Electric Cars
Hybrids vehicles, with their combination of both gas and battery power, represent 3% of the cars on the road today, up from zero just ten years ago. Fully electric cars like the Nissan Leaf and Tesla are mere curiosities, representing only 0.1% of all cars purchased in the U.S.
It might seem like a slow start, but electric cars will soon form the majority of all vehicles. Here’s why:
Except for early adopters of technology and diehard environmental customers, most people aren’t buying a fuel type, they’re buying transportation. They may want speed or economical transportation or family-friendly minivans, but how the vehicle is powered isn’t their main concern.
Examples like the Tesla have shown that electric vehicles perform on par with gas-powered cars. What limits their adoption then? Two factors: cost and range (and charging infrastructure, to a lesser extent, but that will be remedied when there is more demand).
The Nissan Leaf battery pack alone costs about $18,000 (though government incentives bring down the overall vehicle cost to the customer). When comparable gas-powered cars are about $20,000, the high cost of the battery pack alone is a huge barrier to widespread adoption, whether the cost passed on to the customer or the government, or hidden by the manufacturer.
Ramez Naam, author of The Infinite Resource: The Power of Ideas on a Finite Planet, recently explained that lithium-ion batteries have a fifteen year history of exponential price reduction. Between 1991 and 2005, the capacity that could be bought with $100 went up by a factor of 11. The trend continues through to the present day.
This exponential reduction in battery cost and improvement in battery technology, more than anything else, will affect both the cost and range of electric cars. By 2025, that Nissan Leaf battery pack will cost less than $1,800, making the cost of the electric motor plus battery pack less than the price of a comparable gasoline motor. Assuming even modest increases in storage capacity, the electric vehicle will rank better on initial cost, range, performance, and ongoing maintenance and fuel costs.
With both lower cost and better performance, electric vehicles will likely overtake gasoline-powered ones by about 2025.

Every jobs can bring for you a better future. Nowadays, there are many good jobs for you to choose. My ideal job is teacher. When I was a student, I used to dream of becoming a teacher because teacher are the persons that I always love and respect. They helped me very much not only in my learning but also in my life. It's a job that not easy to do because teacher is a holy job. When teacher want to help their students become sucessful and have a good future, they must try very hard to do it. I like this job because I recognized and understood what things my teachers gave me long time ago. Therefore, I wish I can become a good English teacher in the future. Despite being a teacher will earn less money than other jobs but become a teacher I can help many people. It makes my life meaningful. I will try my best to do that. And I hope that my dream will become true.
