Although governments
and the general public feel that the electric car will be of great help in
reducing global warming, some scientists are actually questioning such facts:
They would like to know:
·
How electric
cars and their batters are and will be manufactured in future
·
The production
method of electricity which will charge the cars
Research in Norway has
found that the possibility exists that in exceptional circumstances, electric
cars will have a greater impact on global warming than conventional cars. One
of the authors of this report Guillaume
Majeau-Bettez, of the Norwegian University of Science and Technology has
admitted that their research findings do not favor the electric vehicle. He
contends that electric cars might have a great future, but eventually its
success will lie in how much we can clean up our electricity network
for the electricity that is going to be used in the production of the car and
the electricity that will be needed for charging its batteries to make it run.
Tests will be
carried by driving the electric car and the conventional car for 150.000km.
Scientists will then take into account the energy that is needed to refine and
transport oil into petrol and diesel. One result was that the electric car is
energy intensive and some electric cars impact the environment considerably
more than conventional cars. This is because of the raw materials and energy
that is essential for building lithium-ion batteries. However, despite these
controversies about how electricity is generated, the car is being in most developed
countries. The charging of the batteries is also dependent upon the time of day
that the batteries are being charged because the electricity that is generated
during the daytime is less dependent on coal. In During 2012 the generation
of electricity from coal actually increased
because of the high prices of gasoline. However, coal is more polluting than gasoline
and in China since most of the electricity is produced from coal, pollution
from electric cars is actually far more polluting than conventional cars. In
comparison, in a country like Norway where most of the electricity is produced
by hydro power, electric cars performed much better than conventional cars in
their environmental impact.
