At some point, the electric car will probably become a reality. For one, the perofrmance of electric cars is very high because of the large amonts of torque that the electric motors produce. Also, a benefit of electric cars is that they are exceptionally quiet. Electric cars are practical in some urban environments where one does not have to commute very far to work. stop and go traffic is what leads to a lot of fuel waste in today's society because cars get 0MPG when they are idling.
The electric car, though, will only make a comeback after certain criteria are met. First, the price of the cars must go down and cannot be subsidized by the government or car companies. Electric cars are very expensive today because fo the R&D costs. Another thing that must be improved is batteries. An electric car needs some way to store electricity, and modern day batteries cannot hold enough to take an electric car more than a few hundred miles before it needs to be recharged. Much of today's electricity is produced by burning coal and fossil fuel, so our electricity production must turn to renewable energy resources. Electric cars will drive demand for electricity, and may end up polluting the environment more if we continue to use fossil fuels do generate electricty. Also, when making electric cars, many toxic waste products are going to be produced, primairly when the batteries are created. Before a large investment is made in electric cars, we must first find a way to safetly recycle or dispose of depleted batteries.
