Where are the environmentalists?

[You know things are bad when you have to depend on conservative lobbyists to sound the alarm about threats to the environment.]

Like a tsunami, the politics of global warming has washed over the State House this past month. As the water recedes, the enormity of the problem has begun to sink in. Everybody is pumped up and ready to do something, anything, to solve the problem. The hard fact remains that in the short term there is not much the tiny State of Vermont can substantially accomplish. This is not to say there's not a problem that should be addressed and that all of us should be more responsible for our planet. Caution and thoughtfulness should be the rule that guides the legislature as they move to answer this problem. Let's be sure the solution doesn't lead to a whole new set of problems. Attempting to place huge 400 foot wind turbines on Vermont's mountain tops is a perfect example.

For almost 40 years, Vermont has carefully created a set of land use laws specifically designed to protect the state's beautiful landscape. From the banning of billboards on Vermont's highways in the early 1970's to the development and implementation of Act 250, an entire generation of Vermont politicos, lawmakers, environmentalists and lawyers has made it next to impossible to build any new structures above 2,500 feet. It is so difficult to build in this state that many believe that had the ski areas not been in existence before Act 250, they would never have been developed. ...

Where are all the environmental organizations that helped develop our land use legacy?  In one fell swoop, behind the cloak of global warming, 40 years of Vermont development control policies are being threatened. The placement of huge wind turbines on Vermont's ridgelines flies in the face of Vermont's land use policies. How can this happen? One legislator put it best, "How can we be seen as leaders in the fight against global warming if we don't have industrial wind farms in the state? We would be no different that any other state."

Arguably the cleanest energy user and one of the most beautiful states in the union, Vermont is very different from any other state. Precisely because of things like Act 250 and related policies, Vermont is a national leader on environmental and land use issues. How can this state turn away from its environmental roots by defacing its ridgelines for a marginal generating technology? Wind turbines perform at only 35% of their potential capacity and require a 100% backup generating system for when wind conditions are less than ideal. Is this about feeling good? There is no compelling reason to promote the construction of industrial wind farms in Vermont. Global warming needs to be addressed, but that should not come at the expense of Vermont's land use policies. Simply put, industrial wind farms that destroy Vermont's picturesque ridgelines are not the solution to global warming.

Whichever way the wind blows

A team from the School of Geography and Geosciences at the University of St Andrews (Scotland) surveyed residents around two sites each in Ireland and Scotland and found higher approval of existing than of proposed wind facilities. They also found that many people approving of the existing facilities had indeed changed their minds from opposing them when proposed.

Have they also changed their whole worldview? According to the BBC ("Residents air views on wind farms," Dec. 12),
The survey also found that opponents and advocates of wind farms saw the world through "different lenses".

Dr [Charles] Warren said: "We focused on people's general environmental attitudes before homing in on the wind farm issue.

"We found that people in favour of wind farms generally viewed environmental issues as global and justified their support on that basis.

"Opponents tended to view the environment as locally conceived and about protecting their local surroundings."
What this illustrates is the amazing coping ability of humans, who are able to rationalize and disregard personal misfortune or local injustice by referring it to a "greater good," however delusional. It is no wonder that people thus resign themselves to what they must now live with.

[A letter in the Dec. 28 Scotsman points out that the study was done in collaboration with the Macaulay Institute of Aberdeen, which runs a consultancy business, Macaulay Enterprises, for the renewables industry. The links on its web site are all pro-industry.]

Ridden by the Wind

The story of industrial-scale wind energy, that is, large wind turbines connected to supply the electric grid, is the same old tale of exploitative industry, of predatory capitalism, of consumerism run riot over the concerns of nature and humanity.

Wind energy does not represent change from a consumption-driven quest of continuing dividends for the investor class. It is a change of brand, nothing more. The same people behind digging up the tar sands of Alberta, drilling in the Arctic, blasting off mountaintops for coal, fracking the ground beneath our feet for methane, mowing down the rain forests, are industrializing rural and wild landscapes with the sprawling tax shelters called wind “farms”.

Like American politics, where choice is limited to which waiter you prefer to serve you from the same Wall Street kitchen (as Huey Long described it), energy policy around the world is “all-of-the-above” with politicians pretending to position themselves against one or another source to flatter different diners. Wind energy operates entirely within that game. As the realities of large-scale wind development — the decimation of habitat, birds, bats, health of human neighbors, and more — have made it harder to sell as “green”, the industry lobby group American Wind Energy Association has strategized: “We need to create a space for the wind energy industry without defining it as an alternative to fossil fuels and coal and that goes beyond being one of many ‘renewables’” (Leadership Council and Board of Directors Meeting, Carlsbad, Calif., Nov. 2, 2011). The reality is that a consumption-based economy dependent on continued “growth” doesn't need alternatives, only more choices: all of the above, whether it works or not. And that imperative excuses all.

As Arkansas Governor Mike Beebe said on June 4, 2012, at the AWEA’s annual convention in Atlanta, “Anyone standing in the way of this industry, frankly, they’re un-American.”

Because there are “important” people making a lot of money in wind, and the opening up of previously undeveloped land will enrich them well beyond wind.

Enron invented the modern wind industry by buying the support of environmental groups for large-scale “alternative” energy and all that makes it profitable: tax avoidance schemes, public grants and loan guarantees, artificial markets for “green credits”, and laws requiring its purchase. Texas Governor George W. Bush was instrumental in getting the first of these implemented at the national level on behalf of his friend Ken Lay, Enron's CEO. Texas is the USA’s leader in wind energy development, not because of some environmentalist vision, but because of the opposite: Wind energy is just one more extractive industry, and with the collaboration of Enron's environmentalists it opens up land normally off limits to such development.

The twisted rationalizations of former environmentalists to excuse the obvious adverse impacts of industrial development in the form of wind “farms” are a study in madness, akin to the military “logic” of having to destroy a village to save it. The typical refrain from the likes of the Audubon Society or Sierra Club — when they acknowledge adverse impacts at all — is that wind energy, by its theoretical and never documented reduction of carbon emissions from other electricity sources, saves more birds etc than it kills. They cling to this even as only the latter is increasingly documented and the former is increasingly clearly not. They further flaunt their moral bankruptcy by dismissing the adverse effects as a drop in the bucket compared to all the other killers of birds etc. And they join the reactionary chorus of the U.S. Chamber of Commerce in presenting their plea to shovel more public money to big energy investors as one for (“American”) jobs (at any [public] cost).

At the same time, neighbors of giant wind turbines who suffer adverse health effects are derided as hysterical or mendacious. The unsurprising acoustic effects of jumbo-jet-size turbine blades cutting through vertical air spaces of almost 2 acres are simply denied. Wind's apologists reverse cause and effect and blame the victims for publicizing noise problems even as ever larger blades are increasingly documented to generate intrusive throbbing and low-frequency noise, both of which not only disturb sleep and raise stress but are increasingly tied to direct adverse physiological and psychological effects. Yet the industry fights all efforts to set even inadequate minimum distances between turbines and homes or noise limits. The CEO of Danish wind turbine manufacturer Vestas, Ditlev Engel, wrote to the Danish Environment Minister on June 29, 2011, against such limits: “At this point you may have asked yourself why it is that Vestas does not just make changes to the wind turbines so that they produce less noise? The simple answer is that at the moment it is not technically possible to do so.” Especially because, as he goes on to note, they are planning even larger machines.

And if human neighbors are treated with such naked contempt in the mad logic of corporate profit growth, pity the wildlife whose last refuges are invaded, divided, and destroyed by big wind (and now big solar as well) — all with the blessing of many environmental groups.

Invaded, divided, and destroyed — nineteenth-century colonialism and twentieth-century globalism are now openly revived against our own communities. Just as the Spanish company Iberdrola steals farmland from the Zapotecas of Oaxaca, and the Indian company Suzlon steals forest from the Adivasis, wind developers in more “developed” countries — in Europe, North America, Australia — prey on their rural populations, pitting paid-off landowners against their neighbors, leaving bitterness and discord, a blighted landscape, shattered peace and quiet, an industrial waste land from which the limited liability companies extract what profit they can and then move on to the next marks.

Industrial wind development may not be the worst scourge on the planet, but that does not excuse it. Big wind is not separate from the rest of exploitative and extractive industry. It is not separate from the persistent efforts of the investor class to hoard for themselves more of the public wealth. It is, however, particularly evil because it presents itself as the opposite of what it is. It is not even an alternative evil: To add insult to injury, wind is not even a good way to generate electricity for the grid: Since it does not blow according to customer demand, it still has to be 100% backed up by other sources.

Break the spell! End the charade!

See the swindle for what it is. Big wind is an enemy of the planet, its animal and plant life, its people. It is a new brand in an old game whose rules were written to ensure one winner only, and it isn't you.

Model large wind energy ordinance

A model ordinance for small wind, from Malone, New York, has been previously presented. The Malone definition of small wind energy systems is more realistic than the one reproduced here. Malone limits small wind systems to 10 kW and to tower heights of 65 feet on parcels of 1-5 acres and 100 feet on parcels over 5 acres. The Malone ordinance also requires 1500-ft setbacks for large wind energy systems if they are forced through despite the ordinance's outright ban. (Manitowoc also produced an ordinance for small wind, but it is highly restrictive because of efforts by wind company representatives on the drafting committee to sabotage the whole law-making effort.)

The Manitowoc County ordinance, which became effect May 1, is notable for its strict limitation of noise to 5 dB(A) above the ambient level at any point on neighboring property. Here are excerpts.

Large Wind Energy System Ordinance

"Large wind system" means a wind tower and turbine that has a nameplate capacity of more than 100 kilowatts or a total height of more than 170 feet, or both.

24.06. Standards

(1) Location. (a) A large wind system may only be located in areas that are zoned A3-Agriculture or PA-Prime Agricultural. (b) A wind tower may not be located within one-quarter mile of any area that is zoned C1-Conservancy or NA-Natural Area or within one-quarter mile of any state or county forest, hunting area, lake access, natural area, or park.

(2) Set Backs. The wind tower in a large wind system and each wind tower in a wind farm system must be set back:

(a) at least 1.1 times the total height of the large wind system from the property line of a participating property.

(b) at least 1,000 feet from the property line of a nonparticipating property unless the owner of the nonparticipating property grants an easement for a lesser setback. The easement must be recorded with the Register of Deeds and may not provide for a setback that is less than 1.1 times the total height of the large wind system.

(c) at least 1.1 times the total height of the large wind system or 500 feet, whichever is greater, from any public road or power line right-of-way.

(10) Lighting. A wind tower and turbine may not be artificially lighted unless such lighting is required by the Federal Aviation Administration. If lighting is required, the lighting must comply with FAA minimum requirements and, whenever possible, be at the lowest intensity allowed, avoid the use of strobe or other intermittent white lights, and use steady red lights. If more than one lighting alternative is available, the alternative that causes the least visual disturbance must be used.

(12) Appearance, Color, and Finish. The exterior surface of any visible components of a wind energy system must be a nonreflective, neutral color. Wind towers and turbines in a wind farm system that are located within one mile of each other must be of uniform design, including tower type, color, number of blades, and direction of blade rotation.

(13) Signs. No wind turbine, tower, building, or other structure associated with a wind energy system may be used to advertise or promote any product or service. No word or graphic representation, other than appropriate warning signs and owner or landowner identification, may be placed on a wind turbine, tower, building, or other structure associated with a wind energy system so as to be visible from any public road.

(14) Noise. The noise generated by the operation of a large wind energy system may not exceed the ambient noise level by more than 5 dB(A) as measured at any point on property adjacent to the parcel on which the large wind energy system is located. The noise level generated by the operation of a large wind energy system will be determined during the investigation of a noise complaint by comparing the sound level measured when the wind generator blades are rotating to the sound level measured when the wind generator blades are stopped.

(15) Flicker or Shadow Flicker. The owner of a large wind system must take such reasonable steps as are necessary to prevent, mitigate, and eliminate shadow flicker on any occupied structure on a nonparticipating property.

Questions and Answers: What's wrong with wind energy?

1. The National Wind Watch home page says, “because of the wind’s low density, intermittency, and high variability, [large-scale wind turbines] do next to nothing for reducing carbon and other emissions or dependence on other fuels”. Could you go into a bit more detail about this and present any links you have for evidence?

The power of the wind is 1/2 of area (turbine rotor diameter) × air density × wind speed cubed. There is a theoretical physical limit (Betz’ law) that no more than 16/27, or 59.3%, of the wind’s energy (power × time) can be captured. Modern wind turbines may reach 50% efficiency, but only within a certain range of wind speeds, which appear to be the average speeds for which the turbines are designed, but at which speeds they generate at only a fraction (around 1/3) of their maximum rate. As the wind speed increases, the rotors are increasingly feathered and efficiency plummets.

The brochure for Enercon turbines includes graphs showing the efficiency vs. wind speed.

In addition to being limited by Betz’ law, wind turbines must not interfere with each other, so they must be spaced quite far apart. The minimum distance is generally considered to be 3 rotor diameters perpendicular to the wind (possible only where wind is unidirectional) and 10 rotor diameters parallel to the wind. See, eg, www.wind-watch.org/documents/?p=984. Thus in an array of, say, 90-meter-diameter turbines (the blades of each machine sweeping a vertical airspace of 1.57 acres), each machine would require 810,000 square meters around it, or 200 acres. From that 200 acres, assuming a 2-MW turbine and an average rate of generation 25% of capacity (see https://wind-watch.org/doc/?p=3427 for U.S. averages; they are generally quite a bit less in Europe), the average power density is only 2.5 kW/acre.

Furthermore, that wind energy is intermittent, meaning other sources of electricity must be available, and variable, meaning other sources must be kept running to be ramped up and down as needed to keep the electricity supply exactly matched to demand. This means that wind is only adding to the grid and then causing other generators to run less efficiently, including burning fuel while not generating electricity. See http://kirbymtn.blogspot.com/2013/10/us-co-emissions-for-electricity-from.html and http://kirbymtn.blogspot.com/2013/11/how-much-does-wind-energy-reduce-carbon.html

2. Pertaining to health — I’ve heard very mixed messages about whether the health effects are of legitimate concern and I would like to hear your take on it. ... Any scientific information would be great!

21 published (peer-reviewed) studies: http://wndfo.net/wts
10 non-industry, non-government reviews: http://wndfo.net/revs

One hitch has been the term “annoyance” as used in these studies. In epidemiology it means to a degree that can cause health problems. The wind industry has instead used its colloquial meaning to characterize the problem as something people just need to get used to.

Even that flies in the face of the evidence that infrasound (frequencies below the threshold of conscious hearing) and low-frequency noise (ILFN) is probably responsible for much of the problem, because research suggests that people who are sensitive to ILFN become more sensitized with continued exposure.

The research showing that people complain more about wind turbine noise than other artificial sources at similar decibel levels is probably explained by the facts that it is unpredictable (depending on wind speed and direction), that it often occurs at night, and that it is a pulsating noise.

Basically, the wind industry is trying to stop research as it has just begun. Because, as the reviews conclude, the preliminary research clearly justifies concern and is already leading to revisions of noise regulations to consider lower frequencies and pulsating patterns. And if such regulations are justified for humans, they would also have to be considered for wildlife ...

3. For my own sanity, I’m wondering why on earth there is so much controversy! How can there be such polar opposite opinions and what is the truth ... in your opinion?

There is a lot of desperation and urgency to remedy the consequences of our high level of energy consumption, and big wind has exploited that, ever since Enron first realized that it could sell wind to environmentalists as an alternative to coal. Since concern about climate change came to dominate mainstream environmentalism after Al Gore’s movie, wind energy has been sold as our salvation. It became a “with us or against us” marker of one’s concern for the environment or sociopolitical team loyalty. Its own adverse impacts (mining, birds and bats, wild habitat) are then dismissed simply as being much less than those of fossil fuels (the other team), ignoring the fact the the reduction of fossil fuel burning because of wind energy is effectively nil, making wind’s impacts — many of them unique, such as the threats to raptors and bats, and the need to build over hundreds of acres at a time in rural and wild places — an addition, not an alternative. Even the American Wind Energy Association once admitted that the most ambitious wind program would only slow the increase of carbon emissions. And for greenhouse gases, there are still the problems of transport and heating. And animal agriculture. And hydrofluorocarbons.

The truth is that there is no free lunch. By approaching the problem with building more instead of using less, wind energy is only perpetuating it. And while people look to wind energy to save the planet, they are more likely to avoid doing things that would make a real difference. They are able to buy Enron-invented “green tags” (carbon credits) to “offset” their impact rather than actually reduce it.

So the polarity is indeed justified and inevitable. Once somebody realizes that wind is a nonsolution, and harmful itself without meaningfully mitigating other harms, it is clear that there is hardly a “middle ground”. And once someone who believes in wind starts to admit that it has drawbacks or that claims for its benefits are overblown, a cornerstone of mainstream environmentalism starts to crumble — and retrenchment becomes all the more fierce to avoid complicating “the message”.

4. One more question: What are viable solutions instead of wind energy, and if wind energy is here to stay what kind of regulations or changes are needed for it to be successful?

Frankly, there probably isn’t a viable solution right now to 8 billion humans consuming ever more resources, particular in a world economic model of “growth”, which even with the modifier “sustainable” is still growth — growth of consumption, growth of waste, and less for the rest of life on the planet. Thursday's Democracy Now had a couple of climate scientists on calling for radical change from that model: www.democracynow.org/2013/11/21/we_have_to_consume_less_scientists.

As for the potential success of wind energy, it would require not only massive building of wind turbines (and all the resources they require) but also an even more massive battery backup system (and all the more resources) and a massive expansion of continent-wide high-capacity transmission lines. In other words, it’s ridiculous. Virtually everything would have to be turned over to wind energy. We would have instead of a war economy a wind economy, where wind energy powers primarily the maintenance of wind power. And we’d still need backup generators!

H.G. Wells wrote, in 1897, “A Story of the Days to Come”:

And all over the countryside, he knew, on every crest and hill, where once the hedges had interlaced, and cottages, churches, inns, and farmhouses had nestled among their trees, wind wheels similar to those he saw and bearing like vast advertisements, gaunt and distinctive symbols of the new age, cast their whirling shadows and stored incessantly the energy that flowed away incessantly through all the arteries of the city. ... The great circular shapes of complaining wind-wheels blotted out the heavens ...
In that story, it is indeed the power company that is in power.

That said, it is a fact that wind turbines are being and will continue to be built, so like National Wind Watch I strongly support effective setbacks (at least 2 km, perhaps 5 km) from homes and noise regulations (that limit nighttime indoor noise to 30 dBA, as the WHO recommends, and limit ILFN and pulsating noise as well). And we oppose opening up otherwise protected land to the construction of the giant machines. Of course, such regulation would not contribute to, but instead would threaten, the “success” of wind energy. It would remain rare and unprofitable, as such an absurd source of energy for the modern world should be, used only in the most desperate of circumstances when nothing else is possible and the cost and harm and low benefit might be justifiable.

Sham citizen wind energy activism in Washington state

"Wind Farms Trump Local Land-Use Laws, Washington Governor, Court Decide", by Penny Rodriguez, Heartland Institute, February 1, 2009:
Todd Myers, director of the Washington Policy Center, is skeptical of the promised benefits of wind power but nevertheless applauded the Washington Supreme Court’s decision.

“In many ways this decision can be seen as the opposite of the facts presented in the U.S. Supreme Court’s 2005 decision in Kelo v. City of New London,” Myers said. “Here we have state government preserving property rights when local governments are trying to restrict them.

“If farmers want to earn money by putting windmills on their property,” Myers continued, “we should honor their right to do so when reasonable. Local decisions are certainly preferable to those imposed from the state or federal level, but individual property rights should be given the highest priority.

“There are problems with our energy policy, including renewable portfolio standards and preferential renewable subsidies. But denying property rights is not the proper way to deal with those problems. I hope the supreme court will apply the same logic when it comes to other permits and not just wind farms,” Myers said.
"Launched in 2003, ["think tank"] Washington Policy Center’s Center for the Environment focuses on free-market solutions to environmental issues."

Todd Myers is also the executive director of Windworks Northwest, which has just produced a 15-minute video about how crucial it is to get more giant wind turbines into Kittitas County.

As one Fennelle Miller states in the film, wind turbines are a community good that require unfettered property rights to impose them on the community.

This cynical exploitation of climate change fears for such a blatant pro-development agenda, this twisting of environmentalism to mean the very opposite, this opportunistic milking of federal and state subsidies in the name of free enterprise ... well, there's nothing new here. It is just a tiresomely predictable part of human history that nobody should think we are ever free of. And it is not surprising, but saddening nonetheless, that so many otherwise perhaps sane and decent people still fall for it.

The Windworks Northwest film also includes "Dr." James Walker, who is described as "president, american wind energy association". Since last year, though, Walker has been the past president of the AWEA board of directors. What the film also does not note is that he is the vice chairman of the board of Enxco, the company on behalf of whose project the film was made.

And the chairman of Windworks is Robert Kahn, whose company managed the permitting process of the Stateline Wind Project for Florida Power & Light in 2000-2002.

Deceit infuses the film, which is little more than a disjointed intercutting of non sequitur sound bites.

Windworks' "Who Are We": "We believe that the number of wind power plants in the Northwest needs to expand because more wind power means less CO2 emissions and greater U.S. energy security." And anyone who questions those reasons, unless he's executive director Todd Myers himself ("skeptical of the promised benefits of wind power"), is a Nimby aesthete. And anyone who supports industrial expansion heedless of neighbors human and wild is an environmentalist voice for freedom.

If anyone doubted that almost everything about big wind is a sham, Windworks Northwest has helpfully made it extra clear.

Wind energy myths on the grid

Michael Goggin has written a paper for the trade group American Wind Industry Association titled "20% Wind Energy by 2030: Wind, Backup Power, and Emissions". It is an attempt to claim -- in the face of conflicting evidence and reason -- that wind energy, even at substantial "penetration", does not require extra "backup" capacity and substantially reduces carbon emissions from other fuels.
The "no reduction in emissions" myth

Wind opponents sometimes argue that wind energy doesn't actually reduce the fuel use or harmful emissions of other power plants. On its face, this claim does not make sense: utility system operators must precisely balance the total supply of electricity with the total demand for electricity at all times, so the electricity produced by a wind plant must be matched by an equivalent decrease in electricity production at another plant.
The unstated part of that equation is that a decrease in electricity production does not necessarily mean an equivalent decrease in fuel use or emissions. In other words, a thermal plant simply diverts its steam past the turbines, but it doesn't stop creating steam. That is because it may take several hours to reheat. Plants that can switch on faster must use more fuel to do so (like stop-and-go city driving versus steady highway driving). Plants that can modulate their electricity production do so by operating at a lower efficiency, i.e., with more emissions.
• In 2007, wind energy in the U.S. reduced CO2 emissions by over 28 million tons, equivalent to taking almost 5 million cars off the road. On average, each Megawatt- hour (MWh) of wind energy -- the amount produced by two typical modern wind turbines in an average hour -- reduces CO2 emissions by 1,200 pounds.
There is no citation for this claim, because it based only on the above assumption that reduction of electricity production is the same as reduction of fuel use is the same as reduction of emissions. It is not based on actual data.
• The U.S. Department of Energy's (DOE) 20% Wind Energy by 2030 Technical Report calculated that obtaining 20% of our electricity from wind energy by 2030 would [emphasis added] cut cumulative CO2 emissions by over 7.6 billion tons.

• The DOE report found CO2 emissions would [emphasis added] be reduced by over 825 million tons in the year 2030 alone, an amount equal to 25% of all electric sector carbon dioxide emissions in that year -- the equivalent of taking 140 million cars off the road.

• The DOE study also found that wind energy would [emphasis added] cut the amount of natural gas used for electricity generation by 50% in 2030.

• A study by the grid operator in Texas found similar results, concluding that adding 3,000 megawatts (MW) of wind energy to the state's grid would [emphasis added] reduce CO2 emissions by about 5.5 million tons per year, sulfur dioxide emissions by about 4,000 tons per year, and nitrogen oxide emissions by about 2,000 tons per year.

• In regions where a large share of electricity comes from coal power, the emissions savings of wind energy can be [emphasis added] even larger. A DOE analysis found that Indiana could [emphasis added] reduce CO2 emissions by 3.1 million tons per year by adding 1,000 MW of wind power.

• The 30 MW Kaheawa wind plant in Hawaii directly offsets power from oil-burning power plants, reducing oil imports by almost 10 million gallons per year.
The company web site cited for this statement actually says: "Kaheawa Wind will [emphasis added] eliminate the use of over 236,000 barrels of oil or 69,000 tons of coal annually." (236,000 barrels = 9,912,000 gallons.) So again, offsetting the electricity production (which is rarely all oil or all coal based) is not the same as reducing fuel use or emissions, and thus it is not actual data cited but conjecture based on incorrect assumptions. In short, these are made-up numbers that have a shaky relationship with reality.
The "backup power" myth

Sometimes wind opponents claim that because wind energy output varies with the wind speed, wind plants require an equivalent amount of "backup power" provided by fossil fuel plants, negating the environmental and fuel savings benefits of wind energy. Understanding why this myth is false requires some explanation of how the electric utility system operates.

Overview of Power Grid Operations

System operators always maintain significant "operating reserves," typically equal to 5-7% or more of total generation. These reserves are used to deal with the rapid and unpredictable changes in electricity demand that occur as people turn appliances on and off, as well as the very large changes in electricity supply that can occur in a fraction of a second if a large power plant suffers an unexpected outage. Instead of backing up each power plant with a second power plant in case the first plant suddenly fails, grid operators pool reserves for the whole system to allow them to respond to a variety of potential unexpected events.
That is exactly why wind energy facilities can not claim to be replacing other sources. Because wind energy production is intermittent and highly variable -- and typically a small percentage of total generation -- the facilities are like "negative demand" to the grid, balanced by the operating reserves.
System operators use two main types of generation reserves: "spinning reserves," (regulation reserves plus contingency spinning reserves) which can be activated quickly to respond to abrupt changes in electricity supply and demand, and "non-spinning reserves," (including supplemental reserves) which are used to respond to slower changes. Spinning reserves are typically operating power plants that are held below their maximum output level so that they can rapidly increase or decrease their output as needed. Hydroelectric plants are typically the first choice of system operators for spinning reserves, because their output can be changed rapidly without any fuel use. When hydroelectric plants are not available, natural gas plants can also be used to provide spinning reserves because they can quickly increase and decrease their generation with only a slight loss of efficiency. Studies show that using natural gas plants or even coal plants as spinning reserves increases emissions and fuel use by only 0.5% to 1.5% above what it would be if the plants were generating power normally.

Non-spinning reserves are inactive power plants that can start up within a short period of time (typically 10-30 minutes) if needed. Hydroelectric plants are frequently the top choice for this type of reserve as well because of their speedy response capabilities, followed by natural gas plants. The vast majority of the time non-spinning reserves that are made available are not actually used, as they only operate if there is a large and unexpected change in electricity supply or demand. As a result, the emissions and fuel use of non-spinning reserves are very low, given that they only rarely run, the fact that hydroelectric plants (which have zero emissions and fuel use) often serve as non-spinning reserves, and the very modest efficiency penalty that applies when reserve natural gas plants actually operate.
There are two important things to note here. First, no-carbon hydro and low-carbon gas are the sources most likely to be used to balance the fluctuating feed from wind turbines. Yet, the industry always compares the equivalent carbon from coal, oil, or automobiles, when any carbon savings would actually be minimal. Second, since wind must be balanced as "negative demand", those other plants would have to be used more. In the case of gas, that means more carbon emissions, not less.
Accommodating Wind Energy

Fortunately, the same tools that utility system operators use every day to deal with variations in electricity supply and demand can readily be used to accommodate the variability of wind energy. In contrast to the rapid power fluctuations that occur when a large power plant suddenly experiences an outage or when millions of people turn on their air conditioners on a hot day, changes in the total energy output from wind turbines spread over a reasonably large area tend to occur very slowly.

While occasionally the wind may suddenly slow down at one location and cause the output from a single turbine to decrease, regions with high penetrations of wind energy tend to have hundreds or even thousands of turbines spread over hundreds of miles. As a result, it typically takes many minutes or even hours for the total wind energy output of a region to change significantly. This makes it relatively easy for utility system operators to accommodate these changes without relying on reserves. This task can be made even easier with the use of wind energy forecasting, which allows system operators to predict changes in wind output hours or even days in advance with a high degree of accuracy.

Moreover, changes in aggregate wind generation often cancel out opposite changes in electricity demand, so the increase in total variability caused by adding wind to the system is often very low. As a result, it is usually possible to add a significant amount of wind energy without causing a significant increase in the use of reserves, and even when large amounts of wind are added, the increase in the use of reserves is typically very small.

The conclusion that large amounts of wind energy can be added to the grid with only minimal increases in the use of reserves is supported by the experience of grid operators in European countries with large amounts of wind energy, as well as the results of a number of wind integration studies in the U.S.
Actually, the experience in Europe is the opposite of this claim. As wind "penetration" increases, the ability of existing reserves to balance it quickly diminishes and more excess capacity has to be added. See www.aweo.org/lowbenefit.html for a summary. The fact is that the wind doesn't always blow, even over a whole continent at the same time. Therefore, the grid has to be built as if the wind isn't there, because so often it won't be. And with the wind turbines added in, the grid needs even more capacity -- and more high-voltage interconnection lines -- to balance that energy.

The bottom line is that very little can be achieved with large-scale wind power on the grid. It simply adds expense and impacts without replacing other expenses or impacts to any degree that can justify it.

Wind farm requires purchase of extra energy

Surprise: Reality doesn't live up to the sales claims. From the Helena (Mont.) Independent Record, June 4, 2006:
New Judith Gap wind farm causing headaches on the grid

The clean, green power from the Judith Gap Wind Farm that debuted last fall has been more intermittent than anticipated.

And that is causing problems for NorthWestern Energy, the utility that must balance supply and demand on its transmission lines. ...

In April, the Western Electricity Coordinating Council [WECC] in Salt Lake City sent a letter to NorthWestern saying that its transmission system may have fallen 3 percent short of its minimum control performance standards of 90 percent. ...

"This is unconfirmed and ordinarily this information isn't even made public," he said. ...

Joel Schroeder worked as project manager for Invenergy Wind LLC's Judith Gap project, the largest of the company's four wind farms. Reached at company headquarters in Chicago, Schroeder said wind is by nature intermittent.

"If you have a storm move in and the wind picks up, that will boost production, or if you have the opposite and the wind drops out, you'll lose power," Schroeder said. "It's completely dependent upon the wind."

Everyone knows wind power is variable and that other backup power from coal or hydro or natural gas is needed to fill in the calm times.

However, the hourly ups and downs are harder to manage than expected, [vice president of wholesale operations at NorthWestern Energy David] Gates said.

"The wind's blowing and in that hour, the output goes from 20 MW (megawatts) to 80 MW," he said. "The average is 50 MW, but as control operator we have to manage that move from 20 to 80 MW (on the transmission lines)." ...

You can store water behind a dam. But you cannot store electricity, and that fact creates lots of challenges for delivering power and pricing power.

Engineers may have more elegant explanations, but you can think of a power transmission line as a teeter-totter.

To keep the board level, the supply of power sitting on one side must balance the demand sitting on the other side.

When there is too much supply, the utility has to sell power right now. When demand outweighs supply, the utility must buy more power right now.

Long-range power contracts that run for years are relatively inexpensive. But, like shopping at a convenience store, buying power on the spot market costs more, often far more.

So variability at the Judith Gap project is costing NorthWestern's consumers more, they just don't know how much yet.

... On May 7, more than 30 energy developers, power company representatives and rural electric cooperative executives met in Helena with Gov. Brian Schweitzer's staff to discuss Montana's energy future.

One topic was how to build more wind farms, yet keep the transmission lines balanced.

Dave Wheelihan, chief executive of the Montana Electric Cooperatives Association, said the gist of that part of the conversation was that NorthWestern has had to buy more short-term power than expected to balance Judith Gap.

"You can go out and contract for it, but the pricing will be interesting," Wheelihan said.

He said the utility has purchased another 15 megawatts of incremental power from Avista Energy to balance the load. ...

"Our purpose is to project potential noise into the community,"

UPC Group, backed by almost $1.8 billion in European financing, is nearing completion of a wind energy facility on Mars Hill, Maine. But the noise complaints have already begun, with just a few of the turbines operating. The Public Service Board hearings for UPC's project in Sheffield, Vt., is currently in progress. From the Barton (Vt.) Chronicle, February 1, 2007 (click the title of this post):
Until now the issue of noise, which some believe should be included in an aesthetic assessment [which has been a farce of denial, self-rationalization, andd dismissal of local sensibilities -- Ed.] has been relegated to studies from competing experts, who often challenge one another's methodology.

But last week, as complaints about turbine noise begins to surface from places like Mars Hill, Maine, where a UPC wind farm recently went on line, a debate has started to shape up over how much weight the board should give tests that measure noise.

On the stand testifying as a panel for UPC were sound experts Chris Menge and Chris Bejedke. They testified that tests they conducted in the area indicated that turbine noises would not have an adverse effect on the community.

"Our purpose is to project potential noise into the community," noted Mr. Menge.

Under the revised layout that cut the original project from 26 turbines to 16, Mr. Bejedke testified that although the new Clipper turbines are bigger, they will produce less noise on the order of one to two decibels. Testimony from the panel also indicated that noise levels would come well under existing Environmental Protection Agency standards. And at high wind speed, according to their testimony, the noise of wind through the trees would tend to mask the noise from the turbines.
[Three decibels is generally described as the smallest difference detectable by human ears in normal conditions, so "one to decibels" will hardly make a difference, especially since being taller the Clipper turbines will project their noise farther.]
Yet, under cross examination from Sutton's attorney, Mr. Hershenson, the panel acknowledged that noise complaints have surfaced in other host communities despite test results. Displaying an article written by Mr. Bejedke that appeared in a trade magazine, North American Wind Power, Mr. Hershenson cited passages showing that complaints over noise began airing as soon as the turbines came on line.

In Lincoln, Wisconsin, for example, the attorney noted that complaints surfaced even when the noise levels were in compliance with the permit. As a result, he added, a moratorium had been imposed throughout the county on wind farms.

Vermont has no standards for noise studies, but according to testimony, a Massachusetts public agency uses as a cap ten decibels over the measured background noise. [Emphasis added] No permit is awarded if the noise exceeds the cap.
[An increase of ten decibels is perceived to be a doubling of the noise level. It has been stated that community concerns generally begin around an increase of six decibels.]
Mr. Hershenson argued there are numerous locations in the Sheffield project where turbine noise would exceed the ten-decibel cap. That was an assertion that Mr. Bejedke rejected.

Argument Monday suggested there may be a bias at work when background samples are collected in rural areas that are quiet.

Most of the complaints at the Lincoln wind farm came during the night. According to expert testimony on the Sheffield project, none of the studies was conducted at night. Mr. Bejedke testified that most of the samplings were collected between 8:45 a.m. and 2 p.m.

However, Mr. Menge contended that if there were a bias, it would work against wind farms. Quiet background noises at night in the country, he said, "would require the wind turbines to be practically silent."
[Exactly! Not only is it quieter at night, sound typically carries farther. Wind turbines don't care if you're trying to sleep. In Oregon, the 10-dB limit was modified to use urban noise levels instead of those of the actual (i.e., rural) site -- this was done at the behest of wind developers, who, as Menge concedes, know that giant moving machines in a rural area will be distinctly, intrusively, and disruptively noisy. So, as with the "issue" of aesthetics, change the law when reality is in the way.]

Gullible for Wind Power

Ketan Joshi writes: "Not all climate 'skeptics' are wind farm opponents, and not all wind farm opponents are climate 'skeptics', but the region in which those two groups overlap is a truly fascinating case study into how we filter evidence according to our respective worldviews."

This is an important acknowledgement that there are indeed wind energy opponents (or 'skeptics') who are not climate skeptics. In his continuing effort to tar wind energy skeptics with the same brush as climate skeptics, however, Joshi ignores the much more dissonant overlap of climate 'believers' and wind energy supporters.

He decries what he sees as gullibility (or worse) of those who 'believe' the evidence against wind, even as he counts on the gullibility of those who 'believe' in wind to support his defense and promotion of it.

Joshi finds it "fascinating" that one can reject the findings of climate science yet accept those of adverse health effects from wind turbines, insisting that there is "a complete lack of evidence" for the latter. The reference he provides is a film – produced by a wind advocacy group with many industry-connected members – showing unaffected hosting landowners. Joshi apparently takes this single piece of evidence completely on faith, despite its overt agenda, even as he completely rejects all testimony of harm (see, for but a few examples, these victim impact statements).

So one notes that Joshi himself exemplifies how evidence is filtered according to one's worldview. In this case, it is easily understandable in that he works for a wind developer. His general claims of scientific rigor are thus called into doubt when he so casually misrepresents the science of wind energy. His devotion to science seems to go only so far as it supports his and his company's interests.

That's obvious, really, to everyone except, apparently, himself. Just as he tars all views of climate skeptics because of their view on climate change, like many that promote the industry he asserts that faith in wind energy unquestionably follows from the acceptance of climate science. Rather than acknowledge any evidence against wind energy, he bolsters his faith in it by lashing on other examples of accepted science, such as the benefit of vaccines and the truth of evolution, shamelessly aligning industry self-interest with the indisputable achievements of Salk and Mendel. Another tactic is to detect not only scientific heresy anywhere in the views of wind power's critics, but also any hint of racism, sexism, xenophobia, homophobia, etc. to further justify ignoring and even mocking the evidence. Even worse, corporate wind defenders often gloat over the money they make and spend and dismiss critics as merely envious, as cynically angling, like themselves, for a big payoff.

This does not, of course, cause the evidence to go away that wind energy is neither a viable energy source nor a meaningful contributor to lower emissions, and that it has a high level of adverse impacts relative to its benefits.

[[[[ | ]]]]

Despite the acknowledgement that "[n]ot all climate 'skeptics' are wind farm opponents, and not all wind farm opponents are climate 'skeptics'", Joshi's main purpose remains the nonsensical defense of wind energy as a good simply because many climate skeptics bash it. By bashing the climate skeptics in return, he avoids addressing their critiques – which many climate non-skeptics share – of wind energy. In short: 'Because they are wrong about climate science, they are also wrong about wind energy.'

But are climate skeptics who support wind power also therefore wrong about the latter? Are climate non-skeptics who agree that wind energy has serious shortcomings also wrong about climate science? At least the latter possibility is blocked by denying that climate non-skeptics really are: 'Because they oppose wind power, they are dishonest about supporting climate science.' In other words, it is really only one's view of wind energy that is tested, because that is in fact the only true interest. For the former question, corporate representatives like Joshi are quite able to separate the issues of climate science and wind power when climate skeptics support the industry (a common situation in the U.S. among legislators at the subsidy trough). [Update, Jan. 29, 2014:  Joshi has decried Greenpeace as "anti-science" on the evidence of their destroying a GMO research crop. But Greenpeace also supports corporate wind power, which is "pro-science" according to Joshi, whose "science" is clearly an ad hoc fetish.]

Circularity is not a concern, because the premise is not what it might appear to be: not climate science, fossil or nuclear fuels, particulate pollution, nor the Koch Brothers. It is simply the desire to erect giant wind turbines wherever possible.

Those who support that goal repeatedly show that their interest is not science, but simply to sell their product. Thus they misrepresent both.

"Alternative" wind energy requires massive new transmission lines

Dec. 9, Grand Island (Nebraska) Independent: "Costs, especially of new power transmission lines, must be taken into account when considering new wind farms, [Nebraska Public Power District spokeswoman Jeanne Schieffer] said."

Dec. 15, Rocky Mountain News: "Building the high-voltage power lines, which carry electricity from generating stations to substations before delivering it to homes and businesses, has lagged the rapid construction of wind farms because of cost, location and regulatory and technical issues. ... A study by the U.S. Department of Energy released in August identified areas of severe transmission constraints, with New England, Phoenix-Tucson, Seattle-Portland and the San Francisco Bay Area topping the list. The second level included Montana-Wyoming and Kansas-Oklahoma."

Dec. 23, Green Wombat: "But renewable energy projects like the huge wind farms to be built in SoCal’s Tehachapi region face a big hurdle: insufficient or non-existent transmission lines to connect the windy and sunny parts of California to the power grid."

Q & A: Wind Energy

The president of National Wind Watch sent us these answers to questions recently posed by a student in Texas.

1.  Most of the prevailing literature on wind energy has been relatively positive, can you comment as to why your organization has chosen to take an oppositional approach?

Answer:  Most of the prevailing literature on wind energy is wishful thinking. If you read it objectively, you begin to notice that all claims of success (other than sales figures) are not backed up by actual data. This is combined with a tendency to dismiss adverse impacts as insignificant or unlikely. Faced with the evidence of adverse impacts, many advocates of wind energy simply deny them. After a while, one realizes that the arguments for large-scale wind energy are for the most part intellectually dishonest and unable to withstand scrutiny.

Since there is little (if any) evidence of good from wind energy, it is our duty to oppose the fruitless and extensive industrialization of rural and wild places by the wind industry.

2.  As of late, Texas has taken the lead in wind energy production. Reports have highlighted the beneficial impact -- both economically and environmentally -- of this relatively recent wind energy "boom". The vast expanse of Texas lands seem ideal for wind farms. So, where is the problem?

Answer:  Where is the proof of these claimed economic and environmental benefits?

Economically, there may be local effects of rents paid to landowners and pay-offs to communities, but that is all paid for by federal and state taxpayers and local ratepayers, who must still pay for keeping up the rest of the grid as much as before along with the added burden of backing up the wind turbines and overbuilding transmission lines to accomodate their occasional surges and shunt their unpredictable supply somewhere it might be needed or until it dissipates as heat.

The environmental benefit is presumably in reducing greenhouse gas emissions, which is assumed (though again without proof) to outweigh local negative impacts on wildlife and landscape. But the savings of greenhouse gas emissions that are claimed are theoretical only and ignore many aspects of the grid that complicate such a possible effect -- namely, an intermittent, variable, unpredictable source such as wind has to itself be balanced to maintain a steady voltage on the line. This adds inefficiencies to the use of fuel by other sources (from more frequent starting or ramping) or may require other sources to "stand by" -- burning fuel to keep the steam ready to generate electricity when the wind drops. In addition, hydropower is the most ideal source to balance wind, or wind's variations are simply allowed to modulate the line voltage within acceptable tolerances -- either case obviously does not affect the burning of fossil fuels.

Even in pro-wind theory, wind energy will never have a significant impact on greenhouse gas emissions. In isolated systems, even the AWEA claims only that wind will slightly slow the growth of emissions, not reduce them. Globally, wind would barely keep up with expanding electricity needs to maintain its less than 0.5% contribution, according to the International Energy Agency's modeling to 2030 ("Renewables in Global Energy Supply", January 2007). Considering that electricity is but one source of anthropogenic greenhouse gases, even the most hopeful theoretical benefit fades toward nothing. In reality, it's likely even less.

Until a significant global environmental benefit can be proven, we must act on the assumption that the local environmental effects can not be justified.

3.  Recently, the Texas General Land Office received funding and permission to start testing and research for offshore wind energy production and technology. What are your views on offshore wind farming?

Answer:  While siting them far offshore mitigates the impact on human neighbors, impacts on seascape and wildlife remain (besides interfering with birds, the turbines' low-frequency noise is likely to disturb fish and sea mammals), as do the very low possible benefits. Offshore construction is more difficult and expensive, and wear and tear on the turbines is much greater -- promising to make offshore wind even more of a boondoggle than onshore.

Transnationals vs. birds and farmers in Mexico's Isthmus of Tehuantepec

From Tierramérica (click on the title of this post), via National Wind Watch:

The Mexican government is preparing a big wind energy project, but peasant farmers and bird experts aren't too happy about it.

The government's aim is for wind-generated electricity -- which now accounts for just 0.005 percent of the energy generated in Mexico -- to reach six percent by 2030. ...

Achieving that goal involves setting up more than 3,000 turbines in Mexico's windiest zone, the Isthmus of Tehuantepec, in the southern state of Oaxaca ...

But erecting the windmills, tall towers with a 27-metre blade span, requires negotiating with landowners, most of whom are farmers. Some have complained that they were taken advantage of when the first wind farm was created in 1994.

Meanwhile, ornithologists experts warn that many bird species are at risk of being killed by the giant blades, which could cause an environmental chain reaction across the continent, because various birds are migratory.

"Everything is bent towards facilitating the wind farms, but there is not much interest in the birds, which in the long term could bring much broader problems," Raúl Ortiz-Pulido, spokesman for the Mexican office of Birdlife International, told Tierramérica. ...

In the environmental standards for wind farms now being debated, the officials propose eliminating the environmental impact studies that other projects require. This requirement would be replaced by a "preventive report", which is of a lower category and reduced scope.

In the introduction of the new norm, which by law must be open for public discussion for 60 days (with the deadline being the end of February), it is recognised that wind turbines can have "impacts on avian fauna".

It states that the head of the project [emphasis added] should make an "inventory of species that utilise the area, detailing their relationships to determine the repercussion of the displacement of some of them, mating seasons, nesting and raising of young."

But some scientists say it would not be enough for the isthmus area. Six million birds fly through Tehuantepec each year, including 32 endangered species and nine autochthonous species. ...

In La Venta, part of the Juchitán municipality in Oaxaca state, is where most of the official plans for wind turbines are concentrated. The impoverished region is home to 150,000 people, most working in farming and livestock.

There the farmers are also upset with the official plans.

"The landowners were fooled with fixed arrangements, ridiculous payments for rent for installing the turbines and impediments to farming. We won't allow any more plans to be carried out," Alejo Girón, leader of La Venta Solidarity Group, told Tierramérica.

The first wind project, La Venta I, began operating in 1994, and in the past two years continued with La Venta II. Now the government of Felipe Calderón has announced that it will open bidding for La Venta III, and others will follow, like the Oaxaca and La Ventosa projects.

They are projects in which transnational corporations like Spain's Iberdrola and France's Electricité have shown great interest, as have local firms like Cemex cement company, which are considering wind turbines for their own energy needs, and in some cases sell their surplus to the Federal Electricity Commission (CFE).

Finalising these plans means convincing the landowners, to whom CFE pays for each one of the 100 turbines already installed in La Venta less than 300 dollars a year, which is 10 to 20 times less than what their counterparts in other countries receive, says Girón.

"The wind projects created almost no new jobs and they don't benefit the residents. Here nothing changed. We remain poor despite the fact that the CFE promised that this would change," Feliciano Santiago, municipal secretary of Juchitán, told Tierramérica.

[For those with Spanish, read two recent press releases from UCIZONI (La Unión de Comunidades Indígenas de la Zona Norte del Istmo) about their struggle, posted at Ibérica 2000. Update: now in English!]

"The beauty of wind farms"

To the editor, New Scientist:

David Suzuki ("The beauty of wind farms," Opinion, 16 April) reminds us of the importance of solving the problem of global warming. But the issue at hand was the charge that industrial wind farms make little significant difference to carbon emissions, which he doesn't even try to refute. Further, his illustration that beauty is in the eye of the beholder -- that factory smokestacks once filled people with pride -- underscores the lack of objective evidence in favor of "windmills."

No buyers for wind energy

People often ask, if wind power is so problematic and expensive (not to mention ecologically destructive in its own right), why do so many utilities support it? The simple fact is that they only support it where the law requires them to.

Australia has met a mandate of 2% of the electricity supply from renewable sources, and now, without an increase in the target, utilities are showing no interest in buying more wind energy.

The following is from "Wind farms shelved" in the May 31 Northern Argus.
Millions of dollars worth of Mid North wind farm projects are being shelved because the Australian Government is holding off boosting renewable energy targets.

Only one proposal is likely to break ground by the end of the year and that's because it has its own "built-in" consumer, having been optioned by Australian Gas and Light.

Other wind farms have not been so lucky and have suspended construction until Canberra's politicians extend the Mandatory Renewable Energy Target scheme.

The targets, set by the Federal Government, call for energy suppliers to source two percent of their power from renewable sources.

This target has, however, just about been met leaving wind farm companies with no inducement to continue with their projects as they cannot guarantee the sale of their energy.

An $180 million wind farm at Waterloo ... has been suspended. ...

A proposal by Wind Prospect for a 170MW wind farm of 85 turbines in the Barunga and Hummocks Ranges, west of Snowtown, ... has also stalled. ...

Of the four proposed projects in the Mid North, only the one at Hallett appears to be moving forward.

"Malone planners hear worries about wind-power rules"

The planning board of Malone, N.Y., is working to devise local laws for industrial wind turbines, which JP Morgan Chase–owned Noble Assets wants to construct 67 of.
But things got a little nasty at the end of the 90-minute session when Noble's attorney Mark Lyons and Managing Director Chuck Hinckley questioned some of the findings Pierpont has published that claim low-frequency noise from wind turbines is a health hazard.

Lyons said he and Hinckley contacted Dr. Geoff Leventhall, the man who wrote the study Pierpont gleaned information from, "and he said the study he did had nothing to do with wind farms.

"He said, 'I can state categorically that there is no significant infrasound from current designs of wind turbines. To say that there is an infrasound problem is one of the hares which objectors to wind farms like to run.'

It is doubtful that Lyons and Hinckley contacted Leventhall. Their quote is pulled right out of an unsigned British Wind Energy Association paper, where it is attributed to "personal communication," though when and to whom is not specified. Noble had even already used the quote in a newspaper ad (Malone Telegram, February 19, 2005).

Nor is the statement backed up by actual data. Leventhall's personal opinion, or peevishness that laymen are getting involved in the issue, does not refute his research for the U.K. Department of Environmental, Farming and Rural Affairs concluding that current noise regulations do not adequately protect the public from low-frequency noise, which he shows to be a serious annoyance and stress problem.

Though Leventhall has already dismissed the issue of infrasound and low-frequency noise regarding industrial wind turbines, he has nonetheless organized a conference on wind turbine noise in general at the Hotel Stuttgarter Hof, Berlin, 17-18 October 2005. Many papers have already been offered, a few specifically about infrasound and low-frequency noise. Clearly the noise issue is still very much alive.

(The news article linked to in the title of this post contains an obvious error, unquestioningly repeating Noble's description of their plan as 67 1.5-MW turbines on about 30 acres of land. Existing and other planned facilities use 30-60 acres per megawatt, so at a minimum Noble's would take up 3,000 acres.)

Lamar!

The Appalachian range in the mid-Atlantic states is being aggressively targeted for industrial wind development. The Allegheny Ridge alone, in the border areas of West Virginia, Maryland, and Pennsylvania, is under assault by plans for at least 1,000 giant turbines. U.S. Senators Lamar Alexander of Tennessee and John Warner of Virginia have introduced the Environmentally Responsible Wind Power Act of 2005. Here are some excerpts from Alexander's May 13 speech.
Our legislation provides for local authorities to be notified and have a role in the approval of the siting of tens of thousands of massive wind turbines that will be built in America under current policies. It also ensures that the federal government does not subsidize the building of these windmills -- which are usually taller than a football field is long - within 20 miles of a military base or a highly scenic location, such as a national park or offshore. ...

One part of our energy debate will be about wind power, which is the subject of our legislation today. This is because several of our colleagues have proposed something called a Renewable Portfolio Standard, or RPS, which would require power companies to produce 10 percent of all their electricity from renewable sources by 2025. These renewable sources are wind, hydro, solar, geothermal and biomass. ...

It is important for our colleagues to know that a Renewable Portfolio Standard or RPS is all about wind. ... Experts agree that the bottom line is that a requirement that electric companies produce 10 percent of their electricity from renewable energy, if it could be achieved at all, would mean that about 70 percent of the increase would come from wind. In other words, we would go from producing about 1 percent of our electricity from wind to 7 or 8 percent.

Testimony before our Energy Committee and most other sources suggest that to produce this much wind energy in the United States could require building more than 100,000 of new, massive wind turbines. We have less than 7,000 such windmills in the U.S. today, with the largest number in Texas and California.

Testimony also indicated that, even without the RPS, if Congress continues its sustained generous subsidy for wind production for the next 10 years, it will guarantee that the U.S. has about 100,000 of these windmills by 2025. According to the Treasury Department, this wind subsidy, if renewed each year for the next five years, would reimburse wind investors for 25 percent of the cost of wind production and cost taxpayers $3.7 billion over those 5 years. General Electric Wind, one of the largest manufacturers of wind turbines, has experienced a 500 percent growth in its wind business this year due to the renewal of the wind production tax credit last year.

I want to make sure that my colleagues know that there are serious questions about how much relying on wind power will raise the cost of electricity, questions about whether there are better ways to spend $3.7 billion in support of clean energy, questions about whether wind even produces the amount of energy that is claimed. My studies suggest that at a time when American needs large amounts of low-cost reliable power, wind produces puny amounts of high-cost unreliable power. We need lower prices; wind power raises prices. We will have an opportunity in our debates and further hearings to examine these questions.

But the legislation we offer today is about a different question: the siting of 100,000 of these massive machines.

The idea of windmills conjures up pleasant images -- of Holland and tulips, of rural America with windmill blades slowly turning, pumping water at the farm well. My grandparents had such a windmill at their well pump. That was back before rural electrification.

But the windmills we are talking about today are not your grandmother’s windmills.

Each one is typically [over] 100 yards tall, two stories taller than the Stature of Liberty, taller than a football field is long.

These windmills are wider than a 747 jumbo jet.

Their rotor blades turn at [well over] 100 miles per hour.

These towers and their flashing red lights can be seen from more than 25 miles away.

Their noise can be heard from up to a half mile away. It is a thumping and swishing sound. It has been described by residents that are unhappy with the noise as sounding like a brick wrapped in a towel tumbling in a clothes drier on a perpetual basis.

These windmills produce very little power since they only operate when the wind blows enough or doesn’t blow too much, so they are usually placed in large wind farms covering huge amounts of land.

As an example, if the Congress ordered electric companies to build 10 percent of their power from renewable energy -- which as we have said, has to be mostly wind -- and if we renew the current subsidy each year, by the year 2025, my state of Tennessee would have at least 1,700 windmills, which would cover land almost equal to two times the size of the city of Knoxville.

If Virginia were to produce 10 percent of its power from wind and the subsidies continue, it would probably need more than 1,700 windmills. These windmills would take up enough land to equal the land mass of three cities the size of Richmond, Virginia.

In North Carolina, to supply 10 percent of electricity from wind if the subsidies continue, it would take up the landmass of the Research Triangle -- the Raleigh, Durham, Chapel Hill area.

According to testimony before our committee, in Tennessee and Virginia, these windmills would work best and perhaps only work at all along ridge tops.

So, if present policies are continued, we could expect to see hundreds of football field sized towers with flashing red lights atop the blue ridges of Virginia, above the Shenandoah Valley, along the foothills of the Great Smoky Mountains, on top of Signal Mountain, and on top of Lookout Mountain and Roan Mountain in Tennessee and down the Tennessee River Gorge, which the city of Chattanooga has just spent 25 years protecting and now calls itself the scenic city. ...

What will this do to our tourism industry? Will 10 million visitors a year who come to enjoy the Great Smokies really want to come see ridge tops decorated with flashing red lights and 100-yard tall windmills?

What happens to electric rates when the federal subsidy disappears?

Who will take down these massive structures if we decide we don’t like them or if they don’t work?

Who is making the money on all this?

Why are some of European countries who pioneered wind farms now slowing down or even stopping their construction in some places?

Clearly there are more sensible ways to provide clean energy than spending $3.7 billion of taxpayers’ money to destroy the American landscape. ...

While we are debating the wisdom of wind policies, these massive turbines are being built across America, 6,700 of them so far, 29 of them in Tennessee. The Tennessee Valley Authority recently announced it had signed a 20-year contract with a group of investors from Chicago to build 18 huge windmills atop a 3,300 foot ridge on Buffalo Mountain in East Tennessee.

So the purpose of our legislation is to give citizens the opportunity to have some say in where these massive structures are located in their communities and to make sure that the Congress does not subsidize the destruction of the American landscape near our national parks or other highly scenic areas or build such tall structures dangerously close to our military bases.

First, the bill ensures that local authorities are notified and have a role in the approval of new windmills to be built in their areas of jurisdiction. This means that at the same time a proposed windmill is filed with the Federal Energy Regulatory Commission, FERC would notify the local authority with zoning jurisdiction. ...

Second, our legislation provides protection to highly scenic areas and to military bases. It does so my eliminating tax subsidies for any windmill within 20 miles of a World Heritage Area (which includes many national parks), a military base or offshore.

Under the bill, placement of a windmill within 20 miles of such a site shall also require the completion of an environmental impact statement. Further, any windmill that is to be constructed within 20 miles of a neighboring state’s border may be vetoed by that neighboring state. In other words, if the neighboring state can see it, and don’t want it, they can veto it.

I believe that during our debates we will find there are better ways to produce a low-cost, reliable supply of American energy than by spending $3.7 billion over the next 5 years requiring power companies to produce energy from giant windmills that raise electric rates, only work when the wind blows, and destroy the American landscape. ...

In the United States of America, Mr. President, the wholesale destruction of the American landscape is not an incidental concern. The Great American Outdoors is an essential part of the American character. Italy has its art. Egypt has its pyramids. England has its history. And we have the Great American Outdoors.

While we debate the merits of so much subsidy and reliance on wind power, we should at the same time protect our national parks, our shorelines and other highly scenic areas, and we should give American citizens the opportunity to protect their communities and landscapes before it is too late.

Environmentalists don't support industrial wind "farms"

The Berkshire Eagle ends an article about the federal energy bill and the nonsolution of drilling in the Arctic National Wildlife Refuge with a quote from Amherst representative John Olver:
Olver, who said global warming "is the most critical environmental issue of the 21st century," is worried that his constituents might agree with Michaels [of the Cato Institute, who argues that we are not running out of fossil fuel]. He seemed perplexed by Massachusetts residents' unwillingness to support proposed wind farms, including one in remote [sic] Fitchburg [a city of 40,000 people].

"For the environmentally conscious people in Massachusetts, the level of opposition to this is really quite startling," he said.
Even if there were still centuries of fossil fuel left, we obviously can't keep digging it up and burning it like there's no tomorrow. Nuclear power, too, has very serious problems of digging, transport, pollution, and waste. Unfortunately, industrial wind power won't get us away from either of these power sources.

A comment on a blog entry by LA Weekly columnist Judith Lewis about the proposed Pine Tree wind facility outside of Los Angeles -- in which she laments the environmental issues but compares it to the alternative, a giant new coal-fired plant in Nevada -- might help explain to Olver why environment-minded people do not support industrial wind power:
The new coal plant ("Granite Fox") that Sempra wants to build in Gerlach is rated at 1,450 MW. It would be great to be make it (and the many more proposed new plants) unnecessary -- through conservation at the user end and increased efficiency at the existing producer end. Or, if we just want to try continuing on as we are, we could build wind turbines instead. At a 20% capacity factor for wind turbines in California, 7,250 MW would be required to equal the annual average output of the Gerlach plant. That's 500 MW more than is currently installed in the entire U.S. Two-thirds of the time, however, that massive wind plant (340-680 square miles) would be producing less than its average output, so you'd still need substantial frequent back-up from a more reliable source. And frequently ramping up and down those other plants diminishes their efficiency, increasing their pollution.

In short, it is unlikely that enough industrial turbines could be built to have a significant impact, and even then they wouldn't have a significant impact. Except in the negative.

Low-frequency noise and vibrations from windfarms

Eleanor Tillinghast of Green Berkshires recently brought to my attention the paper from which the following excerpts are taken.

P. Styles, I. Stimpson, S. Toon, R. England, and M. Wright. Microseismic and infrasound monitoring of low frequency noise and vibrations from windfarms. Applied and Environmental Geophysics Research Group, School of Physical and Geographical Sciences, Keele University, 18 July 2005:
  • Wind turbines are large vibrating cylindrical towers, strongly coupled to the ground with massive concrete foundation, through which vibrations are transmitted to the surroundings and with rotating turbine blades generating low-frequency acoustic signals which may couple acoustically into the ground. (p. 8)

  • Additionally, the blade-tower interaction is a source of pulses at a low repetition rate, which contain components in the infrasound region. The local and surrounding geology, especially layering, may play an important part in determining vibration transmission. (p. 8)

  • [W]ind farms do produce discernible harmonic signals which can be detected over considerable distances. (p. 44)

  • When the windfarm starts to generate at low wind speeds, considerable infrasound signals can be detected at all stations out to c. 10 km. (p. 66)

  • [T]he vibrations experienced on seismometers situated at considerable distances from farms propagate through the ground as high frequency Rayleigh waves and not through the air, and as such must obey the propagation modes and attenuation and absorption laws for geological materials and not air. (p. 67)

  • We have clearly shown that both fixed-speed and variable-speed wind turbines generate low-frequency vibrations which are multiples of blade-passing frequencies and which can be detected ... at considerable distances (many kilometres) from wind farms on infrasound detectors and on low-frequency microphones. (p. 76)

  • At present there are no current, routinely implemented vibration mitigation technological solutions which can reduce the vibration from wind turbines. (p. 90)

Wind industry continues to lie

Here are a couple of examples of the alternate reality in which wind industry executives operate, hoping that the rest of the world will join them.

In today's Daily Mail report about the U.K.'s new sprawling wind energy facility off the coast of Kent, an unnamed spokesman for Renewable UK, responding to criticism that this 13.5-square-mile, £780 million plant will produce at an average of only 35-40% of its capacity, said, ‘You have to bear in mind that coal and gas-fired power stations don’t work at full capacity either – and even nuclear power stations are taken off line.’

He does not mention that other power stations are used according to demand, not the whims of the wind. Using a peaking plant (at full rated power) 35% of the time, that is, when you need it, is very different from wind turbines producing power, at variable rates, whether you need it or not. An average of 35% is meaningless: If it can not be produced on demand, it is worthless. Wind turbines produce at or above their average rate — whatever it might turn out to be — only about 40% of the time — at whatever times the wind wills.

Also in the article, an item in the sidebar says that it "generates power at wind speeds between 8mph and 55mph". Elsewhere in the article, however, it is noted that the the plant will generate at full capacity only if the wind is blowing at 16 metres per second, i.e., 36mph. Below that speed, production falls precipitously. At 8mph, it is barely a trickle. Furthermore, after the wind gusts above 55mph and the turbines shut down, they don't start up again until the wind goes down to 45mph.

Let us now turn our attention to Vermont, where the founder of anemometer maker NRG Systems David Blittersdorf (his wife Jan is still CEO; David went on to Earth Turbines and then All Earth Renewables, which applied for millions of dollars of grants this year, so Mr B got himself appointed to the state committee disbursing the grants ...). As reported by the Rutland Herald, Blittersdorf gave a talk about wind power at the annual meeting of the Castleton Historical Society.

He said that "wind power is practically unsubsidized when compared to power sources like oil and nuclear energy." Federal financial interventions and subsidies in the energy market were examined by the Energy Information Administration in 2008. They found that wind energy received $23.37 per megawatt-hour of its electricity production in 2007, compared with 44 cents for coal, $1.59 for nuclear, and 25 cents for natural gas and oil.

He also said that "many of the objections to wind power, such as danger to birds and concerns about noise, are no longer true due to newer technology". In fact, "newer technology" simply consists of taller towers with larger blades, which now reach well into the ranges of migrating birds, both large and small. Every post-construction survey of a wind energy facility continues to report more deaths than predicted. (And yet permitting agencies and bird protection organizations continue to believe the developers' assessments.) In addition to birds, the toll on bats has become an increasingly alarming concern. The size of modern turbines has also only increased, not decreased noise problems. Everywhere that wind turbines are erected within 2 kilometers (1.25 miles) of homes, people complain of disturbed sleep, consequent stress and irritability, and often worse health problems that may be a direct result of the throbbing low-frequency noise on the balance organs of the inner ear. (And yet permitting agencies and neighbors continue to believe the developers' reassurances; the latest victims of this willful obtuseness reside on the island of Vinalhaven, Maine.) Again, the problems with wind have only become worse with "newer technology"..

And so he said that the only real remaining objection is the aesthetic one: "Some folks don't want to see a wind turbine on a mountain. We have to choose something. By denying wind power, you're supporting coal, oil and nuclear energy."

Bullshit and bullshit. Not to mention, the aesthetic objection is valid, considering that wind turbine facilities are generally built in previously undeveloped rural and even wild areas. You can't have environmentalism without aesthetics. Vermont doesn't allow billboards on the highways. It essentially bans all development above 2,000 feet on the mountains. 400-feet-high machines blasted into the ridges and connected by wide straight heavy-duty roads are rightly seen as an insult to what we hold dear.

Anyway, many objections — as described about birds, bats, and noise — remain. And the benefits to be weighed against those "aesthetic" costs are hard to find. By denying wind power, you're not supporting other forms of energy any more than you are by promoting wind power. Because wind, which answers only to the whims of Aeolus, not to the actual minute-to-minute needs of the grid, has not replaced and can not replace other forms of energy on the electric grid.

David Blittersdorf may think it's worth killing birds and bats, destroying the neighbors' health, and wrecking the landscape in the belief that if we erect ever more wind turbines we might actually see some positive effect (ignoring all the havoc wreaked to get there). But instead he denies that these well documented impacts actually occur. That is quite disturbing.
