2. Jim Gibson, Electronics Program Coordinator Sue Isermann, Associate VP for Academic Affairs Jamie Gahm, Director of Continuing Education and Business Services Rose Marie Lynch, Communications Instructor

3. IVCC’s Wind Energy Technician Program Two certificates – Basic and Advanced Started Fall 2010 – Classes full Grant funding -National Science Foundation $560,00 -Small Business Administration Congressional Grant $220,000 -U.S. Dept. of Agriculture Rural Development $99,000 -Illinois Clean Energy Commission Foundation $30,000 Certificates to lead to A.A.S. degree

4. Illinois Ranks High in Wind Energy Development 4 th in existing wind power capacity 14 th in wind potential Sources: American Wind Energy Association and National Renewable Energy Laboratory

5. Illinois Ranks High Good infrastructure: transmission lines, transportation Endorsed Renewable Energy Portfolio Standard - 25% of electricity from renewable sources by 2025, 75% of that from wind

6. Wind Energy Technician Jobs 1 technician for 10 – 15 turbines In / near IVCC district -Over 600 turbines -Over 300 permitted for construction Starting wages $24 - $25 an hour

7. Rationale for a Mini Wind Farm in Your Classroom Capitalize on curiosity about visible turbines Utilize hands-on project to focus on various concepts Highlight “green” energy Introduce/reinforce technical knowledge & skills

8. Building a Wind Farm Basics Components of a circuit 1.Source 2.Conductor 3.Control 4.Load

12. Conductor You Will Use

13. Control for a Wind Turbine Source: National Renewable Energy Lab

14. Control You Will Use

15. Load for a Wind Turbine Source: National Renewable Energy Lab

16. Load You Will Use

17. Assemble 1.Connect load to control Put flat spot (on LED) on right 2.Connect control to conductor 3.Connect conductor to second control 4.Connect second control to source

18. Test Turn on wind source (fan) Does light work?

19. Add a Load Connect conductors from one load to another Two teams work together Wire colors must match Connections made on same side of control

20. Test Turn on wind source (fan) Does light work? Is it dimmer?

21. Add a Source: Build a Wind Farm Connect conductors from one source to another Two teams still working together Wire colors must match Connections made on same side of control Wind Farm

22. Test Turn on wind source (fan) Does light work? Is it brighter?

23. Congratulations! You Have Successfully Built and Tested a Wind Farm

24. Cost to Build a Wind Farm in Your Classroom SOURCE: DC motor $5 - propeller $2 CONDUCTOR: Wire $5 for 100 feet CONTROL: Terminal strip $2 per unit LOAD: LED 25 cents per unit TOWER: PVC pipe, tees, elbows $5 OTHER SUPPLIES: Wood, screws, etc. $7 TOTAL COST - 2 turbines, 8 teams about $48
