Dear EarthTalk: If you have an electric or plug-in hybrid car, you're paying for electricity rather than gasoline all or most of the time. How does that cost compare to a gas-powered car's cost-per-mile? And since the electricity may be generated from some other polluting source, does it really work out to be better for the environment?
