We certainly took some sort of transportation like the trams or buses that was powered by electricity before. What is perhaps less well known is that the first battery powered vehicles were on the market in the early 1900's. At that time, these battery powered carriages can travel a maximum speed to 14 miles per hour and can do a distance of approximately 18 miles. The popularity of this type of vehicles decline when the vehicle that is powered by the combustion engine was introduced.
As time goes by, the issue of global warming is getting more attention. The prices of oil have gone up tremendously. These factors, together with the realization that the earth's reserves of oil will run out within the next few decades, have led to renewed interest and research into electric vehicles. These vehicles have several major advantages over gasoline powered vehicles.
The motors that power these vehicles emit no noxious exhaust gases. This is definitely a good thing when we have countless of other pollution that is doing harm to the nature. These carbon dioxide emissions are seen as contributing significantly to global warming, while other exhaust gases increasingly pollute our air.
If you compare electricity with gasoline, electricity will much cheaper. They will become more economically viable as the price of crude oil continues to escalate. It has been estimated that the energy required to run an electric car is approximately one fifth that required to run a gasoline powered car. As the price of oil continues to rise, this gap will get bigger.
With nbattery powered cars, there will be less maintenance as well. They do not need regular oil changes and are not subject to the same wear and tear as internal combustion engines. In addition they have far fewer moving parts that need to be maintained.
The major disadvantage at this stage is the limited range made possible by current battery technology. With electric cars, you can travel up to two hundred miles and you will have to recharge for several hours before you can continue your journey. Like any other batteries, it can only be recharged for a certain amount of times before it need to be replaced.
Batteries are expensive and that is why electric cars are costly. Surveys have revealed that US and English consumers are not willing to pay more for an electric car with limited range, and this inhibits the mass transition from gasoline to battery powered cars. We will definitely see more electric cars on the road as technology improves. The cost of electric cars will be lowered when here is mass production.
So, there are advantages as well as disadvantages for both gasoline and electric cars. It is, however, becoming very clear that our current rate of oil consumption is not sustainable (in terms of cost, availability and pollution) and that sooner rather than later we will have to find a viable alternative. Electric cars seems to be the only solution.
