Q. 7. On what basis would you classify energy sources as
(a) renewable and non-renewable?
(b) exhaustible and inexhaustible?
Are the options given in (a) and (b) the same?
(a) The sources of energy that are replenished by the nature are called renewable sources and those which are not replenished by the nature are called non-renewable sources of energy.
(b) The sources of energy that are present in a limited quantity and would get over after some time are called exhaustible sources of energy and those which are available in infinite amounts by virtue of nature are called inexhaustible sources of energy.
The options given in (a) and (b) are the same.
We should classify energy sources as (a) renewable and Non-renewable.
Renewable sources of energy are inexhaustible ; as non renewable sources of energy are exhaustible.
Thus option (1) and (2) are the same.
