In this segment of the The Motley Fool's "Ask a Fool" series, we take a question from a Foolish reader who asks, "What are your thoughts on Coal? Is it a good investment?" Energy analysts Joel South and Taylor Muckerman look into the global coal industry and discuss areas to stay away from and also a few developments investors need to watch to gauge the long-term viability of the coking coal industry.    

This segment is from Thursday's edition of "Digging for Value," in which sector analysts Joel South and Taylor Muckerman discuss energy and materials news with host Alison Southwick. The twice-weekly show can be viewed on Tuesdays and Thursdays. It can also be found on Twitter, along with our extended coverage of the energy and materials sectors @TMFEnergy.
