Natural gas has similar range limitations to electric cars, and the infrastructure is almost nonexistent. Even with fracking, our domestic supplies might last only 60-70 years? And there are myriad of problems with fracking -- lots of methane (natural gas) is released from the ground, and it is a 20X worse GHG than carbon dioxide. Wells are poisoned, and why is it that the gas drilling industry needs to keep the chemicals in the fracking fluid secret?
Now, if we start getting our methane from renewable sources -- which is very doable, then fine. Methane digesters can make gas from plant and animal waste (including our waste). This reuses carbon that has recently come from the atmosphere, so it adds nothing.
