The advantages of natural gas conversion and greater use are obvious but bear repeating. Natural gas is a domestic source of energy and promises energy independence here in the U.S. Production, transport and building of infrastructure for natural gas would mean millions of new jobs. Natural gas prices are literally half that of competing oil and gasoline. Finally, carbon emissions for natural gas are about a third that for coal and other fossil fuels. What's not to like? But it seems both radical wings of each party continue to wield enormous influence. Neither candidate has made natural gas a cornerstone of a new and necessary energy policy. You would think in an election year at least one candidate would move to stake out this obvious position that would provide jobs, energy independence and greater environmental sensitivity. But maybe it's only obvious to the rest of us who are watching this campaign season unfold. This article was written by an independent contributor, separate from TheStreet's regular news coverage.
