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.

Carlos Ghosn to step down as Nissan CEO on April 1

Carlos Ghosn announced he will be stepping down as CEO of the Nissan on April 1, to be replaced by current Nissan co-CEO Hiroto Saikawa. The move comes after close to two decades of leadership and the rebuilding of a company that was close to disaster. Ghosn isn't finished with the company he helped rebuild, as he will remain on as chairman of the board and continue on as leader of the Renault-Nissan Alliance following the change of guard. In addition to running Renault-Nissan, Ghosn has taken over as chairman of Mitsubishi Motors after acquiring a 34-percent stake in 2016, a move he spearheaded. Ghosn stated, "I am confident that the management team I have developed at Nissan over the past 18 years has the talent and experience to meet the company's operational and strategic goals. Having recently taken on new responsibilities at Mitsubishi Motors, and taking into consideration the upcoming Nissan general shareholders meeting, I have decided that the time is right for Hiroto Saikawa to succeed me as Nissan's CEO." A release from Renault-Nissan said the move allows Ghosn to focus more attention on bringing together the three companies. Saikawa, his replacement, has been with Nissan since 1977 and has overseen operations in the company's markets worldwide.

Recharge Wrap-up: Tesla will sell Model S on Alibaba in China, Wrightspeed electrifies garbage trucks

Tesla will sell cars in China using Alibaba's Tmall website. Customers will be able to use the Chinese shopping site to place an $8,200 deposit toward a Model S. Tmall will feature 18 preconfigured versions for customers to choose from, which won't offer quite the level of customization as Tesla's US site. Bloomberg's Jamie Butters calls it a "defensive move" on Tesla's part, and still expects the company to sell cars in China the traditional way. Watch the video at Bloomberg or read more at Bidness Etc. Tesla co-founder Ian Wright's company Wrightspeed is converting garbage trucks to EVs. The same brand that created the exciting X1 EV is making trash collection much cleaner. "Garbage trucks are the perfect driving cycle for us: they get two or three miles per gallon, drive 130 miles a day with 1,000 hard stops that chew on the brakes," says Wright. The system puts an electric motor at each of the truck's drive wheels, and includes an on-board generator that runs on diesel or natural gas to extend driving range. Read more at Xconomy. British company Hillside Leisure is converting the Nissan e-NV200 into a camper van. The electric RV, called the DalburyE, debuted at the UK's Motorhome and Caravan Show in Birmingham. It sleeps up to four people, and features a pop-up roof, a gas stove, fridge, sink and other amenities. It's a great way to take full advantage of an RV park's electrical outlet to charge the van while camping in it. Read more at Transport Evolved, and see more photos at Hillside Liesure's blog.
