Question

Read te passage below.
Production of latum-ion batteries is energy and resource intensive. Based on theme
parumeten the UCS has evaluated the life cycte vlobal warming emissions from
manufacturing, us and disposal of gasoline and electa cor While a mid size petrol
driven vehicle emits nearly 400 grams of Cose par mde during its-lifespan. it is about
200 grams of coa for a similar electric car,
Similar comparison holds for full sized cars. (Calculations are based on the average
American gnd electricity mixes in which fossil fuels constitute about 64 percent. In India
about 80 percent electricity comes from fossil fuels).
For both types of cars, the major portion of CO 2 equivalence arises from the operational
stage. While in the case of conventional cars it is due to burning the petrol directly, for an
clectric car it comes fro the use of grid electricity for recharging the battery pack. This
means that while an electric car is not entirely a zero emission vehicle, it is still far
cleaner dran a petrol vehicle.
With the global tendency to move away from fossil fuels to renewable energy resources
to Anerate electricity, this comparison becomes even more favorable to electric vehicles

The future
Though the running and maintenance cost of an electric vehicle is much lower than its
petrol counterpart, the weakest link in an electric vehicle is the traction battery. Presently
lithium-ion battery packs, which provide a DC voltage up to 500 W and a power rating of
anything from 18 to 50 kilowatt-hours or even more, are used. They cannot store as much
energy as petrol tank.
Manufacturers are working on alternatives to lithium-ion batteries like nickel metal
hydride (NiMH), lithium-nickel-manganese-cobalt, lithium-cobalt batteries, which can
have a higher charge density providing a longer ratge per charge (comparable to a petrol
car with full tank and also recharged faster. A Japanese automaker plans to release by
2022 electric cars that can run 240 km on a single 15 minute charge.
Another promising approach is the development of hydrogen fuel cells in which
hydrogen and oxygen undergo chemical reaction to produce electricity. The waste
product is just clean water. A fuel cell can provide a much larger driving range and
replacing hydrogen fuel cells takes only a few minute
