Impact of wind energy on reduction of air pollution due to particulate matter

I found this interesting chart in http://www.aweablog.org/national-lab-report-wind-energy-win-win-win-for-consumers-environment-and-economy/

It quantifies the health and economic savings from reduced air pollution in all regions of the country--it is a conservative estimate of the cost of air pollution and only focuses on savings from renewable energy’s reduction of one air pollutant: particulate matter.
