In a blow to a region hit hard by the Fukushima nuclear disaster, offshore floating wind turbines being operated on a trial basis here are producing much less electricity than initially anticipated. The disappointing output so far is casting a shadow over the government-backed project.
Chinese wind turbine maker Sinovel Wind Group Co was convicted on Wednesday of U.S. charges that it stole trade secrets from AMSC, causing the Massachusetts-based company to lose more than $800 million. A federal jury in Madison, Wisconsin, found Sinovel, once AMSC’s largest customer, guilty on all charges it faced, including conspiracy, trade-secret theft and wire fraud, the U.S. Justice Department said.
The committee heard testimony last week that the rotating blades of the nine 540 ft. tall turbines could decimate the red falcon population in the area.
Much of the country’s renewable energy supply is currently subject to double-digit rates of curtailment. This curtailment has been going on for quite some time, leaving many of China’s clean power systems seeing little use. It has also highlighted longstanding problems with the country’s aging energy infrastructure.
Around 0.09 per cent of ALRO land – or about 3,695 rai (591 hectares) of a total 41 million rai – has already been used for these undertakings as per NCPO order 31/2560. The order has been criticised by land activists, academics and farmers who see it as an attempt to seize land preserved for landless farmers in order to top up the wealth of energy and mining conglomerates.
Three companies want more than 70 turbines to go up, but the ministry says residents’ ears, the landscape, birds and bats would suffer as a result; The ministry’s opinion relies on a paper by the companies themselves. The ministry says 13 of the turbines would be less than 500 meters from homes, which conflicts with the recommendations of both the environmental protection and health ministries because of the noise.
Deserts, often considered wastelands, are crucibles of spectacular wildlife, but they are threatened by India’s ambitious renewable energy generation target of 175 GW by 2022. The ecological footprint of an individual wind turbine or solar panel might be negligible, but massive wind or solar farms require huge swathes of land. Roads are constructed to lug turbines, and earthmovers rip through forests or grasslands, permanently altering the landscape.
A wind turbine at the Kushizaki power plant in Karatsu, Saga Prefecture, is on fire with black smoke pouring out on the afternoon of Aug. 21.
Under the old subsidy system, all projects qualified to receive a fixed rate for their power. The new one is designed to give the government more control of the capacity built and the cost of each new contract. ...According to the ratings agency India Ratings and Research, there could be a substantial dip in wind capacity additions in the current financial year ending March 31.
The government’s plans to set up wind turbines to generate electricity in the Galilee were supposed to herald a new environmental era. But residents are campaigning against the enterprise, out of fear of damage to the landscape, noise and other hazards.
“Every day, 15-20% of wind power is being curtailed,” said an official of the Wind Independent Power Producers Association (WIPPA). “On some days, power has even been switched off completely by the discoms’ state load distribution centres (SLDCs).”
The Agricultural Land Reform Office (Alro) said Wednesday that 16 wind farm projects located on Sor Por Kor government land are legal and can continue as planned.
On Jan 31, the Nakhon Ratchasima Administrative Court ruled the Chaiyaphum land reform committee's decision to lease the land to Thep Sathit Wind Farm Co was unlawful and ordered it revoked. According to the court, the land lease for the company breached the agricultural land reform law which requires that use of Sor Por Kor land for activities other than agriculture can be done only if the activities are in the interests of farmers.

INDIA - This video shows a wind turbine that caught fire and self-destructed. In the background, a second turbine is also on fire. The root cause of the failure has not been disclosed..
Yet even with double the wind capacity, China still produces less electricity from turbines when compared with the U.S. That’s because it’s installing lower-quality machines using less reliable breezes and doing so more quickly than the distribution grid can take in the flows.
Renowned biodiversity expert Dr. Rohan Pethiyagoda has questioned a poorly researched Initial Environment Examination Report (IEER) saying it poses a threat to the Vankalai Sanctuary near Mannar. ...He also says that the IEER provides almost no evidence that the unique natural heritage offered by the Vankalai Sanctuary will be preserved as a result of the project, especially with regard to bird life with the proposed transmission line. “This is a matter of urgent national importance and there needs to be a public debate on this plan."
Grid connectivity is not streamlined, so problems arise due to inconsistent supply from the windmills. Local industries blame them for disruptions in power supply, eventually resulting in damage to expensive equipment. While one can argue in favor of the little electricity these windmills produce, it remains to be seen how much loss has been incurred from their use of farm land, installation, and connectivity costs—and, of course, the costs of frequent disruptions from rain.
KEPCO initially projected that its investment in the wind power plants would generate a stable return of 6 percent to 7 percent per annum as the power plants had a 20-year long contract with the local electricity firms. However, the pre-feasibility study done by Korea Development Institute (KDI) on the request from the Korea’s Ministry of Strategy and Finance found that the investment would yield a mere 2 percent annual return.
German electronics giant has agreed to pay the Israeli government a NIS 160 million penalty for bribing senior Israel Electric Corporation (IEC) (TASE: ELEC.B22) executives to rig a tender for turbines more than ten years ago. Siemens will also appoint an external inspector for supervision over their activities in Israel.
