Hey Mr. Green,
Is there a practical electric car a person of moderate means can buy and operate? --Kent in Sherman Oaks, California
If by practical you mean an ordinary family car, I can't recommend anything except stealing one of those electric models--like Toyota's RAV4 EV--from the handful of lucky souls who acquired one before the auto industry quit making them. (That sad story was best told in the 2006 documentary by Chris Paine, Who Killed the Electric Car?)
Otherwise, you could order a Tesla Roadster for $100,000, but that might be a bit beyond your price range. You can explore a number of small, get-around-town models at the Electric Auto Association's Web site (eaaev.org/eaaevsforsale.html). The other option, if you are mechanically inclined and have a lot of time on your hands, is to retrofit a standard car with an electric motor at a cost of around $10,000, plus 200 to 300 hours of toil rigging it up. The EAA site can lead you to suppliers.
