Give the
names of two energy sources that you would consider to be
exhaustible. Give reasons for your choices.
Give the names of two energy sources that you would consider to be exhaustible. Give reasons for your choices.
Two
exhaustible energy sources are as follows:
(a) Coal: It is produced
from dead remains of plants and animals that remain buried under the
earth’s crust for millions of years. It takes millions of years
to produce coal. Industrialization has increased the demand of coal.
However, coal cannot replenish within a short period of time. Hence,
it is a non-renewable or exhaustible source of energy.
(b) Wood: It is obtained from forests.
Deforestation at a faster rate has caused a reduction in the number
of forests on the Earth. It takes hundreds of years to grow a forest.
If deforestation is continued at this rate, then there would be no
wood left on the Earth. Hence, wood is an exhaustible source of
energy.
