Balancing Fluctuating Wind Energy with Fossil Power Stations: Where are the limits?
October, 2002
by W. Leonhard & K. Muller
Wind energy, fed to the grid to save
resources and reduce emissions,
requires control power for balancing
fluctuations; this causes fuel losses in
thermal power stations and limits the
degree of energy substitution. Facilities
for energy storage are needed
when greatly extending wind power
use off-shore, at the same time generating
secondary fuel for stationary
and mobile applications.

Bird migration studies and potential collision risk with offshore wind turbines
March 31, 2006
by Ommo Hüppop et al
This report published by the British Ornithologists’ Union provides an important look at bird migration behavior over water and the potential for collision with offshore wind energy turbines. The authors recommend "abandonment of wind farms in zones with dense migration, turning off turbines on nights predicted to have adverse weather and high migration intensity, and actions to make wind turbines more recognizable to birds, including modification of the illumination to intermittent rather than continuous light, as the most appropriate mitigation measures." An excerpt of the Executive Summary appears below. The full report can be downloaded from this webpage.

Challenges and Costs of Integrating Growing Amounts of Wind Power Capacity into the Grid – Some Experiences Dealing with 12 000 MW in Germany
2003
by Steffen Sacharowitz, Energy Systems Research Group, Technical University Berlin
High annual growth rates over the past years resulted in an installed wind power capacity of
12 000 MW in Germany by the end of 2002 which generated about 17.3 MWh electricity, that is
about 3.7 % of the German electricity consumption. This development was made possible by
laws introducing feed-in tariffs for wind power generation. Due to the fluctuating nature of
wind power generation the feed-in of growing amounts into the grid causes considerable challenges
and costs for affected transmission system operators, who have to ensure a save grid
operation, though basically good working wind power prediction tools exist. The owner of wind
turbines do not have to deal with these problems since the Renewable Energy Act (EEG) ensures
that their generated power is compensated for by fixed feed-in tariffs. In the long run, this is not
a sustainable approach: Wind power needs to compete sooner or later fully with other power
generating technologies at the market and wind turbine owners need to be able to sell a tradable
product. After successfully supporting the development of the wind power technology, an
approach is needed for including the owners of wind turbines in the task of realizing other ways
than simply providing growing amounts of balancing power for wind power feed-in and gradually
face them with the energy economic reality of integrating large amounts of wind power into
the grid.

E.ON Netz GmbH manages 7600 megawatts of wind generation in Germany, representing 41% of the installed capacity for wind in the country. According to this report, wind operated at 18% capacity on average, with the lowest generation of 8 megawatts occurring in May 2005.

E.ON Netz manages the transmission grid in Schleswig-Holstein and Lower Saxony, about a third of Germany, hosting 6,250 MW of Germany's 14,250 MW installed wind-generating capacity at the end of 2003. This report focuses on the operational challenges and costs associated with the intensive use of wind power due to wind's variability and unpredictability.

Lessons Learned: E.ON Netz GmbH, the largest grid operator in Germany, reports in its Wind Report 2005, that "Wind energy cannot replace conventional power stations to any significant extent...The more wind power capacity [on] the grid, the lower the percentage of traditional generation it can replace."

Economic impacts from the promotion of renewable energies: The German experience
September, 2009
by Dr. Manuel Frondel, Nolan Ritter, Prof. Colin Vance, Ph.D. et.al.
Abstract:
The allure of an environmentally benign, abundant, and cost-effective energy source has led an increasing number of industrialized countries to back public financing of renewable energies. Germany’s experience with renewable energy promotion is often cited as a model to be replicated elsewhere, being based on a combination of far-reaching energy and environmental laws that stretch back nearly two decades. This paper critically reviews the current centerpiece of this effort, the Renewable Energy Sources Act (EEG), focusing on its costs and the associated implications for job creation and climate protection. We argue that German renewable energy policy, and in particular the adopted feed-in tariff scheme, has failed to harness the market incentives needed to ensure a viable and cost-effective introduction of renewable energies into the country’s energy portfolio. To the contrary, the government’s support mechanisms have in many respects subverted these incentives, resulting in massive expenditures that show little long-term promise for stimulating the economy, protecting the environment, or increasing energy security. In the case of photovoltaics, Germany’s subsidization regime has reached a level that by far exceeds average wages, with per-worker subsidies as high as 175,000 € (US $ 240,000)

International Experience With Implementing Wind Energy
February, 2006
by Al Howatson and Jason L. Churchill for the Conference Board of Canada
International Experience With Implementing Wind Energy examines the relative costs, advantages and disadvantages of wind generation. In addition, the report explores infrastructure issues, public attitudes toward wind development, and the various policy instruments used to support the development of wind energy in countries that are leaders in implementing wind energy.
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.
