  1. Wind Energy www.wind.appstate.edu

  2. Sizes and Applications • Small (10 kW) • Homes (Grid • connected) • Farms • Remote Applications • (e.g. battery changing, water pumping, telecom sites, icemaking) • Intermediate • (10-500 kW) • Village Power • Hybrid Systems • Distributed Power • Large (500 kW – 6 MW) • Central Station Wind Farms • Distributed Power • Offshore Wind Generation • Stations

  3. World Growth Market Total Installed Wind Capacity 1. Germany: 14000 MW 2. United States: 6374 MW 3. Spain: 5780 MW 4. Denmark: 3094 MW 5. India: 1900 MW World total 2003: 37220 MW Source: WindPower Monthly

  4. Cost of Energy and Cumulative Domestic Capacity Capacity (MW) Cost of Energy (cents/kWh*) *Year 2000 dollars Increased Turbine Size - R&D Advances - Manufacturing Improvements Capacity & Cost Trends

  5. Drivers for Wind Power • Declining Wind Costs • Fuel Price Uncertainty • Federal and State Policies • Economic Development • Green Power • Energy Security

  6.

  7. Benefits • 5 million KWH/yr • 500 homes • $500,000/yr green power • 7.5 million lbs CO2/yr • 8.3 tons NOX/yr

  8. Economic Development Impacts • Land Lease Payments: 2-3% of gross revenue $2500-4000/MW/year • Local property tax revenue: 100 MW brings in on the order of $1 million/yr • 1-2 jobs/MW during construction • 2-5 permanent O&M jobs per 50-100 MW, • Local construction and service industry: concrete, towers usually done locally • Manufacturing and Assembly plants expanding in U.S. (Micon in IL, LM Glasfiber in ND)

  9. 100 80 60 % Available 40 20 0 Year 1981 '83 '85 '90 '98 Reliability of Wind Turbines

  10. Location and Percentage of High Quality Wind Resources in the US Class 6 (4.3%) Class 5 (6.3%) Class 4 & above 27.5%

  11. North Carolina Wind Map

  12. Ashe & Watauga County Wind Classes

  13. Land Areas of Wind Power Classes in 24 Western NC Counties

  14. Wind Resource Analysis by County (acres)Top 5 Counties in Western NC

  15. County Wind Maps for Western NC • True Wind Map Combined With: • Road data • Digital elevation models • Public lands • Appalachian Trail • Town boundaries • Utility grid • Tax parcel maps www.wind.appstate.edu

  16. North Carolina Coastal Resources

  17. Wind Monitoring Activities

  18. Number of Turbines in Class 4/5 Sites @ 80m to produce:

  19. Small Residential Scale Turbines could power1 - 6 houses(3,000 – 60,000 WWH/yr)

  20. Small Wind Initiative

  21. Issues for Wind Energy Issues for Wind • Legal • “ridge law” • park/forest restrictions • Visual Impacts • Attitudes towards Wind • Avian Impacts • Indirect negative economic impacts • real estate values

  22. Wind Activities • Wind Resource Assessment • NC State Wind Map • Anemometer loan program • TVA wind assessment work • NC Wind Energy Assessment Projects • Education • Small Wind Workshops at ASU and Solar Center • Wind Summit in Boone, NC • Anemometer loan program • Small Wind Initiative • Wind Working Group • Economic impact analyses • Environmental and Avian Impact analyses • Legal/Permitting Issues • Attitudinal surveys • Web Site: http://www.wind.appstate.edu/

  23. In conclusion: • Good wind resources in mountains and along coastal areas in all southeastern states, although not widespread, • Technology is available, reliable and economical, • Majority seem to support wind energy, although significant opposition exists, • significant barriers/ concerns, • more possibilities for small wind
