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 14000 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 19 14.000 30% 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
