1 NREL previously calculated wind farm land usage at about 85 acres per MW of capacity and capacity density of 3.0 Â±1.7 MW/km 2. 2  Yale calculated wind energy usage down to the turbine level, calculating 1-3 acres per turbine.
The range is from 100,000 to 300,000 seeds per acre. A major seed company recently recommended planting 200,000 to 230,000 seeds per acre. Research at Iowa State University has shown that a lower seeding rate will give top yields.
