"The decision has to be taken quite carefully as it is a big investment. We need to make sure the costs are fully understood," he said at the World Energy Congress in South Korea last week. Lancaster said more solid wind data would be required to confirm the project's economic feasibility, and that a couple more years of study were needed.
Ng says the wind farms are unsightly and kill birds, and are an unreliable source of energy. He makes the point that the Shanwei wind farm operates at an average of 17 per cent to 18 per cent efficiency: "The government is silly to support this project - building this white elephant just for the sake of appearing to do something green, when in fact it is damaging the environment, and costing the community a lot of money in terms of higher fuel bills and higher costs to business. The only beneficiaries are the power companies."
Typhoon Usagi also broke off blades of another nine wind turbines when it hit the Honghaiwan Wind Farm in coastal Shanwei City, Guangdong.
Japan's commitment to restarting many of its 50 idled reactors appears stronger than ever, a year after a previous government said it would begin to phase out nuclear power completely. Prime Minister Shinzo Abe, who took office in December, says nuclear power remains essential, even with a surge in generation capacity from solar, wind and other renewable sources, and that the world's No. 3 economy cannot afford the mounting costs from importing gas and oil.
"We have built the minimum necessary facilities, including power transmission lines according to demand, and there are times when connecting (renewable energy sources) is difficult due to capacity issues," an official with Hokkaido Electric said. ...in the absence of grid access rules, utilities often do not reveal how limited their delivery lines actually are or the details of the construction costs for letting providers use their grids.
Laying large-scale photovoltaic panels for power generation requires wide areas of flat, vacant land, ruling out urban areas. Land suited for wind farms, meanwhile, is often in the less populated Tohoku and Hokkaido regions in the north. While these areas have power delivery lines, their capacity is often limited due to low regional demand for electricity.
A weaker currency inflates overseas debt when repaid with local earnings, increasing finance costs, while also boosting prices of imported components and other raw materials. The average yield for dollar debt of Indian companies jumped as much as 2.56 percentage points to a 19-month high of 6.32 percent on Aug. 22.
What was considered as petty thefts earlier have now taken the shape of an organized operation. About 15% of the turbines put up by developers like Suzlon Energy, Inox Wind, Gammesa, and Enercon (India) are under complete breakdown due to theft, a source in the industry body Indian Wind Power Association (IWPA) said.
Five workers died and another five were injured when a wall collapsed at the approach to a wind farm currently under construction in south China's Guangxi Zhuang Autonomous Region. ...Five died despite medical efforts, and the other injured were receiving treatment at two different hospitals.
Vestas has filed lawsuits against the two Indian companies embroiled in the Danish company's row with former CFO Henrik Nørremark. Vestas has filed the lawsuits in New Delhi's high court against RRB Energy and ECO RRB for the return of money handed over by Norremark, in deals that were not sanctioned by the Danish company's board.
European and Chinese wind turbine makers are poised to do battle away from their domestic markets as the focus in the 60 billion euro ($85.6 billion) industry shifts to North America, Brazil and India. Hit by overcapacity and plunging prices in Europe and China's saturated markets, manufacturers of wind turbines are under pressure to find new areas of growth to boost single-digit profit margins.
The Wind Independent Power Producers Association has filed a petition with the Delhi High Court against the power regulator, the Central Electricity Regulatory Commission' over the Commission's recent ‘scheduling and forecasting' order.
Hardly three weeks after it was installed with much fanfare, one of the leaves of the windmill at the Marine Drive came off a second time in heavy rain and wind on Thursday afternoon leaving the Greater Cochin Development Authority (GCDA) with egg on its face. ...the company had undertaken the project on a trial basis and would replace it with solar power if the windmill was found unsuccessful.
A directive took effect this week ordering wind farms with a capacity of 10 megawatts or more to forecast their generation in 15-minute blocks for the following day. Missing estimates by more than 30 percent will incur penalties. ...The infrastructure can't cope with intermittent wind- and sun-power generation, which has doubled in capacity in five years to almost 20 gigawatts.
The reinstalled windmill has only three fan leaves, compared to the original five, and the shaft thickness has been increased from two to five inches, said sources. "As we have high winds at Marine Drive, especially in the morning, we have reduced the number of wings in the windmill.
The broken blade came from the No. 12 turbine. It landed on a beach more than 30m away from the wind farm. The turbine has not been in operation since the blade broke, but the break triggered concerns about the quality of the turbines. The broken part was still on the beach as of Saturday.
GCDA chairman N Venugopal said that the bolts of the windmill blades were not tightened properly and the company which installed it was scheduled to carryout repair works on Saturday to fix it properly.
Maharashtra lost the second largest chunk of forest land to wind power projects, reveals a report released by the Delhi-based Centre for Science and Environment (CSE) on Wednesday. ..."We recommend strict green norms for wind power projects." Bhushan said linear fragmentation -- the building of roads and transmission lines -- has the biggest impact on forests, wildlife and water bodies.
With 80 per cent of the country's electricity coming from fossil fuels and nuclear energy, renewable sources of energy such as wind-power are becoming essential. However, it seems that this apparently ‘clean' energy has a few dirty secrets as far as the environment is concerned.
Sinovel Wind Group Co. has confirmed that it is closing four international subsidiaries, marking the latest setback for the company, which is one of China's largest wind-turbine manufacturers. In a filing to the Shanghai Stock Exchange on Monday, Sinovel said it would shut its units in the U.S., Belgium, Italy and Canada. It is unclear how large these units are.
