A method for determining a location of a conversion device for converting wind energy into electrical energy comprises establishing a plurality of data layers, including at least a wind data layer and a transmission grid data layer. Each data layer contains attribute data that is associated with corresponding location data. The location data of one layer is aligned with the location data of other layers to form a composite layer. The composite layer is searched to identify the first compliant location data associated with a target value or a target value range of the attribute data for the wind data layer. The composite layer is searched to identify a second compliant location data associated with a target value or a target value range of the attribute data for the transmission grid data. The composite layer is searched to identify a third compliant location data associated with a target value or target value range of the attribute data for an additional data layer other than the wind data layer and the transmission grid data layer. The intersection of the first compliant location data, the second compliant location data, and the third compliant data is determined. The intersection is identified as one or more preferential regions for locating an energy conversion device.
