This paper is a review of wind energy articles that use geographic information systems (GIS). It is the hope of the authors that the article will inform renewable energy researchers of the potential for using GIS in their work, and geographers and spatial scientists to learn about the opportunities in wind turbine research. GIS can be used for wind energy planning to determine whether there is adequate wind energy at a site as well as whether the landscape and land-uses are appropriate for wind turbine developments. These types of GIS applications have been used worldwide, typically using previously collected data. To determine which sites are preferable, variables of interest are treated as distinct layers in GIS, and areas that are unsuitable for wind turbine development become evident. Areas that are not preferred for wind turbines are environmentally protected areas or landscapes that cannot be developed effectively. GIS is the ideal tool for identifying preferred sites for wind farms, especially when using decision support systems. Future decision support system research in GIS should consider on-site conditions as well as the opinion of stakeholders and local residents. Involving stakeholders in the decision-making process, either through increased communication or visualization activities that use GIS can lead to higher acceptance of wind turbine installations. Examining the failures and successes of other wind turbine installations may be informative for future developments
