Energy-Meaning, sources, importance class 12
Looking for what is energy, sources of energy, and its importance in infrastructure chapter of Indian economic development class 12 CBSE
See, in this article, we would cover
- What is Energy
- What are the different sources of energy
- What is the importance of energy
Let’s first Discuss
What is Energy
See, economics is concerned about the production process and consumption activities. There is a requirement of input to carry out these two activities
That input is Energy
in Simple words
Energy is an important input for most of the production processes and consumption activities. It plays a crucial role in the development of an economy.
Energy, of course, is essential for industries.
However, energy is used in many areas nowadays.
It is used on a large scale in agriculture and other related areas like the production and transportation of fertilisers, pesticides, and farm equipment.
It is also required in houses for cooking, household lighting, and heating.
Definition of Energy
Energy is the most important component of economic infrastructure. It is the lifeline of production activity across all sectors of the economy.
T.R Jain
Energy is one of the key inputs for the growth of an economy
S.K Aggarwal
Energy is an important input for most of the production processes and consumption activities. It plays a crucial role in the development of an economy.

What are the sources of Energy
There are many sources of energy. Broadly sources of energy are classified in two different ways.
Case – I
Commercial Energy and Non-Commercial Energy
Case – 2
Conventional Energy and Non-Conventional Energy
Let’s understand this one by one.
What is Commercial Energy
Commercial Energy refers to those sources of energy that command a price and the users have to pay a price for them. In short souch sources of energy are sold.
Commercial sources of energy are exhaustible (except hydropower).
Examples of Commercial sources of Energy
For example, Coal, Petroleum, and electricity
What is Non-Commercial Energy
Non-Commercial energy consists of those sources of energy that generally do not command a price.
All Non-Commercial sources are generally renewable.
Example of Commercial sources of Energy
For example, firewood, agricultural waste, and dried dung.

What is Conventional Sources of Energy
Conventional sources of energy refer to the sources of energy, which are in use since long and can be stored.
In other words, Conventional sources of energy are those which have a long history of their knowledge and use.
Such sources are non-renewable resources of energy.
Even today, most of the industries of the world make use of coal and oil in industries.
Both commercial and non-commercial sources of energy are known as conventional sources of energy.
Examples of Conventional sources of Energy
for example, coal, and oil
What is Non Conventional sources of Energy
Non-Conventional sources of energy refer to the sources of energy, which have come into use only recently.
In other words, Non-conventional sources of energy are those sources that have been discovered or explored only in the recent past and which are yet to gain popularity for their use.
such sources are renewable resources of energy.
These types of energy resources are inexhaustible
Example of Non Conventional sources of Energy
For example, solar energy, wind energy, geothermal energy, bio-gas, and tidal power
