Shutting Off Wind Turbines
If you drive by a wind farm and see many wind turbines spinning, it is also common to find a few wind turbines not spinning, having been intentionally turned off by the engineers in order to manage a consistent energy grid.

Near Westside, IA
Driving Question
- Why do these wind turbines get turned off?
Probing Questions
- How do these turbines get turned off? Why can’t they just be unplugged?
- How can the amount of time these are turned off be minimized?
- How does a wind turbine work?
Classroom Suggestions
Students could:
- Investigate why the energy companies need to “turn off” these turbines on windy days.
- Outline how the electric grid needs to match the amount of energy being used.
- Research why it's important for utility companies keep the electric grid consistent.
- Develop their own strategy for storing wind energy into another form of energy ready to be used when there is not any wind in the area.
