Stretching and ignoring the facts about wind power

Glenn Schleede has written a new paper about industrial wind energy, mostly looking at the economics: "Stretching or Ignoring Facts and Making Unwarranted Assumptions When Attempting to Justify Wind Energy." It can be downloaded from the National Wind Watch Resource Library. Here is the outline of section D, which concisely lists the issues to be weighed.

D. Facts about wind energy that are often ignored by federal, state and local officials when considering wind energy policies or facilities
 1. Electricity produced by wind turbines is lower in quality and value than electricity produced from reliable generating units.
 2. Building wind turbines will not replace the need for building reliable, dispatchable generating capacity.
 3. Published information on the cost of electricity from wind per kWh generally is not valid or reliable.
 4. True costs of electricity from wind are much higher than often admitted because important elements of cost are ignored.
  a. Federal and state tax breaks for wind energy are part of the true cost of electricity from wind.
   1) Two very generous tax breaks are available from the federal government.
    • The wind production tax credit (PTC) of $0.019 per kWh for electricity produced during the first ten years of a wind facility's operation.
    • The ability to deduct the entire capital cost of a "wind farm" from taxable using 5-year double declining balance accelerated depreciation.
   2) "Wind farms" enjoy other tax breaks from the state.
   3) Other subsidies are also a part of the true cost but are hidden in either tax or monthly electric bills.
  b. The intermittent, volatile and unreliability of electricity from wind turbines also adds to the true cost of that electricity.
  c. Adding transmission capacity to serve "wind farms" adds to customer costs.
 5. Local economic benefits of "wind farms" are generally exaggerated.
 6. Environmental benefits of wind energy are typically overstated.
 7. Wind energy advocates try to ignore adverse environmental, ecological, scenic and property value impacts of "wind farms."

Whole Fools

Whole Foods has now extended their own folly of buying "wind energy credits" by offering them to their customers. To see the absurdity of the scheme, apply it to the food shelf cards that are similarlyly available at many grocery store checkouts.

Buying a $5 food card means that the grocer will give away $5 of food on your behalf. But if it worked like a wind power card, that $5 food shelf card would represent $6.25 of the wholesale price difference between a "gourmet" food item and its mundane counterpart which may cost the grocer, say, $13. The supplier will still sell the gourmet item to grocers for $19.25 but now will get an extra $5.00 because of your generosity (minus the cut for the broker who set this thing up).

It's nice to thus help your preferred suppliers stay in business, but you can not claim to have offset any part of your own good fortune to be able to buy food or -- alternatively -- to have replaced any conventional items on the shelves with the premium product. In fact, nothing is changed except the amount of money the producer makes.

And so it is with wind energy credits, a cynical invention of Enron that "green" hucksters have made their own.

Enron convinced California that the extra cost of wind energy could be sold separately as its "environmental attributes." Then they made sure that the state required the purchase of a certain percentage of renewable energy, to be represented by certificates for those environmental attributes -- green tags. That system is now the norm across the nation. A wind facility still sells its production to utilities at a premium price. In addition, it sells the certificates on a completely separate market. It can sell the electricity twice!

Whole Foods and other companies do not change their or anyone else's energy use by buying wind energy certificates, nor do their customers in buying wind power cards or stickers. They are simply donating a little money to wind companies (such as Electricité de France, Scottish Power, Iberdrola, Florida Power & Light, Goldman Sachs, JP Morgan, etc.) and mostly enriching the green tag brokers, the heirs of Enron.

Exploitation and destruction: some things to know about industrial wind power

by Eric Rosenbloom

First, by industrial wind, I mean facilities of large wind turbines meant to supply the grid, the "pool" of electricity that must constantly balance supply and demand. "Large" is the first thing that demands attention. The machines proposed for Sheffield and Sutton, for example, are now to be 418 feet high: a 256' tower plus a 162' blade radius (with a vertical sweep area of 1.9 acres!). Several of them have to be lit by strobes day and night for airplane safety. The strobing effect of the lights is increased by reflections off the turning blades.

Not only are the height, turning blades, and lights visually intrusive and incongruous with rural and wild landscapes, the blades, generator gears, motors (that turn the machine into the wind and pitch the blades to maintain a constant rpm), and electrical transformers all make noise. From a ridgeline and especially at night, that noise can travel quite far. The French Academy of Medicine and the U.K. Noise Association both say that large wind turbines should not be closer than a mile from any residence.

Along with the readily audible (and artificial) noise that is many times louder than normal rural noise levels, there is a low-frequency aspect that has driven people from their homes. It doesn't affect everyone, but many people complain of headaches, insomnia, and nausea -- enough that several researchers have noted the resemblance to vibroacoustic disease and are documenting the phenomenon as "wind turbine syndrome."

Even as the wind companies deny that these and other impacts exist, their leases and "forbearance" easements with neighbors forbid the signers from complaining about them (or even telling anyone about the terms of the agreements).

The destruction of wild places and rural quality of life includes the wide strong straight roads necessary to transport the massive parts, the tons of steel and concrete in each platform, the clearcutting of several acres around each machine, and new transmission infrastructure (substations and power lines). It follows an all-too-familiar pattern of heedless exploitation. The only "green" the developers are interested in is that of the easy money.

UPC, the "Massachusetts" company targeting Sheffield and Sutton, is in fact backed by the Italian UPC Group. Enxco, which is still fishing for landowners in New England, is part of the consortium Electricité de France. PPM Energy, which bought Enxco's interests in the Hoosac Mountains of Vermont and Massachusetts, is owned by Scottish Power. Horizon Wind and Noble Environmental Power, both active in New York, are owned, respectively, by Goldman Sachs and JP Morgan. Noble has just teamed up with Enxco's former agent to target sites in Vermont as well. Community Energy, currently targeting Lempster, New Hampshire, is owned by energy giant Iberdrola of Spain. Vermont's own Catamount Energy is an international operation owned by Marubeni Power of Japan and Diamond Castle Holdings, a group of investors whose experience includes Enron's glory days.

The major U.S. manufacturer of industrial wind turbines is GE, who bought the business from Enron. Another war profiteer and nuclear power pusher getting into wind is Halliburton, whose Kellogg Brown & Root division boasts of being a leader in offshore wind construction. One should be not a little dubious about "alternatives" or "solutions" offered by the same people who created the mess in the first place. What excites these companies is not so much the window dressing that hides their main activities, though that is indeed important: Think BP's "beyond petroleum" and GE's "ecomagination." Enron, along with their friend George Bush, set up a web of subsidies, market support, and tax schemes that created and almost completely pays for today's wind industry -- moving ever larger amounts of public money into private bank accounts. Enron even invented "green tags" to sell the electricity twice!

These developers creep into a poor community, make deals with landowners, woo the town board with gifts and promises of cash, flattering them as forward thinkers, and only then make their plans public. Unfortunately for them, the internet has made it possible for the neighbors to quickly learn the facts about industrial wind and -- when they see what a destructive boondoggle it really is -- mount a grass-roots opposition campaign. But even if the developer is driven off, a divided and bankrupted community is left. Damage is done in any case.

Rural America is no different to these companies than indigenous communities or "third-world" countries. Enrich a few of the natives, persuade others of your "progressive" intentions, pay for a school or firetruck, pit the rest against each other, and take what you want. In Australia, the Point Pierce Aboriginal community lost 40,000 years of Dreaming (which is, like Vermont's ridgelines, otherwise protected) to the construction of an industrial wind facility. In Mexico, wind companies -- led by Spain's Iberdrola -- have divided the Zapotecos on the Isthmus of Tehuantepec, which is the most important bird flyway on this side of the world (I haven't even mentioned the decimation of birds and bats by these machines, with blades moving 150-200 mph at the tips exactly where they fly). Some of the Zapotecos wrote about the wind companies to a Scottish bird protector who lives in Spain, describing "the imposition of neoliberal megacorporations destroying nature and our cultures." That is what is happening right in our own back yard.

Minuscule benefits

The appalling thing is that industrial wind turbines on the grid bring no benefits that can justify this destruction. They generate an average of only a sixth to a third of their rated capacity. They generate at or above that average rate only a third of the time. The output is highly variable, so other sources on the grid must work harder (burning more fuel less cleanly) to balance it. In most places, the times of high wind do not correspond to times of high electricity demand, so much of the already small production is wasted. The evils of coal and nuclear power are undeniable. Unfortunately, wind will never threaten the steady base supply they provide -- no matter how many giant turbines and interconnected high-voltage transmission lines we fill the landscape with. Nor has a single peak supply plant ever been shut down because of wind on the grid.

The people of Denmark have not allowed a new turbine to be erected in years. Construction has also dramatically slowed in Germany. Spain and The Netherlands recently halted subsidies to big wind. Australia is starting to balk at continuing support. Because opposition only grows in their own countries as the useless and wasteful destruction becomes ever more clear, overseas companies have moved into the U.S. market -- they know we'll ignore Europe's mistakes just as much as we ignore their successes.

But even in the industry's own promotional material, wind remains a marginal source. Conservation and efficiency easily surpass it in actually reducing fuel use, pollution, and greenhouse gas emissions -- and they don't require industrializing our remaining rural and wild places to enrich a few multinational companies and investors and impoverish (not just financially) the rest of us.

More information is available on the web: my own site at www.aweo.org, the coalition of Vermont groups at www.rosenlake.net/vwv, and the coalition of groups throughout the U.S. and the world at www.wind-watch.org.

In closing, a quick word about NIMBYism: that is, supporting a project in principle but not in your own neighborhood. That defines the developers. Most of their opponents are fighting to protect not only their own back yards but those of their brothers and sisters everywhere.

County ordinances establishing setbacks and noise limits for industrial wind turbines

Here a a couple of good regulations for large wind turbines, excerpted from the noted county ordinances.

Shawano County (Wisc.) Wind Energy Conversion System Ordinance

5.5.4. Noise Standard: The noise due to WECU [wind energy conversion unit] operations shall not be greater than 5 dBA above the established background noise level for more than five 5 minutes out of any one hour time period as measured per Appendix A.
5.5.5. Low Frequency Noise or Infrasound Noise: No low frequency noise or infrasound noise from wind turbine operations shall be created which causes the noise level both within the project boundary and a one-mile radius beyond the project boundary to exceed the following limits ...
5.5.6. Pure Tone Penalty: In the event audible noise due to wind turbine operations contains a steady pure tone, such as a whine, screech, or hum, the standards for Audible Noise shall be reduced by five (5) dB(A). ...
5.5.9. Operations -- Low Frequency Noise: A WECU that emits impulsive sound below 20 Hz that adversely affects the habitability or use of any existing dwelling unit, hospital, school, library, nursing home, or other sensitive noise receptor shall be deemed unsafe and must be shut down immediately.


Otsego County (Mich.) Zoning Ordinance Concerning Wind Turbine Generators and Anemometer Towers

18.5.3. Setbacks. Each proposed wind turbine generator or anemometer tower shall meet the following applicable setback requirements:
18.5.3.1. Each wind turbine generator shall be set back from any adjoining lot line a distance equal to 2,600 feet. The Planning Commission may reduce this setback to no less than 2,100 feet. The amount of setback relief approved by the Planning Commission will be based on data provided by the applicant and prepared and certified by a registered Professional Engineer licensed in the State of Michigan, who is practicing in his or her area of competency. Such data shall be subject to review by the County's independent, recognized expert.

18.5.3.2. In addition to the above, a wind turbine generator shall, in all cases, be setback from a public or private road right-of-way or easement a minimum distance equal to six times the height of the wind turbine generator tower as defined in this Ordinance.

18.5.3.3. For any newly proposed wind turbine generator or anemometer tower, a "wind access buffer" equal to a minimum of five (5) rotor diameters shall be observed from any existing off-site wind turbine generator tower.

18.5.19.1. Sensitive environmental areas shall have a setback of between 2 to 5 miles and shall be determined by the Otsego County Planning Commission and the Department of Natural Resources.

18.5.19.2. Scenic areas, including parks, highways, recreational areas, and others as determined by the County and Townships, shall have a setback of not less than 1 mile.
18.5.4. Maximum Height. Then maximum wind turbine generator or anemometer tower height from the base to the tip of the blade at its highest point shall not exceed 200 feet. The Planning Commission may approve an increased height for a wind turbine generator tower, not to exceed 260 feet from the base to the tip of the blade, if all of the following conditions are met:
18.5.4.1. The increased height will result in the preservation of a substantial stand of trees, existing land forms or structures that would otherwise be removed to increase wind velocity.

18.5.4.2. The increased height will not result in increased intensity on lighting of the tower due to FAA requirements.

Wind company trusts government will ignore environment and community and let them build

Putting the lie to their claim of being "green," Toronto wind power developer Skypower is ignoring the finding of the Quebec Environmental Public Hearing Board (BAPE, from the French) against their 114-tower project in northeastern Quebec near the St. Lawrence river.

According to the CBC, the BAPE "concluded Thursday that the turbines would ruin a picturesque view, threaten the region’s natural and wildlife heritage and threaten the agricultural economy."

Skypower's response was to shrug it off and remind people that the decision is only with the Quebec cabinet, which they are confident to sway with the $350,000,000 investment that the project represents.
