Abstract Background The development of wind energy in western Oklahoma has expanded dramatically in recent years, as the amount of installed capacity has gone from 0 in 2002 to enough turbines to generate approximately 20% of Oklahoma’s electrical needs in 2016. Associated with that development has been an increase in tax revenue and support for local schools, including many in struggling areas. This paper examines and quantifies the overall impact of the increased wind-industry related tax revenue in western Oklahoma. Methods Variables collected and analyzed for this study include: percentage of revenue from local and county sources, student-teacher ratios, and per-student expenditures. This information was obtained for each school district from 1997 to 2015. The data then mapped and analyzed using both statistical and inferential analysis. T tests and Mann Whitney U tests were utilized identify statistically meaningful differences between school districts with and without wind turbines. In addition, a longitudinal temporal analysis was undertaken for selected locations to further illustrate the impact of the wind farms on the region. Results The spatial patterns of local school revenue and related variables have been analyzed and compared to available socioeconomic and demographic information. Spatial and multivariate analysis has been undertaken to highlight differences in characteristics of public school districts with and without wind turbines. Results show significant differences in revenue from local and county sources between school districts with and without wind farms. However, school districts with wind farms did not have higher per-student expenditures or lower student-teacher ratios than surrounding districts. The significant change in percentage of revenue from local and county sources illustrates the relative importance of the industry, especially during challenging economic times and particularly in those areas with fewer other revenue sources. Conclusions Though school districts with wind farms did not differ from surrounding districts in terms of per-student expenditures or student-teacher ratios, the significant difference in revenue from local and county sources suggests these districts may be less susceptible to changes in funding from state and federal sources.
