Windfarms- an ecological and human disaster in the making

A CASE IN POINT: THE VALENCIAN WINDPOWER PLAN "The Valencian windpower plan ("Plan Eólico") was approved July 26th, 2001. It calls for the implantation of 2700 wind turbines in the Comunidad Valenciana, many of them in the mountains of the Costa Blanca. After two years of negotiations behind closed doors, the pieces of the subsidized pie have been allocated. Soon the bulldozers will start destroying the ultimate asset of this region: its unspoiled interior. See the narrow valleys, smell the orange blossom, marvel at the olive groves: they will never be the same. Neither will the craggy mountains, warm shades of amber in the winter sun. All of this will go, marred by industrial structures. The almond trees will bloom under ugly pylons, and we´ll view the cherry blossoms against a backdrop of rotors and power lines."

Estimation of real emissions reduction caused by wind

Liik-emissionsreduction_thumb The aim is to show that the fuel economy and emissions reduction in the power systems consisting mainly of thermal power plants are not proportional with the electricity production of wind turbines. Participation of thermal power plants in the compensation of fluctuating production of windmills eliminates major part of the expected positive effect of wind energy. A method for calculation of real fuel economy and emissions reduction is described and a calculation example basing on Estonian and Danish data is given. Editor's Note: A worthwhile read in its entirely (attached pdf file). Selected extracts appear below.

Wind Farms: Myths and Facts- David Bellamy, a UK botanist, looks at the myths and facts of industrial wind energy from a UK perspective

Bellamy_1__thumb Having had hundreds of queries from park owners, park users and other members of the public concerned about the increasing number of wind farms in the planning pipeline I have put this document together. Please note I have been helping campaign against wind farms for over 10 years so my view are somewhat partisan, however, I urge you to read the following before coming to your own conclusions.

Cap Gemini Ernst & Young launches European deregulation Index

In conclusion, this study has shown that in many countries deregulation is having the expected effect of increased competition leading to price reduction. However, it is evident that pricing in markets depends not just on the status of deregulation, but also on the broader aspects of competition. Key factors here include the balance of supply and demand, generation fuel costs, the learning process that new markets go through, competition within different market segments and the costs of access to transmission and distribution networks. Deregulation is a long-term process that requires sustained attention.

Insects can halve wind-turbine power

Insect_debris_thumb This short report discusses the impact of insect debris build-up on turbine blades and the resulting reduction in performance. Questions remain regarding how the blades are cleaned, whether detergents or chemicals are used in cleaning, the source of water to be used during the process, and whether the waste water is treated.

Darmstadt Manifesto

Darmstadt_manifesto_thumb Issued on September 1, 1998 by The Initiative Group and signed by more than 100 German University professors, the Darmstadt Manifesto On the Exploitation of Wind Energy in Germany demands the withdrawal of all direct and indirect subsidies in order to put a stop to the exploitation of wind energy. The manifesto claims that the exploitation of wind energy promotes the type of technology which is of no significance whatever for the purpose of supplying energy, saving resources and protecting the climate. The money could be put to far more effective use in increasing the efficiency of power stations, in ensuring effective energy consumption and in funding scientific research into fundamental principles in the field of energy. The Darmstadt Manifesto is directed in particular at politicians, environmental organisations and the media.

Wind Power: Capacity Factor, Intermittency, and what happens when the wind doesn’t blow?

Rerl_fact_sheet_2a_capacity_factor_thumb Wind turbines convert the kinetic energy in moving air into rotational energy, which in turn is converted to electricity. Since wind speeds vary from month to month and second to second, the amount of electricity wind can make varies constantly. Sometimes a wind turbine will make no power at all. This variability does affect the value of the wind power……Editor’s Note: This ‘fact sheet’ is, on the whole, a comparatively fair report. The definitions provided for capacity factor, efficiency, reliability, dispatchability, and availability are useful. Its discussion of back-up generation, marginal emissions and Germany & Denmark, however, is disingenuous as is, to a lesser degree, its discussion of capacity factor and availability. IWA's comments (updated October '06) on these issues follow selected extracts from the 'fact sheet' below.
