Electric Car
The REVAi/G-Wiz i electric car charging from an on-street station in London. An electric car is a plug-in battery powered automobile which is propelled by electric motor(s). Electric cars have the potential of significantly reducing city pollution by having zero tail pipe emissions .[1][2][3] Vehicle greenhouse gas savings depend on how the electricity is generated. With the current U.S. energy mix, using an electric car would result in a 30% reduction in carbon dioxide emissions.
Given the
current energy
mixes in other
countries, it has
been predicted
that such
emissions would
decrease by 40%
in the UK,[8] 19%
in China,[9] and as
little as 1% in
Germany.[10][11]
Electric cars are
expected to have
a major impact in
the auto industry
[12][13] given
advantages in city
pollution, less
dependence on oil,
and expected rise
in gasoline prices.
[14][15][16] World
governments are
pledging billions to
fund development
of electric vehicles
and their
components. The
U.S. has pledged
US$2.4 billion in
federal grants for
electric cars and
batteries.[17]
China has
announced it will
provide US$15
billion to initiate an
electric car
industry.[18]
Nissan CEO Carlos
Ghosn has
predicted that one
in 10 cars globally
will run on battery
power alone by
2020.[19]
Additionally a
recent report
claims that by
2020 electric cars
and other green
cars will take a
third of the total
of global car sales.

Etymology
Electric cars are a
variety of electric
vehicle (EV); the
term "electric
vehicle" refers to
any vehicle that
uses electric
motors for
propulsion, while
"electric car"
generally refers to
road-going
automobiles
powered by
electricity. While an
electric car's power
source is not
explicitly an on-
board battery,
electric cars with
motors powered
by other energy
sources are
generally referred
to by a different
name: an electric
car powered by
sunlight is a solar
car, and an electric
car powered by a
gasoline generator
is a form of hybrid
car. Thus, an
electric car that
derives its power
from an on-board
battery pack is a
form of battery
electric vehicle
(BEV). Most often,
the term "electric
car" is used to
refer to pure
battery electric
vehicles.
