Electric Cars: Pros and Cons



The burning of fossil fuels from vehicles will emit a variety of pollutants into the earth's troposphere. Two of the pollutants that are mostly emitted are hydrocarbons and nitric oxide. These pollutants can be harmful to all living life and the environment. Therefore, replacing vehicles having an internal combustion with electric vehicles is seen by some as a solution to this problem.


Comparing both types of vehicle, the electric vehicles is seen to be more environmental friendly and are less polluting compared to the internal combustion engine vehicle. This is because electric vehicles uses whatever electricity is delivered by their electrical grid operator. The source of electricity from the power grid can be drawn from renewable energy such as hydro and wind. Therefore, the electric cars are as clean as the grid. The electric vehicles also reduce greenhouse gas emissions and eliminate petroleum. Thus, it helps to reduce fossil fuel usage despite the fact that electricity is largely generated by fossil fuels. Because even fossil fueled-fired power plants are more efficient than a car's internal combustion engine, the electric car is more energy efficient and produces less overall pollution. Even using electricity from coal, an electric car is 4 percent more efficient than a gasoline burning version of the same car.

Other than that, because all cars required battery replacement eventually, the disposal of lead-acid batteries used in cars with combustion engine is more hazardous to the environment compared to disposing lithium or nickel-based batteries of electric cars. Electric cars also have a lower or no demand for many of the hazardous, polluting fluids used in a conventional car, such as motor oil. Electric vehicles typically have less vibration and noise pollution than a vehicle powered by an internal combustion engine, whether it is at rest or in motion. Therefore, people thought that it is better to replace the internal combustion engine vehicles with the electric vehicles.

Electric vehicles also have some disadvantages. If the internal combustion engine vehicle which is the conventional gasoline-powered vehicles for personal transportation is replaced by the electric vehicle, fuels production and import would switch from petroleum and its products to more coal, natural gas, nuclear, and many others. There would be more mining activities for the extraction of coal and uranium and less reliance on foreign oil. Apart from that, little that people know, electric cars can increase overall emissions of air pollutants particularly in rural areas. Sulfur oxides emissions are increased almost ten-fold by powering a car with electricity instead of gasoline. The same change in fuel also increases total nitric oxide emissions and particulate matters. These pollutants are the primary causes of acid rain.



I think, with some modification to the electric vehicles, it can help to abate the problems. With the advancement of technology nowadays, other alternatives and method of operating vehicles can be developed in order to protect our environment.

So guys, what is your opinion on this matter? Do you think electric vehicles are better than conventional vehicles?

  1. Dear FRIENDZ,
    It is important here to state that Environmental technology is a technology that is in the process of development and that any action taken to better the Environment is very important no matter how small it is.This article shows that at least there are some advantages or Environmental benefits for using electric car over a gasoline powered vehicle.I have tried to pinpoint these benefits and bring them out. The reasons why the electric car is more ecofriendly or environmentally friendly or more green than the conventional gasoline car are:
    1.The source of electricity from the power grid that powers an electric car can be drawn from renewable energy such as hydro,solar or wind.
    2.Because fossil fueled-fired power plants are more efficient than a car's internal combustion engine, the electric car is more energy efficient and produces less overall pollution. Even using electricity from coal, an electric car is 4 percent more efficient than a gasoline burning version of the same car.
    3.because all cars required battery replacement eventually, the disposal of lead-acid batteries used in cars with combustion engine is more hazardous to the environment compared to disposing lithium or nickel-based batteries of electric cars.
    4.Electric cars also have a lower or no demand for many of the hazardous, polluting fluids used in a conventional car, such as motor oil. Electric vehicles typically have less vibration and noise pollution than a vehicle powered by an internal combustion engine, whether it is at rest or in motion.
    For the above reasons,I think that switching from the gasoline car to the electric car is an ecofriendly move!!

  2. First of all this kind of car is so cheaper for man.because the fuel of that will be electronic and the motor of car deminish the usage of energy so,we are not under duress for recharging.
    Some kind of the car which if they alter new fuel(green),it will cause eulogy,is Formula car.
    The initiative demonstrates that Formula One’s teams and partners are backing the Make Cars Green campaign’s goal to reduce the impact of motoring on the environment.

    The connections between greener motoring and Formula One will be further strengthened next year with the introduction of energy regenerating hybrid devices, one of a number of initiatives in the sport that will be increasingly relevant to the car industry and help accelerate the use of fuel-efficient technology on public roads.
    over all,future must be green world otherwise,human will be destroy.
