Two small towns look at ways to move beyond their reliance on coal. One year ago, the small town of Nucla, Colorado, learned that its coal-fired power plant would shut down, taking with it 55 jobs at the plant and another 28 jobs in the New Horizon coal mine, which fuels the plant. For some communities, the loss of 83 jobs might be a bump …
