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

Illinois Ranks High in Wind Energy Development

• 4th in existing wind power capacity• 14th in wind potential

Sources: American Wind Energy Association and National Renewable Energy Laboratory

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

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

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

Load You Will Use

Assemble

1. Connect load to control• Put flat spot (on LED) on

right2. Connect control to conductor3. Connect conductor to second

control4. Connect second control to

source

Test

Turn on wind source (fan)

Does light work?

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

Test

Turn on wind source (fan)

Does light work?

Is it dimmer?

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

Test

Turn on wind source (fan)

Does light work?

Is it brighter?

Congratulations!
