  5. What is a Fossil Fuel???

  6. What is “Renewable Energy?”

  7. Off-Shore Wind Farms

  8. Middelgrunden

  9. Need to Change Perceptions…

  10. 1980’s California Wind Farm • Older Technology • + Higher RPMs • + Lower Elevations • + Lattice Towers • + Poorly Sited • = Bad News!

  11. In the November-December Audubon Magazine, John Flicker, President of National Audubon Society, wrote a column stating that Audubon "strongly supports wind power as a clean alternative energy source," pointing to the link between global warming and the birds and other wildlife that scientist say it will kill.

  12. Impacts of Wind Power:Noise • Modern turbines are relatively quiet • Rule of thumb – stay about 3x hub-height away from houses

  13. Is wind power viable in our area? Areas with annual average wind speeds around 6.5 meters/second and greater at an 80-m height are generally considered to have a resource suitable for wind development.

  14. Early “Windmill” in Afghanistan (900AD)

  15. Jacobs Turbine – 1920 - 1960 WinCharger – 1930s – 40s

  16. Modern Windmills

  17. Orientation Turbines can be categorized into two overarching classes based on the orientation of the rotor Vertical AxisHorizontal Axis

  18. Wacky Designs out there…

  19. Large Wind Turbines • 450’ base to blade • Each blade 112’ • Span greater than 747 • 163+ tons total • Foundation 20+ feet deep • Rated at 1.5 – 5 megawatt • Supply at least 350 homes

  20. Types of Electricity Generating Windmills • Small (10 kW) • Homes • Farms • Remote Applications • (e.g. water pumping, telecom sites, icemaking) • Intermediate • (10-250 kW) • Village Power • Hybrid Systems • Distributed Power • Large (250 kW - 2+MW) • Central Station Wind Farms • Distributed Power KidWind Project | www.kidwind.org
