  10. 10. Session # 2 – October 21, 2010 1 1 The background to Wind Power • Where are we now? - 38 GW installed in 2009 - Growing market € +40 bln. expected for 2011 - Attractive export industry: 17.5% of world market with German origin, 100,000 related jobs - Turbine size as a crucial factor, 6 MW-Turbines off the Belgian coast © 2010 Macademia 10
  11. 11. Session # 2 – October 21, 2010 1 The background to Wind Power • Where are we now? - Turbine size as a crucial factor, 6 MW-Turbines off the Belgian coast - The importance of the wind regime (cubic relation between wind speed and wind power) © 2010 Macademia 11
  12. 12. Session # 2 – October 21, 2010 1 The background to Wind Power • Participant experience with Wind Power - What have been positive or negative experiences with wind? - How is the public perception of Wind Energy in your country/region? - Has it changes over the past couple of years? © 2010 Macademia 12
  13. 13. Session # 2 – October 21, 2010 2 1 2 The big topics in Wind Power  Development of Turbine Sizes - New dimension of forces working on turbine and foundations - Impact on life cycle, operational efficiency and reliability - Relatively little experience compared to other machine tool industries - from 2.5 MW upwards (diameters > 110 m) © 2010 Macademia
