When Big Wind Gets Dirty

New York State is experiencing something of a clean-energy bonanza—thanks to a 2004 law under which the public utility commission offers favorable contracts to renewable-energy producers, the state already has 451 turbines up and running, with another 840 on the drawing board and Spanish company Iberdrola S.A. announcing that it will spend $2 billion to build hundreds more. Sounds good, right? Well… not exactly. Nick Confessore of The New York Times has an excellent investigative piece today about the wind boom's seamy underbelly:

[I]n the small towns near the Canadian border, families and friendships have been riven by feuds over the lease options, which can be worth tens of thousands of dollars a year in towns where the median household income may hover around $30,000. Rumors circulate about neighbors who can suddenly afford new tractors or trucks. Opponents of the wind towers even say they have received threats; one local activist said that on two occasions, she had found her windshield bashed in.

"My sisters and brothers won’t even talk to me anymore," said Mr. Tacy, who with his wife has become active in recent years in a network of people who oppose the wind companies. "They tear communities apart." Opponents of the farms say their scenic views are being marred by the hundreds of wind towers already in place, some of which stand nearly 400 feet tall. They also complain of the irritating hum of spinning turbines and what they say are wasteful public subsidies to wind companies.

But corruption is a major concern. In at least 12 counties, Mr. Champagne said, evidence has surfaced about possible conflicts of interest or improper influence.

The whole story's very much worth reading. A number of towns in the North Country are in dismal shape economically—Massena, New York, for one, is losing its flagship General Motors plant next year, while Franklin County relies heavily on its five state prisons. Wind power could offer a much-needed salve, creating jobs and offering a nice chunk of income to willing landowners. But a growing number of towns feel like they're being steamrolled—there are few laws regulating turbine construction, and the town officials making these decisions are often nestled up with the wind companies. Already, voters in Brandon and Malone have decided to ban all wind turbines from their towns.

Now, this isn't an argument against wind power, per se—after all, no matter much wind turbines might block scenic views, they don't come anywhere close to doing the sort of horrific damage that mountaintop removal mining has inflicted on West Virginia. Plus, there's that whole global warming thing. (On the other hand, the noise complaints are considerably more troubling—the Oregonian had a story recently on "wind turbine syndrome," exploring the possibility that the low-frequency noise and vibrations from wind machines can trigger headaches, insomnia, irritability, and so forth.) Then again, no one in New York lives in West Virginia, so these arguments only go so far.

Still, no matter what the energy source, it's not surprising that large companies looking to get a bunch of easement agreements in a short period of time are going to engage in unseemly line-crossing. We reported recently on a similar story with the shale-drilling boom in Pennsylvania. I do wonder, though, if there are better ways to structure clean-energy policies here. It might be useful to look at the feed-in tariffs in Germany and Denmark, which aren't too dissimilar from New York's law, but explicitly favor small producers. Those policies have been absurdly successful at ballooning the clean-energy industries, but with a twist: More than 50 percent of all wind projects in Germany are owned by farmers and local cooperatives. I'd be curious to know if that's a way of avoiding some of the corruption issues and community infighting that upstate New York is now seeing.

I think wind energy is good. But noise and ugliness are downsides. I also wonder if anyone has studied climate effects of slowing wind down and recovering the kinetic energy as electricity and, uktimately, heat. It may be that, say, 20 million barrels eqivalent per day of energy recovered from wind will also have an unfavorable climate effect.

You obviously aren't an engineer are you r-ennis? The kinetic energy from wind is being transferred either to turbines or trees.  Turbines will have absolutely no effect on climates (other than the fact you aren't spewing carbon into the atmosphere).  In a wind turbine, you want to convert the energy into electricity, not heat. Furthermore that same kinetic energy is going to remain in the system whether or not you harness it. Wow basic science education in the US has declined.

Read that this weekend Brad.  I think it was predicted here on TNR by some forward looking editor that at some point, there would be blowback (pun intended) by citizens and environmentalists regarding how wind turbines change the view and sound scape.

bdespain1, the turbines will produce heat when they produce electricity a fact that has to be accounted for in their maintenance.  We don't have superconductors for windings yet or frictionless bearings.  However, that waste heat most likely will have minimal impact on the environment.

And how the energy is generated, transferred, and used is important, including heat generation.  That's part of the whole global warming argument.  But in this case, that impact from waste heat should be minimal.

Thank you for your gracious answer to my question.You may be certain that capturing wind energy does not have an impact on climate downstream of the turbines and you may be right. But, it is far from obvious, even for someone with a technical background. Your tone lacks even a hint of civility and you should be ashamed of yourself

Here's a piece looking into whether wind turbines could affect the local climate and weather:

My tone lack civility? You proposed that the waste heat from a turbine would affect the climate. It strikes me that many people point out the potential "climate" effects of wind power as a negative often have no problem spewing tons of carbon in the air with a coal burning plant.

We know how much waste heat is produced by turning a turbine, and it is accounted for in their maintenance. Electrical generation is a pretty well known technology.  That same waste heat is produced no matter what is used to spin the turbine.

The article that Brad cites is about the turbulence created by wind turbines in affecting local weather. That's certainly an issue to be aware of when placing turbines but it is far outweighed by the advantages of not burning coal or another fossil fuel when building a power plant.  However the effect that wind turbines have on local weather isn't due to the waste heat of electrical generation.

I second r-ennis' remarks here.  He asked a legitimate, civil question - could there be climate effects due to wind turbines slowing the prevailing wind.  He did not assert or even ask whether the heat thus produced would be implicated in any potential climate change.  I thought bdespain1's answer was uncivil, and frankly, technically nonsensical.

The Science Daily article is indeed about local weather, but it outlines effects that could have climate implications, including increased mixing and evaporation.  It does not address the question r-ennis asked, which remains a legitimate question.  To see why, consider the Midwestern plains of the US.  Summer climate is largely determined by the interaction of relatively cold and dry air masses moving down from Canada, interacting with warm and moist air moving up from the Southeast.  If a mass of turbines strong across the Northern plains reduced the average air mass velocity coming down from Canada by a measurable fractio,  that would shift the average interaction of these fronts North and West, and could alter precipitation and and freezing patterns.

Is that likely?  Based solely on orders of magnitude, I don't think so.  But you'd be a damned fool to bet on my order of magnitude calculation.  You need a circulation model that inserts the wind reduction, mixing and drying due to a massive number of turbines to answer that question.

r-ennis: using windpower is nothing new, of course.  The Netherlands used to be dotted with windmills to keep the water out, and now Northern Netherlands is dotted with wind-turbines - in a couple of hundred years they might be viewed as quaint or cute as well, and in the meantime, they help reduce Dutch dependance on foreign oil, not a bad thing.  As for effects on the local climate - it seems to me that given the relative size of the turbines and the movement of climate fronts (over hundreds of kilometers), the effect out not be significant, and in any event, far less significant than pumping greenhouse gases into the air.

In Iran, many desert cities use "wind capture towers" as cooling mechanisms - at night, you can even make ice at the bottom of the towers.  If you can see pictures of "Yazd" on the net, you can see these towers.  They have been operating for hundreds of years and they have had no impact whatever on the local or regional climate: it's mountains as high as 18000 feet that keeptropic winds and humidity away from the desert, and not 100 foot towers ...

I am in favor of wind energy and I also recognize that, thus far, its effect on climate is insignificant. But, it is now contemplated to convert 20% of our electric power to wind. The energy for this is enormous, equivalent to maybe 2-3 million barrels per day of oil burning equivalent. It is not obvious to me that at this scale, the impact on climate will be negligible. If the issue is settled, then my question has been answered.

r-ennis: the point is not how much of our energy usage we get from wind, but how much of wind and storm generated energy are we tapping in doing so.  A single thunder storm generates enough electricity to power a small town for a month or more.  Let's say you manage to capture the lost energy of a thunderbolt: is that going to have any impact whatever on the movement of clouds that cause the bolt in the first place?  In the same vein, if you capture a small portion of the LOW LEVEL winds at the beach, it is not likely to have any impact on the large-scale front movements that give rise to the wind - some of the wind might be dissipated, but this should be no different than the impact of a forest on the movement of air - if, for example, we let grasslands to be reforested.

r-ennis said:

I understand your point, icarus, to mean that even if we manage to convert 20% of our electric power to wind, it would still be an insignificant proportion of wind energy out there. That sounds reasonable. But, like sdemuth, I still believe the question should be exposed to a formal study, lest we turn part of the Great Plains into a dust bowl or something.

An analogy to your statement would be that using wind to power my sailboat would impact the climate.

It doesn't.  I mean, you're taking the Butterfly effect way too seriously.  Humans are not as omnipotent as all that.  (that's why I'm not fully convinced on the global warming stuff).  A few billion turbines are not going to slow down the earth's rotation or stop weather patterns.
