Are you aware that only about
15 percent of the energy in the fuel you put in your gas
tank gets used to move your car down the road or run useful
accessories like air conditioning or power steering. The
rest of the energy is lost. Clearly the potential to improve
fuel economy with advanced technologies is enormous.
What
can we do?

DRIVE ELECTRIC
CARS
Here are some reasons why:
1. Electric cars represent the
most environmentally friendly vehicle fuel, as they have
absolutely ZERO emissions. The energy generated to power the EV and the energy to move the vehicle is 97 percent cleaner
in terms of noxious pollutants.
2. Another advantage of electric motors is their ability to
provide power at almost any engine speed. Whereas only about
20 percent of the petroleum in gasoline gets converted into
useful work at the wheels of an internal combustion vehicle.
For an electric vehicle, 75 percent or more of the
energy from a battery reaches its wheels.
3. One of the big arguments made by industries against
electric cars is that EVs are still powered by power plants,
which are powered primarily by coal. Less than 2 percent of
U.S. electricity is generated from oil, so using electricity
as a transportation fuel would greatly reduce dependence on
imported petroleum. Even assuming that the electricity
to power the EV is not produced from rooftop solar or
natural gas (let’s assume it comes 100 percent from coal),
it is still much cleaner than gasoline produced from
petroleum! The power plants are stationary sources
that can be modified over time to become cleaner.
The major concerns facing the electric vehicle industry are
range, top speed, and cost. Ultimately, it’s the batteries
that will determine the cost and performance of EVs.
The price of modern high energy density Lithium battery
packs (ideal for electric propulsion) are reducing by almost
30-50% annually due to mass production efficiencies.
It will not be too long before these energy packs becomes
commercially acceptable for mass adoption.
The only way electric vehicles are going to make a big
difference in people’s lives is if they can do everything a
gas car can do and more. They have to both look great and be
safe to drive. |

Although electric cars perform
with good acceleration with generally acceptable top speed,
the lower energy density of production batteries available
today compared with fossil fuels implies that electric cars
generally provide lower range between charges, and
recharging could take significant lengths of time.
Currently, electric cars are suitable for shorter range
applications (city commuting within 100 miles). They are a
practical form of clean transportation and can be
inexpensively charged overnight. Electric cars can
significantly reduce city pollution as they have zero tail
pipe emissions. Depending on how the electricity is
generated overall vehicle greenhouse gases can be further
reduced. Electric cars are expected to have a major impact
on the auto industry given their role in reducing pollution,
reducing our dependence on oil, and the inevitable rise in
future fuel prices as global supplies are exhausted. |
