Is methane a good fuel for cars?

    In compressed natural gas (CNG), methane makes a very good fuel for cars.  It has an efficiency not far below gasoline, has lower emissions, and is cheap.  It is not a solution to our problems, however, since natural gas is a fossil fuel and, although the quantities are lower, it does still emit greenhouse gases.  It also requires a much larger tank than gasoline to afford the car a comparable range, sacrificing, for example, the trunk space for a CNG tank.  Methane can also be extracted from organic waste to create biogas.
