Concept for a step-by-step extension of the transmission grid in Germany for the connection and integration of wind turbines onshore and offshore taking into account the production and power station developments and the necessary regulating and reserve power. Introduction: A reasonably priced and reliable electricity supply is an important location factor for the development of an economy. Against this background, it is necessary to investigate the demands placed on the entire system for the generation and transmission of electrical energy, which in future must again be optimised for the integration of the inevitably increasing amount of electricity generated from wind energy. The economic effects resulting from this must also be determined. Maintaining the current level of reliability of supply must be included here as an important boundary condition....
They call him the Don Quixote of the Uckermark. But unlike the Spanish literary figure, Hans-Joachim Mengel, a professor of political science at Berlin's Free University, isn't attacking imaginary "giants" in the Iberian hinterland. Rather, he is taking aim at the 400-foot windmills that blanket the German countryside. Mr. Mengel is not alone. Hundreds of citizens' groups have sprung up in Germany to battle "Verspargelung der Landschaft" - a new phrase in the German lexicon - meaning "the transformation of the German landscape into an asparagus field."
They introduced the world to "environmentally friendly" energy, but now some of Europe's "greenest" countries are under pressure to backtrack on wind farms as public anger grows over their impact on the countryside.
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.
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.
