The word "green" in the transport context has been tossed around quite a bit over the years and has garnered for itself a host of connotations, some of them negative. There are people who might conjure up images of unwashed hippies in a 30 year-old biodiesel rust bucket when they think of green car, but others might imagine smug-looking suburbanite Prius drivers.

Nowhere in the picture above do we see an easy place to charge an electric car, do we? The challenge of powering up plug-in vehicle in a densely populated urban environment is something that has been an issue in the EV scene for a while (and something we've covered a lot in the past), and it is most certainly a worthwhile topic for our Countdown to Earth Day series for new readers.

Driving in the dead of winter is harsh on a vehicle, and many of you have undoubtedly noticed that your fuel economy suffers as temps dip. In practice, gas mileage drops approximately 10 percent when temps go from cozy (60-80 degrees Fahrenheit) to bitter cold (less than 32 degrees Fahrenheit). But why does the weather affect the gas mileage of your vehicle?
They may not be dominating American roads (or any roads in the world, except for slot-car race tracks), but new electric vehicles are adding one more option to a growing list of potential "green" vehicles on every car buyer's shopping list. Like changing your incandescent light bulb for a compact fluorescent light bulb, the benefits of exchanging an inefficient gas guzzler for a high-mileage car really depend on what vehicle you're driving now, how many miles you drive per day and what your othe
