Leaf vs Volt – Who is Winning Sales?
With six months of sales under their belts, which is coming out on top when it comes to sales in the plug-in EV battle?
Apparently the Nissan Leaf has the lead with 3,875 sold LEAFs so far in 2011 while Chevy has 2,745 Volts sold.
Granted they are different cars targeting different consumers with some overlap (see our Leaf vs Volt comparison article) and the Volt costs a pretty $8,000 more. To put it further into perspective, neither is even close to the Prius and hybrid vehicle sales figures- but that may change with time. › Continue reading
Electric Car Showdown – Chevy Volt vs. Nissan Leaf
It’s so exciting to have affordable full electric highway legal cars back on the market! Brings me back to the mid 90′s all over again. This time we have some choices with Chevrolet launching the Volt right around the same time the Nissan brings out the Leaf. While they are both electric cars, they are targeting very different markets with very different strengths. Lets break it down and see the important specs of each.
Chevy Volt
Going for the commuter and road trip crowd, Chevy is betting people will go for a all purpose car offering the most flexibility. It has a gasoline engine onboard to extend the range to 340 miles, but unlike the current hybrids, it will run exclusively on the electric engine for the first 35 miles.
Nissan Leaf
Targeting the commuter crowd and those with garages (for recharging), Nissan is betting on an expanding electric car infrastructure to provide recharging stations in the future. This car relies fully on its batteries for its longer all electric range, but also needs a longer charge time. However, if your daily commute is less than 15 miles both ways, it will last you all week before it needs a recharge, or just top it off every night.
The side by side:
| Chevy Volt | Nissan Leaf | |
| Range (all electric): | 40 mi | 100 mi |
| Recharge Time: (empty to full charge) |
10 hrs on 110v 4 hrs on 240v |
20 hrs on 110v 7 hrs on 240v |
| Power: | 111 kW (150 hp) | 80 kW (110 hp) |
| Top Speed: | 100 mph | 90 mph |
| Warranty: | Basic: 3 yr/36,000 mi Powertrain: 5 yr/60,000 mi Battery: 8 yr/100,000 mi |
Basic: 3 yr/36,000 mi Powertrain: 5 yr/60,000 mi Battery: 8 yr/100,000 mi |
| Price: | $41,000 ($33,500 after tax credit) | $32,780 ($25,280 after tax credit) |
Ford Focus Global Drive
In an effort to promote the Ford Focus, the Ford Motor Company is promoting a competition called Global Drive. While I am optimistic of future electric cars such as the Chevy Volt, I myself am a fan of this small, fuel efficient car until we reach that place.
Ford is interested in making contact with individuals passionate about environmental causes, with the intention of making several $10k donations to non-profits looking to “Start Something More.”
Ford is inviting people to create a simple video and submit it via the Ford Focus Facebook page. Selected participants, along with a friend, will get a free trip to Madrid, Spain on February 18-20th to test drive the all-new Ford Focus. Additionally, Ford will make a $10,000 contribution to your chosen charity in the categories of environment, education or hunger.

Government Vehicles Going Green
As some of you know, I work for a lab run by the Department of Energy. I get the opportunity to not only witness exciting research that furthers tomorrow’s sustainable lifestyles, but also to see the changes the federal government is making to make their sites as ‘green’ as possible. Current government regulations stipulate that “each agency shall reduce annual petroleum consumption by two percent each year from a FY 2005 baseline through FY 2020″. That might not sound like much, but that adds up to an over 20% decrease in petroleum over the next ten years! That’s a fantastic step in the right direction.
Federal institutions with more than 20 vehicles have also been told to “acquire Electric Vehicles (EVs) to replace gasoline vehicles in locations near facilities and parking structures with electric outlets, and High Efficiency Vehicles (HEVs) in areas with limited alternative refueling, or as appropriate”. In my lab, this translates to replacing all retired vehicles with electric, hybrid or alternately fueled vehicles, and phasing some vehicles out earlier than planned. We were even able to trade in some of our new Ford and Chevy trucks for brand new hybrids for a moderate fee. More electric outlets for vehicles have been added throughout the site as well. My favorite part of the recent changes: the bike trend. More and
more the federal institutions are making bicycles a part of their Federal Fleet. Around my lab, we’ve been acquiring bicycles for employees making trips to other buildings or job sites across our 426 acre campus. At first, a few employees complained when the vehicles weren’t available and we handed them a bicycle helmet and a key to the bike rack, but it’s catching on. People not only enjoy doing good for the environment, but enjoy getting off their butts and exercising during their workday.
Chevy Volt’s Battery Backed by Extensive Warranty

With the reduction of fuel consumption, car manufacturers focusing on the green consumer market have a new worry. Not surprisingly, car batteries simply don’t last quite as long in electric cars as car batteries did in the typical internal combustion engine cars. This fact, though incomparable to many other features of an electric car, is daunting for many an average consumer. In turn, it’s served as an obstacle to increase in sales in what may well be the future of cars.
For every market problem, there is generally a solution though. Either in clever marketing, research and development, or a combination of the two. And GM will be making use of both as it attempts to assuage consumer fears through a generous 8 year / 100,000 mile warranty. Only a short while back, GM became the first US automaker to run a battery pack plant, which is still building prototypes. And now, they’re already offering a warranty which applies to the popular Chevy Volt‘s battery. A warranty that the relevant GM press release accurately highlights as “the automotive industry’s longest, most comprehensive battery warranty for an electric vehicle.” › Continue reading
Platinum For Fuel Cells Gets Cheaper
The D
OE laboratory I work for recently published some promising results of one of our fuel cell experiments. Researchers with the Department of Energy’s SLAC National Accelerator Laboratory and the University of Houston recently found a way to get platinum to be more conductive. It doesn’t sound like much, but this is big for fuel cell technology. Anders Nilsson, one of the scientists involved explained that although fuel cell technology has been around for the past 100 years or so, it hasn’t been able to make any strides in the technology.
First, a little background on fuel cells. Fuel cells are the way we create energy from hydrogen. A fuel cell creates electricity from a chemical reaction involving oxygen and hydrogen. One of the most exciting things about fuel cell technology is that the only byproducts are two hydrogen atoms and one oxygen atom, also known as water! Platinum is currently the best catalyst we have to use with fuel cells. However if you’ve looked at the price of platinum recently, you know that the costs can be astounding for even just a plain platinum ring.
Many researchers have looked for ways around using a commodity as high priced as platinum for fuel cells. In 2008, researchers at Wuhan University in China found a way to bypass the platinum catalyst used in most fuel cells. They used a nickel anode and a silver cathode, and a powerful polymer membrane that can withstand the harshly acidic environment of the fuel cell. This acidic environment is the main reason that the high-cost precious metals are necessary in the first place. This polymer membrane has not yet proved to be even close in performance to platinum, but has proven that the idea itself has potential.
Rethinking Green Attitude

I want to reassure you here. I write for a green-living, environmentally conscious website. I’ve committed the past 5 odd years of my life to the study of and immersion into the world of environmental issues, policy, management, social movements, etc. I love the fact that I am likely to see a Prius on my way to work or the grocery store. But still, there was something that was bothering me about the scenario. And it didn’t take long to realize what was at the root of my problem. › Continue reading
Cash for Clunkers – Eco Friendly or Environmental Mistake?
There has been a lot of news about the Car Allowance Rebate System or ‘Cash for Clunkers’ program, but the real question is will this benefit the environment? Conceived as a two-birds-with-one-stone program to boost our economy and remove older polluting cars from our roads, but is it working? The real answer is that we don’t know yet.
The original program developed by Senator Dianne Feinstein, Democrat of California and Senator Susan M. Collins, Republican of Maine, required bigger improvements in MPG to qualify. Luckily it seems “the good judgment of the American people” has proved to exceed even the original requirements.
Transportation Secretary Ray LaHood said the average mileage of new vehicles purchased through the program is 9.6 miles per gallon higher than for the vehicles traded in for scrap. Buyers of new cars and trucks that get 10 mpg better than their trade-ins get the $4,500 rebate. People whose cars get between 4 mpg and 10 mpg better fuel efficiency qualify for a smaller $3,500 rebate.

We should stop and recognize, however, that Miles Per Gallon (MPG) is not a very good indicator of actual fuel efficiency, especially at higher numbers. Look at the table below, and you can see that if you traded a car that got 40 mpg in for one that got 50 mpg, you would qualify for the higher rebate, however, it would be less efficient (less of an environmental impact) than moving from a 20 mpg car to a 25 mpg car.
