Essay On Electric Cars

An electric car is powered by an electric motor instead of a gasoline engine. The electric motor gets energy from a controller, which regulates the amount of power transmitted throughout the vehicle, based on the driver’s use of an accelerator pedal. The electric motors give electric cars instant torque, creating a strong and smooth acceleration pattern. Electric cars are about three times more efficient than cars with an internal combustion engine. A pure-battery electric car uses energy stored in the rechargeable batteries, which can be recharged by common household electricity. Compared with regular gasoline cars, electric cars do not produce tailpipe emissions, does not rely on gas, and are cheaper to operate. But of course the process of producing the electricity for these types of vehicles creates further upstream of utility company’s smokestack. Regular gasoline cars produce greenhouse gases and air pollution, which nowadays is one of the most critical environmental issues to people’s life. In the capital of China, Beijing, the air pollution is the most serious problem for the government. The particulate matter (PM2.5) factor is so high that it causes hazy weather in Beijing. The PM2.5 is around 151-200 in average, which can be defined as unhealthy for most days in a
The average range of an electric car is around 100 miles and the average range of a gasoline car is around 300 miles. Moreover, it takes hours to recharge the battery of an electric car, but it only take minutes to refuel a gasoline car. However, the cost between these two types of cars is very different, and that becomes the major reason why people choose electric cars instead of gasoline ones. The cost of an electric car is only 2 cents per mile while the cost for a gasoline car is 12 cents per
