DRAFT
Why energy conservation trumps windmills
Hill Country Observer, Eleanor Tillinghast, February
2005
___________________________________________________
Proposals for wind power plants are springing up
in western Massachusetts, southern Vermont, and upstate New York.[1] In
a few years, we could see some of our most prominent ridgelines and hilltop
farms industrialized with wind turbines. If we cover our mountains and
farms with wind turbines, what will we accomplish? Let's
look at examples of other places that have been converting their countrysides
into industrial zones.
Denmark. Denmark is somewhat smaller than the combined
land area of Massachusetts and Vermont. [2] In the late 1970s, it began
a massive subsidy program to encourage wind power development.[3]
By the end of 2003, Denmark had approximately 4,300 onshore
wind turbines (plus about 200 offshore.) [4] Wind turbines accounted for
more than 24 percent of its installed electrical generating capacity,
yet they produced less than 13 percent of the country's total annual electricity
output.[5]
Since Denmark's wind power is often generated when it
can't be used, most is dumped to neighboring countries, [6] sometimes
below cost or even free.[7] This means all those turbines accounted for
just over 3 percent of actual electricity consumption in Denmark.[8]
Denmark's main fuels for electricity production are coal,
oil and natural gas,[9] and its levels of carbon dioxide, a key greenhouse
gas,[10] have been rising over the past 15 years.[11] Of all the major
European Union countries, it is expected to be the farthest from compliance
with its Kyoto Protocol standards for greenhouse gases.[12]
In 2003, Denmark's average electricity cost for residential
customers was the third highest in Europe.[13] Last year, the national
government cut subsidies to the wind industry, and just five turbines
were built.[14]
Germany. Germany is about twice the size of New England.[15]
Since 2000, its installed wind power capacity, supported by heavy subsidies,[16]
has more than doubled.[17] As of the end of 2003, it had 15,387 wind turbines[18]
that were able to cover just under 4 percent of the country's demand for
electricity.[19]
As Germany has discovered, because of the unreliability
of wind power, so-called "shadow power stations" must be maintained
at a total level of more than 80 percent of the installed wind power capacity.[20]
Germany remains highly dependent upon energy imports, especially oil and
natural gas. This dependency is expected to increase in the future.[21]
Despite all of those turbines, the European Environment
Agency has warned that Germany may exceed its greenhouse gases limit set
under the Kyoto Protocol.[22]
As reported by Bloomberg News, Germany also has volatile
electricity prices because of its high number of turbines. [23] The German
government just commissioned a report which suggests that if Germany goes
forward with its plan to double the number of wind turbines, annual energy
costs for consumers will more than triple.[24]
The report undermines arguments wind power is a good
way to reduce air pollution, because it details how the same clean-air
benefit could be achieved at lower cost by installing modern filters at
existing fossil-fuel power plants.[25]
United Kingdom. The U.K. has 1,186 turbines at 94 locations,[26]
spread over some of its most spectacular landscapes. Collectively, these
turbines produce about as much electricity as one moderately sized natural
gas plant.[27] Scotland, at less than half the size of New England,[28]
has 332 turbines,[29] and 6,472 more have been proposed or are in the
pipeline.[30]
California. California generates nearly one and a half
times as much electricity as the New England states combined. [31] It
has more than 13,000 wind turbines,[32] which, in 2003, produced less
than 1.3 percent of the state's electricity usage. [33]
California continues to have high levels of air pollution,
in large part because of car and truck emissions. [34] Scientists project
that, in five years, a third of the smog-forming ozone over California
will come from Asia. [35]
Vermont. The Searsburg wind power plant in Vermont is
the only industrial-scale facility in New England. [36] Its 11 turbines
are about 10 miles north[37] of the Hoosac wind project proposed by Enxco
in the Massachusetts towns of Florida and Monroe. Built in 1997,[38] its
highest output was in 1999, and production has been dropping ever since
.[39] By the end of 2003, it was operating at about one-fifth of capacity[40]
and generating 30 percent less electricity than promised. [41]
Whether you look abroad, nationally or regionally, the
lesson should be clear: Blanketing our countryside with wind turbines
will not solve any problem. We should focus, instead, on the underlying
issue: the need to curtail escalating energy consumption.
The New England electricity grid operator forecasts that
energy demand in the region will increase nearly 10 percent over the next
eight years.[42]
New York's population will grow less than 4 percent during
that period, [43] but its electricity use is expected to increase more
than 10 percent.[44] Under the state's recently adopted renewable-portfolio
standard (a legal requirement that utilities in New York buy a certain
percentage of their power from "renewable" generating sources),
the impacts will be huge: An estimated 1,850 1.5-megawatt turbines will
have to be built in rural New York by the end of 2013.[45]
That averages to approximately 230 new 34-story wind
turbines a year on New York's mountains and farms. But roughly half of
the projected increase in the state's electricity demand will still have
to be met by conventional sources like nuclear, oil, and natural gas.[46]
What is the cheapest, cleanest, fastest alternative?
Energy conservation and efficiency.[47]
Since its 2001 energy crisis, California has paid people
and businesses to reduce energy use, and consumption has fallen 10 percent.[48]
According to a new study, New England could save billions
of dollars in energy costs, avoid the need to build 28 300-megawatt power
plants, and reduce the emissions of millions of tons of greenhouse gases
if it pursued more energy efficiency measures.[49]
For a state with the population size of Massachusetts,
simply improving the efficiency of appliances and equipment could save
enough electricity to supply 200,000 homes for a year and reduce carbon
emissions by the equivalent of removing 50,000 cars from the road.[50]
Investments in energy-efficient equipment are less risky,
cause fewer environmental problems, and create far more jobs than power
plant construction.[51] In fact, experts suggest the savings from energy
conservation and efficiency should be seen as a new source of energy,
one that costs less than any alternative supply.[52]
Northeastern states have programs that encourage energy
conservation and efficiency. But, as one politician has noted, we've only
scratched the surface.[53] Before we start destroying our last wilderness
areas with wind turbines, let's do the following:
Redirect public funds from building wind power plants
to financing more energy efficiency measures.
Establish stringent, mandatory efficiency standards.
Offer rebates and other incentives to individuals, communities, and companies
that measurably reduce electricity use.
Count electricity reductions toward our Renewable Portfolio Standard targets.
If you really want to cut energy consumption, reduce pollution, improve
public health, and protect our environment, it's time to contact your
elected officials, educate them about the lessons of Denmark, Germany,
and elsewhere, and tell them you want tougher energy efficiency measures
instead of wind power plants.
Otherwise, in the next few years, you'll be looking at
wind turbines in some of your favorite places, with the knowledge that
they're doing little more than funneling your tax dollars to a few lucky
corporations and landowners, and away from better solutions.

[1] In western Massachusetts, wind power plant plans
are underway in the towns of Florida, Hancock, Lenox, Monroe, Orange,
Savoy, and Williamstown, and, possibly, North Adams. In southern Vermont,
the towns of Londonderry, Manchester, and Readsboro are facing proposals.
In upstate New York, numerous counties are wrestling with proposals: Chautauqua,
Erie, Lewis, Otsego, Steuben, and Yates. [Matt Crawford, "Turbines

[5] Denmark has two electricity systems that are not
connected. The two systems are managed by two companies: Eltra in the
West, and Elkraft in the East. Nordel and Elkraft Transmission are the
transmission system operators in West and East Denmark, respectively.
The annual reports of all four companies are available on their websites,
and Elkraft's website has information not contained in its annual report.
In January 2005, Denmark took over ownership of Eltra and Elkraft [http://www.eltra.dk/composite-11286.htm].
Nordel's annual reports contain statistics on the entire
country. The most recent statistics are from 2003:
3,115 MW installed wind capacity, 12,830 MW total installed capacity (=
24.3% of total capacity);
5,560.4 GWh wind production; 43,757.1 GWh total production (= 12.7% of
total production) [http://www.eltra.dk/media(15971,1033)/Nordel%27s_Annual_Report_2003.pdf]
These numbers are reflected closely in the reports of
Eltra and Elkraft.
West Denmark, 2003 [Eltra 2003 Annual Report, p. 24]:
2,374 MW installed wind capacity, 7,457 MW total capacity;
4,363.4 GWh wind production, 27,364.1 GWh total production;
21,043 GWh total consumption
East Denmark, 2003 [Elkraft 2003 Annual Report and website]:
743 MW installed wind capacity;
1,197 GWh wind production, 16,393 GWh total production;
14,717 GWh total consumption

[7] According to the 2003 annual report of Eltra, the
transmission system operator in Western Denmark, "
large wind
power production in periods with low electricity consumption created several
large energy transports, which the neighbouring countries settled at prices
around DKK 0 per kWh." Hugh Sharman notes that this situation also
happened in 2002. [2003 Annual Report, Eltra, p. 22, http://www.eltra.dk/composite-15581.htm;

[8] According to Nordel's 2003 annual report, 5,560 GWh
of wind electricity were produced in 2003. According to expert Hugh Sharman,80%
of that was exported, to neighbors, leaving 1,112 GWh wind electricity
to be consumed in Denmark. 21,043 GWh electricity consumed in West Denmark
+ 14,717 GWh electricity consumed in East Denmark = 35,760 GWh total electricity
consumed in Denmark during 2003. 1,112 GWh ÷ 35,760 GWh = 3.1%
of all electricity consumed in Denmark during 2003 came from wind turbines.

[10] The definition of greenhouse gases from the Energy
Information Administration of the U.S. Department of Energyis as follows:
Those gases, such as water vapor, carbon dioxide, nitrous oxide, methane,
hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride,
that are transparent to solar (short-wave) radiation but opaque to long-wave
(infrared) radiation, thus preventing long-wave radiant energy from leaving
Earth's atmosphere. The net effect is a trapping of absorbed radiation
and a tendency to warm the planet's surface. [http://www.eia.doe.gov/glossary/glossary_g.htm]

its land area is 134,836 square miles. New England's equivalents are:
total area, 70,447 square miles (CT 5,543; ME 35,385; MA 10,555; NH 9,350;

ME 30,862; MA, 7,840; NH 8,968; RI 1,045; and VT 9,250). If using total
area, then Germany is slightly less than twice the size of New England.
If using land area alone, then Germany is slightly more than twice the
size of New England. [William A. McGeveran Jr., editorial director, The

[25] The information for this point comes from a British
translation of a January 2005 article in Der Spiegel, as well as two articles
about the Der Spiegel article from British newspapers. The translation
is given here.
Frank Dohmen and Michael Sauga, "Wind Calculations,"
Der Spiegel, January 2005.
The results of a study commissioned by the federal government
into the expansion of wind force have caused quite a stir: The "green"
electricity propagated by the Red-Green coalition will indeed be considerably
more expensive for the consumers than previously thought. Everything had,
in fact, already been regulated. Over months, representatives of the federal
government, the large energy producing groups and the wind-power sector
had carried out energetic discussions in order to end the smoldering dispute
as to whether a further expansion of wind power made sense or not.
A scientific study was to be set up. A work under the
direction of the federal government's own Agency for Energy (DENA), which
would be able to answer major questions free from the influence of any
ideology: Is the amount of additional wind power planned by the federal
government feasible at all? What costs would arise? Which technologies
must be used in order to feed in the green electricity? What would be
the effects of the wind power on the supply of power in Germany?
Well known scientific institutes such as the Deutsche
Windenergie-Institut (DEWI: German Wind Power Institute) or the Energiewirtschaftliche
Institut zu Köln (EWI: Institute of Energy Economics at the University
of Cologne) were involved, and high caliber external consultants were
entrusted with the checking of the results. When the representatives of
the power industry and the wind power sector met last Monday, it should
merely have been a matter of formalities: the approval of a summary that
would then be presented to the general public.
The meeting led to a confrontation, however. Instead of approving the
largely complete investigation, participants of the meeting have reported
that the representatives of the wind power sector demanded an editorial
revision. Without this, they let it be known to the group, they would
not agree to the publishing of the study.
Probably with good reason: Because what the scientists had brought together
on 490 pages regarding wind power and its expansion is hardly flattering
for the ecological prestige project of the Red-Green coalition. The discussion
regarding the study, which has been made available to DER SPIEGEL, could
bring additional turbulence to the wind power sector, which has already
suffered some setbacks.
It was also hardly helpful when the Green Federal Minister
for the Environment, Jürgen Trittin, joined with the representatives
of the wind power sector in warning against "misinterpretations"
of the results, even before their publication. The figures and the statements
raise delicate questions, even if meticulous attention has been paid to
ensuring that every side can still publicly represent its position while
referring to the expertise.
According to the study, a further financial and technical
strong-arm effort would be required in order to be able to even input
the quantity of green electricity planned by the federal government into
the German electricity network by the year 2015.
845 kilometers of powerful high-voltage routes will have
to be built in the next few years, at a cost of 1.1 thousand million Euro,
in order to be able to integrate the wind parks that will be shooting
out of the ground throughout the federal republic.
Despite substantial investments into improved techniques,
the risks for the supply of power cannot be completely excluded
The quantity of climate-damaging CO2 gas that would be saved by wind power
could be achieved more cheaply with other measures.
The costs that the consumers would have to pay for green
electricity are considerably higher than previously assumed. According
to the study, the "net additional costs" for the increase of
the amount of wind power electricity planned by the federal government
from 2003 to 2015 alone amount to between 12 to 17 thousand million Euro.
The investment for the network and the support of existing inventory is
not even included in this.
The statements made in the study are a blow to the wind power sector in
a situation that was already critical. Throughout the country, the resistance
of the affected population against the increasing "Verspargelung"
of the landscape (turning the German countryside into asparagus fields)
is growing. And even those who wanted to profit from wind power are becoming
increasingly disappointed. Capital investors have had to accept that the
profit forecasts of wind park operators and installation builders have
sometimes turned out to be questionable.
Some companies who, only a short time ago, were celebrated
as the "great white hope", have had to accept sharp setbacks
in the meantime.
In addition, an increasing number of scientists, politicians
and company managers are warning about a possible false path in the energy
policy.
"We are risking a blackout in the supply of power
if we continue with the promotion of renewable energy in this way,"
said the President of the Federal Association for Industry, Jürgen
Thumann, last week. This kind of criticism could be further nurtured by
the DENA investigation.
Because, according to the data collected by the scientists,
the amount of wind power in Germany will be dramatically increased in
the coming years through the statutory promotional measures of the Red-Green
coalition. From around 23 terawatt-hours (in 2003), the amount of wind
power electricity will rapidly increase to more than 77 terawatt-hours
by the year 2015. This would represent more than 16 percent of the electricity
consumption in Germany.
In addition to further "asparagus poles" in
the country, the so-called Offshore Installations in the North Sea and
the Baltic will contribute to the planned increase. But the connection
of the wind parks apparently involves hidden risks.
In the year 2003, according to the study, the incalculable
wind electricity has already led to substantial safety risks. In the winter
months in particular, with their strong winds, "large-area voltage
and network failures could have occurred," which would have led to
considerable "risks for the reliability of the supply to the German
and European grid interconnection."
The wind power sector and Federal Minister for the Environment
Trittin believe that they can avoid such serious dangers in the future.
For example, the regulations for inputting into the network have already
been changed. Furthermore, additional technical measures in the electricity
network and to the individual installations should ensure reliability.
Whether this will succeed in good time and to a sufficient extent remains
to be seen, however. From 2015 at least, according to the DENA paper,
critical situations could arise once again, following a temporary stabilization
in some network areas. The statements are also less flattering for the
argument that is always mentioned as the main reason for the promotion
of wind power: The reduction of the greenhouse gas CO2.
The emission of the climate killers will in fact be considerably
reduced by the avoidance of the use of fossil fuels such as coal, gas
or oil. According to the study, however, this effect could also be achieved
through other technical measures - but considerably cheaper. For example,
if older power stations were modernized and their efficiency was thereby
increased.
Wolfgang Clement, the Federal Minister for the Economy,
warned quite openly against further experiments in the energy policy last
week. For months now, Clement has been involved in an argument with his
government colleague Trittin regarding the further expansion of wind power.
Based on the results of the study, Clement has now also publicly expressed
doubts. The costs for the green electricity, according to the minister,
would increase from today's 1.4 thousand million Euro to 5.4 thousand
million Euro in the year 2015.
One has to ask, says Clement, whether Germany can afford
that.
Trittin's rejoinder was not long in coming. Clement must
have been working with the wrong figures, blustered the Minister for the
Environment. The expertise from DENA actually showed that a further expansion
of wind power was feasible at acceptable costs. The households would be
burdened with a maximum of one Euro per year.
The mollifications of the Minister for the Environment are just as misleading
as the figures of his opponents. In fact, according to the study, the
payments to be made to the operators of wind parks according to the Energy
Input Law (EEG) will increase from an annual amount of around 2.1 thousand
million Euro (2003) to around 5.4 thousand million Euro in the year 2015.
This sum also includes the market price for the corresponding amount of
electricity, however.
This will have to be subtracted from the development
total in order to determine the added costs of wind electricity compared
to conventional electricity. Other costs will also have to be added or
subtracted. For example, the added outlay for standard and reserve energy
in times of low wind, which the large power companies can reallocate to
the running electricity costs. And this is exactly what the authors of
this study have done, in a complex model taking a number of scenarios
into account regarding the development of raw material prices (gas, coal
or oil) in the future.
The result: For the wind electricity that will be produced
in installations that will be additionally built from 2003 alone, the
consumers will have to pay between 1.4 und 2.1 thousand million Euro more
than for conventional electricity from 2015.
For a normal household with an annual consumption of
around 4,000 kilowatt-hours, this would amount to additional costs of
between 15.40 and 19 Euro for the additional wind electricity expansion
according to the study. These amounts only indicate the "lower edge",
however, "as the indirect costs" that result from the promotion
of other regenerative energy and the windmills that already exist in 2003,
"have not been taken into consideration." If these are also
included, an annual "increase in the costs of obtaining electricity"
for a normal household of between around 36 and almost 44 Euro results
for all regenerative energy from 2015.
Calculations of this kind are very different from the
sometimes very different figures that have been mentioned up to now by
the green electricity-lobby and the Green party. They assume that the
price for conventional electricity will increase rapidly and that green
electricity could perhaps become competitive at some time.
It is exactly here that the problem lies. Instead of
openly stating the difficulties and risks that are hidden in the energy
path that is being followed, and the costs that the citizens could really
be asked to pay, the reaction is wheeling and dealing, fiddling and smooth
talking.
There are certainly citizens who would be prepared to
promote wind energy, despite the higher costs, in order to reduce the
current dependency on gas, coal and oil. In general, there is no objection
to the technology itself. At locations with really strong winds, they
can make a contribution - even if considerably smaller - to the supply
of power.
Massive over-promotion and an unbridled expansion, however,
include risks and could cause costs in thousands of millions, which are
documented in the DENA study for the first time.
Whether such realizations will be quickly reflected in
politics is, however, questionable. Economy Minister Clement will, however,
make use of the data from the study in order to make the planned expansion
of renewable energy somewhat more modest than previously planned. It seems
unlikely, however, that he will start this attempt within the current
legislative period.
Because, above the adversaries Clement and Trittin, there
is somebody who wants to avoid a new fundamental conflict between economy
and ecology under all circumstances in the upcoming continuous election
campaign of the next few months: Federal Chancellor Gerhard Schröder.
He wants as much calm as possible in this matter, no wind at all.
Here are the two articles on the Der Spiegel article.

[27] As of February 20, 2005, the U.K.'s 1,186 turbines
represented 888.8 megawatts of installed capacity. Using a very generous
30% capacity factor, that would mean about 267 megawatts of capacity,
the size of a modest combined-cycle natural-gas plant. [http://www.bwea.org/map/index.html]
[28] According to the 2005 World Almanac, Scotland is
30,418 square miles. It's not clear if that means total area or land area,
but the context implies the latter. New England's total area is 70,447
square miles (CT 5,543; ME 35,385; MA 10,555; NH 9,350; RI 1,545; and
VT 9,614), and its land area is 62,810 square miles (CT 4,845; ME 30,862;
MA, 7,840; NH 8,968; RI 1,045; and VT 9,250.) Either way, Scotland is
less than half the size of New England. [William A. McGeveran Jr., editorial

[41] The website of Green Mountain Power Corporation,
the owner of Searsburg, claims that the wind power plant produces enough
electricity to supply over 2,000 average Vermont homes. The website of
the project manager, John Zimmerman, claims the same. The actual number
is 30% lower, the equivalent of less than 1,392 homes. It's worth noting
that commercial and industrial users account for a substantial amount
of electricity demand, but wind power companies typically refer to homes
in order to illustrate equivalent usage.

[45] New York has not yet produced its Phase II report
analyzing wind power's contribution to the state's RPS, so numbers here
are estimates based on other reports and documents. [Richard Piwko, Project
Manager, GE Power Systems Energy Consulting, The Effects of Integrating
Wind Power on Transmission System Planning, Reliability, and Operations,Phase

New York expects onshore wind power plants to generate
6,593,652 MWh annually (43.69% of all renewables) by 2013. GE Power Systems
established different estimated capacity factors for regions, but those
are extremely optimistic, ranging from 25% to 30% and above (see pages
5.3 and 5.4 of the GE report; yet, for example, according to energy expert
Tom Hewson, Fenner's 2003 capacity factor was 19.2%), so I decided to
use the national average of 27%.
The equation is as follows: (MW x 8760 hours in a year)
x .27 capacity factor = 6,593,652 MWh. MW, the unknown factor, is 2,787.77.
Dividing that by 1.5 MW turbines = 1,858.5 turbines.
This figure is probably low, GE Power Systems' study
notes if reliability is to be expected, a 10% penetration in 2008 would
correspond to about 3,300 MW of installed wind generation [p. 3.5]. That
would translate to 2,200 1.5 MW turbines, and, of course, the total number
would escalate through 2013.
[46] As shown in Footnote 44, a 10.64% increase in electricity demand
is expected from 2005 through 2013. In 2005, the renewables percentage
is established at 19.2%, due to rise to 25% (24% mandatory and 1% voluntary)
in 2013. The difference is 5.8%. That is a little more than half (54.5%)
of the projected increase in electricity demand. The rest will have to
be met with conventional fuels. [State of New York Public Service Commission,
