  10. 10. Practical Wind Power Social constraints Ecosystem Technological Services Constraints Constraints Environmental constraints Wind Power
  11. 11. Ecosystem Services •  Food:Agriculture, Aquaculture •  Energy Resources Cost Provisioning •  Services •  Other goods Social cost •  Recreation Environmental •  Aesthetics Cultural cost •  Historic •  Cultural Wind Power (WP) Technological cost •  Biological regulation •  Biodiversity maintenance Regulating •  Endangered species maintenanceReference: Karen McLeod and Heather Leslie (2009)Modified .
  12. 12. Wind Farm Siting Index Exclusionary Typology of zones Assess the open space sensitivity of E.G: ZONES each zone to Set back rules Resources and or wind farm constraints Noise •  Airport restriction impact optimization Flicker area (FAA) Social and Environmental WIND FARM WIND FARM Visual Impact Landscape IMPACT SITING INDEX Regions ZONES User Input Tolerance level
  13. 13. Wind Farm Impact Zones Homogeneous area •  E.g: Forest zone •  Regulating: •  Biodiversiy Ecosystem •  Integrity/No Fragmentation services •  Cultural: •  Recreation Ecosystem •  Maximum value = services Destruction of the ecosystem service sensitivity to •  Minimum value = No impact wind farm
  14. 14. STEP 1 STEP 3
  15. 15. Data SourceModel•  Advantages •  complete spatial coverage •  vertical profile•  Disadvantage •  large uncertainty on vertical profileà Measurement: tower + sodar accurate vertical profile
