This map shows the highest wind supply in Connecticut are found on the ridge crests in the northwestern section of the map. There are some Class 3 areas on the southern shoreline along Long Island Sound.

As a renewable resource, wind is categorized according to wind power classes, these are derived from normal wind speeds. These classes span from Class 1 (the slowest) to Class 7 (the top). Ordinarily, at 50 meters , windpower Class 4 or higher can be functional for producing wind energy with big turbines. Class 4 and above are deemed good energy supplies. Special areas in the Class 3 areas could have greater wind power classes at 80 meters than exposed on the 50 meter map as a result of potential elevated wind shear. Given the advances in technologies, some zones in the Class 3 areas may correct for large scale wind power development.
