Plug in Hybrid cars are Among the Greenest
The greenest car is a plug-in hybrid . It allows electric-only driving for almost all your day to day driving (while you can use the gas engine for long trips, avoiding the still-immature, sometimes-not-working national recharging system). And its batteries are much smaller than those in all-electric cars, which scores much better in the "let's not destroy the Earth too much" test. Someday we'll have greener (and safer) car batteries, but for now PHEV may be a smart choice.
