What is less than 13 feet in length, appears to be smiling and able to do a 3-point turn in a single lane? Why, the latest green crazed Mazda 2 of course. Small cars often give off the impression of being cramped, unattractive and incapable of providing ample protection for braving major highways, but this pint size dose of delight makes a better impression then a certain overpriced two door burp of a car. Mazda introduced the 2 after a long hiatus from the subcompact class since the 323 way back in 1994. Designed with the same front fascia the current lineup displays, as well as the sporty feel we have come to expect from Mazda makes, this, oh I hate to say it, is cute.  Our Spirited green metallic 2 was nick-named Jelly Bean for her bubbly and adorable appearance.

There are no hamsters under the hood but don’t expect lightening quick quarter miles or impressive 0-60 times. The fuel-efficient, 100-hp 1.5L DOHC 16-valve 4-cylinder engine earns 27/33 mpg with an automatic transmission that will allow you to successfully merge into traffic without ever sounding like a john boat, yet resembles a sewing machine while idling and in normal driving speeds. 36-month/36,000 mile “bumper-to-bumper” warranty, 60 month/60,000 mile, 24-hour roadside assistance, ABS, DSC, TCS, advanced dual front & side impact airbags and curtains, “Triple-H” body construction round out the standard safety features. IIHS gave the Mazda 2 “Good” ratings in frontal offset accidents and roof strength, and “Acceptable” ratings for side impact and rear crashes.
 
The Mazda 2 is available in a Sport or Touring trim, MSRP starts at $14,180. Our 2 Touring version stickered in at $17,480. A uniform color of black with red accents on the upgraded Touring cloth seats did not appear cheap but of good quality making the cabin seem more spacious then the exterior leads you to believe. Your head won’t hit the ceiling and if you just so happen to be stuck in the backseat, you won’t feel as if you are stuffed in a clown car. The amount of space is generous for such a compact vehicle. The optional, generic arm rest ($170) should be included with the Touring package. Where else would your elbow go since there is no center console at arm level reach? Instead, there are three cup holder/stuff collecting compartments to place whatever your heart desires. The rear seat splits and folds flat, providing an ample 28.3 cubic feet of cargo space for large items. And thanks to the hatchback opening and width, there is still plenty of space to stash groceries or whatever else you carry with you. Round is the shape of choice from the instrument cluster, radio/a/c pod, leather-wrapped steering wheel with controls for audio/cruise much like the uniform color of the upholstery to make the interior cohesive while avoiding a cheap appearance.

Overall, the Mazda 2 provided the essentials in style, functionality and the very important “new car factor.” At a budget friendly price, this car is ideal for first time drivers or those wanting to join in on the small car class and take advantage of the concentrated “Zoom Zoom” Mazda is finally offering once again.

 Volkswagen revealed the all-new Passat at the Detroit Auto Show today as part of their growth plan for the U.S. market. The Passat may have been designed in Germany but will be manufactured at Volkswagen’s environmental conscience plant in Chattanooga, Tennessee.  The new Passat and the all-new Jetta are part of the divine plan Volkswagen has to significantly increase market share in the United States.

The new Passat is larger, and will offer features that American drivers favor and will be the only mid-size German engineered automobile with a price point starting at around $20,000 when it arrives later this year. Final pricing will be released this spring. The Passat will be available with three trim levels, S SE and SEL, with a total of 16 equipment levels and three engine choices:

2.5L five cylinder engine (170 hp/177 lb.-ft.), which is being offered in the Passat for the first time, will be mated to a standard 5 speed manual transmission or may be paired with a 6-speed automatic.

2.0L TDI Clean Diesel (140 hp/236 lb.-ft.) has the power of a six cylinder gasoline engine and the fuel economy of a hybrid. The Passat TDI is expected to deliver 43 miles per gallon on the highway, with a range of approximately 800 miles. Volkswagen’s TDI clean diesel engines, which come with a NOx storage catalytic converter, are among the cleanest engines in the world, fulfilling emissions requirements in all 50 states with an optional 6-speed DSG transmission.

 3.6 liter VR6 (280 hp/258 lb.-ft.) makes the new Passat a top-flight sport sedan. It offers power and luxury-class driving comfort, with European-type restraint in its fuel consumption — estimated at 28 mpg on the highway.

 Volkswagen hopes to set new records for safety, driving performance and environmental responsibility with the new Passat.

Even though the push to create green jobs is getting the lion’s share of business news headlines right now, almost $7 billion of the American Recovery & Reinvestment Act, the stimulus bill President Obama signed into law earlier this year, has been allocated to help businesses reduce their environmental footprints in any number of ways.

For starters, the stimulus package rewards businesses (as well as individuals) for investments in energy efficiency—that is, for doing more with less power. The federal government has extended its tax credit program for energy efficient business improvements—whereby 30 percent of qualified expenses up to $1,500 can be credited against your tax bill—through 2010. No one knows yet if the program will be extended beyond that, so 2010 could be a great time to finally go for that upgrade you’ve been putting off.

Qualifying upgrades include the installation of central air conditioners, heat pumps, furnaces, boilers, windows, doors and roofing that meet efficiency standards set by the government’s Energy-Star program. Likewise, the costs of upgrading to code-appropriate insulation and sealing as well as installing solar water heaters and biogas or biomass stoves also qualify for the tax credit. Business owners beware, though, that they can only claim a maximum of $1,500 combined for all efficiency-related upgrades.

Stimulus money—some $2.3 billion over the next 10 years—is also available to businesses, institutions and government agencies that green up their vehicle fleets and/or take steps to encourage or subsidize employees to go green with their commutes. Companies that install alternative fuel (ethanol, biodiesel or hydrogen) pumps on site can qualify for tax credits for between 30 and 50 percent of installation costs through 2010. Likewise, businesses that buy electric or plug-in hybrid cars or trucks for their fleets can score credits of between $2,500 and $7,500 per vehicle depending on battery size and fuel efficiency.

Another way businesses can make use of tax credits is to install on-site wind or solar power systems. The federal government will pay up to 30 percent of the set-up cost. Congress has also allocated $1.6 billion for Clean Renewable Energy Bonds (CREBs) to help finance construction of renewable energy facilities run by public utilities, electric cooperatives and city, state and tribal governments.

Businesses that qualify for any of the aforementioned tax credits should be sure to file IRS Form 5695 with their tax returns and keep all relevant receipts and copies of manufacturer certifications and Energy-Star labels where applicable. Tax advisors can provide more details on how to qualify for these federal incentives, and can also advise as to what additional incentives might be available from states. Be sure to check out the Database of State Incentives for Renewables and Efficiency (DSIRE), which provides a continuously updated list of both state and federal ways for both businesses and homeowners to save cash by going green.

Dear EarthTalk: I’ve heard that cars can be modified to run on water. How is this possible?

– Diane McMorris, Rockport, ME

There are a number of online marketing offers of kits that will convert your car to “run on water” but these should be viewed skeptically. These kits, which attach to the car’s engine, use electrolysis to split the water (H₂O) into its component molecules”"hydrogen and oxygen”"and then inject the resulting hydrogen into the engine’s combustion process to power the car along with the gasoline. Doing this, they say, makes the gasoline burn cleaner and more completely, thus making the engine more efficient.

But experts say the energy equation on this type of system is not, in reality, efficient at all. For one, the electrolysis process uses energy, such as electricity in the home or the on-board car battery, to operate. By the laws of nature, then, the system uses more energy making hydrogen than the resulting hydrogen itself can supply, according to Dr. Fabio Chiara, research scientist in alternative combustion at the Center for Automotive Research at Ohio State University.

Moreover, Chiara says, the amount of greenhouse gases produced by the vehicle “would be much larger, because two combustion processes [gasoline and hydrogen] are involved.” Finally, there is a safety consideration for consumers who add these devices to their cars. “H₂ is a highly flammable and explosive gas” he says, and would require special care in installation and use.

The electrolysis process could be viable in saving energy if a renewable, non-polluting energy source such as solar or wind could be harnessed to power it, although capturing enough of that energy source on board the car would be another hurdle.

Researchers today put more focus on using hydrogen to power fuel cells, which can replace internal combustion engines to power cars and emit only water from the tailpipe. And though hydrogen is combustible and can power an internal combustion engine, to use hydrogen in that way would squander its best potential: to power a fuel cell.

Hydrogen fuel cell cars are gaining traction, but commercialization of hydrogen fuel has not yet been accomplished. “The potential benefits of fuel cells are significant” say researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). “[H]owever, many challenges must be overcome before fuel cell systems will be a competitive alternative for consumers.”

The state of California operates a “Hydrogen Highway” program that supports development of hydrogen fuel cell technology and infrastructure. And many companies are working on ways to produce, store and dispense hydrogen. Cars powered by fuel cells are in prototype stages now, nearing production.

While we all wait to see how that shakes out, the best choice today for high mileage and low emissions is still the gasoline/electric hybrid car.

Dear EarthTalk: I’ve heard so much about using Borax for green housecleaning.‚  But if this mineral has to be mined, doesn’t that negate some of its “green-ness?” – Elsa, Lincoln, Nebraska

Mining for minerals such as boron (the key ingredient in the “Borax” we use for cleaning, pest control and other household tasks) is an activity that typically leaves behind a big environmental footprint. Mining degrades the local landscape and destroys wildlife habitat, while polluting both air and water. It also usually consumes large amounts of water, which can be taxing in already arid regions, such as the Mojave Desert, one of two regions of the world (along with parts of Turkey) with large boron deposits.

Typically, boron is extracted in open-pit mines by drilling, blasting, crushing and hauling”"all activities fueled by petrochemicals. The refining process then uses a significant amount of water. Finally, the waste product”"known in the industry as “tailings””"is deposited in man-made ponds where further refining is done before the water is then discharged into the local watershed.

The mining industry has long been criticized as an environmental baddie, but the leading company that mines Borax, Rio Tinto, has actually been given high marks for environmental stewardship. Jared Diamond’s 2005 book, “Collapse: How Societies Choose to Fail or Succeed” called the British mining giant the exception in its industry. Due to “a strongly supportive CEO and British stockholders” he wrote, the company moved forward with the 2002 environmental recommendations of the mining industry’s Mining Minerals and Sustainable Development project that were for the most part ignored by the rest of the industry. “Rio Tinto foresaw business advantages to being seen as an industry leader in social responsibility” said Diamond. “Its Borax mine in Death Valley, California is now perhaps the most cleanly operated mine in the U.S.”

Boron, oxygen and sodium make up sodium tetraborate, which is sold as “20 Mule Team Borax” (the name comes from the teams of 18 mules and two horses that would haul large wagons of processed borax from mines in the late 1800s to the nearest railroad spur). The powdered detergent is considered a least-toxic recipe as a natural disinfectant and household cleaner. Beyond cleaning formulations, boron is also used in a wide variety of other products, including the manufacture of fiberglass and Pyrex.

Pest control is another use. One boron compound is used to treat wood to prevent fungal decay and repel carpenter ants, roaches and termites. Boric acid is included on the national list of allowed substances for structural pest control in organic food production (as long as there is no direct contact with food or crops). The U.S. Environmental Protection Agency has determined that pesticide products containing boric acid and its salts are of low toxicity. (However, ingesting it or applying large amounts to the skin can cause acute poisoning, so parents should be vigilant about where they store and use products containing Borax.)

Emerging uses of boron, and new ways to recycle its waste, may make this mineral even more valuable. A Turkish researcher notes that borax waste added to red bricks and cement products increases strength and lifespan. And at the National Boron Research Institute in Turkey, it is being studied as an element to produce fuel cells and to aid in cancer treatment.

Dear EarthTalk: I’ve heard about the die-off of coral reefs due to global warming. I’ve also read that coral reefs themselves store carbon dioxide (CO2), one of the main global warming gases. So if coral reefs are dying out, isn’t that a double whammy that increases the CO2 in the atmosphere? – Tom Ozzello, Maplewood, MN

According to marine scientists, the world’s coral reefs—those underwater repositories for biodiversity that play host to some 25 percent of all marine life—are in big trouble as a result of global warming. Data collected by the international environmental group WWF (formerly World Wildlife Fund) show that 20 percent of the world’s coral reefs have been effectively destroyed and show no immediate sign of recovery, while about 50 percent of remaining reefs are under imminent or long-term threat of collapse.

Most scientists now agree that global warming is not a natural phenomenon but a direct result of the continual release of excessive amounts of CO2 and other "greenhouse" gases into the atmosphere by human industrial and transportation activity. And the small but prolonged rises in ocean temperature that result cause coral colonies to expel the symbiotic food-producing algae that sustain them. This process is called "bleaching," because it turns the reefs white as they die.

But researchers working with the Coral Reef Alliance have found that while coral reefs do store CO2 as part of photosynthesis, they tend to release most of it back into the ocean (so they are not what are known as "carbon sinks"). As such, the release of CO2 from dying coral reefs is not a major concern.

Of course, the ocean itself is a large carbon sink, storing about a quarter of what would otherwise end up in the atmosphere. Landmasses (and their plants) soak up another quarter of all the CO2 emanating from the Earth’s surface, while the rest rises up into the atmosphere where it can wreak havoc with our climate.

Recent findings indicate that the Antarctic Ocean is getting less efficient at storing CO2, and this raises serious questions about the ability of our oceans to handle everything we throw at them. The study’s authors fear that "such weakening of one of the Earth’s major carbon dioxide sinks will lead to higher levels of atmospheric carbon dioxide in the long-term."

Not everyone is forecasting gloom and doom. Some Australian researchers believe that coral reefs around the world could expand in size by up to a third due to increased ocean warming. "Our finding stands in stark contrast to previous predictions that coral reef growth will suffer large, potentially catastrophic, decreases in the future," says University of New South Wales oceanographer Ben McNeil, who led the controversial 2004 study that was published in the peer-reviewed scientific journal, Geophysical Research Letters. "Our analysis suggests that ocean warming will foster considerably faster future rates of coral reef growth that will eventually exceed pre-industrial rates by as much as 35 per cent by 2100," he adds.

In spite of such theories, the majority of marine scientists remain pessimistic about the future of coral reefs in a warmer world. One can only hope that the optimists are right.

Dear EarthTalk: Short of buying a new hybrid or other "green" car, are there ways I can make my existing vehicle more eco-friendly? I bought my car recently and am not quite ready to give it up. – Bettie Hilliker, Lansing, MI

Choice of vehicle may well be the biggest factor in determining the environmental impact of your automobile-based travels. But a considerable amount of energy is used—and pollutants emitted—in the production of any new vehicle, including hybrids and other more fuel-efficient options. As a result, many environmentalists believe that practicing good driving habits and performing adequate maintenance on an older car are probably better options for the environment than causing the production of a new vehicle.

According to the website GreenerCars.org, there are many ways to green up one’s driving habits. Obeying speed limits, utilizing cruise control and avoiding jackrabbit starts will maximize fuel economy and minimize tailpipe emissions while also preventing unnecessary wear-and-tear. Staying off roads during rush hours is also advisable, as stop-and-go driving burns excess gasoline and promotes smog. Opening vents and windows to cool off instead of using the air conditioner, an inherently inefficient appliance that consumes more fuel and leads to more emissions, is also good advice.

Drivers can also help minimize their environmental impact by keeping their cars well maintained. According to GreenerCars.org, getting regular tune-ups—where a qualified mechanic changes fluids and checks for and corrects problems such as worn spark plugs, under inflated tires, dragging brakes, misaligned wheels and clogged filters—can significantly improve fuel economy and minimize harmful emissions. GreenerCars.org also recommends seeking out low-rolling-resistance (LRR) replacement tires, which are specifically designed to improve a vehicle’s fuel economy, when the original ones wear out.

Beyond regular maintenance, a handful of small companies now sell green-friendly fuel additives that purport to increase fuel efficiency while reducing emissions. Such products—including Bluestar Environmental’s Omstar D-1280X gas additive and Suntec Bio-Energy’s diesel additive—are normally targeted at fleets of vehicles, but individuals are free to use them as well. Owners beware, though: Use of such products could invalidate automakers’ warranties, so read the fine print in your owner’s manual before pouring anything out-of-the-ordinary into your fuel tank.

Of course, getting out of your car altogether—or most of the time—is a far greener choice than driving even a well-maintained new or old car conscientiously. Some employers now offer federally-subsidized "commuter choice" incentives whereby workers can derive financial benefits by telecommuting (working from home), or by walking, biking, using public transit or carpooling to and from the office.

Another option is to join a car sharing service like Zipcar or Flexcar, whereby you pay a modest monthly membership fee and can then rent cars parked nearby by the hour only when needed. The companies operate on both U.S. coasts, as well as in major Midwestern and Canadian cities.
