The Pros And Cons Of Electric Vehicles

5561 - A World with Only Electric Vehicles Today our lives are thought to be in danger due to global warming. Global warming is defined as a gradual increase in the overall temperature of the earth's atmosphere caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. Thought to be a big contribution to global warming are the emissions that come from the exhaust of our cars. Electric vehicles do not have tailpipes that exhaust fumes to pollute so they are the logically thought of the cleaner form of transportation. Imagine if everyone suddenly had electric vehicles, would we be able to provide enough energy to power them all? If not how much more do we need to make it possible and will the way we produce the energy pollute just as much as the fossil fueled vehicles they replaced? Electric cars are common to see on the road and it is also common to find changing stations in parking lots. Since it has not been common until recently, electric cars feel like a new idea but they have been around since the 1800s. In 1832 Robert Anderson developed the first crude electric vehicle that is not practical. William Morrison created the first successful electric vehicle in
The biggest difference between gasoline and electric vehicles is the engine. Instead of an internal combustion engine the electric vehicle has an electric motor. Also instead of gasoline as fuel an electric vehicle uses batteries for energy. Finally, instead of injecting fuel into the motor the electric car has a motor controller that takes power from the batteries and delivers it to the motor. With different components the vehicles function differently. The accelerator pedal in an electric vehicle is connected to a pair of potentiometers which provide the signal that tells the controller how much power it is supposed to deliver. The power delivered translates to the speed of the
