Let's look at facts, not hot air, about wind power

Dot Sulack opines at the Asheville Citizen-Times (click here) in an effort to negate the problems with wind energy pointed out by another in an earlier opinion piece. Here are some quick notes about the issues she raises as not issues at all.

Intermittency: "if ... would ... would also ... would be ...." "If ... can ... when ...." How about a study of an existing system? Why so many "if's" when wind turbines are being built right now?

Cost: Most promoters actually want a feed-in tariff to force a higher price for wind. The target of 4 cents/kWh is required by competition and is only possible by taxpayers paying for three-quarters of the cost of building wind and by splitting off the "environmental benefit" as a separate product (i.e., "green tags" or "renewable energy credits"), a trick invented by Enron.

Birds: Birds killed by turbines aren't a problem because other things kill them, too? As pathetic (and potentially sociopathic) an argument as that already is, wind turbines uniquely affect raptors and bats (the latter to such a degree that even the industry shows concern) and tend to erected in migratory pathways, since that's where the wind is. And the more we build them, the worse the effect.

Good for the air and climate: Forgot to provide a link supporting that statement. How many fossil fuel plants have been shut down because of wind on the grid? How much less fuel is burned per unit of electricity consumed because of the addition of wind? I have been unable to find such evidence that wind is "good" for six years now.

Pickens Plan: Con job of the first order. When wind is added to systems without substantial hydro, it needs natural gas plants for the grid to be able to respond quickly to its fluctuations. Rather than replace natural gas for electricity, wind is a plan to use more of it.

The rest is a muddle of more wishful thinking and jingoistic non sequitur, which is par for such pieces.

Appalachian Voices supports blowing up N.C. mountains to ram in wind turbines

Appalachian Voices appears to be an admirable conservation group, but in their avid desire to eliminate air pollution, stop mountaintop removal coal mining, and restore Appalachian forests, they too readily embrace the false promises of large-scale wind power. In an April 23 entry on their blog, they defend themselves against the charge of supporting the destruction of the mountains to erect giant wind turbines:
To imply that wind farms cause the same environmental toll as mountaintop removal is illogical. Wind energy is a proven technology that works, and has a relatively light environmental impact. A study conducted by Appalachian State University showed that wind energy development on a small percentage of North Carolina ridges could produce enough clean energy for 195,000 homes, create 350 green jobs, and have a net economic impact of over one billion dollars.
The claim of illogic depends, of course, on the soundness of the asserted premise that "Wind energy is a proven technology that works".

That is precisely the issue: Wind energy is a mature technology, but it has yet to show meaningful benefit. This is underscored by the study they cite, which concludes that wind development could produce a certain amount of energy. What is needed, however, is a study showing that wind has produced a certain amount of energy, and — crucially — that the contribution reduced greenhouse gas emissions, pollution, coal mining, deforestation, or anything.

In fact, studies of existing wind on the grid show little, if any, beneficial effect. Therefore, although wind's roads and clearcutting may be seen as less than those of mountaintop removal for coal, those impacts are in addition to those of coal. Wind does not replace or even meaningfully reduce coal. There is very little, if any, benefit to justify wind's environmental impacts.

Appalachian Voices admits supporting the blowing up of mountains in western North Carolina to ram in wind turbines. Their defense fails, however, because it depends on a false premise.
