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.

Recharge Wrap-up: Eigg's renewable energy grid, Wulin City Car EV looks like i3

Scotland's Isle of Eigg's electrical grid relies solely on wind, hydro and solar power. It's the first grid of its kind after switching to renewable energy from noisy, unreliable diesel generators. Scotland's renewable resources are fodder for supporters of independence form the UK, and Eigg is a perfect example of that potential. Besides being a responsible community, it also seems like a lovely place to visit. Read more at Reuters. London Mayor Boris Johnson is calling for incentives for diesel vehicle scrapping. The goal is to improve London's air quality, encourage the purchase of clean vehicles and offset the inconvenience of charging diesel cars to enter the city's proposed Ultra Low Emissions Zone.

As part of the Trans-European Transport Network (T-ENT) program, the group aims to create extended EV-friendly roadways with the UK Rapid Charge Network, connecting major cities on the islands. Plans for the network include 70 rapid chargers along 684 miles of road. The four manufacturers also want to extend the project to mainland Europe to encourage the adoption of EVs.

The City Car EV concept is slated to make its debut in November at the Guangzhou Auto Show, while a production version could make its way onto Chinese roads next year. We might have to wait until the debut to know what powers the City Car, as those details haven't been released yet. General Motors is a 43-percent stakeholder in Wuling.

Now customers will be able to use either app to pay in any of the city's 20,000 green and yellow taxis. There's no need for separate apps for separate cabs, and no need for drivers to install any new equipment. The groups behind the apps hope to expand this functionality to other cities across the country. Read more in the press release below.

Nissan unveils Altima-based V8 Supercars [w/videos]

Good as it is, when we think about the Nissan Altima, the words "V8" or "supercar" are not in our vernacular, but Nissan Motorsports is looking to change all that. After unveiling the race version of its Altima sedan intended for the Australian V8 Supercars series back in October, the four race teams and their cars were revealed yesterday ahead of a preseason test session this weekend.
Two of the Altima racecars will be sponsored by Jack Daniels while the other two will wear Norton (as in Norton Anti-Virus) black-and-yellow livery. The season officially kicks off on March 1, and we'll get to see the V8-powered Altima on US soil from May 17-19 when the V8 Supercars series hits the new Circuit of the Americas in Austin. Scroll down to watch a couple videos and a press release issued for the team introductions.
