Utah is one of those western states with a high quality wind resource that has been commercially developed very slowly. A host of factors—both political and infrastructural—kept Utah with just 1 megawatt of wind power capacity until 2007. Today, Utah has 325 MW of wind capacity, thanks in large part to the addition of the Milford Wind project in the summer of 2011.
Check out this short but brilliant time-lapse video of the 97-tubine, 306-megawatt Milford Wind project. Other than the gratuitous brand-shot at the end, we really like this video.
