How Does 100 MPG Sound?
Politicians and environmentalists talk a good game about lessening U.S. dependence on foreign oil and reducing greenhouse gas emissions that contribute to global warming. Usually absent from the game plan, though, are practical, workable solutions that aren't a decade or more away.

General Motors, the kingpin of a U.S. auto industry that's been left in the competitive dust by Japan in fuel efficiency, was the buzz of last week's North American International Auto Show as it previewed its plug-in hybrid electric Chevrolet Volt. Plug-in hybrid electric vehicles (PHEVs) offer commuters unheard-of fuel savings - in some cases, they could run hundreds of miles on a gallon of gasoline or other, cleaner liquid fuel like biodiesel. And, according to GM, they could be in showrooms within three to five years. If government incentives hasten their development, PHEVs could be coming off assembly lines even sooner.
