Electric vs. Gasoline
Are electric cars better for the environment than gasoline ones?
Nowadays, people all over the world do their best to live greener and not contribute to global warming. An invention that is meant to help reduce the amount of toxic waste that is polluting the environment nowadays is that of the electric car. But is electric really so much better than gas? Electric cars are emission free, compact and lightweight, and three times as efficient as gas engines. Compared to gasoline cars, electric car motors are very efficient, converting over 90% of electrical power supplied into motion. Still, there is about a 50% chance in the United States that burning coal, which, in turn, severely harms the environment, generates the electricity that is used to charge the batteries of a plug-in electric vehicle. Another advantage of an electric vehicle, is its durability: except for the fact that it has lower emissions, the electric car is in no need for oil changes or tune-ups, and with regenerative braking, brakes last longer. The gasoline car, on the other hand, has to deal with part failures associated with belts, hoses and cooling systems. The gas-powered car has a fuel tank, which supplies gasoline to the engine. The engine then turns a transmission, which turns the wheels. An electric car functions just a little differently than the gas-powered one: in comparison, it has a set of batteries that provides electricity to an electric motor. The motor then turns a transmission, and the transmission turns the wheels. When it comes to safety, although the weight and the bulk of the batteries make the electric vehicle heavier compared to gasoline vehicles and takes up more interior space, it is proven that the occupants of a heavy vehicle will, on average, suffer fewer and less injuries than the occupants of a lighter vehicle.
Yet, although having an electric car has so many advantages, there are, as associated with all things, a few
