No, they aren't, of course. That would be absurd -- an environmental group promoting the industrial development of wild places. Oh, wait, but they do. Just call it green and urgently necessary, and formerly inaccessible ridgelines and prairies are yours to exploit.
While I completely share Greenpeace's concerns and the goals of their "Clean Energy Now" campaign, they say that wind could supply 10% of the world's electricity by 2025. To supply 10% the world's use in 2001 (13,934 TW-h) would have required an average output of 159,064 MW, representing an installed wind capacity of 636,256 (25% capacity factor) to 795,320 (20% c.f.) MW, or 424,171-530,213 1.5-MW turbines. Greenpeace urges aggressive use of off-shore sites, which can use larger-capacity turbines and might initially show better capacity factors, but the number required is still outrageous. In 2025, projected electricity demand will require 1.75 times more than the numbers just calculated: 750,000-1,000,000 turbine towers to provide just 10% of our electricity.
Besides being so much and doing so little, it does nothing at all about other energy use besides that for generating electricity. Ten percent reduction in all energy use could more easily, more cheaply, and -- most significantly for environmentalists -- without adding more industry to our already so diminished landscapes be achieved by implementing simple conservation and efficiency measures.

Spring!
There's still 3 feet of snow on the ground, but the road's a treacherous mudslick and sugaring is expected to begin at any day now. Most dramatically on this feast of St Patrick was when we went outside this morning for taking the wee one to what they euphemistically call a school and the sun was already above the ridge and shining down on us.
Speaking of electricity use in Massachusetts
As noted in the previous post, there has been some confusion about electricity demand in Massachusetts (actually, at issue was the whole New England grid, but also at issue are wind turbines proposed in the Berkshires of Massachusetts). According to the U.S. Energy Information Agency, 52,410 GW-h of electricity were sold in Massachusetts in 2002. The annual output of a 1.5-MW wind turbine can be expected to be (granting a generous 25% capacity factor) not quite 3.3 GW-h. Therefore, each turbine might produce electricity equivalent to six one-thousandths of a percent of the state's electricity needs. In other words, almost 16,000 of them would be required to provide only 1% of the state's needs.

Letters of note
A couple recent letters in the the North Adams (Mass.) Transcript are illustrative of the diversion (i.e., evasion) and misrepresentation typically seen in response to critics of industrial wind power.
Christopher Vadnais criticizes an earlier piece by Clark Billings for ignoring the many problems and inefficiencies of oil and coal use. The issue, of course, is not oil and coal but wind power, and Vadnais neglects to show how it would move us away from, much less improve the efficient use of, oil and coal. Particularly as he simply ignores Billings' point that only 3% of our oil goes to electricity production, generating less than 2.5% of it.
(Vadnais does correctly note an error in Billings' piece, in which he confuses grid capacity with actual production or demand.)
There is an assumption among many pro-wind people that to point out the shortcomings of industrial wind power is to ignore the problems of coal burning and nuclear fission. In fact, it is sincere concern about pollution and sustainability that compels one to make sure the expensive and disruptive construction of thousands of giant wind turbines on formerly nonindustrial, even wild, sites will actually be worth it. To find that it's not is not to express satisfaction with things as they are, it is simply to conclude that industrial wind power is not a solution.
To insist in response that at least wind power is a sign that we're doing something is just infantile and absurd.
Simon Zelazo starts with a personal note about how much he enjoys visiting the Searsburg (Vt.) facility and recently "had the pleasure" of visiting the turbine in Hull (Mass.) and experiencing its mesmerizing "whomp, whomp." He describes the sad interruption of his revery by an airplane, apparently meaning thus to dramatize the need for large-scale wind power. Unfortunately, the airplane -- representing one of the biggest sources of man-made greenhouse gases and one that would be totally unaffected by a small alternative source of electricity -- only illustrates the futility of such windmills as the one at Hull or the dozens proposed for the Berkshires.
The rest of the letter echos the usual industry propaganda.
First, that opposition vanishes after a wind plant is installed, handily ignoring the fact that it doesn't -- as the growing reports of ill experience attests -- along with the fact that most people are stuck where they live and tend to try reconciling themselves to the situation. The main opposition group in Denmark is called "Neighbors of Windmills."
Second, that low-frequency noise is not a problem, despite plenty of personal testimony and the lack of any systematic study. The quote from Geoff Leventhall, who has reported on the effects of low-frequency noise for the U.K. Department for Environment, Food and Rural Affairs (Defra), is found in an anonymous paper by the British Wind Energy Association and is referenced only as "personal communication." Leventhall has apparently not actually studied low-frequency noise from wind turbines, so his "personal communication" is not backed up by any data. In fact, his work for Defra makes it clear that low-frequency noise is a serious annoyance and stress problem that is generally underestimated. He points out that in the U.K. sound regulations are meant to protect only 80-90% of the population but concludes that is inadequate for low-frequency noise.
Third, ice risk. Zelazo claims there has never been injury from ice throw, and that homes are far enough away. That does not address the fact that a large area around each turbine is effectively taken from public use. As Hoosac developer John Zimmerman has written about Searsburg, "When there is heavy rime ice build up on the blades and the machines are running you instinctually want to stay away. ... They roar and sound scarey. One time we found a piece near the base of the turbines that was pretty impressive. Three adults jumping on it couldn't break. It looked to be 5 or 6 inches thick, 3 feet wide and about 5 feet long. Probably weighed several hundred pounds. We couldn't lift it."
Zimmerman has also stated, "Wind turbines don't make good neigbors."
((((((((((()))))))))))
In other news, Bruce Giffin, CEO of the Illinois Rural Electric Cooperative, is excited by the impending connection of a large turbine west of Pittsfield.
He explained that even when the wind is not blowing hard the turbine is able to build torque and store energy, and even when the blades are not moving at all the turbine is still producing electricity.
A remarkable turbine indeed!

"Not surprised"
There's a brave letter in the St. Johnsbury (Vt.) Caledonian-Record today about the show of outrage over a particularly horrendous instance of animal abuse in Lyndonville. It is similar to what Joe Bageant wrote about why liberals hate Bush even as they go along with almost everything he does, namely, he shows the true face of the power they enjoy. So, too, did the abuse of Kacy show the true face, the inevitable consequence, of most people's every-day attitude towards animals.
"If God created it, it feels pain. I just don't get people's way of thinking and please don't take offense at what I am going to say. But then again, if the shoe fits wear it. When you teach a child to kill (hunting) an animal at an early age and call it sport then why are you so surprised over this. How are they supposed to distinguish the difference."category: animal rights

"Are you a man or a mouse?"
Jeremy Rifkin writes in The Guardian today about frightening developments in the development of lab animals: mice with human brains, pigs with human blood, sheep with human livers and hearts. He describes speculation about creating a human-chimpanzee chimera. Chimpanzees and humans already have in common 98% of their genetic code, and, Rifkin says, and adult chimpanzees has the mental abilities and consciousness of a 4-year-old human.
Of course, a 4-year-old human does not in return have the mental abilities and consciousness of an adult chimpanzee. Which is to say, the chimpanzee has its own consciousness. Rifkin worries about the ethical challenges these chimeras will raise. But if researchers can rationalize their abuse of "98% human" chimpanzees, they will have no problem continuing with "99% human" models, especially if they are the ones that create such an animal.
Rifkin says this can not go farther. But it has already gone too far. He implies that research with "normal" animals is ethically sound. It is not.
Animal research is justified in that it provides "models" for human physiology and even psychology where it would be unethical to experiment on people. Ethics should tell us that such similarity, not to mention the integrity of each animal's own individual and social life, means that using them so is as wrong as using people. Well, the researchers say, they are not in fact so very like us, because human tests are ultimately necessary to prove what was found in the animals. Then the animal tests are not only unethical but ultimately unjustifiable! What does it mean to be human? For many, it seems, it means to be different from the other animals, which we can easily prove by using them for tawdry entertainment, useless research, wasteful food, and decadent clothing -- just as racists and sexists cling to their historical or imagined privileges, to their sense, however deluded, of being above their victims.

parturient montes, nascetur ridiculus mus
a fable . . .
The environmental groups were very worried about the ill effects of fossil and nuclear fuels. They quaked and roared that people must cut back their lavish wasteful lifestyles. The deregulated energy industry did not fear. They showed the environmental groups how they don't have to tell people to give anything up. The industrialists told them that energy from the wind could replace most of the energy from fossil and nuclear fuels.
The environmental groups swelled with pride and joined with industry to build the fabulous turbines. They built them bigger and bigger, more and more of them. The ground shook, trees fell, wild animals fled as the giant wings began to roar with the wind. People were full of awe. They fell to their knees with wonder.
And like the mountain that labored to produce but a little mouse, the thousands of wind turbines -- hundreds of feet high, covering landscapes in every direction, swallowing billions of dollars of resources -- produced but a ridiculous trickle of electricity.
Aesop's crowd laughed at their credulity and returned to their homes. Horace warned poets about promising a mountain lest only a mouse emerges from their pen. The energy industry, however, promises even bigger mountains, and the environmental groups won't admit their folly as long as more people join them. The people are still on their knees, denying the mouse has already run past.
