The world develops more and more quickly, while it is also polluted more and more seriously. Luckily, there are many ways to deal with the negative effects on the environment. One of these is driving an electric car. Electric cars produce about 80 percent less pollution than gas-powered cars.
Besides, electric cars have more benefits than gas-powered cars for several reasons. First, the energy of electric cars is regenerative , which means that when you brake（刹车）in an electric car, you can charge（充电）the battery again. However, when you brake in a gas-powered car, you actually use energy. Also, during producing electric cars, engineers spend more time and energy making electric cars lighter so that there will be less drag(阻力) from the wind. This allows an electric car to travel farther using less energy than a gas-powered car.
Driving an electric car can not only save energy, but also save more money and time. For example, it costs less to repair (维修)such a car. The cost of charging an electric car is about 20 percent of the cost of gas, and electric cars require less repair than gas-powered cars. This is because electric cars have no cooling systems and the other moving parts. There are fewer possible problems without the moving parts. Electric cars can also save people’s time. Gas-powered cars need to be checked in a few months, while all that you need to do is only replacing the battery every four years for an electric car. Now some people have begun to drive electric cars in several big cities of China. Though it may take a little time to get used to it, due to the great advantages, more and more people will use electric cars in the future.
