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: Ford HQ gets giant solar array, Chevy City Express gets 24 MPG city

Ford will be building Michigan's largest solar array at its Dearborn headquarters. With funding from DTE Energy, the solar carport will provide covered parking, as well 30 charging stations for electric vehicles. The array is expected to generate 1.13 million kWh per year for Ford's operations, and offset 794 metric tons of carbon emissions. Read more in the press release below. Chevrolet announced the fuel economy for the 2015 City Express, at 25 mpg combined. The cargo van is rated at 24 mpg in the city, and 26 mpg on the highway. Chevy credits the van's inline four-cylinder engine and continuously variable transmission for its impressive city mileage. For its customers - which are mainly businesses - "The fuel economy of the City Express will help stretch their dollar at the pump and give them the flexibility to invest the savings back into their business," says Chevrolet's Ed Peper. The City Express starts at $22,950. Read more in the press release below. Engineers at the University of Wisconsin have developed an efficient engine that runs on a diesel-gas blend. The engine, which uses a computer to control the blend proportions, is about 15 percent more efficient than the any diesel engine according to mechanical engineering professor Rolf Reitz. The team has put the experimental reactivity controlled compression ignition (RCCI) engine in a demonstration car - a 2009 Saturn. "This vehicle can do 50 miles per gallon," says Reitz, who believes the system could be improved further. Read more at Wisconsin Public Radio. The Southeast Alternative Fuel Conference and Expo will take place in October in Raleigh, North Carolina. Held at the NC Clean Energy Technology Center from October 22-24, the event will feature a variety of exhibitors, speakers and, most importantly, alternatively powered vehicles. "The three day conference will be a one-stop shop for fleet and transportation related decision makers to learn about return on investment, efficiency and alternative transportation fuels such as biodiesel, electricity, ethanol, propane and natural gas," says Anne Tazewell of the NC Clean Energy Technology Center. If you can't make it to Raleigh for the Expo, you can still enter to win a free two-year lease of a Nissan Leaf at the Center's website. Learn more about the event in the press release, below.

Former Fisker CEO has some advice for Tesla Motors

Former Fisker Automotive CEO and ex-Chevrolet Volt vehicle-line director Tony Posawatz has some words of caution for Tesla Motors. The long-time automaker executive questions the California automaker's long-term viability – and gives some praise – in a talk with Benzinga, which you can listen to below. While the all-wheel-drive D that Tesla unveiled earlier this month in Southern California wowed a packed crowd, Posawatz (starting at around minute 4:45 in the interview) says Tesla would've been better off taking the resources it expended toward that Model S upgrade and directed them towards speeding up the development of a more affordable plug-in. Perhaps a number of investors agreed, since the company's stock fell the day after the D was announced. Posawatz says Tesla has been over-reliant on the sale of ZEV credits. Posawatz also says that Tesla has been over-reliant on the sale of zero-emissions vehicle credits in California for its earnings and questions whether the automaker will ever work at a large enough scale to sufficiently drive down costs and make consistent profits. Tesla CEO Elon Musk would take issue with this characterization. Posawatz first made his mark in the plug-in vehicle world when he was the vehicle-line director at General Motors for the Volt extended-range plug-in from 2006 to 2012. Later that year, he joined extended-range plug-in maker Fisker Automotive as its CEO, though quit that job during the summer of 2013 as the company was descending into insolvency. He joined the Electrification Coalition this past March. News Source: Benzinga Green Chevrolet Fisker Tesla Electric PHEV Tony Posawatz
