in the U.S. Midwest were cracking because of the extreme gusts in the region. The company is reinforcing 1,251 blades, almost the total it has sold in the U.S. Now, other problems are emerging, in part because the company quickly ramped up U.S. sales to meet burgeoning demand for alternative energy. ...

In a filing with the U.S. Securities and Exchange Commission in February, Edison Mission Energy, a unit of Edison International, said the 144-foot-long windmill blades it recently bought from Suzlon have begun to split at three wind-power sites it operates in the Midwest. Suzlon has recalled 1,251 blades from its top-of-the-line turbines, which represent the majority of blades the company has sold to date in the U.S.. Its troubles don't end there. A year ago, the company bought a controlling stake in a large German turbine manufacturer, REpower Systems AG, in one of India's biggest overseas acquisitions. ...Now, Suzlon can't get its hands on the blueprints. Hamstrung by a German corporate law, Suzlon must offer to buy out minority shareholders before it can demand REpower's designs. It's unlikely that the company could make a tender offer until 2009, say people with knowledge of the companies. ...Mr. Kher blamed the cracks on the Midwest's unexpectedly violent changes in wind direction. Though Mr. Tanti says that only 45 blades have cracked, Suzlon says it will add an extra lamination layer to almost all of the blades it has shipped to the U.S. To repair cracked blades and reinforce the rest, the company expects to spend $30 million.

Wind turbine makers face a ``major challenge'' getting equipment due to surging demand and probably won't be able to cut delivery times for three years, said Suzlon Energy Ltd., India's biggest wind farm construction company. Lead times to supply wind turbines, which have reached at least 15 months, will take time to reduce as suppliers clear order backlogs and add an ``unprecedented'' amount of new capacity, Andre Horbach, Amsterdam-based chief executive officer at Suzlon, said today in Melbourne. Suzlon has a $3.5 billion order backlog, he said.

Solar batteries, wind farms and tidal power plants can be effective only in small part of Russian territories, besides, energy storage and servicing of such devices are quite costly. Professionals predict share of alternative energy sources in Russia won't exceed 1.5-2% during next 30-50 years.

Power-generating wind turbines will soon have to comply with tough new technical standards to ensure they can withstand typhoons, lightning strikes and other extreme weather conditions. Wind-power generation is a major pillar in the government's push to use alternative energy sources to fight global warming. In recent years, however, storms have caused extensive damage to many wind turbines. International standards drawn up in Europe are not sufficient to protect wind turbines from Japan's weather patterns, according to officials of the Nuclear and Industrial Safety Agency, an arm of the Ministry of Economy, Trade and Industry.

TOKYO: Mitsubishi Heavy Industries Ltd. said Wednesday it has received orders for a total of 788 wind turbine power generation systems from five U.S. companies. The order included 166 wind turbines for Edison Mission Energy, 118 for Babcock & Brown Ltd., 197 for Airtricity Inc. and 180 for Eurus Energy America Corp. Another unnamed company ordered 127 units, the Japanese company said.

Wind turbines that can operate through cyclones and earthquakes are increasingly being installed on small, isolated islands that seek improved energy independence, a wind power producer said on Friday. France's fifth largest wind power producer Aerowatt this week launched a 3.85 megawatt-wind farm on the small cyclone-prone French Reunion Island in the Indian Ocean, enough to provide power to 12,000 inhabitants out of a total of 700,000. "This is the first wind farm installed on Reunion," Jerome Billerey, head of the company, told Reuters. But installing wind turbines on remote islands can often be complex due to poor logistics, limited port infrastructure and the hurdle of regular cyclones.

OSLO, Sept 20 (Reuters) - Wind power could generate almost 30 percent of the world's electricity by 2030 and is growing faster than any other clean energy source, a wind business group and environmental lobby Greenpeace said on Wednesday.

Canadian manufacturer of solar cells and modules Photowatt (PHWT) filed to go public last week; its prospectus contains an overview of the renewable energy industry, and trends in solar energy. The excerpt below is from the company's F-1 filing:

TSUKUBA, Ibaraki -- The Tsukuba municipal government has decided to pull the plug on a wind generation project after spending hundreds of millions of yen on wind turbines designed by Waseda University that turned out to be a flop.

The project to make Tsukuba a self-sufficient showpiece for green energy has failed, heaping scorn upon the central government programme to test alternative sources. It is likely to be used as ammunition by sceptics elsewhere, including Britain, where the Government this week published its energy review. Tsukuba is now locked into a spiral of civil litigation, criminal investigations and an unprecedented attack on the academic reputation of Waseda University, Japan’s most respected seat of learning.

Chinese developers unveiled the world’s first full-permanent magnetic levitation (Maglev) wind power generator at the Wind Power Asia Exhibition 2006 held June 28 in Beijing, according to Xinhua News..

A breeze of just over 5 kms an hour is sufficient to start the machine, which means it can operate for many more hours than traditional wind turbines, said Zeng Zhiyong, president of the Zhongke Hengyuan Energy Technology which developed the turbine with the help of the Chinese Academy of Sciences in Guangzhou.

Most experts also believe that, using current technologies, there isn't enough land to make a serious dent in oil consumption. Some scientists say production will consume more conventional energy than it will save, and environmentalists came out this month against plans by Indonesia to convert millions of acres of rain forest on the island of Borneo into palm oil plantations.

"When you gasify coal and burn the resulting gas, you can easily remove the hazardous materials from it, such as mercury. We have already developed the gasification technology needed for the power generation. What we need to do is to pull down the cost and find good business partners in Korea, Japan and China."

Niskayuna, New York [RenewableEnergyAccess.com] From the country with still not one wind turbine installed offshore comes news of a partnership between GE Energy and the U.S. Department of Energy (DOE) on a research and development contract to build a new fleet of next generation offshore wind turbines. And with the turbines expected in the 5-7 MW range, these could be the largest turbines ever built.

The U.S. Environmental Protection Agency's Wind Technology Partnership rolled out a new tool to aid energy planners and wind developers in China's Hebei province.
