Overall, wind farms cost in the area of $1,000 per kW of capacity, so a wind farm consisting of seven 1.8-MW turbines runs about $12.6 million.
As a wind turbine will generally bring in a lease value of $5000 - $8000 per year to the owner of the land, and as that is higher than most crops will yield per acre per year, it's an excellent additional revenue stream, especially for the multi-revenue stream, small-business owners we call farmers.t is not the fault of the system, but average winds. Wind Turbines are rated at between 25 and 28 MPH winds. If the wind goes over 31 MPH, most systems shut down. Power is cubed, so a wind of 14 MPH provides 100KWH from a 1 MWH system.
