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.

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.
