This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

2014 Nissan Versa Note

Incredible Value Has Trouble Winning Hearts
How important is vehicle sticker price? How imperative is fuel economy? What about passenger room and technology?
Nissan is hoping that consumers find all four objective measurements significant, because the all-new 2014 Versa Note excels in each of those areas. Not only does the five-door deliver the most competitive pricing, but it provides best-in-class combined fuel economy and best-in-class total interior volume. And the new model offers a full range of innovative technology, including available navigation and the automaker's impressive Around-View monitor to ease parking.

Should you buy an EV?

Gas prices are hitting the skids and EVs are following suit; nearly every model in today's market has experienced a double-digit decline in sales – with the always notable exception of the Tesla Model S. Some EVs are in the last year of their generation while others have been half-heartedly designed and engineered to fulfill federal government quotas. The two non-Tesla front runners, the Chevy Volt and Nissan Leaf, are in the unfortunate position of offering customers "2015" vehicles that were designed with 2011 in mind. Yet there's plenty of love in the air. Nissan has built over 180,000 Leafs worldwide, and chances are you will be seeing a second electric vehicle accompanying the Leaf when the new generation is released in the coming months. The Chevy Volt now offers the highest customer satisfaction out of any car or truck sold in North America. Forget the luxury cars, the sports cars, the family trucksters, and even the rolling flagship that guides Tesla's jaw dropping valuation on Wall Street. You want happy with your EV? The brand that's rocking the segment right now is Chevy. It's been doing so for a while. The EV market is poised to become a lot more sophisticated over the next 18 months with the three leading manufacturers – Tesla, General Motors, and Nissan – launching five brand new models along with no fewer than 16 other manufacturers making many of their bread and butter cars available as plug-in hybrids. So, if you want to keep your money as far away from the Arab dictatorships and Russian mafia as Mercury is from Pluto, and enjoy your commute, we're more than ready to do our part! So let's begin with the most important question. What's Your Range? How much driving do you generally do in a day? If the answer to that question is 50 miles or fewer, an all-electric vehicle like the Nissan Leaf may be the best ingredient for your driving recipe. This is especially true if you have a second vehicle you can use for the occasional longer drive or are willing to rent for the weekend. But here's a little surprise for you. The upcoming Chevy Volt was designed to be driven in all-electric mode for over 50 miles. Fifty-three, to be exact. Plus, the Volt's battery has experienced a lot fewer deterioration issues than the Nissan Leaf's due in part to the Volt's liquid-cooled battery, which also uses a lot less of its capacity than the air-cooled Leaf's does.
