Trade your SUV for a Toyota Prius (Score 2, Informative)

The ultimate accessory for any motor-vehicle-needing Green Geek is a Toyota Prius.

The Prius is a SULEV (super-ultra low emission vehicle), which puts out about 90% less pollutants such as carbon monoxide (CO), nitrogen oxides (NOx) and hydrocarbons compared with a similarly-sized car, while using about 50% of the fuel and producing about 50% of the carbon dioxide.

These savings come from the use of a drivetrain incorporating an internal combustion engine, electric motor-generators and regenerative braking. You never plug in your Prius, and it has a range of 500 to 600 miles per tank. Needless to say, all of this technology is controlled by a number of computers, and there's a group dedicated to hacks and mods for the Prius.

For more information on this ideal Green Geek car, see this eight page PDF from the U.S. Department of Energy, or this site, which includes more information on the Prius than you probably want.
