1 Introduction

Today′s Windmills are taller than the cathedrals of the Middle Ages and the cooling towers of the atomic age. They are standing all over Germany and are sharply criticised as well as cheeringly advocated. At present, the discourse of the use of wind energy concentrates on building numerous and large offshore wind farms. In this paper, I will investigate how ′democratic′ is the policy and decision-making process concerning wind energy in Germany. This case study aims to demonstrate the current limits of democracy and suggest how ′more democratic′ practices could be implemented (? 4). In order criticise the policy, it is necessary to describe the political context in advance (? 3). The lead off will be made by some historic and technical aspects of this technology (? 2).

2 Historic roots and technical aspects1

Humans have been using the energy of the wind for centuries. For example, there were over 200 000 windmills all over Europe in the 18t h century. However, the purpose of these windmills was grinding grain and squeezing seeds. The first installation to generate electricity was built by the inventor Charles F. Brush from Cleveland, Ohio in 1888. Apart from some deplorable attempts of the Nazis, wind power in Germany came (back) on the agenda with the oil crisis of 1973. In order to defy the price dictated by the sheiks, there was a lot of research concerning alternative energies. However, the effects are not worth mentioning. Nowadays, there are about 16000 windmills on land in Germany in order to produce electricity. Although this alternative form of electricity production seems ecologically friendly, there are wide spread protests against these highly subsidised monsters. The main arguments are the mutilation of the landscape, insomnia due to the monotonous hum and the disco effect (red lights flashing in the night), the price decline of neighbouring properties, and the considerable number of dead birds.

One possible way out is to put up wind farms offshore. But the offshore installations mean an enormous challenge for the engineers specialised in wind power. Because of the considerable additional open sea costs; the offshore wind parks are only profitable if they far exceed the output of the rotors on land. It is true that the Danes, the Dutch, and the Swedes have put up a couple of smaller offshore installations since 1991 very close to the shore and used the well-tried on land standard turbines. However, Offshore on the German North and Baltic Sea prevail other conditions. There are some technical details to consider:

- Extravagant foundations of up to forty meters in deep water have to defy storms, ice floes, and house-high waves.
- In order to protect the high-tech gearings and control-electronic equipment from the corrosion of seawater, new capsule technologies are required
- In order to transfer offshore electricity to the inland electricity grid, cables have to be laid in the sea ground. These will comprise a quarter of the total costs for the installation of a wind farm. In addition, the generated electro-magnetic fields could affect the animals, in particular the sense of orientation of sea mammals and fish living in this area.
- The problem of technical reliability and maintenance: the breakdowns multiply, especially when there are heavy storms, in these days or weeks the installations are not accessible to reparation crews.

As yet, nowhere on earth spin round offshore windmills of these multi-megawatt types. The pioneer character of this project is often stated as pro argument, because of the prospects of export developed by the German leadership on this technology. However, the pioneer character of this project contains also risks.
