These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.

Old Toyota Camry Hybrid batteries find new life in Yellowstone

Beginning this fall, used hybrid batteries that would otherwise be recycled will get a second life in Yellowstone National Park. 208 nickel-metal hydride batteries are being retired from the Toyota Camry Hybrids they once helped power and will become part of an off-the-grid energy system at Yellowstone's remote Lamar Buffalo Ranch field campus. The Lamar campus provides field seminars and other education and research in the northeastern corner of the park. The energy stored in the battery packs will come from solar panels and micro-hydro turbines. The total storage capacity of the batteries is 85 kWh, which is sufficient to provide plenty of emissions-free power to the five buildings at the field campus. Toyota says this program essentially doubles the life of the batteries that are no longer suitable for driving. It's great to see the batteries get another life cycle before recycling, especially in a place where wild animals easily outnumbers the cars. The battery project is part of a larger partnership between Toyota and Yellowstone. Toyota has previously donated a RAV4 and $50,000 to support sustainability projects at the park. In addition to the energy system being implemented at the Lamar Buffalo Ranch, Toyota has taken part in similar energy projects. Beginning last year, Toyota dealers in Japan have been using hybrid batteries for power storage. Also, Toyota Motor Manufacturing Alabama is testing a system to use hybrid batteries to power operations and for emergency backup power. Learn more in the press release from Toyota below. Buffalo and Bears and Batteries – Oh My! Toyota Brings Power to Yellowstone National Park June 04, 2014 Yellowstone...Where the Deer and the Antelope and the Prius Play Torrance, Calif. (June 4, 2014) – The nation's oldest National Park is ready for some new power. Toyota Camry hybrid batteries will soon power the Lamar Buffalo Ranch field campus in Yellowstone National Park. It's a new lease on life for the batteries and new, zero emission, energy option for the Park. Now that's a "bear-able" solution! The stationary distributed energy system will feature 208 used Camry Hybrid nickel-metal hydride battery packs and a total storage capacity of 85 kWh, more than enough pluck to power the five buildings on the Ranch field campus.

Honda, Nissan and Mazda recalling 3 million vehicles for airbag inflators

Three million more vehicles can be added to the worldwide tally to be repaired for the faulty airbag inflators supplied by Takata. Honda, Nissan, and Mazda have all issued recalls to replace the bad part, including about 1.2 million of them in North America. NHTSA has been investigating all three companies, plus Chrysler and Toyota, for potentially affected vehicles.
Honda is recalling roughly 1.02 million Civic, CR-V, Odyssey and Element models In North America, built between April 2000 and October 2002. Mazda needs to repair 14,794 units of the RX-8 and Mazda6, and Nissan has 228,000 vehicles in North America to be fixed.
Chrysler is also starting what it calls a "regional field action" to replace the inflators in the 2006 Dodge Charger, according to a company spokesperson. The company says that it has not yet found the problem in any of its vehicles, but it's being done "out of an abundance of caution." The final number of Chargers affected will be announced later this week.
