The cost of rechargeable battery
power
Typical rechargeable batteries can be recharged about 200 times during
their lifetime. Assuming the costs of rechargeable batteries use on
average about 4 times more expensive than those primary batteries, one
can reduce the cost of battery power by a factor of 50 by switching
from primary to rechargeable batteries. Life-Cycle Assessment suggests
that additional environmental/societal costs should be considered for
rechargeable batteries. Comparing the primary and rechargeable batteries
on a one-to-one basis, the environmental/societal costs for the rechargeable
battery are higher (by roughly 50%) than those for the primary battery,
primarily because of the electricity needed to change the rechargeable
battery. More than half of the electricity in the United States is generated
by burning of fossil fuels (coal, oil and natural gas). Emissions from
the combustion include NO
x, CO
2,
SO
2 and other toxic trace metals, which are harmful
to the environmental and human health. Although it is difficult to estimate
the exact value of these environmental/societal costs associated with
battery charging by household electricity, the application of renewable
energy sources for battery changing world definitely reduce the energy
cost based on Life-Cycle Assessment techniques.
