Pike: 17 million natural gas vehicles by 2015

A new report by Pike Research claims that more than 17 million natural gas vehicles will be on the roads of the world by 2015.

Will the US get in the natural gas vehicle game? Or is the battery the only way forward for US policy?

More important, since natural gas vehicles can also be hybrid vehicles, or even plug-in hybrid vehicles, why not take natural gas more seriously since it is cleaner than petroleum and it can come from domestic sources?
