Coal is not just for burning. Coal gassification and syngas-to-liquid conversion to produce clean diesel fuel is one of the technologies that csn put coal to a good use.
I don't see how the author of the article can make the case that access to affordable energy is a national security issue, while at the same time suggesting that exporting such energy is a critical U.S. interest.
Is energy a national security asset, or not? If it is, then what do we accomplish when we promote an energy export policy that not only gives this energy to foreign countries, but drives up the cost of that energy here at home?
Yes. But right now, with climate change and greenhouse gasses as a main concern, LNG is perhaps the most strategic fuel in the coming years. It is clean burning with a low impact on the environment and therefore regarded highly desirable by many countries.
