Question

Write two advantages of classifying energy sources as renewable and non-renewable.

Answer 1

Hint: Renewable resources of energy are those, which are replenished naturally while non-renewable resources are those which are limited and may become extinct if used without care. Classifying energy sources as renewable and non-renewable provides us valuable information on their sustainability.

Complete step by step answer:
(i). Classifying energy sources as renewable and non-renewable provides us valuable information on their sustainability.
Classifying the sources as such gives us an insight into the limitations in using certain resources which are available to us in short supply. Coal, petroleum, natural gas etc. are some of the resources of energy which do not get replenished as frequently as they are consumed and hence their use has to be regulated and limited and are classified under non-renewable resources. Renewable resources are those, which are available to use at such a large amount and/or are replenished regularly. Examples of renewable sources are solar energy, tidal energy, geo-thermal energy, wind energy etc.
(ii). The given classification helps us in searching for alternate sources of energy.
As mentioned before, not all sources of energy are sustainable and available to us infinitely. And hence, their usage has to be regulated if they are to be conserved for future generations and alternate sources have to be discovered. The said method of classification gives us a statistical and geographical idea regarding their availability and sustainability. Hence, the usage of resources which are under the danger of possible extinction can be limited. More knowledge and information regarding alternate sources can be acquired and this further aids in locating renewable sources and harnessing them.

Note: Sustainability of resources is very crucial for betterment of our future generations. Though we have alternative resources that can be renewed or recreated time by time, we are still not capable of using these alternative, renewable resources with full efficiency. Therefore, we have used our limited resources carefully.
