IASNOVA
Almost every year there is a question related to unconventional sources of energy such as Shale gas (2013 prelims), Coalbed Methane, Biogas , Geothermal energy, Fracking Process (all have already Been asked in past 5 years) . General sources of energy such as wind and solar energy are well covered in ncert and other standard textbooks .
Examples of PYQs –
Prelims 2018 Question-
With reference to solar power production in India, consider the following statements :
- India is the third largest in the world in the manufacture of silicon wafers used in photovoltaic units.
- The solar power tariffs are determined by the Solar Energy Corporation of India.
Which of the statements given above is/are correct ?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d)Neither 1 nor 2
Prelims 2017 Question
It is possible to produce algae based biofuels, but what is/are the likely limitation(s) of developing countries in promoting this industry?
- Production of algae based biofuels is possible in seas only and not on continents.
- Setting up and engineering the algae based biofuel production requires high level of expertise/technology until the construction is completed.
- Economically viable production necessitates the setting up of large scale facilities which may raise ecological and social concerns.
Select the correct answer using the code given below:
(a) 1 and 2 only
(b) 2 and 3 only
(c) 3 only
(d) 1, 2 and 3

With reference to two non-conventional energy sources called ‘coalbed methane’ and ‘shale gas’, consider the following ‘statements:
- Coalbed methane is the pure methane gas extracted from coal seams, while shale gas is a mixture of propane and butane
only that can be extracted from fine-grained sedimentary rocks.
- In India abundant coalbed methane sources exist, but so far no shale gas sources have been found.
