The local government and a few nosy neighbors have been disputing the construction of this turbine for over 4 years, since it was built in 2010.
Jay Nygard actually owns a company called Go Green Energy, which sells wind turbines in other areas of Minnesota, but he isn't able to do so in Orono where he lives because of permit and licensing laws. These are the same laws that are preventing Nygard from building on his own property.
In recent years there have been at least 8 lawsuits back and forth between Nygard, the local government and his neighbors. The neighbors claim that his windmills are an eyesore and a nuisance, but in reality it isn't actually any of their business.
Nygard has the right to do whatever he wants with his own property, but unfortunately in a democracy such as the United States, the property rights of an individual can be overridden according to the whims of politicians and the demands of uninvolved third parties.
