That has left many communities worried that those now-idled places will simply be mothballed.</p></em><br /><br /><p>In an NPR segment, which aired in May, Jeff Brady discusses the Department of Community and Economic Development's plans to reuse and redevelop retired coal plants. Plans of action are listed in a "playbook" that outlines the attributes of listed coal plants and the pros and cons of each site. Through these assessments, it will help the Department realize what types of business would be an appropriate fit to relocate there. With the increased number of coal plants shutting down opportunities for coal cities will change for the better thanks to plans of introducing new businesses to the area by promoting these unused sites.&nbsp;</p> <p>Examples of the playbook in action are happening now in the small Pennsylvania town of Shamokin Dam. The coal-fired plant in town provided power for over six-decades before it was shut down in 2014.
