Natural Gas - The All-American Clean Fuel
The key to producing less carbon dioxide emissions from fossil fuels is to use the fuel with the lowest carbon to hydrogen ratio. Coal is the least desirable because there are roughly 2 carbons for each hydrogen; oil is cleaner because it has the inverse ratio of approximately one carbon for 2 hydrogen molecules; and best of all is methane (CH4), with 4 hydrogen molecules for each carbon molecule. Although natural gas is primarily methane, it does contain, some longer chain hydrocarbons such as ethane, propane, butane, pentane etc. that make it slightly less desirable than pure methane. Thus, the reduction in carbon dioxide emissions when natural gas is substituted for gasoline in an automobile is about 25-30%.
