I. INTRODUCTION
In modern times, having a fuelled car is essential in transportation. A gas powered car has a
fuel tank which supplies gasoline to the engine, the engine then turns a transmission which
by deflagration of gasoline (also known as petrol) or diesel. Both fuels are known to cause air
pollution and are also blamed for contributing to climate change and global warming.
The auto industry has the technology to address these concerns. It’s the Electric car. It has a
set of batteries that provides electricity to an electric motor. The motor turns a transmission,
Either of this two has advantage and disadvantages. A gasoline car produces a relatively
large amount of pollution and generally gets poor gas mileage. An electric car, however,
produces almost no pollution, but it can only go 100 to 200 miles between charges. And the
problem has been that the electric car is very slow and inconvenient to recharge.
This study shows which is better to use and more economical among these two, the
One of the largest contributors to air pollution and man-made global warming is
transportation. The Environmental Protection Agency estimates that the average passenger
vehicle produces approximately five tons of carbon dioxide (CO2) annually, which is thought to
contribute significantly to the greenhouse effect. Electric cars represent one alternative to
gasoline-powered vehicles and there are several key differences between the two technologies.
Features
The basic components that are required to operate a gas-powered car are an internal
injection system, spark plugs, a crankshaft and a battery. According to Hybrid Cars, the main
features of an electric car are an electric motor, a larger, heavier rechargeable battery, a
computerized controller and a regenerative braking system which is connected to both the
Function
you press the accelerator, gas is directed from the fuel tank through the fuel line to the engine,
where it is combined with air and compressed by a piston. The spark plugs ignite the fuel,
causing the pistons move. The motion of the pistons is transferred to the crankshaft, which
turns the wheels. According to Hybrid Cars, when you press the accelerator in an electric motor,
the controller sends a signal to the battery which tells it how much voltage to send to the
motor. When you press the brake, the electric motor slows the wheels and acts as a generator,
Cost
In terms of their initial cost, electric vehicles may be more expensive than their gas-
powered counterparts. According to Cars Direct, electric car pricing for 2010 vehicles ranges
from $15,000 to $100,000, depending on the make and model. Electric vehicles offer an
advantage in terms of maintenance costs compared with gas-powered vehicles. Hybrid Cars
estimates that electric vehicles cost approximately P1.02 per kilometer to operate compared to
Benefits
Electric cars are significantly better for the environment in terms of greenhouse gas
emissions and pollutants. According to the U.S. Department of Energy, electric cars produce
zero tailpipe emissions or air pollutants. They may produce emissions indirectly if they are
recharged using the conventional power grid versus solar or wind power. Electric cars are also
more energy-efficient than combustion engines, converting 75 Percent of the battery's energy
Considerations
While electric cars offer several advantages over gas-powered cars, there are several
things to consider before purchasing one. According to the U.S. Department of Energy, current
electric car battery technology limits their driving range to between 100 and 200 miles and it
can take up to eight hours to fully recharge the battery. Compared with the 300-plus miles you
can travel on a single tank of gas and the ease and convenience of refuelling, electric vehicles
ELECTRIC CARS
Advantages
The number one advantage of an electric vehicle is that no gas is required. One example
is the Chevy Volt. It has a battery range of 40 miles. That means it can drive for 40 miles
without using gas. 40 miles is more than the range of an average commute to work, so
you can go to and from work using no gas. With minimal gas usage comes great savings.
You do need gas in the Volt in case your battery runs out or you go for a long distance.
However, the amount of fill ups per year will be much fewer with an electric vehicle
You can plug the car into any outlet of the proper voltage and charge the car. Electricity
Electric cars give off no emissions. Electric cars are even better than hybrids in this
regard. Hybrids running on gas give off emissions, while electric cars are totally 100
Safety is a big concern with these vehicles. However, the fluid batteries actually take
impact better than a fully made gas car, and can help even more in the event of an
accident
Disadvantages
The first disadvantage is price. Electric car batteries are not cheap, and the better the
battery, the more you will pay. For example, the Chevy Volt has a 40 mile range and sells
for around $30,000. Compare that to the 250 to 300 mile range of cars made by Tesla
Even though it is a quiet ride, silence can be seen as a disadvantage. People like to hear
cars when they are coming up behind them or beside them, and you can't hear if an
electric car is near you. This has been known to lead to accidents
Most cars take a long time to recharge their batteries. Tesla Motors' Model S can
recharge in 45 minutes, but most electric cars right now take hours to charge. You can't
drive the car while the batteries are charging usually, so your car will be out of
Most electric cars currently on the road do not have long ranges. Although in the future
it will improve, most of the cars have a range of less than 25 miles, and you can't truly
see the great benefits until you ride in a vehicle with a longer range
GASOLINE POWERED CARS
Advantages
Cost
While the price of the technology needed for hybrid cars continues to fall, conventional gas-
powered cars still cost less than their newer counterparts. In part, this is due to high research
and development costs needed to bring a new hybrid system to market whereas gas-powered
cars use technology that has been around for more than a century and refined over the years.
Some hybrid models may also cost more to repair and maintain, especially if hybrid drive
components, such as the electric motor or battery pack, require replacement. Depending on an
individual driver's needs and long-term trends in the price of gasoline, the additional cost of a
hybrid car may or may not be offset by its fuel savings. In addition, hybrid cars are newer, so
there are fewer used models available at any given time. This drives up their cost and makes
used gas-powered cars even more appealing to drivers with limited budgets.
Range
Another key advantage of a gas-powered car is its range. For example, a car with a 20-gallon
gas tank that achieves an average fuel economy of 20 miles per gallon can travel 400 miles
before needing to be refuelled. This is far more than the range of electric vehicles, which may
use a small gas engine to produce additional electricity and extend their range to make them
practical for more drivers. Hybrid-electric cars will have a range that depends on how much
energy they can conserve during braking but still often have less range than gas-powered cars
Another advantage of gas-powered cars is when it comes to raw power. Some hybrid-
electric cars, especially early models, may compromise on power for better fuel efficiency. This
is a result of carrying the added weight of the batteries as well as the limited output of an
electric motor. However, gas-powered cars continue to become more powerful even as they
are refined to be more fuel efficient. Systems like displacement-on-demand, which allows a gas-
powered car to shut off some of its cylinders to save gas under certain conditions, give drivers a
Disadvantages
The Environment
Despite recent efforts to improve fuel efficiency and reduce toxic emissions in cars,
emissions have continued to increase steadily in the past two decades. When gasoline
combusts it releases the end products of carbon dioxide, carbon monoxide, and nitrogen
oxides, which may contribute to climate change. Even the infusion of 10% ethanol into gasoline
has not rectified the emission problem, according to Alpha Online, especially since the
conversion from ethanol to corn actually requires the use of fossil fuels.
Health
Gasoline exposure can occur from filling your tank, from a gas leak in your engine, or from
general spills and accidents. Gasoline can contaminate drinking water or nearby soil if you have
a well system or soil near your driveway. High levels of gasoline chemicals taken in from day-to-
day exposure like benzene may cause cancer, according to the Illinois Department of Public
Health. The long-term effects of occasional contact with gasoline are not as widely known, but
inhalation of the fumes can lead to dizziness, headaches, confusion and breathing difficulties.
It is quite widely known that the earth is running low on fossil fuels, which gasoline is a large
component of. Even though the estimates of geologists and oil companies predict that there is
a limited amount of oil remaining, their estimates may still be large exaggerations according to
Common Dreams. Since gasoline may run out in the next century, it is imperative to begin
making changes in the world fuel type. Other fuel types like hydrogen or solar power that do
not depend on fossil fuels may or may not be the answer, but coming up with a solution prior to
Oil Politics
It's strange to think that something as simple as what we put in our cars could have political
implications. Currently, the Middle East holds an extreme degree of authority in the world due
to the world's dependency on the oil deposits found in that region. Other world leaders have an
inordinately large amount of control as well because of oil, including Iran's Mahmoud
Ahmadinejad and Venezuela's Hugo Chavez, according to Market Watch. If a new domestic
power source for cars could be created and harvested, these foreign leaders and nations would
not have such a stranglehold on the rest of the world due to oil. It is thought that some of the
wars of the past few decades have been in part inspired by oil as well. Reduce the need for oil
and potentially the perceived need for combat will dissipate as well.
