I took this screen shot about ten years ago. Both computers and the internet have advanced nicely.
We're still not there with electric cars. (Double-click on the image to see it larger.) It just continues to cost more energy to produce electricity and pump it out to your house or a charging station compared to simple gasoline (petrol) or diesel (better yet, energy-wise). Cleaner? Well, the pollution just gets moved from the tailpipe to the power-generation plant, which is coal-powered (dirty), in much of America, anyhow. If the power comes from hydroelectricity or wind power, an electric car can be cleaner.
Hybrids? That's a different story. Energy recovery through regenerative braking is a great thing. (When I grow up, maybe I'll get a Prius.)
By the way, there is a nice little article in Wikipedia on the car featured here.
