Trends in the global wind energy market
1. Wind energy converter (WEC)
Enercon E-82
• rotor diameter: 82m
• hub height: 79 – 137m
• rated power: 3MW
Remember:
1MW
~ energy for 1.000 househoulds
~ 3.400 people

Trends in the global wind energy market
3. Trends in the golbal market
• every 2nd WEC in USA, China or Germany
• trend of diversification continues
2004: 24 countries with cap. 100 MW
2009: 35 countries with cap. 100 MW
• 10 times more capacity in 10 years

4. Outlook + new challenges
• Offshore wind turbines
• new technology
• new electrical grids required
• high installation costs
• maintenance difficult
• bigger wind farms possible
• better wind conditions
• few countries (12)
• development required
• hugh potential

4. Outlook + new challenges
Before:
• Capacity of wind farm:
5 MW
• number of WECs:
13
• Repowering
Replace older and smaller WEC‘s by bigger WEC with more capacity.
50% less WEC‘S and 50% more profit
11/12
After:
• Capacity of wind farm:
15 MW
• number of WECs:
5

5. Discussion
12/12
• larger turbines
• noise
• collision birds
• spoil the view
• NIMBY
• wind free to use
• clean energy
• 670.000 jobs
• decentral power generation
