First, Carleton College built a wind turbine on a field not far from its Northfield campus.Then St. Olaf College, the school's rival across town, countered with its own.
Now, Carleton wants to put up a second turbine.
Northfield has become, perhaps, Minnesota's Home of the Collegiate Wind Turbine, fueling student pride as well as a bit of friendly rivalry.
"To be honest, I don't really understand it," said Carleton grad Chris Erickson. But when St. Olaf's turbine went up in 2006, two years after its twin, some of his classmates said "St. Olaf is just copying Carleton."
The new turbine would stand near Carleton's recreation center. It could start spinning as early as October if plans go forward, but factors such as obtaining permits could push that back to 2010, the college said.
It's not a competition, said Erickson and others at both schools. The colleges share an interest in renewable energy, and they've traded ideas about the turbines. But with two colleges in town, it's a safe bet that students spend a fair amount of time comparing sports teams, school rankings -- and wind turbines.
One point of debate: St. Olaf's turbine looks taller because it stands near campus buildings instead of in a field. "Early on, we heard rumors that Carleton students thought we put up a bigger one to show them up, but the truth is they're the same model," said Pete Sandberg, St. Olaf's assistant vice president for facilities. "It would be fairly easy to perceive that ours might be bigger, but they're the same."
The first two turbines are indeed the same height -- 370 feet. But there is one major difference: The electricity from St. Olaf's flows directly into college buildings, while Carleton sells its wind power to Xcel Energy.
