Wind Power and Land Use

Quick factoid: for wind power to provide 20% of U.S. electricity, roughly 33,000 square miles of land would be required. This is an amount of land equal to approximately one-third of Colorado, one-third of Wyoming, or one-fifth of Montana. Further, 95% to 98% of that 33,000 square miles would continue to be available for farming or ranching--the actual footprint of the wind turbines and supporting equipment (including service roads) is 2% to 5% of the land within a wind farm's boundary. Conclusion: availability of land, in gross terms, is not a constraint to onshore development of large amounts of wind power in the U.S.
