"The article didn’t give a clue as to what generating capability failed, but I can make a pretty good guess: Wind energy."

bad guess...care to try again?
Give me a break. "I... guess"??? come on.

Two coal fired power plants were down because of burst pipes and natural gas fired plants had trouble starting up because of low line pressures. Atmos Energy, which supplies natural gas to the DFW area, is concerned about line pressures if several schools and businesses reopen tomorrow, and they are asking everyone to cut down on their natural gas use.

We Spent Billions on Wind Power… and All I Got Was a Rolling Blackout

The UK gets windmills, while China gets horrible pollution from the rare earth mining needed in order to produce them. More greenie stupidity..

And these wind farms are polluting Scotland's wild lands as well..

In China, the true cost of Britain's clean, green wind power experiment: Pollution on a disastrous scale

By SIMON PARRY in China and ED DOUGLAS in Scotland

Last updated at 10:01 PM on 29th January 2011

This toxic lake poisons Chinese farmers (pictures at link), their children and their land. It is what's left behind after making the magnets for Britain's latest wind turbines... and, as a special Live investigation reveals, is merely one of a multitude of environmental sins committed in the name of our new green Jerusalem.

On the outskirts of one of China’s most polluted cities, an old farmer stares despairingly out across an immense lake of bubbling toxic waste covered in black dust. He remembers it as fields of wheat and corn.

Yan Man Jia Hong is a dedicated Communist. At 74, he still believes in his revolutionary heroes, but he despises the young local officials and entrepreneurs who have let this happen.

‘Chairman Mao was a hero and saved us,’ he says. ‘But these people only care about money. They have destroyed our lives.’

Vast fortunes are being amassed here in Inner Mongolia; the region has more than 90 per cent of the world’s legal reserves of rare earth metals, and specifically neodymium, the element needed to make the magnets in the most striking of green energy producers, wind turbines.

Live has uncovered the distinctly dirty truth about the process used to extract neodymium: it has an appalling environmental impact that raises serious questions over the credibility of so-called green technology.

The reality is that, as Britain flaunts its environmental credentials by speckling its coastlines and unspoiled moors and mountains with thousands of wind turbines, it is contributing to a vast man-made lake of poison in northern China. This is the deadly and sinister side of the massively profitable rare-earths industry that the ‘green’ companies profiting from the demand for wind turbines would prefer you knew nothing about.

Hidden out of sight behind smoke-shrouded factory complexes in the city of Baotou, and patrolled by platoons of security guards, lies a five-mile wide ‘tailing’ lake. It has killed farmland for miles around, made thousands of people ill and put one of China’s key waterways in jeopardy.

This vast, hissing cauldron of chemicals is the dumping ground for seven million tons a year of mined rare earth after it has been doused in acid and chemicals and processed through red-hot furnaces to extract its components.

Rusting pipelines meander for miles from factories processing rare earths in Baotou out to the man-made lake where, mixed with water, the foul-smelling radioactive waste from this industrial process is pumped day after day. No signposts and no paved roads lead here, and as we approach security guards shoo us away and tail us. When we finally break through the cordon and climb sand dunes to reach its brim, an apocalyptic sight greets us: a giant, secret toxic dump, made bigger by every wind turbine we build.

The lake instantly assaults your senses. Stand on the black crust for just seconds and your eyes water and a powerful, acrid stench fills your lungs.

For hours after our visit, my stomach lurched and my head throbbed. We were there for only one hour, but those who live in Mr Yan’s village of Dalahai, and other villages around, breathe in the same poison every day.

Retired farmer Su Bairen, 69, who led us to the lake, says it was initially a novelty – a multi-coloured pond set in farmland as early rare earth factories run by the state-owned Baogang group of companies began work in the Sixties.

‘At first it was just a hole in the ground,’ he says. ‘When it dried in the winter and summer, it turned into a black crust and children would play on it. Then one or two of them fell through and drowned in the sludge below. Since then, children have stayed away.’

As more factories sprang up, the banks grew higher, the lake grew larger and the stench and fumes grew more overwhelming.

‘It turned into a mountain that towered over us,’ says Mr Su. ‘Anything we planted just withered, then our animals started to sicken and die.’

People too began to suffer. Dalahai villagers say their teeth began to fall out, their hair turned white at unusually young ages, and they suffered from severe skin and respiratory diseases. Children were born with soft bones and cancer rates rocketed.

Official studies carried out five years ago in Dalahai village confirmed there were unusually high rates of cancer along with high rates of osteoporosis and skin and respiratory diseases. The lake’s radiation levels are ten times higher than in the surrounding countryside, the studies found.

Since then, maybe because of pressure from the companies operating around the lake, which pump out waste 24 hours a day, the results of ongoing radiation and toxicity tests carried out on the lake have been kept secret and officials have refused to publicly acknowledge health risks to nearby villages.

There are 17 ‘rare earth metals’ – the name doesn’t mean they are necessarily in short supply; it refers to the fact that the metals occur in scattered deposits of minerals, rather than concentrated ores. Rare earth metals usually occur together, and, once mined, have to be separated.

Neodymium is commonly used as part of a Neodymium-Iron-Boron alloy (Nd2Fe14B) which, thanks to its tetragonal crystal structure, is used to make the most powerful magnets in the world. Electric motors and generators rely on the basic principles of electromagnetism, and the stronger the magnets they use, the more efficient they can be. It’s been used in small quantities in common technologies for quite a long time – hi-fi speakers, hard drives and lasers, for example. But only with the rise of alternative energy solutions has neodymium really come to prominence, for use in hybrid cars and wind turbines. A direct-drive permanent-magnet generator for a top capacity wind turbine would use 4,400lb of neodymium-based permanent magnet material.

In the pollution-blighted city of Baotou, most people wear face masks everywhere they go.

‘You have to wear one otherwise the dust gets into your lungs and poisons you,’ our taxi driver tells us, pulling over so we can buy white cloth masks from a roadside hawker.

Posing as buyers, we visit Baotou Xijun Rare Earth Co Ltd. A large billboard in front of the factory shows an idyllic image of fields of sheep grazing in green fields with wind turbines in the background.

In a smartly appointed boardroom, Vice General Manager Cheng Qing tells us proudly that his company is the fourth biggest producer of rare earth metals in China, processing 30,000 tons a year. He leads us down to a complex of primitive workshops where workers with no protective clothing except for cotton gloves and face masks ladle molten rare earth from furnaces with temperatures of 1,000°C.

The result is 1.5kg bricks of neodymium, packed into blue barrels weighing 250kg each. Its price has more than doubled in the past year – it now costs around £80 per kilogram. So a 1.5kg block would be worth £120 – or more than a fortnight’s wages for the workers handling them. The waste from this highly toxic process ends up being pumped into the lake looming over Dalahai.

The state-owned Baogang Group, which operates most of the factories in Baotou, claims it invests tens of millions of pounds a year in environmental protection and processes the waste before it is discharged.

According to Du Youlu of Baogang’s safety and environmental protection department, seven million tons of waste a year was discharged into the lake, which is already 100ft high and growing by three feet each year.

In what appeared an attempt to shift responsibility onto China’s national leaders and their close control of the rare earths industry, he added: ‘The tailing is a national resource and China will ultimately decide what will be done with the lake.’

Jamie Choi, an expert on toxics for Greenpeace China, says villagers living near the lake face horrendous health risks from the carcinogenic and radioactive waste.

‘There’s not one step of the rare earth mining process that is not disastrous for the environment. Ores are being extracted by pumping acid into the ground, and then they are processed using more acid and chemicals.

Finally they are dumped into tailing lakes that are often very poorly constructed and maintained. And throughout this process, large amounts of highly toxic acids, heavy metals and other chemicals are emitted into the air that people breathe, and leak into surface and ground water. Villagers rely on this for irrigation of their crops and for drinking water. Whenever we purchase products that contain rare earth metals, we are unknowingly taking part in massive environmental degradation and the destruction of communities.’

The fact that the wind-turbine industry relies on neodymium, which even in legal factories has a catastrophic environmental impact, is an irony Ms Choi acknowledges.

‘It is a real dilemma for environmentalists who want to see the growth of the industry,’ she says. ‘But we have the responsibility to recognise the environmental destruction that is being caused while making these wind turbines.’

It’s a long way from the grim conditions in Baotou to the raw beauty of the Monadhliath mountains in Scotland. But the environmental damage wind turbines cause will be felt here, too. These hills are the latest battleground in a war being fought all over Britain – and particularly in Scotland – between wind-farm developers and those opposed to them.

Cameron McNeish, a hill walker and TV presenter who lives in the Monadhliath, campaigned for almost a decade against the Dunmaglass wind farm before the Scottish government gave the go-ahead in December. Soon, 33 turbines will be erected on the hills north of the upper Findhorn valley.

McNeish is passionate about this landscape: ‘It’s vast and wild and isolated,’ he says. Huge empty spaces, however, are also perfect for wind turbines and unlike the nearby Cairngorms there are no landscape designations to protect this area. When the Labour government put in place the policy framework and subsidies to boost renewable energy, the Monadhliath became a mouth-watering opportunity.

People have been trying to make real money from Scottish estates like Jack Hayward’s Dunmaglass. Hayward, a Bermuda-based property developer and former chairman of Wolverhampton Wanderers, struck a deal with renewable energy company RES which, campaigners believe, will earn the estate an estimated £9 million over the next 25 years.

Each of the turbines at Dunmaglass will require servicing, which means a network of new and improved roads 20 miles long being built across the hills. They also need 1,500 tons of concrete foundations to keep them upright in a strong wind, which will scar the area.

Dunmaglass is just one among scores of wind farms in Scotland with planning permission. Scores more are still in the planning system. There are currently 3,153 turbines in the UK overall, with a maximum capacity of 5,203 megawatts...

"I can make a pretty good guess: Wind energy"

Off by 540 degrees. This couldn't have worked out better if da Rat had written the script his elf. Not only was it caused by coal going down, but wind helped keep your sorry ass warm. I can make a good guess he won't tell you this. Fortunately, you have me to show you the shit on your face. Ain't I cool?

Wind Energy Helps Save Day as Fossil Fuel Plants Falter
february 07, 2011
Across the Great Plains this week, wind power played a major role in helping keep the lights on as the region dealt with a record winter storm.

Over the last few days we've learned more about the events that led to the rolling blackouts that occurred Wednesday morning in Texas. Wind turbines played a critical role in limiting the severity of the blackouts, providing enough electricity to keep the power on for about three million typical households.

ERCOT, the Texas grid operator, has confirmed that wind farm was providing between 3,500 and 4,000 MW of electricity (about 7% of ERCOT demand at that time), roughly what it was forecast and scheduled to provide, during the critical 5-7 AM window on Wednesday when the grid needed power the most.

In an interview with the Texas Tribune, ERCOT CEO Trip Doggett put it this way: "I'm not aware of any nuclear plant problems, and I'm not aware of any specific issues with wind turbines having to shut down due to icing. I would highlight that we put out a special word of thanks to the wind power community because they did contribute significantly through this timeframe. Wind was blowing, and we had often 3,500 megawatts of wind farm generation during that morning peak, which certainly helped us in this situation."

We've also learned what did cause the rolling blackouts: a large number of fossil-fired power plants broke down and failed to provide the amount of electricity they were scheduled to provide. The grid operator and others have confirmed that 50 power plants totaling 7,000 MW of power capacity experienced outages and went offline due to the cold weather.

At least two of these were large coal power plants that went offline due to pipes freezing or breaking at the plants. Some gas-fired plants also experienced outages due to the cold, and some gas-fired plants were unable to produce as scheduled due to inadequate pressure in natural gas pipelines due to high demand.

In addition, an estimated 12,000 MW of coal and gas-fired power plants were offline and undergoing maintenance during this time period, making them unavailable to provide electricity. While there are scattered reports that a few of Texas's roughly 7,000 wind turbines experienced reduced output due to the weather, the vast majority of the fleet was unaffected and continued producing electricity on schedule.

Mack Grady, an electrical engineering professor at UT Austin, has also released data collected from monitoring points on the Texas grid showing large amounts of wind energy flowing out of West Texas to help stabilize the Texas grid as fossil-fired power plants elsewhere in the state failed and went offline.

Elsewhere across the Great Plains, wind energy also helped keep the lights on as the region dealt with increased electricity demand and other disruptions caused by the storm. Data from the Midwest Independent System Operator (MISO), which provides power to parts of 13 states in the upper Midwest, show that wind energy was providing a large amount of electricity through the height of the storm.

From noon Wednesday to noon Thursday, wind was producing an average of 5,350 MW, roughly 7% of the region's power needs. From noon Thursday to noon today, wind averaged 6,175 MW of output, about 8.25% of the region's demand.
