• If you’ve been looking east this morning you may have noticed that Carleton’s wind turbine blades haven’t been doing much turning.  While we’d like it to be cranking out clean power the reason for the temporary shut down is impressive indeed.  Northfield, in the midst of an uncharacteristic several day long warm front, has also been experiencing some rather blustery winds, above 40 mph at turbine hub height.  These gusts have most likely knocked some sensors off balance.

  • Minnesota’s weather often seems to me the creation of a disgruntled, vindictive child.  Take, for example, the average wind speeds in the months of December and January.  At the time when temperatures begin to really dip, southern Minnesota often experiences some of its highest average wind speeds of the year, so that an otherwise reasonable 5 or 10 degrees F can go to 10 or 15 below in a heartbeat.  But while it’s bad news for my face, all that wind is great news for wind turbines.
