Massachusetts has wind resources suitable with utility-scale wind farms. Excellent-to-outstanding supply is located on the northern portion of Cape Cod and good and very good areas are found in the southern portion of Cape Cod and along the shore of Martha's Vineyard and Nantucket. Particular ridge crest areas of the Berkshires in western Massachusetts also have exceptional wind resource.

A renewable energy source, wind is organized by wind power classes, these are made from normal airstream speeds. These classes vary from Class 1 (the slowest) to Class 7 (the top). On the whole, at 150 feet , wind power Class 4 or higher can be practical for making wind power with big turbines. Class 4 and above are considered good energy supplies. Particular areas in the Class 3 regions can have higher wind power class values at 80 meters than exposed on the 50 meter map because of possible high wind shear. As a result of the advances in machinery, many regions in the Class 3 locations may appropriate for large scale wind power development.
