This map displays that Oregon has wind resources consistent with utility-scale production. The good-to-excellent supply areas are concentrated on ridge crests throughout the map. The most significant non-ridge crest areas with at least good supply are positioned at Vansycle ridge in northeastern Oregon, the area south of the Columbia River east of the Dalles, and southeast of La Grande.

A renewable resource, wind is organized by wind power classes, these are derived from usual wind speeds. The classes span from Class 1 (the slowest) to Class 7 (the peak). On the whole, at 150 feet , wind speed Class 4 or higher can be practical for making wind power with large turbines. Class 4 and higher are considered high-quality energy supplies. Specific areas in the Class 3 regions might have superior wind power classes at 80 meters than shown on the 50 meter map due to possible elevated wind shear. Given the improvements in machinery, some zones in the Class 3 locations may proper for large scale wind power development.
