A logical evolution as an industry ‘matures’.   The Wyoming legislature has just passed a $1 per Megawatt generation tax on windfarms in existence for 3 years or more.  With double depreciation and federal subsidies for implementation completing, it’s logical to apply this measure as that state  does on energy sources such as coal, natural gas, and oil production.   Since it was proposed by the governor, it will likely be signed.  The Department of Energy’s Energy Information Agency estimated in 2008 that wind receives $23.37 in federal subsidies per megawatt hour.  So Wyoming is only asking for 4.3% of what is given to the operators by every US taxpayer.  Let windpower stand on its own feet.
