Would you like to have an electric car? We will see this kind of cars soon in America. These quiet, clean cars run on electricity. Carmakers will start selling electric cars in 2011.

The world’s population will jump from 6.8 billion to 9 billion by 2050. The need for cars will jump with it. But the oil(石油) won’t keep up with the number of cars on the road. So the price of oil will go up.

Electric cars aren’t perfect just yet. It can take eight hours to charge(充电) a car for only 100 miles of driving. And the distance(路程) that cars can go depends on driving conditions(条件). How far it travels depends on the weather and traffic.

Price is a problem, too. Electric models cost much more than oil-powered cars. The good news is that electric-car technology is getting better. As it does, the prices of this kind of cars are dropping.

To charge the car, the US Department of Energy is paying for at least 10,000 charging stations around the country. Private businesses are also getting ready for it. It will cost about $3 for each charge.

Carmakers are coming up with other ways to make the car cleaner and cheaper. Cars may run on clean diesel(柴油). So who knows what will power the car you may be driving in 10 years? The chances are that it will be something that’s clean and easy.
