Is Sustainability Really Sustainable?

Not too long ago, biofuel was the new buzzword for a potential future without dependence on fossil fuels. Since then, serious issues have come to light calling into question the real sustainability of this process.

Can we produce enough fuel?

As with resource recovery plants (refuse into energy), there is a concern about having enough raw materials to sustain processing efficiencies. It was found that most plants became very inefficient because there wasn’t enough garbage getting to the plant. In this case, can enough corn be grown, delivered and processed to maintain biofuel demand and efficiency for this expensive process?

Who’s producing the food?

So where are all the raw materials coming from? Farms. Seems like a no-brainer. If we can grow our fuel, then we have no worries. But there is much to worry about.

Unfortunately, the farms being used to grow corn and grain are diverting their crops to the fuel processing plants instead of supermarkets. As pricing normally follows a supply and demand model, the corn and grains that were used to feed livestock is now more expensive; the meat and poultry that eat the more expensive food is now increasingly expensive to purchase at the market.

Combine those expenses with the increase in fossil fuel prices— which fluctuate according to human whims than supply & demand— and there is a deteriorating situation to deal with. As people have less money and higher expenses, someone has to answer the question. Is this form of sustainability truly sustainable in this place and time?

The future may hold a different answer, but we all have to live in the now. What do you think?

The Electric Solution

Electric cars have made great strides in recent years, with the unveiling of the Nissan Leaf in August 2009 and the announcement of several more to be released in 2012, and have several advantages over their gas powered competition. Unlike traditional gas powered cars, electric cars have no tailpipe emissions. It is true that much of the United State’s electricity is produced by burning coal so the argument could be made that electric cars are only using a different form of fossil fuels and are, therefore, not a solution at all. However, aside from the fact that producing electricity is a lot cheaper and more efficient than the use of fossil fuels in combustion engines, new renewable sources of energy, such as solar or wind energy, are becoming more viable so that electricity will soon be a completely clean energy source.

However, while cars like the Nissan Leaf look promising, they are still a long way from fulfilling their full potential. At the moment electric cars have an estimated range at about 100 miles on a full charge. This would not be a large problem if charging was as simple as filling up at a convenient gas station. Even with a special L2 charger, the Leaf takes about eight hours to fully charge and a simple three pronged outlet will take a full seventeen hours. There is a level 3 “rapid recharge” option, but having the ability to interact with these stations, which takes less than half an hour, costs extra and cannot be installed at the customers home because it requires so much energy. This means that, while useful for most everyday uses, the Leaf is still fairly limited and road trips are essentially out of the question.

Ultimately, electric cars seem to be on the right track to justify the hope of fossil fuel independence, even if they are not quite there yet.

Why you should go for a used car

For some reason, the idea of driving a shiny new car with the plastic covers on the seats still on drives a lot of people crazy with excitement. You would love to show your new auto toy off to your friends, probably take your beloved on the first drive and feel proud when people ask you about your new car. You probably won’t be taking the seat covers off for weeks! However, once the ‘high’ of having bought a new car is gone, the reality of depreciation falls like a rock on your toe. You realize that, as soon as you drove the car out of the showroom, it suddenly lost a huge chuck of its value. Even if you try to sell the car off within a few months, you will lose a whole lot of money just because your car is ‘used’.

You could, however, be on the other side of the spectrum. You could be the one buying a shiny, barely used car whose seat covers have just been removed! People under-estimate the value they stand to gain by buying a used car instead of a new one. To begin with, a new car loses nearly 70% of its worth within the first four years. Most people try to dispose of their cars within 3 years of use just to get a slightly better re-sale rate. This is the reason why used car dealer lots are brimming with good as new cars waiting to be bought off for less than half their original price! We bet that doesn’t feel to good for the new car owner who just sold his expensive ride but it means that you could get a good deal on a great car!

However, you should try to contact individual owners instead of picking a used car from a dealer. They have lot of cars to sell and can afford to wait for the right price. Individual sellers are in a hurry to get rid of their old cars so you can strike a great bargain for a 3 to 4 year old car!

The Silent Warrior – Nissan Leaf

When one thinks of a hybrid electric car, most people think of a small car with crammed up interiors that accelerates so slowly that you might get booked for driving too slow! The reality is far from this presumption though. Electric cars can be as fast as any other gasoline car as the Tesla Roadster that clocks 60 miles per hour in 3.7 seconds proves. However, fast cars, whether hybrid or not, come at a high price. More affordable models are still viewed as being sub-standard performance wise, no matter how eco-friendly they might be. The Nissan Leaf electric hybrid seeks to break this assumption and does so with style!

Although not as fast as the Tesla Roadster, the Leaf manages a very respectable 60 miles an hour in 7 seconds. However, it not the acceleration of the Leaf that sets it apart from regular cars. The hybrid has fast gained repute for being amazingly silent! It gives the term ‘stand still’ a whole new meaning as you can barely make out a hum when it is idling. Even when on the move and when being accelerated, the only sound the Leaf gives out is the faint hum of its electric motor. With no engine vibration, the hybrid reaches its top speed of 90 miles per hour with comfort and still barely makes a sound unlike many luxury cars.

Even though the Leaf appears to be quite compact from the outside, the interiors are quite spacious although they may seem a little ‘bare’ to people who like fancy dashboards. The Leaf is quite a zippy little car and is great from driving around town and city driving. It accelerates at the slight push of the accelerator and cuts back on speed quickly too without making a sound. The hybrid feels very stead yet light and is highly responsive to controls. The number of miles you get on a single charge depends a lot on how you drive. A conservative driver can easily clock around 100 miles on a single charge, while the more zippy driver can get about 85 miles.

The Tech Savvy Nissan Leaf EV

Hybrid cars have been making waves in the automobile circuit with major manufacturers queuing up concept cars and prototypes ready to be launched in the near future. In fact, most automobile giants have already started the production on several hybrid series. One such hybrid car is Nissan’s electric Leaf. The neat and spacious 4 door leaf is not just an eco-friendly, cost efficient hybrid either. The car has to be one of the most tech savvy hybrid models available in that category of automobiles. As with all electric cars, the Nissan Leaf derives its driving power from a 24 kilowatt battery that uses electricity to charge itself. Tipping the weighing scale at 600 pounds, the battery pack is located in between the passenger seats of the Leaf. However, Nissan has taken their EV hybrid beyond the average electric car version by loading it up with hi-tech gadgets.

To begin with, the Leaf has a special iPhone application, that the Carwings telematics system uses to keep you informed about a whole lot of status updates from your Leaf. The system allows you to turn the charging of the car on or off as well as keep a check on the charging status. You can also use the cabin climate control to save up on some electricity and cash! The Nissan Leaf automatically sends you an email of SMS when it is fully charged so you can turn off the charging and not waste electricity on idle time. The Leaf’s charging time can also be pre-programmed so that you can utilize any off peak electricity rates that many states in the US offer during the wee hours of the night. In short, not only does the interactive communications of the Leaf make keeping a track of things much easier but also helps you save up some cash beyond the obvious fuel savings. The hybrid has a cool 7 inch touch screen control panel that you use to manage the audio system, navigation (GPS), charge status and climate control. The Nissan Leaf is sure to be a draw for a tech crazy generation!

Are Electric Cars the future of Automotive technology?

Internal combustion engine was developed in German Empire during the 1860s and 1870s and the first fully drivable automobile was invented by Karl Benz in 1885-1886 which was driven for long distances by his wife Bertha Benz.

Since then at least five major automakers including GM, Ford, Toyota, and Volkswagen have built more than 100 million vehicles over the last century and more than a Billion vehicles have been produced globally since the automobile was invented.

The four stroke internal combustion engine (ICE) has shown tremendous staying power over the decades as fuel injection, electronic valve control and other sophisticated developments have made ICEs improve fuel efficiency, power to weight ratio, and become ever more environment friendly.

However, even after 125 years since the invention, the most sophisticated vehicles only convert 10-15% of fuel into miles and the rest is wasted as heat, noise and other forms of energy.

Even hybrid electric cars which marry ICEs with modern lithium ion batteries are not as efficient as they could be and there is not even a single four door family car which can deliver more than 100 miles a gallon in city and highway driving.

Electric cars are the wave of the future since they are not dependent on any one fuel type and are solely dependent on the availability of electricity.

Therefore in principle, electric cars can run on electricity produced from coal, petroleum products, natural gas, methane, nuclear, hydroelectric, wind and even solar energy and can be very efficient in converting energy into miles.

Electric cars are also more amenable to national security since well populated regions such as Indian Subcontinent (25% of world population), China (20% of world population), Europe (7% of world population), North America (6% of world population) are self sufficient in coal, hydroelectric, wind and solar energy and this drastically reduces their dependency on petroleum imports.

Electric cars should focus on improving miles per battery charge before they become ubiquitous.

The Challanges The Electric Car Has To Overcome Before It Appeals To Families

Electric cars have a phenomenally long way to go before they become a viable competitor of gas-powered cars. There are many challenges that these car developers have to face to even come close to what a gas-powered car or hybrid offers. Perhaps, one of the biggest challenges is their distinct lack of appeal to families.

Electric cars rely on the weight to battery ratio in order to propel the car forward. In order to achieve a family-friendly design, they have to offer more than a two door compact model. But this presents a major problem for the electric car. More space means more weight added to the car. Weight is a major factor in the electric car propulsion. A heavier electric car is harder to propel forward. Thus much of the battery power is used on overcoming the friction to move the car.

Another feature that detracts from its appeal to families is the lack of range. Batteries can only last for so long before they completely drain. This means the electric car can only go so far before it loses its power. Usually, this is a few hundred miles. Any trip longer than that is out due to a distinct lack of charging stations. At this time, it is impractical for a family to consider a long distance trip.

While these are the major features that stop families from purchase, it is also the lack of amenities that give electric cars a solid thumbs down. Everything from the DVD players, the GPS, and the cell phone chargers require battery power. Which in turn, drains the batteries even more than just straight driving. There is a long ways to go before the electric car will appeal to families. At the moment, it is far too impractical to add such an impractical vehicle to the family driveway.
