This thesis is an interdisciplinary study of the potential of offshore wind farms in the western Great Lakes. It includes an opinion survey of representatives of the public, an analysis of potential offshore sites, an estimate of the potential power and energy available, an extensive review of existing European experience, and the discovery of locally relevant information. The opinion survey found that there was a marked preference among respondents in counties bordering the lakes for onshore wind farms over offshore ones. Opposition to offshore projects is stronger along Lake Superior than Lake Michigan. A map analysis identifies several suitable sites along Lake Superior and many sites along Lake Michigan. The potential electric power of wind farms offshore in the study area with constraints applied is estimated to be approximately 9,700 MW. Available information indicates that most environmental impacts would likely be minimal in this area, with the possible exception of perceived view shed impacts.
