1 Wind energy in Germany

2 Renewable energy – what for? Lack of raw materials Pollution of the environment Nuclear power is dangerous Search for renewable energy recorces is important

3 The development of wind energy Spread of windmills during the time of crusades (1) Symbol for American farms (waterpipes) Electrical power stations 1: Kreuzzüge

4 Different types of converters 1: Konverter 2: quirlförmig

5 Model of a wind energy converters nacelle (1) generator swivel (3) 2: Getriebe transmission (2) 3: Drehgelenk blades brake 1: Rumpf

6 Use of wind energy in Germany wind power stations Last year: 3.4 % of electricity production Expectation for the end of 2003:every 20th kilowatt-hour Top position concerning wind energy use

7 Example for a wind power station Windkraftanlage Fröttmaning Draw your attention to the TV set, please...

8 Problems of wind energy Very high costs Very uneffective compared to nuclear power stations chartchart 1: auf dem Festland Lack of space onshore (1) Noise pollution

9 Nuclear power stationsWind energy converters % 3,4% Number of stations Production of electricity [back]back

10 Problems of wind energy Very high costs Very uneffective compared to nuclear power stations chartchart 1: auf dem Festland Lack of space onshore (1) Disturbance of the neighbouring residential areas

11 Perspectives for the future Plans for building new wind power stations offshore Aim:Unique (1) use of renewable energy 1: alleinig

12 Further information on wind energy School project by Dr. Bube For those who are very much interested in wind energy: Wind energy International Trade Fair Hamburg

13 Special thanks to... Dr. Walter Bube You saw: Wind energy in Germany A presentation by Lea Leiss, Franziska Seeberger, Stefan Fischer and Jakob Biechele
