Plug-In Hybrids are not yet available, but new research says that when they are their use could slash emissions by, well… a lot. Theoretically, plug-in hybrids could be driven up to 40 miles a day on electricity alone. More good news: using electricity for fuel wouldn’t harm the power grid and the equivalent cost would be about $1 a gallon. But can car manufacturers make the cars cheap enough and the electric company make power clean enough to sell the idea to the American public?
The upbeat news for plug-ins, seen by many as the next big step in environmentally friendly automotive technology, came with two caveats. Achieving the maximum air quality improvements would require a significant cut in the pollution produced by electric utilities. It’s also dependent on large-scale adoption of plug-in hybrids, which may not be in new-car showrooms for several years.
