As heard on

Listen to this story:

Natural gas is a great alternative fuel. It burns very cleanly and there’s lots of it, so how come we don’t use it in our cars?

It wasn’t all that long ago that GM, Ford and Chrysler all sold vehicles that could run on natural gas. Today, only Honda sells them.

Even though many states offered very generous credits to anyone who bought a natural gas vehicle, they just never caught on. That’s partly due to infrastructure. Even though you can buy natural gas in a lot of places, it isn’t on every street corner. And the gas tank takes up a lot of room in a vehicle. And there’s also a fear of a big explosion at liquid natural gas port facilities.

So put it all together, and the environmentalists say we should use natural gas to generate electricity and then put that in the batteries of plug-in hybrids, rather than burning it in our engines.
