Filling Up on Natural Gas

Not only does burning natural gas only emit CO2 and water vapor, it emits less CO2 than most other energy sources, including ethanol. Good for the environment, and Kyoto countries. Unfortunately for your price analysis, it's not as scarce as other fuel sources because it can be obtained in various ways. Natural gas is mostly methane. Where else does methane come from other than the ground? I'll give you a hint, look up anaerobic digestion.
