ELECTRIC
CARS
Everyday,
we see so many cars on streets. For many years, cars have been using petroleum
as the fuel. One of the negative effects caused by the use of petroleum cars is
air pollution. This problem has been the main concern of many scientists. They
try to design cars which do not cause pollution. After doing researches for
many years, scientists now have invented electric cars.
Electric
cars have the same performance as petroleum cars. Electric cars can contain four
passengers. They are also equipped with radio, tape, and Air Conditioner (AC).
Even, electric cars are better than the petroleum cars in some ways. The size
of electric car engine is smaller then size of petroleum cars’engine. Electric
cars run more smoothly and they do not produce any pollution.
However,
there are some weak sides of electric cars. They are related to the cars’
energy source, which are the batteries. They are not effective. Electric car batteries
can only supply electricity for about three hours. After that, the car users
have to recharge the batteries for about five to ten hours long. Scientists
have tried to solve this problem and succeeded.
They
have invented new kind of battery but a new problem arises. The new batteries
cost a very high price which is about ten times more expensive than the price
of the old generation batteries. This results the high price of electric cars.
Therefore,
scientists keep on trying to find new ideas to produce electric cars with lower
price. They also try to make electric cars as comfortable as petroleum cars.
They hope that with the invention of cheap and comfortable electric cars,
people will choose to use electric cars and the scientists hope to reduce
pollution will become reality.
