* Note: Wind Energy Potential is from D.L. Elliott, L.L. Wendell, and G.L. Glower, An Assessment of the Available Windy Land Area and Wind Energy Potential in the Contiguous United States (Richland, WA: Pacific Northwest Laboratory, 1991). "Potential" is stated in terms of average Megawatts of Capacity (MWa), or megawatts of capacity at 100 percent capacity factor. 1 Mwa is roughly equal to 3 MW of nameplate wind turbine capacity.
