NASCAR has hit a milestone of 7 million miles using E15 gasoline. The stock car race series began using the ethanol blend - in particular, Sunoco Green E15, using American-made ethanol - in 2011. NASCAR says it has proven the viability and performance of the fuel in the demanding stings of the racetrack. "Since this change took place, we have seen increased horsepower from a higher-octane ethanol fuel blend and decreased emissions," says Chairman and CEO of Richard Childress Racing, Richard Childress. NASCAR also claims fans of the series are 80 percent more likely to use ethanol in their own vehicles than other drivers. Read more at Domestic Fuel.
Uptake in plug-in vehicles isn't dependent on customer knowledge of public chargers, according to a study from Simon Fraser University. Instead, researchers say home chargers are the key to more widespread EV adoption. This information is especially important for governments with limited funding that want to increase the popularity of electric vehicles. The study also found that customers showed more interest in plug-in hybrids and range-extended EVs than pure battery-electric cars. Therefore, the study suggests governments would do better to prioritize incentives over building public chargers.

A new national study conducted by SFU researchers suggests that home-based, rather than public, chargers are key to increasing electric vehicles' popularity
A Simon Fraser University Faculty of Environment researcher says a new study he conducted with graduate students has important implications for governments with limited budgets to support the electric vehicle market.
Jonn Axsen, an SFU School of Resource and Environmental Management professor, has co-authored a study that finds accessibility to home-based vehicle charging could do more to boost the popularity of electrical vehicles than public chargers.
Working with his graduate students Joseph Bailey, the study's lead author, and Amy Miele, Axsen found that awareness of public chargers has little impact on consumers' interest in electrical vehicles.
The peer reviewed journal Transportation Research Part D: Transport and Environment has published the trio's findings in their article in Is awareness of public charging associated with consumer interest in plug-in electric vehicles?
The researchers recently presented their study to the National Academy of Sciences' Transportation Research Board in Washington, D.C.
"When we account for the relevant factors, our analysis suggests that the relationship between public charger awareness and plug-in electric vehicle demand is weak or non-existent," says Axsen. "In other words, the installation of public chargers might not be the best way to encourage growth in the electric vehicle market.
"This finding is particularly relevant for British Columbia, which recently announced that it will revive the Clean Energy Vehicle Program, a program that supports the adoption of vehicles powered by electricity and other alternative fuels. The provincial government has yet to announce how renewal funds will be spent."
The study collected information from a representative sample of 1739 new vehicle buying households in Canada, with 536 from British Columbia. Respondents were asked about awareness of public charging in their region, and about their overall interest in purchasing a plug-in electric vehicle, such as a Chevrolet Volt or Nissan Leaf.
The data showed that British Columbia's Clean Energy Vehicle program-which installed almost 500 public chargers when the survey was conducted in 2013-was largely successful in increasing charger awareness. Almost one-third of British Columbian respondents had seen at least one public charger, compared to only 13 per cent of respondents in the rest of Canada.
However, that awareness didn't necessarily translate into increased plug-in electric vehicle interest.
The study found that future buyers are far more likely to be attracted to plug-in hybrid vehicles, such as the Chevrolet Volt, which can be powered by both gasoline and electricity. "Since cars such as the Chevy Volt don't rely only on electricity, potential buyers aren't concerned about public charging," says Bailey. "People can just recharge at home, and then drive wherever they want on any given day. The good news is that about two-thirds of car buyers already have some type of charging access at home."
"Given what we've seen here, it seems wise for governments to focus their money on incentives other than public electric vehicle chargers," says Axsen. "We know that purchase rebates can spark consumer interest, and we've shown that home charging is important. In combination with the implementation of a Zero Emissions Vehicle mandate like California's, these measures could be the biggest boosters of electric vehicle sales."

As Canada's engaged university, SFU is defined by its dynamic integration of innovative education, cutting-edge research and far-reaching community engagement. SFU was founded almost 50 years ago with a mission to be a different kind of university-to bring an interdisciplinary approach to learning, embrace bold initiatives, and engage with communities near and far. Today, SFU is a leader amongst Canada's comprehensive research universities and is ranked one of the top universities in the world under 50 years of age. With campuses in British Columbia's three largest cities-Vancouver, Surrey and Burnaby-SFU has eight faculties, delivers almost 150 programs to over 30,000 students, and boasts more than 130,000 alumni in 130 countries around the world.
