Answer:

Classification of Energy Sources

All the sources of energy, currently available for harnessing,

can be linked to two fundamental forces in nature-

gravitational and nuclear. Nuclear fusion is the source of

solar energy - the driving force for much of the energy

consumed on earth today.

Renewability or non-renewability of a solar driven process is

distinguished based on the energy storage or cycling time

involved. Renewable resources have a cycling time less than

100 years, while for non-renewable resources, it is greater

than a million years. The depletable resources are fossil

fuels, which are non - renewable since the rate of their

utilisation far exceeds the rate at which they are formed.

Examples of renewable resources are hydro energy, solar

energy, wind, biomass, and energy from wastes (such as biogas,

agrowastes, etc.).

The renewable solar energy is subdivided into direct and

indirect types.Sunlight used directly can produce electricity,

heat or derive a chemical reaction. It is used indirectly

when it drives other processes, biological - chemical or

climatic - mechanical, which in turn are used as sources of

energy.

The energy sources can be classified in a number of ways

based on the nature of their transaction, as commercial and

noncommercial sources of energy . All energy resources,

particularly the commercial ones, are natural. Coal, oil and

nuclear sources constitute commercial sources, while firewood,

biomass and animal dung constitute non- commercial sources.

Also, the energy sources are classified based on animate and

inanimate characteristics.
