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

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
