Passing a wind farm, I see some turbines spinning and others motionless. Why?

The Indianapolis Star quoted John Hall, assistant professor in the Department of Mechanical and Aerospace Engineering, in a story on why some wind turbines spin at wind farms while others do not.

Hall said some wind turbines may be stopped to match production with grid demand. “Basically, you have the utility company distributing power and buying and selling in real time,” Hall said. “Based on how much they need, wind farms would turn turbines off accordingly.”
