Even with the occasional blow-out I feel that piped NG is a much cleaner alternative to the coal generating plants operating now, or under construction or consideration in some jurisdictions. If inexpensive, unfracked, uncompressed NG, became widely available, the economic incentives for coal generation would disappear.
Wind, hydro and solar are the future, but eliminating coal, fracked NG, LNG and possibly nuclear should all bring us closer to our goals.
I assume that a coal plant could be converted to a NG facility fairly easily. The result wouldn't be perfect, but it would be much better than continuing to burn coal. Once coal is eliminated we could begin working our way down the list.

BTW - I fear for Ontario's coal free generation now that Ford has been elected. If we backslide others will follow and we probably will have lost whatever small hope we had for our grandchildren's future.
