Is wind energy the right choice for your farm or ranch?... Wind Energy Calculator TheWind Energy Calculator was developed to assist farm and ranch owners in evaluating the economics of installing a wind turbine on their property to provide electricity for farm and home use. To use the program, download the spreadsheet to your computer. Then enter specific information about the type of turbine you are considering, the estimated annual average wind speed, information about electricity use and electric rates, and information about financing and income taxes. The program will then estimate the cash flows for investing in a wind turbine and the rate of return on the cash investments. Windustry has provided this Excel spreadsheet which uses macros.
