Known as "Britain's Greenest Car," the G-Wiz, made by Indian electric vehicle company REVA, is the kind of product that sells itself. With no engine or exhaust, the car boasts zero emissions. It's even carbon neutral, thanks to manufacturing and shipping costs that have been vigilantly "carbon balanced" by its manufacturers. The little green machine, which comes in a wide array of colors, can reach a top speed of 50 mph and ranges up to 48 miles per charge. Its safety package has been independently tested, and perhaps best of all is the exceptionally reasonable price. G-Wiz are bought online, which keeps the price low, and customers are assured they'll recoup the purchase and running costs in a year. Sorry, retailer GoingGreen doesn't sell G-Wiz outside the UK, but REVA is test marketing the car in the United States, Norway, Spain and other European countries.

A great option for those seeking a gas-free, sweat-free commute to school or work, the fully equipped eGO Cycle 2 SE will get you there in style. With a sleek look and amenities such as directional signals, left grip lighting, horn controls, and spoke alloy mag wheels, this user-friendly motorized bike also enjoys notable battery life, distance range, speed, and ergonomics. Some U.S. states regard the eGo as a moped and require a special license and registration, so inquire about your local regulations before taking that first ride. In Europe, where it's called the Helio, the cycle is Vehicle Type Approved as a moped and may be used on public roads in all EU member countries.
