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.

Autoblog Podcast #327:

President Obama will be on Comedians in Cars Getting Coffee

The seventh season of Jerry Seinfeld's excellent Comedians In Cars Getting Coffee will debut on Wednesday, December 30, and if this first trailer is any indication, the guest lineup is damn impressive. But rather than building up to one big guest over the course of the season, the show is starting with one of the biggest guests possible – the president of the United States. President Barack Obama will join Seinfeld behind the wheel of what looks like a 1963 Chevrolet Corvette Stingray for a trip around the South Lawn of the White House. According to CBS, the pair will enjoy their coffee in the staff dining room, which is probably a better idea than crippling Washington, D.C., with a Stingray-led motorcade. Aside from the president, Seinfeld has recruited a couple comedy icons, including first-timers Will Ferrell and Steve Martin. Also appearing are Garry Shandling, Sebastian Maniscalco, and Kathleen Madigan. The four-wheeled stars will include the Corvette, a Plymouth Superbird, a Chevy Camaro, a classic Porsche 911, a BMW 2002, and what we think is a (rather troublesome) 1952 Siata 208 8V Coupe Balbo. You can check out the entire trailer up at the top of the page.
