Numbers claims in Wisconsin are puffed up, says the MacIver Institute:

Although they are touted and promoted by policy makers and opinion leaders across the state, accurately defining and keeping track of ‘green jobs’ has proven nearly impossible in Wisconsin. … In all, at the time of our search, the [Wisconsin Wind Works] database claimed 7,632 jobs among the eight manufacturers that were current primary suppliers to the wind industry. Yet, the MacIver News Service was only able to identify 31 jobs at those companies which were specifically tied to wind energy related products.
