EIA Lowers its Forecast for the Contribution of “Wind Energy”
January 30, 2007
by Glenn R. Schleede, Round Hill (VA)
The latest annual energy forecast issued by the US Energy Information Administration (EIA)
indicates that, by the year 2030, wind energy would supply less than 1% of US electric
generation and about 4/10 of 1% of total US energy consumption.
This forecast, which likely overstates the potential contribution of wind energy, helps show that officials of the wind industry and US Department of Energy are misleading the public, media and government officials with their claims that wind might supply 20% of US electricity.

Last December some electrical power generation information for the Wonthaggi wind farm came my way. The information provides the power produced, or used, each hour for each of the 6 turbines between 1 June 06 and 22 June 06. Although it is for a limited period it illustrates, particularly when graphed, where the problem lies with wind power. That is, because it is dependent on wind availability and strength, the power produced is variable and unpredictable, requiring that some other electric power source be available at short notice to supplement what a wind farm produces.

European Wind Integration Study (EWIS) -Towards a Successful Integration of Wind Power into European Electricity Grids
January 15, 2007
by European Transmission System Operators
The support of renewable energy sources (RES) is one of the key issues in
European energy policy. In order to cope with this challenge, European Transmission System
Operators launched a European wide grid study on the integration of wind power, focusing on
measures needed to be taken by legislators, regulators, grid operators and grid users, aiming at
establishing a harmonised set of rules for the integration of wind power. This set of rules is
vital for the secure and reliable operation of the electricity networks in presence of variable
generation. The scope of work covers all the technical, operational and market aspects related
to the integration of large scale wind power all over Europe. Attention will be later focused on
system interaction of various wind turbines types, the effects of their variable power output on
the system and their ability to provide system service to enable the stable operation of an
electricity grid. The final objective is to obtain the necessary information for the technical and operational measures for risk mitigation and the secure operation of the European electricity grid identified by the steady-state and dynamic investigations on electricity grid models which are established within the study. For this, market and regulatory aspects will be taken into consideration.

Less For More: The Rube Goldberg Nature of Industrial Wind Development
December 20, 2006
by Jon Boone, Oakland (MD)
Rube Goldberg would admire the utter purity of the pretensions of wind technology in
pursuit of a safer modern world, claiming to be saving the environment while wreaking
havoc upon it. But even he might be astonished by the spin of wind industry spokesmen.
Consider the comments made by the American Wind Industry Association.s Christina
Real de Azua in the wake of the virtual nonperformance of California.s more than 13,000
wind turbines in mitigating the electricity crisis precipitated by last July.s .heat storm..
.You really don.t count on wind energy as capacity,. she said. .It is different from other
technologies because it can.t be dispatched.. (84) The press reported her comments
solemnly without question, without even a risible chortle. Because they perceive time to
be running out on fossil fuels, and the lure of non-polluting wind power is so seductive,
otherwise sensible people are promoting it at any cost, without investigating potential
negative consequences-- and with no apparent knowledge of even recent environmental
history or grid operations.
Eventually, the pedal of wishful thinking and political demagoguery will meet the renitent metal of reality in the form of the Second Law of Thermodynamics (85) and public resistance, as it has in Denmark and Germany. Ironically, support for industrial wind energy because of a desire for reductions in fossil-fueled power and their polluting emissions leads ineluctably to nuclear power, particularly under pressure of relentlessly increasing demand for reliable electricity. Environmentalists who demand dependable power generation at minimum environmental risk should take care about what they wish for, more aware that, with Rube Goldberg machines, the desired outcome is unlikely to be achieved. Subsidies given to industrial wind technology divert resources that could otherwise support effective measures, while uninformed rhetoric on its behalf distracts from the discourse.and political action-- necessary for achieving more enlightened policy.

Industrial Wind Energy: Ridgeline Footprint and Related Issues
December 16, 2006
by Hugh T. Kemper, Londonderry (VT)
This paper examines Vermont Public Interest Research Group’s (VPIRG) assertion that by 2015 industrial wind turbines on 8.8% (or 46 miles) of Vermont’s ridgelines above 2500 feet could provide 20% of Vermont’s electricity needs. (1) The examination compares VPIRG’s proposal- which is predicated on Vermont’s average electricity consumption- with the utility industry’s standard for measuring wind energy’s contribution to system reliability and peak demand. i.e. its capacity credit. This measurement concludes that for wind energy to provide the reliable generating capacity to meet 20% of Vermont’s peak demand industrial wind turbines would require 44% - 88% (or 226-451 miles) of Vermont’s ridgeline above 2500’.
Wind Energy Will NOT Reduce US Oil Dependence – December 2006 Update
December 9, 2006
by Glenn R. Schleede, Round Hill (VA)
One of the false claims made by “wind energy” advocates is that greater use of wind energy would
reduce US dependence on oil, including oil imports.
In fact, adding more wind turbines will have no significant impact on US oil consumption.
Unfortunately, many well-meaning people (including reporters) and some regulators and political
leaders have accepted – and repeated -- the wind advocates’ false claims about reductions in oil
use. This brief paper explains why the reduced oil use claim is false.

UK Renewable Energy Data: Issue 1 (08.12.06): Vol. 5: Wind
December 8, 2006
by Oswald Consultancy Ltd for Renewable Energy Foundation
Editor's Note: The following are selected excerpts from the Renewable Energy Foundation press release describing this research. The full press release is available via the link below.
Using the new research it is now possible to assess how renewable generators up and down the country are performing. This data, published in five online files; Biomass, Hydro, Landfill Gas, Sewage Gas and Windpower, shows that firm generators are producing high load factors with carefully designed resource use and load following.
However in the wind sector, far and away the most active of all the technologies at present, results vary enormously due to location. The capacities offshore are encouraging, whilst those onshore are generally only superior in locations very distant from the populations requiring the electrical energy.
Although most sites were built on expected capacity factors of around 30%, results include;
19% (approx) capacity factor for the wind turbines at Dagenham, Essex.
9% (approx) capacity factor at the Barnard Castle plant, County Durham.
The best performing wind sites are in the north of Scotland, and on Shetland the wind turbines are producing capacity factors of over 50%.
Using this analysis of the Ofgem data, researchers have also calibrated a model predicting how a large installed capacity of wind power built across the UK would actually perform. The project used Meteorological Office data to model output for every hour of every January from 1994-2006.
The startling results show that, even when distributed UK wide, the output is still highly volatile.
The average January power variation over the last 12 years is 94% of installed capacity. It is an uncontrolled variation decided by the weather.
The average minimum output is only 3.7% or 0.9GW in a 25GW system.
Power swings of 70% in 30 hours are the norm in January.
The governments’ expectation is that three quarters of the 2010 renewables target, and the lion’s share of the ‘20% by 2020’ target will be made up of windpower.[2] However, the new research offers predictions which are in keeping with Danish and German empirical experience and demonstrate the need for a broader spread of investment in the renewable sector. <br.
The report was commissioned from Oswald Consultancy Limited and funded by donation from the green entrepreneur Vincent Tchenguiz.
Campbell Dunford, CEO of REF, said: “This important modelling exercise shows that even with best efforts a large wind carpet in the UK would have a low capacity credit, and be a real handful to manage. This isn’t the best way to encourage China and India to move towards the low-carbon economy. As a matter of urgency, for the planet’s sake, we need to bring forward a much broader range of low carbon generating technologies, including the full sweep of renewables. Wind has a place, but it must not be allowed to squeeze out other technologies that have more to offer.”
