  4. The Power of Wind Curriculum • How can we think like an engineer? • How do we study the wind? • How do we use the wind? • How do geography and community influence wind power projects? • How does wind inspire creativity and design?

  5. How Do Geography and Community Influence Wind Power Projects?[The Oklahoma Version]

  6. So why is it so windy in the southern Great Plains?

  7. But what about Oklahoma specifically?

  17. How do we study the wind?

  18. Measuring Oklahoma’s wind

  19. How Do We Think Like an Engineer?

  20. Power is a function of air density, swept area, and wind speed • Doubling rotor length gets us 22 = four times the swept area and thus four times the power • Since power increases as a cubic function of velocity, we see 23 = eight timesthe power.

  21. A sense of turbine scale Source: Paul Gipe, Wind Energy Basics (Chelsea Green Publishing Co., 1999)

  22. How big is a wind turbine? Hub Weight: 35,000 lbs (17.5 tons, 2 1/3 elephants) Blade Length: 113 feet (wingspan of a 747 jet) Blade Weight: 17,500 lbs (8.75 tons, 1.1 elephants) Total Rotor Weight: 87,500 lbs (43.75 tons, 5 2/3 elephants) COURTESY: OMPA

  23. How big is a wind turbine? 60 TON NACELLE (about the size of a small school bus) COURTESY: OMPA

  24. How big is a wind turbine? THE TOP SECTION WEIGHS 24.5 TONS COURTESY: OMPA

  26. An example from Woodward/Freedom Average ∼800 ft. Between turbine ∼1 mile Source: Image and measurements from Google Earth, http://earth.google.com

  27. Spacing Out:The spatial impacts of projects • American Wind Energy Association estimates total area of ≈ 60 acres/MW of capacity. • ≈ 3 acres (5%) to actual physical occupation of land. • ≈57 acres (97%) to exclusion area for windflow preservation. ¼ section (160 acres) Image from Google Earth
