Since man discovered the wheel and learned to ride a horse, transportation has become an essential part of civilization. Although the popular cars in the market today make full use of gasoline, it was not always so. In the early twentieth century, almost all cars were actually running via electricity (Smith 2008). Like the electric ones being invented and sold currently, these had no emissions, had quiet engines and ran smoothly.

However, good marketing and sales eventually favored gasoline-run automobiles. With the rise of prices of fossil fuel and higher awareness for what carbon dioxide emissions can do to the environment, electric cars are once again stepping into the limelight. Although politics and capitalism have been trying to downplay the practicality of electric cars, one will soon come to see that its merits really cannot be set aside. Not only is it non-pollutant but also inexpensive and safer to use.

Environmentalists have been waiting for car manufacturers to return to marketing cars that do not emit carbons into the atmosphere. Vehicles ran by gasoline produce carbon dioxide which is not only unhealthy to those who inhale it but also traps the heat of the sun from escaping the earth. This issue is more popularly known as global warming. Electric vehicles (EV) do not emit tailpipe pollutants although some critics say that the coal-burning power plants that process the electricity do contribute to pollution (Electric Vehicles n.

d. ). However, environmentalists come to EVs defense by saying that recharging these cars from coal burning plants will still decrease carbon dioxide emissions between 17 to 22 percent (Coal vs. ICE 2007). They also argue that it is much easier to control the pollution from a lesser number of plants compared to managing millions of individual vehicles. Recharging can also be done through other electric sources like solar, nuclear, wind and hydroelectric utilities. Electric cars are also conservative in using energy.

The same article cited above referred to a study made by the Los Angeles Department of Water and Power which showed that the electricity converted by EVs into mechanical energy produced less than a hundred pounds of pollutants compared to the 3000 pounds being made by gasoline-powered automobiles. This is due to the use of lead-acid batteries and other types being developed that would make the EVs more efficient and safe to use. Hybrids, another type of electric vehicle also use regenerative breaks that conserve energy.

Although hybrids use a mixture of fossil fuel and electricity to create a gas that would run the vehicle efficiently, it is still less polluting compared to the conventional car (Smith). The motors of hybrids convert 75 percent of the energy from its batteries to power the wheels while conventional cars are only able to process 20 percent of the energy from gasoline (Electric Vehicles). Thus, hybrids are still more economical in terms of using gasoline compared to internal combustion engines (ICE). But how economical are EVs compared to ICEs in general?

There are many given estimates by different users to show how economical EVs would be compared to ICEs. Supposing that the price of electricity is at 8 cents per kilowatt-hour and it takes 12 kilowatt hours to recharge the car that will run for a minimum of 50 miles. It will then cost an EV around . 02 cents a mile compared to the average ICE which uses around 4 cents worth of gasoline per mile. (How Electric Cars Work 2008) Another user has a full webpage called Gas / Electric Vehicle Cost Comparison which shows that after gasoline and maintenance costs, an ICE will have cost the owner $971.

33 a year while an EV will only cost $473. 74. Electric vehicles are also cheaper to maintain. The standard ICE engine is estimated to last around several hundred thousands of miles before it conks out even with great care while an EV engine will last millions of miles (Good Reasons 2007). The same article mentions that EVs have only one moving part which makes it less cumbersome to decipher where problems can prop up while gasoline cars have spark plugs, fan belts and so many other things to replace and produce problems for drivers.

There are critics who say that electric cars can also be costly when it comes to battery replacement. The average EV battery needs to be replaced after around 400 to 500 charges and the price is at a range of $3,000. However, there are many developments happening in this problem area and scientists are finalizing their project on fuel cells that they say would reduce the cost of battery replacement to only $2,000 (How Electric Cars Work). There are also those who feel that the cost of electric vehicles is too high because of the average $30,000 to $35,000 price tag.

However, if one will compute for the savings it can give back, one will surely be in favor of EVs. There are also people who criticize electric cars because it is much slower than its internal combustion engine rival. The speed of the average EV is 50 to 60 miles per hour while conventional gasoline-powered ones obviously go much faster than that. However, the average American driver goes for around 50 miles per hour so it should not really pose as a deterrent to those who wish for a more ecological type of car.

Others also feel limited by the range EVs can drive which is at around 50 to 100 miles per recharge. Hybrids go faster than purely electric cars which is also why others prefer it even if these cost much more. Electric cars are a blessing not only to environmentalists but to normal consumers who have become so dependent on fossil fuel. It is a relief for many EV owners to know that they simply have to recharge their cars at home compared to stopping every so often for fuel from distant gasoline stations.

Electric vehicles, whether purely run by electricity or with the aid of gasoline are cheaper when it comes to energy and maintenance. It is definitely financially wise to own one.
