Summary: In the remote village of Ambler, Alaska, temperatures can fall to minus 60 degrees Fahrenheit in the winter, so heating the community is a big job. This past September, Ambler switched to a renewable energy option in an effort to go greener -- a change that also means a path toward a more sustainable economy for Alaska Native communities.
