He adds: "in theory, you could have a plug-in hybrid with a renewable fuel powered [internal combustion engine] and eliminate the need for petroleum all together."

他还称：“理论上讲，你可以在使用可再生燃料的引擎上增加一个混合插件，这样可以彻底不使用汽油。”

However, there is evidence to suggest that particulate emissions from fossil-fuel powered vehicles and traffic are more toxic than a general mixture of pollutants.

但有证据表明机动车尾气中散发的颗粒物比一般污染物的混合体更具毒性。

To get this generation, many states now require fossil fuel powered generators to buy "green tags" from, for instance, solar generators, for every unit of power sold by that fossil plant.

When life-cycle costs are compared, natural gas is currently a more economical decision than flex-fuel powered vehicles, although both are more expensive than gasoline at current figures (keep in mind that these dynamics could change due to oil shocks or increased demand for traditional fuels both real risks).

So having cheap electricity should mean that a place is less likely, not more, to get a fuel cell powered system.
