Title: Huge wind turbines – taller than the Statue of Liberty -- are toppling over in a ‘rash’ of incidents

Bloomberg Business Week, no foe of green energy, headlines: Wind Turbines Taller Than the Statue of Liberty Are Falling Over.” The article beneath the headline reports on a variety of alarming disasters involving wind turbines, including collapses of very tall sructures.

On a calm, sunny day last June, Mike Willey was feeding his cattle when he got a call from the local sheriff’s dispatcher. A motorist had reported that one of the huge turbines at a nearby wind farm had collapsed in dramatic fashion. Willey, chief of the volunteer fire department in Ames, 90 miles northwest of Oklahoma City, set out to survey the scene.

The steel tower, which once stood hundreds of feet tall, was buckled in half, and the turbine blades, whose rotation took the machine higher than the Statue of Liberty, were splayed across the wheat field below. The turbine, made by General Electric Co., had been in operation less than a year. “It fell pretty much right on top of itself,” Willey says.

Another GE turbine of the same model collapsed in Colorado a few days later. That wind farm’s owner-operator, NextEra Energy Inc., later attributed it to a blade flaw and said it and GE had taken steps to prevent future mishaps. A spokesperson for GE declined to say what went wrong in both cases in a statement to Bloomberg.

The instances are part of a rash of recent wind turbine malfunctions across the US and Europe, ranging from failures of key components to full collapses.

The article blames the “rash” of incidents on the rush to install turbine capacity, but there are also permanent factors that make engineering, building, and maintaining wind farms difficult and risky. To develop meaningful amounts of power, the blades on the turbine have to be big, and when big blades spin in heavy winds, the tips can end up hitting supersonic speeds, putting great stress of the materials used to construct them. Big blades also requite tall towers, which are then subject to stresses as winds blow and can gust during storms to velocities that test the strength of the materials and the design of the towers.

And, of course, tall, string towers require a lot of construction materials that have (ahem) a considerable carbon footprint to create. Compared to the amount of “carbon free” electricity generated, the carbon emitted in manufacturing and construction of the towers may take many years to counterbalance. Consider that the relatively low electricity production of each tower (compared to a coal or nuclear fired plant) means that far more power transmission lines must be constructed, and there is a carbon footprint involved, not to mention the excess demand created for copper, which has its own environmental issues in mining and refining, and the problems with meeting demand when creating new copper mines hits a high wall of resistance from the very same environmentalists who think windmills are a solution to the problems they imagine CO2 creates.

But with wind farms, longevity is an issue. The unpredictable nature of winds, with the speed and direction changing abruptly, means that complex transmission boxes must be attached to each turbine, and these transmission boxes are stressed when high winds occur and suddenly change direction. They need maintenance crews at the ready. In my consulting days, I encountered a wind farm project whose transmission boxes regularly exploded when sudden gusts of wind over-stressed them, creating their own mini environmental disasters from the transmission fluids spewed onto the ground.

All of these problems are in addition to the fundamental problem with wind energy: it is unreliable. When the wind doesn’t blow, you get no electricity, so you still need backup generating power at the ready, and that usually involves carbon based fuels, since constructing nuclear plants is so rare these days.

Then there are all the millions of birds, including the federally protected bald eagles, that are killed each year by windmills.

Wind farms, in other words, are one of the worst options for providing electricity.

This Photo Of Two Engineers Hugging Atop A Burning Turbine Before They Died Is Heart-Breaking!

This photograph tugs at your heartstrings. Two engineers hug and cling to each other as fire and smoke creep toward them. They both died after. According to news reports, one of them jumped off the turbine while the other succumbed to the fire. What makes this more heartbreaking is that the two engineers are just aged 19 and 21.

This accident happened in October of last year at a wind farm in Ooltgensplaat, Holland. A crew of four were conducting routine maintenance at the 67-meter high wind turbine when fire suddenly broke out. Two of the four people were able to escape while the other two got trapped.

“The most terrifying force of death comes from the hands of Men who wanted to be left Alone.
TRUE TERROR will arrive at these people’s door, and they will cry, scream, and beg for mercy…
but it will fall upon the deaf ears of the Men who just wanted to be left alone.”
