Are Electric Cars Really Worth It?

So this blog has some material in it while I work on getting content written for it, I'll be cleaning up a few argumentative essays I wrote for a class over the past few semesters. About the only change I'm making is getting rid of the parenthetical citations relevant to the class so that the essays read better in blog format. If you're curious about my sources, ask, and I'll be more than happy to share the relevant sources.

So, the world is warming up, the ice caps are melting, and we're using up the once abundant supply of fuel we have. As a result, people, and I am one of them, are starting to realise that we are going to need to find alternative methods of powering the way we move around, since the major fuel we use now just isn't going to last us. Enter the electric motor. Its proponents claim that it wil revolutionize the way we move from point A to point B, causing zero emissions, and as a whole, just being generally better than gasoline or diesel. Or will they? Some people aren't sure. They claim that the batteries just cannot hold enough of a charge to be of any practical use, they're too heavy, and take way, way too long to recharge, among a growing list of complaints. Depending on personal circumstances, electric cars work on a practical level for the average American.
One of the biggest practical issues with the electric car is milage. How far can I go on one charge? Obviously, if the owner works 50 miles away, and for whatever reason, the car can only make it 49 miles before needing a recharge, then no, it just will not work. However, the average American only commutes 32 miles a day between work and home. Meanwhile, the projected ideal milage from the three most prominent commercially available electric vehicles are all over 100 miles. Again the critics cry out, fixating on the "ideal" part of milage estimates. Nissan, at the very least, has an answer. They subjected their Leaf to a handful of different scenarios possible in the daily life of a car, to see how each situation would affect the charge milage. So, could one get to work and back without running out of charge before even making it to work in the morning? Well, unless you're of a small minority of Americans who commute long inter-city distances to work daily, yes. If you're one of those Americans who do commute long distances into work, you'd be better off looking at other options. Unfortunately, long trips in electric vehicles still do not work as well as one would hope.
Weight is always crucial in designing a car. The heavier a car is, the harder it is to get it going, stopped, and to keep it in control while in motion. Another downside to weight: the milage of the car decreases, sometimes rapidly. Back to the Leaf, since it is the most advanced and refined of the electric vehicles currently on the market. The curb weight of the Leaf is 3,354 pounds. Compare that to a similarily sized Nissan, the Sentra, which has a curb weight of 2,875 pounds, it is heavier by 500 pounds, most of which is due to the electric drive system. However, compare it to Nissan's flagship sedan, the Altima, and suddenly the weight doesn't seem so bad.
The one area where electric cars get crucified the most, even over their milage, is how long it takes to charge the batteries to full. Critics claim that the sheer amount of time it takes to return the batteries to a full charge state is ludicriously long, that they're just not practical. If you're charging your electric vehicle from a 110 volt circuit, then you'd have a point, charge times sail well beyond the 12 hour mark, some are even past the 24 hour mark. However, it must be asked, would you buy a Ferrari 485 Italia, and then run it on Regular Unleaded? It certainly would be cheaper. But, I wouldn't, I'd be filling it up with Premium to keep it running better, and get the maxiumum performance out of that V-12 engine. It's similar with charging the battery. A 110 volt circuit is to Regular Unleaded, as a 220 volt circuit is to Premium. Yeah, putting in a 220 volt circuit (let's face it, very few Americans have more than one 220 volt circuit in their home) can be costly, but if you're going to invest in electric, then you need to be willing to make the investment in the proper infrastructure to power your vehicle as well.
The fact of the matter is, the practicality of electric vehicles depends purely on the person. When compared to the average, they do start to make a lot of sense. Given the average commute distance of 16 miles one way, cars like the Nissan Leaf, the BMW Mini E, and even the Tesla Model S start to become rather enticing. The Nissan's ideal average range of 100 miles, or the Mini E's 109 miles (for some reason they couldn't get it to go the last mile and make it an even 110...), are plenty for your average American to go to work, get back home, and grab the kids and dinner along the way. Even some longer, inter-city commutes are possible, provided you live within 95 miles of your desk, and that you have a charge point with a 220 volt circuit available where you park your car while you're at work.
Having the crucial 220 volt circuit available both at work and at home is key. It drastically reduces charge time, and is actually reccomended by the manufacturers themselves. Looking up charge figures, there are multiple times, two 220 volt charge times with different amperages, and one 110 volt charge time. Take the Mini's for example. Official figures suggest that the Mini E can be charged in as little as 3 hours on a 220 volt circuit. Charge it on a 110 volt circuit, however, and the charge time skyrockets to 26.5 hours.
Making the decision to buy an electric vehicle is not an easy one. However, when all you look at is practicality, it starts to make sense, when you live within the car's range of your work. So long as we can live without making long journeys, or are able to afford an alternate method of making the journey, the electric car is indeed a viable replacement to gasoline. It's when long trips are required that the cars start to fall apart. The bottom line is, electric cars are wonderful for daily commuters, to and from work.
