The “war on coal” is a catchphrase typically used by industry-backers to rally against the Obama administration, but in his new book, "Coal Wars," author Richard Martin, comes at the issue from the other side. In addition to being an author, Martin works for Navigant Research, one of the world’s leading clean energy consulting firms, and as he explained in an interview with Wyoming Public Radio’s Stephanie Joyce, while he sees coal’s decline as inevitable, the book is his attempt to understand what that means for people in coal country.
