How Electric Vehicles Can Reduce Greenhouse Gas Emissions

Decent Essays

Electric cars are vehicles, which, instead of internal combustion engines, are driven by electric motors and controllers. They have proved to be a good substitute for conventional vehicles and are considered as a revolutionary innovation designed to protect the earth from the damaging effects of global warming, as they work on the electricity supplying the integrated rechargeable battery that can be easily recharged. Compared to traditional means of transport, electric vehicles seem to be more viable and environmentally friendly because they do not need oil or other fossil fuels as an energy source but the high cost of such a car and other important issues of exploitation discussed in this paper make their use very doubtful comparing to the usual cars. The studies have shown that electric vehicles can reduce greenhouse gas emissions to “6.12 billion tons annually” (Westbrook, 2001). Even though they need mainly coal as a supply of electricity, they produce less harmful emissions than oil, which is the main source of energy for transport modes, driven by gasoline (Westbrook, 2001). With the development of renewable energy technologies that use the power of wind or solar energy, people can get a clean source of electricity, which will make the electric car more friendly to nature. In addition, the introduction of “regenerative braking system” will allow cars to convert the force of inertia into electricity, thus, adding, extra batteries, which, in return, increase its
