General Motors is making noticeable efforts to break away from the “your-grandpa’s-car” notion previously attached to its name. It has done so, in part, with its production of 4 electric cars, which will totally redefine how you think of clean fuel vehicles.

GM recently unveiled two new models of electric cars at the 2015 North American International Auto Show: The 2016 Chevrolet Volt and the Chevrolet Bolt EV concept, joining the Chevrolet Spark EV and Cadillac ELR Coupe on GM’s roster of such vehicles. Ranging from superbly practical to downright sexy, it seems that GM’s rebranding and forward-thinking efforts have created something for everyone concerned with fuel efficiency.

1. 2016 Chevrolet Volt

Simply put, the Volt is “fun to drive,” according to Alan Batey, president of GM North America. He’s not alone, though, since Volt owners are some of the most satisfied drivers around, creating a bit of a cult-like culture among them. After all, this electric car is a three-time consecutive winner of the JD Power APEAL award. Owners report using the first generation of the Volt’s electric capacity roughly 80 percent of the time, but voiced an eagerness to increase that usage to 100 percent, which the 2016 model looks to achieve. Since fewer trips to the gas station is one step toward reduced oil dependence, this car is a well-suited match to we, as the brand has nicknamed us, “greenies.”

2. Chevrolet Bolt EV concept

Many are curious to know if the Bolt is simply a replacement for the Volt, to which Batey responds,“The answer is no.” Instead, the Bolt is looking to fill an affordability gap in the electric car market, which has been criticized for a sense of elitism among its options. With its $30,000 price tag, the Bolt is accessible to broader populations and won’t leave buyers won’t be short-changed. Given its 200-mile range, drivers can almost travel the distance between New York and Boston; that is, once all the snow melts.

3. 2015 Chevrolet Spark EV

A new set of eyes is on the Spark EV: East Coasters. In January, GM announced that the Spark EV will be available in the state of Maryland in the spring of 2015, expanding its presence to a bicoastal status (previously, according the model was only available in Oregon and California). The Spark EV offers yet another affordable option; after federal and state tax credits, the car will go for $17,845. The newer model is priced modestly higher, $19,185, but with its 82-mile range, it’s sure to make Beltway Bandits smile.

4. Cadillac ELR Coupe

The ELR, it seems, is GM’s response to the high-end Tesla, advertising a 300-mile range to match its $75,000 starting price tag. With the Tesla’s highest-end Model X currently going for $80,000, the ELR is beyond comparable, especially when considering that it beats Tesla’s 230-mile range. Also on our appreciation checklist is the efforts of GM to make an environmental appeal by a brand formerly known for an impressively geriatric customer base. Pink Cadillac? No, thanks. We’re more inclined to check out this green Cadillac.

Hybrid cars are all the rage. But are they really greener?

Some people might call my car a junker, but I roll around town in my 1997 Nissan 200sx with pride. That’s partially because I’m glad to tout my non-preoccupation with shiny new stuff, but mostly because my trusty little subcompact gets 35 miles to the gallon on the highway. That’s right—read it and weep, hybrid-SUV owners. The truth is that, despite the clever marketing, hybrid cars are not always greener than their traditional counterparts—and not just because of gas mileage.

First of all, let’s talk new versus used. Cars require factories to produce them, which require parts, which require raw materials…you get the idea. So that Prius uses a whole lot of energy and resources before ever seeing the sales lot. In fact, Wired magazine estimates that pollution-wise, building a new Prius is equal to burning 1,000 gallons of gasoline.

Given the wastefulness of auto production, it’s often better to buy a used car than a new one, even if the mpg is somewhat lower. Obviously a Hummer is a worse choice than a Prius in almost any case (unless that monstrous vehicle runs on biodiesel), but a car built a decade ago that gets around 30 miles to the gallon is greener than a new hybrid that gets 46 mpg, according to Wired.

Speaking of mpg, not every hybrid gets great gas mileage. The aforementioned SUVs range from 20 to 34 miles to the gallon, according to the U.S. Department of Energy. (Ahem, not quite up to par with my little 2-door.) Hybrid pickup trucks are even more abysmal, with Chevys and GMCs ranging from 20 to 23 mpg. Surprisingly, pricey luxury cars are the worst offenders: a 2013 Lexus LS 600h gets 19 mpg city and 23 highway, and the 2012 BMW ActiveHybrid 7 gets just 17 mpg city and 24 highway. Yep, that’s 17 luxurious miles per gallon driving on surface streets. But I bet it’s fast.

Despite the eco-unfriendliness of certain models, there are a fair number of hybrids with better mileage than most traditional cars. The 2013 Prius gets 48 mpg city and an impressive 53 mpg highway, while the 2013 Ford C-CMAX gets 47 mpg across the board. Interestingly, you can come close to these numbers with a true blast from the past like the 1986 Honda CRX HF, which gets 42 mpg city and 51 highway — but the repair bills could get steep.

So what’s an eco-lover to do? Emissions-free electric cars are a good choice, but only if you live in an area that produces clean power. Otherwise, think small and used. If you don’t want to risk something too old, a used hybrid might be a good idea. They’ve been out long enough now to hit the used-car circuit and get better mileage than many other options. Whatever model you go with, it’s crucial that you consider the ecological impact of your choice. Transportation emissions are responsible for most of the pollution in the United States, spewing toxins into the air we breathe and contributing to climate change — which affects all of us.

The post Are Hybrid Cars Really Greener? Not Always appeared first on EcoSalon.

Pass-fail classes were a gift. I mean, not when I thought I would ace them, because what would be the point? But when getting by wasn’t a sure thing (in my case, for example, in any class that ended in “ometry”), a thumbs up or thumbs down option was a super deal. I could fudge pretty much anything and how hard was it, really, to garner enough lackadaisical sentiment from the powers that be that said: “Whatever. Move along. You’re fine”?

Well, heads up automakers. Teach is onto you. The Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) are looking to take some of the vagaries out of fuel economy labeling by giving new vehicles grades for fuel efficiency. There’s even something on the table resembling a curve, where vehicles will be judged against the performance of their peers. Tough stuff and it won’t be surprising if The Industry doesn’t like what it sees.

The idea is to update the current label, “to provide consumers with simple, straightforward energy and environmental comparisons across all vehicles types, including electric vehicles (EV), plug-in hybrid electric vehicles (PHEV), and conventional gasoline/diesel vehicles.” The new stickers will now have “ratings on fuel economy, greenhouse gas emissions, and other air pollutants,” which addresses the requirements of the Energy Independence and Security Act (EISA) of 2007. The new label will be debut on vehicles in the 2012 model year.

For about the next two months, the agencies will be soliciting public comment before choosing between one of two proposed stickers. One is a bit more conventional (below), while the other bears the sure-to-be-controversial grading system (bottom). For the latter, according to the NYT, an A+ means a fuel economy equivalent of at least 117 miles per gallon and would be reserved for zero emission cars. Plug-in hybrids coming in between 59 to 116 miles per gallon would get an A, and “conventional hybrids, like the Toyota Prius and Ford Fusion,” would get an A-. The article goes on to say that if the system were in place today, “306 small cars from model year 2010 would receive a B, only eight S.U.V.’s would receive a B+ (68 would get a C), and the highest grade for a van would be a C+.”

Grades aside, a good old MPG ranking will be on whatever label ends up stuck on the windows of 2012 cars and trucks, as well as a “fuel consumption value” chart that measures gallons of fuel required per 100 miles. Egogeek points out that “upstream emissions, such as the emissions from a power plant generating electricity to recharge a vehicle, would not be listed on the label,” but there will a website offered where you can get more info if you want to check it out.

The NYT article is already reporting negative auto industry reaction, saying “the letter grades –  from A+ to D – were immediately denounced by some industry groups, which said the government should not be making value judgments for consumers about vehicles.” I suppose that’s to be expected by a group that’s not used to such getting graded so specifically on its work.

It’s going to be interesting to see how the grading system plays out, if that’s the route that’s chosen, as such an approach is always a delicate proposal. Witness the movie rating system where an NC-17 versus an R can make or break a film even before its release. The trick is going to be objective accuracy and if it’s done right, the carrot of a good grade might just be what’s indicated to get some of slackers in gear.

Aviation and space exploration suck – fossil fuel that is. Not to mention clean air, and quiet habitat. Can these industries, so essential to global scientific and economic progress, go green? The race is definitely on.

Offering hope, inspiring blog posts and tweets-a-plenty over the past two weeks were the test flight of Boeing’s 787 Dreamliner, which burns 20% less fuel than other passenger planes of its approximate size, and the unveiling of the world’s first, commercial passenger space craft, the SpaceShipTwo (SS2) by Virgin Galactic and Scaled Composites. SS2 is reportedly more fuel efficient than NASA’s spacecraft.

But such breakthroughs are just the start of what’s possible, in terms of fuel efficiency and other environmental advances, says Joe Parrish, vice president of research and development for Aurora Flight Sciences in Cambridge, Massachusetts. Aurora makes innovative aerospace products, including unmanned space vehicles, planes that can fit in your pocket, and planes with a 500-foot wingspan that can stay aloft for five years.

Working on the NASA N+3 “future commercial flight program” with Massachusetts Institute of Technology (M.I.T.), and the engine technology firm Pratt & Whitney, Aurora Flight Services’ research showed, in preliminary results, “that as much as 40% fuel reduction can be achieved through reduced cruise speed and redesign of aircraft,” Parrish reported.

In other words – a makeover and taking it easy!?

“You can’t take an existing aircraft and just reduce its speed to realize these environmental benefits. It’s not a matter of pulling back the throttle. But the redesigned aircraft does not look totally different from the old,” Parrish notes.

The more fuel efficient flying machine Aurora researchers envision (illustration, above) would be designed to cruise at mach 0.72 instead of the industry standard of mach 0.8. It would not have to use composite materials (which are lighter weight and used in the newly tested Boeing 787 Dreamliner) but it could use conventional aluminum and manufacturing technology, while still saving substantial amounts of fuel.

25% of costs for a typical airliner are spent on fuel, studies show. So the environmental benefits should deliver economic benefits, too.

Can the same efficiencies apply to space travel and space ships? As an industry, commercial space travel is too nascent to “go green,” Parrish says. But it is starting with a very ecological-minded entrepreneur, Richard Branson, along with pioneering spacecraft designer Burt Rutan. Branson famously supported and financed the development of alternative, renewable energy and signed the Clinton Global Initiative in 2006.

A report out on Wednesday (Dec. 16, 2009) from the American Lung Association showed “sixty percent of Americans live in areas with unhealthy air pollution levels,” even with new laws in place attempting to regulate and improve air quality. Every little bit of petroleum saved, and greenhouse gas emission avoided, helps.

Read up on the Boeing 787, and the SpaceshipTwo, and make your wishes for greener commercial and space flight known.

Basic Reading:

“With more than 300 future passengers already putting up the $200,000 for a seat on SpaceShipTwo, there appears to be a strong demand for the rides to the blackness of space…” – Wired.com

“Boeing’s first new aircraft for ten years represents a radical departure for the manufacturer, eschewing traditional aircraft materials in favour of composites, in the pursuit of efficiency and lightness. If the composites, comprising 50% of the aircraft by weight, do not perform as expected, major headaches could emerge.”- Center for Asia Pacific Aviation

“The [Boeing 787] Dreamliner will offer greater efficiency for airlines”¦ The plane [should] use 20% less fuel than today’s aircraft of comparable size, provide up to 45% more cargo capacity and include a new interior environment with cleaner air, larger windows, more stowage space, improved lighting and other conveniences.”- AviationRecord.com

This is the latest installment of EcoMeme, a column featuring eco news, tech and business highlights by columnist Lora Kolodny.

The post EcoMeme: The Future of Flight, Fuel Efficient? appeared first on EcoSalon.

Are fuel costs stressing you out? Can’t spring for a new fuel-sipping ride? When you seek to improve the fuel-efficiency of a vehicle, the journey must start inside your own head. When you learn to control emotions on the road, you reduce the impulse to stomp on the pedals. Eliminate those aggressive tendencies and you’ll experience a significant improvement in your vehicle’s mile per gallon (MPG) average.

Of course, while that mantra might sound swell and dandy, does it really work when you’re stuck in traffic twice a day, five days a week? It all depends on the strategies you employ.

Some things to consider:

Telecommute

Driving to work every day can be burdensome and wasteful (on many levels). Any opportunity you have to work from home is an opportunity to dramatically reduce your fuel costs and lower your stress level.

Use Flex Time

Leaving fifteen minutes earlier or later can have a significant impact on your commuting time and fuel consumption. Avoiding the worst of stop and go traffic during the morning and afternoon rush hours can boost your car’s average gas mileage.

Don’t Be In a Hurry

When all works as planned, those 15 minutes of slack in your schedule can prove to be quite relaxing. If you’re not in a hurry, you’ll go easier on the pedals.

Be Conscious and Conscientious

Know where your right foot is at all times. Seek to minimize the duration and intensity of the pressure you put on the accelerator. The more pressure you exert, the more fuel you’re wasting.

It Isn’t a Race

You don’t have to pass three cars on your way to the next traffic light. Let the other folks pretend that they’re driving in the Daytona 500.

Know Your Lanes

Be a good citizen on the highway. If you want to fly, the left lane is for you. If you’re traveling at the speed limit (or below), the right lane is where you should be…just be sure to make room for the folks that are merging. If it’s a three-lane highway, the center lane is for folks traveling through, at or above the speed limit, but below warp speed. A little courtesy goes a long way.

Stop Riding Those Bumpers

Unless you enjoy the exhaust smell of the vehicle in front of you, there’s no reason to crawl up its rear bumper (and raise everyone’s blood pressure). When you leave plenty of distance between cars, you reduce the need to stomp on the brakes, which leads us to…

Inertia is Your Friend

It’s been said that fuel-efficient driving is a lot like riding a bicycle. The more you can coast (with the automatic transmission in gear), the better. When you exert pressure on the pedals, you’re expending energy. The better you know your car, the more velocity you can safely carry through the corners.

Fuel-efficient driving needn’t be boring, nor should it infuriate your passengers or other drivers. Like so many things in life, some simple breathing techniques and a good bit of patience go a long way.

How often do you have to stop and fill up your tank? Frequent trips to the gas station may be a sign that you’re not maximizing your car’s fuel efficiency. As it turns out, trading your ride in for a hybrid isn’t the only way to improve your gas mileage. Here are some simple pointers to get started.

Lighten your load. Take out your golf clubs, toolbox and other heavy items when you don’t need them. Any extra weight reduces your car’s fuel efficiency.
Use cruise control as much as possible because driving at a constant speed increases your gas mileage. Plus, it sure makes that daily commute a little more bearable.
Switch into overdrive to decrease the engine’s speed and save gas.
Keep the idling to a minimum. Instead, turn off the engine while you’re waiting for your pals to pick up something from the store or finish getting ready.
Gradually accelerate to waste less gas.
Maintain your tire pressure to ensure that your tires are always properly inflated. In addition to better gas mileage, it will help your tires last longer.

Use the grade of motor oil recommended by your car’s manufacturer, whether it be 5W-30, 5W-20 or 10W-30.

Give your engine a tune up on a regular basis.
Only turn on the air conditioning when you’re dripping sweat and threatened by heat stroke. Okay, maybe that’s a bit extreme, but you get the idea. Use it sparingly.
Take off bike or luggage racks when you aren’t using them. They interfere with the aerodynamics of your vehicle and cause drag, which causes your car to expend more energy than necessary.
