Hybrid Vehicles:
Friend or Foe?
By Lizzie Johnsen
and Julie Samuelson
What are hybrid vehicles?

Type of car that uses
a combination of
small gas engine and
electric battery to
power car
History of Hybrids
From 1897 to 1907 the Paris Electric Car
Company produced a series of hybrid and
electric cars
 First hybrid created in United States was
by engineer H. Piper on November 23,
1905
 From 1890 to 1920 there were more than
100 different makers of hybrid cars

How Hybrids Work




Use combination of gas
motor and electric battery
At low speeds or
coasting, the car runs on
electric energy
At fast speeds, the car
switches to its gas engine
If the car is not moving
the engine automatically
turns off, using no energy
Hybrid Effect on Atmosphere

Releases fewer emissions into atmosphere
– emissions: gases and particles released into
the air as byproducts of a natural or manmade process (www.mtpc.org)
– Emissions pollute the air and contribute to the
thinning of the ozone layer
– Fewer emissions are less damaging to
atmosphere
Benefits of Hybrids

Make us less
dependent on
other countries for
oil
– Uses less oil
– Makes us more
self-sufficient
Benefits of Hybrids

Reduction in gasoline
needs
- Less of a need for
gasoline
- Saves the owner of
the car money
- This is crucial as gas
prices continue to rise
Benefits of Hybrids

Battery pack can
recharge
– Receives energy
from break friction
– Capable of storing
energy
Benefits of Hybrids

More eco-friendly
– Does not harm the environment as badly as
traditional gasoline cars
– Releases fewer toxins
– Keeps air cleaner
– Much quieter than gas cars
Flaws of Hybrid
Significantly more
expensive than
regular cars
 Battery not included
in overall cost
 Battery is expensive

Flaws of Hybrid



Batteries still need work
Die about every 3 years,
expensive to replace
Made with lead and nickel
– This makes the batteries
toxic
– Can be hazardous if they
leak
– Can cause deformities and
diseases in people
– Batteries can take up to 10
hours to fully recharge
Flaws of Hybrid

Higher chances of breakdowns
– Uses new technology that has not been
mastered yet
– Sometimes unable to detect errors in car until
it stops working
– Hybrids have 2 motors, so the chances of one
of them not working is doubled
Flaws of Hybrid

Lack of raw materials
– Many parts would have to be imported from
China
– Increases our dependency on other nations
Flaws of Hybrids

Technology too
complex
– “Cutting edge”
technology is more
advanced than
common people
– Many mechanics don’t
understand it
Hybrids in the Media
Many people are misinformed about their
views on hybrid cars
 Car companies use marketing and their
credible reputations to persuade people to
buy their cars
 GM, Ford, and Chrysler recently urged
President Bush to financially and politically
support a national technological solution
involving hybrids

Are they a realistic future?
Although they are a good solution for right
now, hybrid vehicles are not sustainable in
the long run
 Only a “quick fix”
 Their technology is too complex and their
cost is too expensive for the general public
 Research shows that they will not be able
to be mass produced until 2025
