> The density of wind turbines per unit of land area depends on many factors. Wind farms containing very large (1.5–2 megaWatt) turbines may have only one for every 25–50 acres. Smaller turbines can be more closely spaced.

> At either rate, the overall harvestable wind energy per unit of land at fully rated conditions (approx. 12 meters/sec wind speed), is generally in the range of 50 to 100 kW per acre.

  harvestable_wind_energy = 50-100 kW/acre

How much less $ does an acre storing the maximum number of wind turbines yield compared to a wind turbine on, say, 50 acres?
